Signs, Symptoms, Diagnosis, Treatment & Prevention

Overview

How serious is a spider bite?

Most spiders are harmless and rarely bite people. All spiders make venom (a poison), but most spiders’ fangs are too small to puncture human skin.

Spiders are arachnids (not insects). They’re in the same class as scorpions, mites and ticks. All of these arachnids have eight legs. Spiders perform a vital function by eating insects that can destroy crops.

Which spiders are dangerous to people?

There are at least 60 different spider species in America, but only a few pose any danger to humans. These more dangerous spiders include:

  • Black widows: These black spiders have a red hourglass shape on their bellies. Black widows like to build webs in woodpiles, building overhangs (eaves), fences and outhouses. They mostly live in the Western and Southern U.S.

  • Brown recluses: Sometimes called fiddleback or violin spiders, these brown spiders have a dark, violin-shaped mark on their heads. Brown recluses live in Midwestern and Southern states. They like dry, sheltered areas, such as piles of wood, rocks and leaves. Indoors, brown recluses seek out dark closets, attics and shoes.

Brown recluse spider

  • Hobo spiders: These brown spiders have a grey V-shaped (herringbone) pattern on their bellies. They build funnel-shaped webs in dark, moist basements, crawl spaces, window wells and woodpiles. Hobo spiders are mostly found in the Pacific Northwest.

How common are spider bites?

Experts aren’t sure how many people get spider bites every year. Most of the time, you may not know a spider bit you. Or you may think an insect bit you, instead of a spider.

Bites from black widows or brown recluses are most dangerous to children (because of their small size) and the elderly (who may be frail or in poor health). In the U.S., fewer than three people die every year from a spider bite. Most of these deaths occur in children.

Who might get spider bites?

Anyone can accidentally come into contact with a spider and get bitten. Still, some people may be more at risk because their jobs or actions put them in closer contact with places where spiders live. People at risk include:

  • Outdoor workers, including landscapers, groundskeepers and farmworkers.
  • Children who play in piles of leaves or rocks.
  • Hikers.
  • Janitors.
  • Machine operators.

Symptoms and Causes

What are the symptoms of a spider bite?

Spider bite symptoms vary depending on the type of spider.

Black widow spider bites cause an immediate, sharp, pinprick-like pain. The bite area then becomes numb. Other signs of a black widow spider bite include:

Bites from brown recluse spiders aren’t immediately painful or noticeable. Instead, you might feel pain an hour after the bite. Other signs of a brown recluse spider bite include:

  • A blister surrounded by a bruise or reddish skin color (similar to a bull’s-eye). The blister may rupture and form a skin ulcer that later scars.
  • Itchy skin in the bite area or all over the body.

Hobo spider bites rarely cause pain. Signs of a hobo spider bite include:

  • Severe headache within minutes or hours after the bite. This headache may last for a week.
  • Hardened skin in the bite area within 30 minutes of the bite.
  • Red, swollen skin.
  • Blisters that produce pus.
  • Fatigue.
  • Nausea.
  • Cognitive impairment (memory problems).

Diagnosis and Tests

How is a spider bite diagnosed?

Seeing the spider is the best way to confirm both a bite and the type of spider. Otherwise, there isn’t a way to test for a spider bite or determine what bit you.

Your healthcare provider may make a diagnosis based on symptoms. Your provider may also send a sample of fluid from a blister to a lab to check for skin infections that cause similar symptoms, such as methicillin-resistant staphylococcus aureus (MRSA).

Management and Treatment

What are the complications of a spider bite?

Some brown recluse bites cause a skin ulcer (wound). If the wound doesn’t heal, you might need surgery.

Black widow bites are the most serious. Children under 16 and people older than 60 may need hospitalization to treat:

How is a spider bite managed or treated?

Spider bite treatments vary depending on symptoms. Treatment for black widow spider bites includes muscle relaxers, sedatives and pain medicines.

Treatment for brown recluse and hobo spider bites include:

  • Daily cleaning with a povidone-iodine solution to prevent infection.
  • Soaking the bite area in sterile saltwater (saline) solution three times a day.

What should I do if a spider bites me?

You should never attempt to suck out or remove venom from a spider bite. Instead, follow these steps:

  1. Clean the bite area with warm water and soap.
  2. Apply a cold, damp washcloth or an ice pack to the bite area.
  3. Elevate the bite area.
  4. Take an antihistamine (allergy medicine) to ease itching and swelling.
  5. Take an over-the-counter pain reliever for pain and swelling.
  6. Seek immediate medical attention for severe symptoms.

Prevention

How can I protect myself from spider bites?

To protect yourself and your family from spider bites:

  • Apply insect repellant that’s registered with the Environmental Protection Agency (EPA).
  • Keep firewood outside and check it for spiders before bringing it into the house.
  • Shake your shoes, hats and gloves to check for spiders before putting them on.
  • Treat clothing and shoes with permethrin, an insecticide.
  • Wear gloves when carrying wood, working in the garden, moving rocks or in other outdoor settings.
  • Wear long sleeves and pants in wooded areas.

Outlook / Prognosis

What is the prognosis (outlook) for people who have spider bites?

Most people with spider bites experience mild symptoms like pain and swelling. These symptoms gradually go away with at-home care.

You may have more painful and severe symptoms if a black widow, brown recluse or hobo spider bites you. With proper medical care, most people recover from venomous spider bites.

When should I call the doctor?

You should call your healthcare provider if you experience:

  • Difficulty breathing.
  • Heart palpitations, a racing pulse or other heart problems.
  • Nausea and vomiting.
  • Severe muscle pain, cramps, weakness or paralysis.
  • Signs of infection, such as fever or yellow discharge from the bite area.
  • Vision problems or severe headache.

What questions should I ask my doctor?

If you have concerns about a spider bite, you may want to ask your healthcare provider:

  • What is the best treatment for my symptoms?
  • How can I prevent future spider bites?
  • Am I at risk for other problems?
  • Should I look out for signs of complications?

A note from Cleveland Clinic

Spiders get a bad rap, but they provide a helpful service by reducing the number of insects on the planet that could destroy crops and land. Spiders really don’t want to bite you. They only bite when they’re trapped or feel the need to defend themselves. Most spider bites are harmless. Your healthcare provider can offer suggestions for alleviating symptoms at home. You should seek immediate medical attention if a black widow, brown recluse or hobo spider bites you.

Brown Recluse Spider Bite | Cigna

Conditions Basics

What is a brown recluse spider?

Brown recluse, violin, or fiddleback (Loxosceles) spiders are about 0.5 in. (1.3 cm) long with a dark violin-shaped mark on the combined head and midsection (cephalothorax). They are found most often in the south-central part of the United States and live in hot, dry, abandoned areas, such as wood or rock piles.

A brown recluse bite can be serious and may require immediate medical care.

What are the symptoms of a brown recluse spider bite?

Brown recluse spider bites don’t always hurt right away. In fact, you may not know that you have been bitten until other symptoms appear. Symptoms of a brown recluse spider bite include:

  • Reddened skin that may be followed by a blister that forms at the bite site.
  • Mild to intense pain and itching for 2 to 8 hours following the bite.
  • An open sore (ulcer) with a breakdown of tissue (necrosis) that develops a week or more following the bite. This may take months to heal.

Some people have a severe, systemic (whole-body) reaction to brown recluse spider bites, including the rapid destruction of red blood cells and anemia (hemolytic anemia). Signs and symptoms include:

  • Fever and chills.
  • Skin rash all over the body with many tiny, flat purple and red spots.
  • Nausea or vomiting.
  • Joint pain.

What should you do if you think you’ve been bitten by a brown recluse spider?

  • Remain calm.

    Try to stay relaxed.

  • Cool the bitten area.

    Apply a cool, wet cloth to the bite, or cover the bite with a cloth and apply an ice bag.

  • Do not apply a tourniquet.

    A tourniquet may cause more harm than benefit.

  • Identify the spider.

    Try to positively identify the spider, or try to take a picture of it.

A brown recluse bite can be serious and may require immediate medical care if you have severe symptoms throughout your body. Call your doctor if an open sore and necrosis develop. Necrosis is black, dead tissue.

How is it diagnosed?

A brown recluse spider bite is diagnosed through a physical examination and questions about the bite. You should be prepared to describe the spider, where and when the bite took place, and what you were doing at the time. (If you are able to safely capture and transport the spider, bring it with you to show your doctor.) Your doctor will ask what your main symptoms are, when they began, and how they have developed, progressed, or changed since the bite.

How is a brown recluse spider bite treated?

Treatment depends on how severe the bite is. For bites that:

  • Do not develop open sores, treatment includes applying a cold compress, elevating the bite area, and avoiding moving the bite area.
  • Cause an open sore (ulcer) and dead skin (necrosis), treatment includes removing the dead skin from the sore. This may involve follow-up and replacing the dead skin with new skin (skin grafts).

Hyperbaric oxygen therapy may also be used for tissue damage from a spider bite.

Medicines that may be used include:

Medicine to counteract brown recluse spider venom is not available in the United States or Canada.

Brown Recluse Spider Toxicity – StatPearls

Continuing Education Activity

In the United States, Loxosceles reclusa or brown recluse spiders are found mostly in the south, west, and midwest areas. They are usually in dark areas such as under rocks, in the bark of dead trees, attics, basements, cupboards, drawers, boxes, bedsheets, or similar locations. Dermonecrotic arachnidism is the local tissue injury that results from brown recluse spider envenomation, while loxoscelism describes the systemic syndrome caused by envenomation. This activity reviews the pathophysiology and presentation of the brown recluse spider biiteand highlights the role of the interprofessional team in its management.

Objectives:

  • Describe the pathophysiology of a brown recluse spider bite.

  • Review the presentation of a brown recluse spider bite.

  • Outline the treatment and management options available for a brown recluse spider bite.

Introduction

In the United States, Loxosceles
reclusa or brown recluse spiders are found mostly in the south, west, and midwest areas. They are usually in dark areas such as under rocks, in the bark of dead trees, attics, basements, cupboards, drawers, boxes, bedsheets, or similar locations. Dermonecrotic arachnidism is the local tissue injury that results from brown recluse spider envenomation, while loxoscelism describes the systemic syndrome caused by envenomation.[1]

Etiology

In the USA, the venom of the Loxosceles reclusa is the most potent among arachnids and most likely to cause dermonecrotic arachnidism.[2]

Epidemiology

Systemic involvement, while rare, is more likely to occur in children than in adults. There has recently been an increase in reports of brown recluse spider bites even in nonendemic areas. Most of these reports are likely because of other causes of similar appearing skin lesions like methicillin-resistant staph aureus skin infections.[3]

Pathophysiology

Brown recluse spider venom is cytotoxic and hemolytic. It has many enzymes that contribute to the clinical manifestations. Sphingomyelinase D, one of the more well-studied components, has been shown to direct toxin-mediated hemolysis and complement-mediated erythrocyte destruction. It does this by activating the complement system.  Within the venom, there are additional proteases that degrade collagen, fibronectin, fibrinogen, gelatin, elastin basement membranes that on their own may not be able to cause the local reaction seen with brown recluse bites but seem to have a synergistic effect with sphingomyelinase D leading to many of the cutaneous findings. Hyaluronidase, alkaline phosphatase, esterase, and ATPase also seem to have effects leading to the cutaneous manifestations of bites.[4]

Histopathology

To further study the necrotic effects of the brown recluse spider bite, there was a study done with rabbits injected with the venom. Although a small sample size, findings showed inflammatory infiltrates, coagulative necrosis and vasculitis. With all samples, there was a zone of eosinophils referred to as “mummified” coagulative necrosis seen between the epidermal and dermal layers. [5]

History and Physical

Brown recluse spider bites usually occur while indoors and as a defense mechanism as they are crushed or rolled over in bed. Some bites will present with only an urticarial rash. If the bite is more severe, the course usually is as follows.  The initial bite will be painless, but over the subsequent two to eight hours it will become increasingly painful. Systemic symptoms of brown recluse venom can present as malaise, nausea, headache, and myalgias. In children, the systemic reaction is more severe and may also include weakness, fever, joint pain, hemolytic anemia, thrombocytopenia, organ failure, disseminated intravascular coagulation, seizures, and death.

The bite site may initially have two small puncture wounds with surrounding erythema. From there, the center of the bite will become paler as the outer edge becomes red and edematous; this relates to vasospasm which will cause the pain to become more severe. Over the next few days, a blister will form, and the center of the ulcer will turn a blue/violet color with a hard, stellate, sunken center. After this step, skin sloughing can occur, and the wound will eventually heal by secondary intention, but this can take several weeks.

Evaluation

The bite of a brown recluse spider bite is a clinical diagnosis. A diagnosis of a spider bite can be made definitively only if the patient has a lesion that is consistent with a spider bite, or the spider was seen biting the patient, and the spider is caught and identified by an entomologist. 

If the clinician makes a working diagnosis of a brown recluse spider bite, lab testing is unnecessary except if there are systemic complaints, especially in children.[6] In these patients the following laboratory studies are performed;

Often a bite from a presumed arachnid can be mistaken as a bite from the brown recluse spider. Most patients aren’t able to find the spider. A helpful mnemonic to use is NOT RECLUSE,[7] to help exclude the cause of bite from a brown recluse spider. 

  • N (numerous) – only one lesion is usually present in a brown recluse spider bite.  

  • O (occurrence) – A bite usually occurs when disturbing the spider. As the name suggests, they tend to avoid people, hiding in dark spaces like in a box or the attic. 

  • T (timing) – Most bites occur between April and October. 

  • R (red center) – characteristic bites will have a pale central area secondary to the capillary bed destruction causing ischemia.

  • E (elevated) – Usually the bites are flat. If the area is elevated >1 cm, then this is most likely not a brown recluse spider bite.

  • C (chronic)- bites from a brown recluse spider most commonly heal within 3 months. 

  • L (large) – Rarely are these bites >10 cm.  

  • U (Ulcerates too early) – If the bite is from a brown recluse spider, they do not ulcerate until 7-14 days. 

  • S (swollen) – often brown recluse spider bites do not exhibit significant swelling unless they occur on the face or the feet

  • E (exudative) – brown recluse spider bites do not cause exudative lesions

Treatment / Management

Initial treatment should begin with simple first aid. Elevate the extremity above the heart or at least in a neutral position. The activity of sphingomyelinase D is temperature dependent so an ice pack to the area should help halt the necrosis process.[8] Clean the wound with soap and water and ensure the patient’s tetanus immunization is up to date. NSAIDs can provide pain management, but some people may need opioids. Antibiotics are only necessary if there is associated cellulitis.

There is scant evidence for the use of dapsone or antivenom.[9] Also, note that dapsone is harmful in patients with G6PD deficiency,[10] and can also cause deadly hypersensitivity reactions.[11]  Steroids may be beneficial as they have been shown to decrease hemolysis and help prevent renal failure. If the infection is severe, consider hyperbaric oxygen therapy and surgical excision after the wound is well demarcated may be a consideration.[2] Early surgical debridement is not advisable.

Management for systemic symptoms is different than for local effects; hospital admission is the recommendation for patients with hemolytic anemia, rhabdomyolysis, disseminated intravascular coagulation or end-stage organ failure.   Treatment of these conditions is not different in this scenario than it would be for any other cause. 

In children, systemic loxoscelism may preclude skin findings and should be considered as a differential in pediatric patients with undifferentiated acute hemolytic anemia especially in regions known to have the brown recluse spider. Hemolysis has been reported up to 7 days after spider bite so adequate follow up instructions should be given to parents of children even if there are no systemic findings during the ED visit.[12] At a minimum, one should obtain a urinalysis at the initial visit if the working diagnosis is a brown recluse spider bite and the patient is being discharged.

Prognosis

Most cases of Brown recluse Spider envenomation manifest only as local soft tissue destruction. Death is rare but has been reported especially in children.[13][14]

Complications

After 4 to 6 weeks of therapy, it may be necessary to proceed with delayed skin grafting.

Deterrence and Patient Education

Most spider bites are harmless. Death from brown recluse spider bites are rare and have been reported only in children.

Identifiable Features: The brown recluse spider may be identifiable by the violin pattern on the cephalothorax which attaches to the legs, although other species may exhibit similar markings. 

Habits; Most bites occur in the summer months. The spiders like to hide in warm, dark corners and crevices like attics, garages, shoes, bed corners. The spiders are usually not aggressive and bite as a defense mechanism when they are being pressed against a surface by the skin of the patient. 

Venom; The brown recluse spider venom is very poisonous but rarely causes a lot of damage because of the small quantity. One of the active enzymes in the venom causes significant damage to blood vessels and cell death to the tissue at the envenomation site. Also, the venom causes the patient’s body to release inflammatory cells like interleukins, cytokines to help deal with the venom but these cells can cause harm to the patient once they activated; this results in red blood cell destruction (hemolysis), platelet destruction (thrombocytopenia), end-organ damage (kidney injury and coma).

Symptoms; Bites are usually painless initially; patients will start to feel a stinging sensation after about 3 hours.  Look out for redness around the site and fang marks. Most commonly, there will be a white blister formation that progresses to scarring and healing over a few weeks. Less commonly, one will see blue discoloration after the blister formation that progresses to necrosis and an ulcer formation. Patients may also experience nausea, vomiting, severe itching, and muscle pain. 

Diagnosis: In the event of a spider bite, the best course is to see a doctor on the same day. If possible, bring the spider as this will help with a definitive diagnosis. Lab tests are not necessary if the patient only has skin complaints but if thee are systemic complaints like fever, headache, muscle pain the doctor may order a complete blood count, electrolyte panel, check coagulation studies, kidney function and urinalysis. 

Treatment: Before presenting to the ED, the following are steps to take:

  • Clean the bite site with soap and water 

  • Elevate the area above the level of the heart 

  • Apply ice to the area 

  • Treat pain with acetaminophen

Additional treatment options include; tetanus immunization, antihistamines for itching, antibiotics if there are signs of infection, escalation of pain medications. There are no antivenoms available in the US. Some have suggested dapsone and systemic steroids, but there is little to no evidence they work, and these medications can have serious side effects. 

Disposition

  • Daily follow up with a primary care physician to determine the extent of skin damage 

  • Admission for observation and further care if there are systemic findings and or lab abnormalities 

  • If there is skin necrosis, the patient will eventually need to be evaluated by a surgeon

Enhancing Healthcare Team Outcomes

Brown recluse spider bites typically only cause cutaneous findings that are localized but sometimes can progress to systemic injury and, rarely, death. Most of these patients will present to the emergency department where they will encounter an ER nurse and emergency medicine physician or physician assistant. The ER nurse will assist with lab draws and local wound care. If admission to the hospital is deemed unnecessary, the patient will need to be seen by their primary care physician over the next few days to monitor the wound progression. If there is an ulcer formation, the patient will eventually need to be evaluated by a general surgeon. If the patient develops systemic findings or lab abnormalities, it would be prudent to involve the toxicologist in the patient’s care to render their recommendations. In the event of end-organ damage like acute kidney injury, a nephrologist will need to be involved in the patient’s care.

Brown Recluse Spider Bites Are Often Misdiagnosed : Shots

The best way to diagnose a strange skin bump is often to decide what it’s not. So say the researchers who have devised a mnemonic device useful for determining that the lesion or lump isn’t a bite from a brown recluse spider — a diagnosis that can be very common and very false, they say.

Around 40 conditions have been or could be misdiagnosed as a nibble from the brown recluse, including Lyme disease, herpes, antibiotic-resistant staph infection, diabetic ulcers and skin cancer. You wouldn’t want to miss out on treatment for any of those things because the doctor said you had a spider bite. And the brown recluse’s venom can cause serious wounds or kidney failure, so isn’t to be trifled with, either.

The aptly named mnemonic NOT RECLUSE could help limit misdiagnoses and make sure people get the right treatment. It stands for things that would not be a factor if a patient was bitten by a brown recluse, like numerous bites (N), the circumstances where the wound occurred (O), or the time of year it came about (T). Tally two or more NOT RECLUSE symptoms, and the brown recluse explanation should be thrown out, the researchers suggest in their JAMA Dermatology paper.

Brown recluse bites have a reputation for causing pus and rotting flesh, so many people assume they’ve been bitten if they have a nasty wound. But only 10 percent of the bites ever need medical attention. In the most serious cases, skin turns black and starts to die in what’s called skin necrosis. If you know you’ve been bitten for sure, the Centers for Disease Control and Prevention recommends seeking immediate medical attention and to bring the spider with you for identification.

Most typically, though, a bite from the spider looks like a pimple or a small white blister and heals on its own over a month or two. And the spiders, just larger than a penny, won’t bite unless threatened. One woman even trapped over 2,000 of the arachnids in her own house over a six-month span, and no one in her family was ever known to have been bitten.

Many people self-diagnose another skin condition as a brown recluse bite because “it’s a sexy diagnosis,” says Rick Vetter, a retired entomologist of the University of California, Riverside, a brown recluse expert and co-author on the study. “It’s like saying you were bitten by a rattlesnake. It’s dramatic. Bacterial infections? Not so much.” These self-diagnoses even happen outside the brown recluse’s range of Southern and central Midwestern states in the U.S.

Physicians tend to falsely diagnose brown recluse bites, Vetter says, because “it’s a really comfortable scapegoat. People want a diagnosis. Doctors want to give them a diagnosis.” So if physicians can’t figure out the identity of an ambiguous bump, they jump to spider bite.

Vetter worked with two dermatologists on the paper; they hope that physicians will make use of NOT RECLUSE to ensure that patients get the right treatments.

“When we see people with cancer or MRSA who get this false diagnosis,” Vetter says, “it really drives home that you can’t just call everything a recluse bite.”

Eager for the whole mnemonic? Here you go. More than two of these would typically exclude a brown recluse spider bite:

Numerous: More than one injury

Occurrence: Not in a secluded area like a box, closet or attic

Timing: The wound arose sometime between November and March

Red Center: The center of the wound is red

Elevated: The middle of the wound is elevated, not sunken

Chronic: The wound has persisted for more than three months

Large: The injury is more than 10 centimeters wide

Ulcerates Too Early: The injury gets crusty within the first week

Swollen: The wound swells up if it’s below the neck

Exudative: The wound is “wet,” oozing pus or clear fluid

Is this your child’s symptom?

If NOT, try one of these:

Symptoms of a Spider Bite

  • Most spider bites cause local pain, redness and swelling. It’s much like a bee sting reaction.
  • A few spiders (such as the Black Widow) can cause a more severe reaction.
  • Helpful if spider seen on the skin or around the child

Cause of Spider Bite Reactions

  • Most spiders have tiny fangs. They inject venom into the skin.
  • The venom is what causes all the symptoms.

Types of Spider Bites

Black Widow Spider Bite

  • A shiny, jet-black spider with long legs (total size 1 inch or 25 mm).
  • A red (or orange) hourglass-shaped marking on its under-side.
  • Causes immediate local pain and swelling.
  • Sometimes, you can see 2 fang marks at the bite site.
  • Severe muscle cramps (especially stomach cramps) occur within 1 to 6 hours. These last 24 to 48 hours.
  • Rarely causes death. Exception: bitten by several spiders or small child is bitten.
  • Note: many are dry bites because the fangs are small.
  • The brown widow spider is related to the black widow. It is found in southern US.
  • Brown widow spider bites are treated the same as black widow bites.

Brown Recluse Spider Bite

  • A brown spider with long legs (total size ½ inch or 12 mm).
  • A dark violin shaped marking on top of its head.
  • Causes pain at the bite. Blisters form within 4 to 8 hours.
  • The center becomes bluish and depressed (crater-like) over 2 to 3 days.
  • Skin damage may require skin grafting in 10% of cases.
  • Other symptoms such as fever, vomiting, muscle pain can occur. No life-threatening symptoms occur.
  • Brown recluse spiders are hard to identify. If you can, bring the spider along in a jar.

Non-dangerous Spider Bites

  • More than 50 spiders in the U.S. have venom. Their bites cause reactions that are not serious. This includes pain or redness at the bite site.
  • The bites are painful and swollen. This lasts for 1 or 2 days. They can feel and look like a bee sting.
  • Some single, unexplained, tender bites that occur during the night are due to spiders.

Show 10 reviews of 9,033 90,000 What are the different bites of this bladder?

Bites from this bladder can be caused by more than one type of incident.Insect bites, including those from spiders and ticks, can cause this symptom. A person bitten or scratched by a cat or dog may also see a blister at the wound site.

Insect bites can lead to a number of symptoms. Some people see some redness and swelling in the area around the bite. Itching is another common symptom associated with insect bites, and people bitten by mosquitoes can experience this discomfort for several days after being bitten.

A brown recluse spider bite will differ from a mosquito bite. An indication that one of these insects has inflicted a bite is the appearance of a purple blister at the site of the bite. If the insect responsible for the wound is a brown recluse spider, a red ring will appear around the bladder. If at all possible, the spider must be captured so that its identity can be confirmed and the victim can be offered appropriate treatment to determine the cause of the bites that may be caused by the blisters.

Ticks can also cause bites that cover the victim’s skin. People who spend time outdoors in forested areas run the risk of being bitten by these small insects. The initial signs of a tick bite include pain and swelling. A blister may appear in the area for several days after the bite. Swelling and itching can also occur in the area of ​​the bite, and the skin may appear red for several days after the bite.

Interaction with four-legged animals in some cases can lead to injury.If the animal is infected with the bacteria that cause cat scratch disease, it can cause blister bites. If a person was simply scratched by a four-legged animal, it may not be clear that a cat or dog is responsible for a bump that appears on the skin a few days after initial contact. If the lymph nodes near the point of contact become swollen, the person can become infected with cat scratch disease.

Bites that cause blistering or other symptoms that appear more than uncomplicated insect bites should be checked by a physician. If blistering or irritation continues to increase over time, the patient should be examined by a physician.Some people are allergic to insect bites and anyone with breathing problems should see a doctor immediately.

90,000 who can be dangerous while traveling

This summer, many of us will travel to Russia – and it will surely be an unforgettable experience.

Arina Prokofieva

biologist

In this case, it would be good to do without seeking emergency medical help.

We have collected dangerous insects that can greatly spoil the experience of the trip.

How to quickly recognize an insect

To find out the name of a bug, download the Google application (iOS / Android), click on the colored square in the search bar and point the camera at the insect.

As a result, the system will recognize the insect and show its name. See how it works:

Bubble beetle

Latin name. Mylabris quadripunctata.

Special signs. Individuals of bright red, yellow and green colors are more common. The body of an adult beetle is large – about the size of the phalanx of the index finger.

Nitters keep on plants singly or in groups of 2-4 individuals. Source: pavelazarov / Instagram

When can I meet. May – August.

Where can you meet. Distributed in the South and North Caucasian districts, in the Krasnodar Territory and South-West Siberia. They inhabit mainly steppe regions and savannas, they can also be found in deserts and semi-deserts.

What is dangerous. A beetle can fall on a person from a tree or collide with him in flight. The beetle’s blood – its scientific name is “hemolymph” – contains the poison cantharidin. Under stress, the bladder releases small amounts of cantharidin.

The poison can damage the skin: at the point of contact, a burn is formed in the form of a watery bladder. Most often, the hands, neck, face are affected. If the skin has wounds or scratches, the burns will be worse.

If the beetle, and with it cantharidin, gets into food, intoxication may develop.During the first 10 minutes after using cantharidin, burning of the lips, mouth and pharynx begins. Sores may form in the mouth and the tongue may swell. Then nausea, vomiting and diarrhea, accompanied by abdominal pain, are added to this.

How to help the victim. A person who accidentally ate a beetle needs to wash out the stomach: drink a few glasses of water and induce vomiting. If cantharidin comes in contact with your skin, disinfect it with chlorhexidine and be careful not to damage the blisters to avoid contamination and dirt.

How not to get hurt. Do not pick up blister beetles, let alone press with your hands and feet: there is a risk of accidentally coming into contact with the poison.

Scolopendra

Latin name. Scolopendra cingulata.

Special signs. Scolopendra is a large brown centipede and is about 12 centimeters long: about the size of a smartphone or the average palm of a person.

As a rule, during the day, centipedes sleep or hide under stones or in cracks, and at night they go out to hunt insects and small lizards

When can be found. April – August.

Where can you meet. On the eastern coast of the Crimean Peninsula.

What is the danger. Scolopendra is especially dangerous in early spring when its glands are filled with poison. Scolopendra usually avoid meeting a person and bite only if they are picked up. On the pain scale, a bite is equivalent to 10-15 bee stings.

The bites are not only painful, but also provoke general malaise, and the mucus secreted by insects causes burning, itching and irritation of the skin.The bite site swells, the temperature rises sharply to 38-39 degrees, chills and body aches occur. The severity of symptoms depends on the size of the scolopendra and the amount of injected poison, but one bite will not lead to death.

Symptoms last up to two days, then the temperature begins to subside, and the swelling at the site of the bite decreases. Scolopendra bites are the hardest for children and adults with allergies.

How to help the victim. Wash the bite site with soap and water and treat the skin with alcohol antiseptic or hydrogen peroxide to avoid getting any infections under the skin: there could be dirt particles on the scolopendra’s paws.

You can smear the bite site with a wound healing ointment. If the skin is swollen, apply a cold compress to it. OTC antipyretics such as ibuprofen or paracetamol will help relieve pain and bring down the temperature. If an allergic reaction develops – the bitten area swells a lot and hurts – you need to take an antihistamine.

If the discomfort persists for more than two days, consult a doctor.

How not to get hurt. If you notice a scolopendra on your clothes or body, do not make sudden movements, do not shake it off or try to swat it: this will make it angry.It is necessary to restrain the panic and let the scolopendra leave by itself, or gently push it off yourself with a stick raised from the ground.

Check clothes and shoes carefully before putting on. If you are spending the night outdoors, inspect your backpack, tent, and sleeping bag each time you use it.

Asian giant hornet

Latin name. Vespa mandarinia.

Special signs. Can be about half the length of an adult’s index finger.The sting of a giant hornet reaches 6 millimeters. Unlike bees, which leave a sting at the site of the bite, the hornet uses it many times.

Hornets usually use this weapon to attack bee nests to feast on larvae

When found. May – August.

Where can you meet. In the Primorsky Territory, in the south of the Khabarovsk Territory and in the Jewish Autonomous Region.

What is dangerous. The giant hornet venom contains an extremely toxic substance – mandorotoxin.It is most dangerous for those who are allergic to bee or wasp venom: one bite is enough for a lethal outcome.

Severe pain immediately occurs at the site of the lesion. At the point of contact with the sting, a dense white blister of small size appears. A red spot and swelling quickly spreads around. The most dangerous places for a bite are the tongue or neck area. With laryngeal edema, oxygen access to the respiratory tract is blocked – the victim may suffocate.

And the hornet’s body also contains a pheromone that attracts other individuals and makes them act aggressively towards humans.About twenty hornet bites can kill an adult even without an allergy to poison.

How to help the victim. Rinse the bite site with cold clean water and apply an ice pack or cold water to the skin. This will relieve pain and slow the spread of the poison. If the hornet has stung in the wrist or finger, all rings and bracelets must be removed from the hand: it can be very swollen.

The victim should be given water to drink – this will reduce the concentration of the poison in the blood.

If the victim becomes worse or knows that he is allergic, take him to a doctor immediately or call an ambulance.If breathing stops, you need to start doing artificial respiration and continue until there is a doctor nearby.

How not to get hurt. Stay as far as possible from flowering plants, as wasps and hornets can be found near them. Hornets also often fly for sweets, so do not leave drinks and food open.

The only way to escape an attack from a swarm of hornets is to flee to cover: it can be a tent or a car. As a last resort, dive into any body of water.You need to plunge into the water with your head, holding your breath, and periodically emerge to inhale. When emerging, create more spray to scare off the hornets. After a few minutes, the insects will lose interest in you and fly away.

Water Scorpion

Latin name. Nepidae.

Special signs. Actually, it’s a bug. The water scorpion is so named for its external resemblance to a scorpion: its front limbs are like claws, and behind it is a long tail process. The body of a water scorpion is flat, in shape and color similar to a withered leaf. At the back end there is a breathing tube, which can be mistaken for a sting. In reality, the whole danger lies in the front.

In length, water scorpions reach 2 centimeters. They live in stagnant water, lakes or rivers with a very slow flow of water and a large number of algae and reeds.They lead a rather passive lifestyle, sometimes they go down to the depths to hunt

When can be found. During the swimming season.

Where can you meet. Throughout Russia.

What is dangerous. It is very painful to grab the skin. Noticing its prey, the scorpion with a swift maneuver puts out a front pair of legs, similar to jaws, and grabs prey – a person can play this role. The legs of the insect bend at the joint like a jackknife and can cut the skin until it bleeds.

Scorpio lives along the coast, as coastal plants have insect larvae, tadpoles and fish fry that it feeds on. But sometimes he can sink to a depth greater than human growth. If a scorpion injures a person’s arm or leg while swimming, the limb can cramp – and it will be much more difficult to get to the shore.

What to do if bitten. If you are bitten at depth, shout to get people’s attention. If after the bite you have a cramp, then get out of the water as soon as possible.If it is far from the shore, proceed as follows:

  1. Change the position of the body: if you were swimming on your chest, roll over onto your back, and vice versa. This will reduce the stress on the muscles that are cramping.
  2. If there is a cramp in the hand, quickly and forcefully clench your hand into a fist, pressing it towards you, then swing your hand away from you and unclench your fist. Repeat this action several times until the cramp is gone.
  3. If the shin is brought together, try to bend and wrap your hands around the foot, and then pull the toes towards you, straightening the leg.
  4. If your thigh is clenched, wrap your hand around your ankle. Then, forcefully pull your leg back toward your back with your hand.
  5. It is more convenient to perform all these manipulations while lying on the water on your back.
  6. When you get out of the water, treat the bite with chlorhexidine and apply cold to relieve pain and swelling.

How not to get hurt. Avoid entering stagnant water overgrown with reeds. Do not swim alone, or at least swim far from the shore.

Red Forest Ant

Latin name. Formica rufa.

Special signs. Length from 7 to 14 mm, red-brown color.

Red ants live in anthills of various sizes. They can be found almost anywhere in nature

When can they be found. From the second half of May to mid-September.

Where can you meet. In the north of the Krasnoyarsk Territory and in the temperate forests of Northern Eurasia.

What is dangerous. Ants carry pathogenic bacteria that can cause various diseases in humans, such as typhoid fever or cholera.During the bite, the ant releases a small dose of acid, due to which a red spot forms in this place, sometimes a small blister.

The painful sensations do not exceed the pain from a mosquito bite. Itching and irritation of the skin usually resolves in 3-5 days.

How to help the victim. Treat the bite with alcohol or hydrogen peroxide. Ice wrapped in a cloth can be applied to the skin to relieve redness and relieve pain. In pharmacies, you can buy antihistamine ointment, such as “Fenistil” or its analogues.In case of a severe allergic reaction, when swelling and extensive redness of the size of a palm develops around the bite, consult a dermatologist or allergist immediately.

How not to get hurt. Do not leave food or sugary drinks outdoors or in a tent. The ants smell water and sweets and come to dine in large groups.

Check for ants on your feet when walking in the forest or in places where anthills, including underground ones, are found – they look like small holes in sandy soil.Shake insects off of you to prevent them from biting.

Mosquitoes

Latin name. Culicidae.

Special signs. Mosquitoes can look very different, and a large size does not always indicate a danger.

Here is a long-legged mosquito, it does not bite humans and animals at all, but the inhabitants are more afraid of it than there are mosquitoes especially in the evening near open reservoirs, because they need water to reproduce.During the day, in sunny weather, they hardly appear.

When can you meet. Late May – early September.

Where can you meet. Throughout Russia.

What is dangerous. Female mosquitoes need protein to reproduce, so they suck the blood of animals and humans. By piercing the skin, the mosquito inserts the proboscis into the blood vessel and secretes saliva. The proteins in its composition cause an immune response in a person, which is manifested by itching and swelling. Combing the skin after a bite, you can introduce an infection into the wound and provoke the development of an abscess.

Mosquitoes also carry parasitic and infectious diseases: malaria, West Nile fever, eastern equine encephalitis, tularemia. They are not often found on the territory of Russia, but such cases do happen.

How to help the victim . To relieve itching, apply a damp cloth or ice wrapped in a cloth to your skin. If discomfort persists, apply Calamine Zinc Oxide Lotion to your skin.

Medical help is needed if swelling develops after a bite, blisters appear.Give the victim any over-the-counter antihistamine for allergies, and lubricate the bite with an anti-inflammatory cream with a glucocorticosteroid. Anyone sold over the counter without a prescription will do.

How not to get hurt. In nature, especially in the forest, in the shade, cover open areas of the body, use deterrents: sprays, creams, combustible spirals and fumigators.

anti-spider agent, what is the danger, first aid for a bite

Timely correct treatment allows you to completely get rid of the intoxication of the body after a spider bite, rehabilitation after adequate therapy is not required. There are a lot of species of spiders on the globe (up to 40 thousand).But most of the arachnids are not dangerous, as they have fragile fangs that cannot bite through the skin.

Absolutely all spiders are poisonous. With the help of poison, they get their own food, and, if necessary, defend themselves. The venom secreted by the spider’s glands can be hemolytic and neurotoxic (paralyzing the nervous system). Small spiders are often not dangerous, and large individuals with their bite can cause serious trouble.

The karakurt spider and the brown recluse spider are deadly for humans.In our latitudes, karakurt, tarantulas, brown hermits do not live, but if you are going to visit exotic southern countries, you need to know what the consequences of a spider bite can be.

Symptoms after bites of domestic spiders or crosses may manifest as nausea, dizziness, fever, joint aches

What does the bite site of dangerous arthropods look like

The site of a spider bite on human skin can look different. To provide the victim with timely assistance, one should be able to distinguish spider bites from other insect bites.

  1. A tarantula bite at first looks like a spherical spot, then turns into a blister with red edges, after a while the blister bursts and an ulcer appears.
  2. The symptoms of a brown recluse spider bite are similar to a tarantula bite, but they do not appear immediately. A blister with a bluish purple, white and red border appears at the site of the bite. When the blister bursts, an ulcer forms.
  3. Karakurt leaves practically no marks after being bitten.A very small red spot may appear at the site of the bite, which will disappear very quickly.

Consequences after bites of crosses and black domestic spiders disappear on their own within 2-3 days

What does the bite site of non-dangerous spiders look like

In the house, in outbuildings and on the personal plot, you can find spiders of both very small and medium sizes.

Larger individuals, for example, a cross, domestic black spiders, can bite a person, but their bites do not pose a health hazard.

  • The karakurt bite is very dangerous, its symptoms appear after a few hours or within an hour. A person experiences severe pain in the affected area, sweating occurs, anxiety, headache, nausea, dizziness, swelling of the eyelids and extremities appear.General weakness, difficulty breathing, cramps, and abdominal pain are also observed.
  • A tarantula bite is not fatal, and symptoms include general weakness, headache, localized swelling and rash. Death can only be caused by an allergic reaction and anaphylactic shock.
  • Signs of a hermit bite appear on the second day, which is especially dangerous, since the poison has time to spread throughout the body. In the first moments after the bite, the person does not experience pain and discomfort.Then there is severe itching, at the site of the bite, the tumor turns into an ulcer, which is difficult to treat. Necrosis develops on the affected tissues. The general condition of the patient is characterized by typical flu symptoms: joint aches, cough, runny nose, high temperature.

What does the bite of a domestic and poisonous spider look like: symptoms and consequences

Spider bite

Not in all cases, a spider bite poses a danger to human health and life.Possible consequences depend on the type of insect and the individual reactions of the victim’s body to the enzymes that the spider injects during the bite. To reduce the risk of developing severe consequences, it is necessary to know the main rules of first aid and the principles of treatment.

What a spider bite looks like

a spider bite at the beginning
x

a spider bite the next day

Most spider bites have common characteristics such as a small blister (blister) in the middle, swelling and swelling surrounding the bite site, and a large redness in the form of a circle.On the outside of the bite site, the redness is paler. It is important to note that a spider can only bite once, so if you have several bites, it is probably not a spider who has bitten, but someone else, or several spiders have bitten at once. A typical spider bite clears up within a few days and does not require much attention in most cases. However, if the bite site looks different – a large blister appears, bright redness that quickly spreads to the sides, blue discoloration of large areas of the skin – these are serious signs that you need to react to immediately and go urgently to a medical facility.In the photo you can see the differences – what a bite of a safe spider looks like and a bite that is dangerous to health.

Food

Psalmopoeus irminia – arboreal

All individuals are exclusively predators. The main diet consists of small arthropods and vertebrates. The name is due not so much to an attack on birds as to the fact that spiders can make their way into nests and destroy small chicks and eggs there. Trapping nets do not stand, but hunt for prey, attacking it from an ambush.



What to do if bitten by a spider

  1. First of all, don’t panic! Although all spiders look scary, there are only about 12 species of bite that have a serious impact on humans or animals. The two most dangerous are the black widow spider and brown recluses.
  2. Check the wound. After the bite, pay attention to the site of the bite – whether there is redness, swelling and burning pain.There may be abdominal pain, vomiting, headache, fever, dizziness. The most dangerous reactions are shortness of breath and shock. If there is more than just a bite mark, slight redness and pain, you need to call an ambulance or see a doctor.
  3. Spider identification – if possible and safe. Some spider bites require serious treatment, including antitoxins. If you are unable to identify the spider, this will be helpful in determining the appropriate treatment.It will help a lot if you can catch the spider in a jar or box (just don’t forget about safety). Or at least take a photo of him and show the photo to the doctor.

First aid for a spider bite

  1. To reduce blood flow in the affected area, an arm or leg must be fixed with a belt or scarf – as in a fracture. This will prevent the poison from spreading quickly into the bloodstream and spreading through the body.
  2. Wash the bite with soap and water. Regardless of whether the spider is harmless or poisonous, rinse thoroughly as soon as possible.Even an ordinary spider can infect a wound when bitten.
  3. Apply a cold compress or ice to the bite.
  4. Drink plenty of fluids to ensure rapid elimination of the poison through the kidneys.
  5. Take a pain reliever such as analgin or ibuprofen.
  6. As well as an antihistamine that will reduce allergic symptoms – itching, burning, rash.

If you suspect that you have been bitten by a venomous spider, you can apply a tight bandage above the bite if it is on your arm or leg, making sure you do not completely stop circulation.

The goal is to slow the spread of the poison, not stop the blood flow to the limbs. If the bite is on another part of the body, apply cold and urgently go to a medical facility. Hospitalization is required for most of these types of bites.

Types of poisons

All arachnids are naturally equipped with a gland that secretes a poisonous substance. This substance is divided into two types: necrotic poison and neurotoxic. The most common spiders that release neurotoxins to neutralize the victim, paralyzing its central nervous system.

Neurotoxic poison

A type of poison that neutralizes the transmission of signals between neurons, and therefore incapacitates the victim’s nervous system. In rare cases, they lead to respiratory and cardiac arrest. But spiders are creatures whose venom can be of both types, which further increases their danger.

Important! Such poison is endowed with karakurt and black widows.

Dots appear after the bites of these spiders. After half an hour, painful local muscle spasms occur, and then the pain goes to the limbs and spreads throughout the body.The patient develops abdominal pain, heavy sweating, and salivation.

Added to everything is nervous tension, hallucinations, headache, high blood pressure. All this is accompanied by vomiting, fainting, shortness of breath, fear. Preterm labor occurs in pregnant women. People with weak immune systems and young children will experience respiratory arrest and, as a result, death.

Necrotic poison

Necrotic poison causes only local reactions affecting tissues.Penetrating into the blood, the poison destroys the blood cells, due to which the death of epidermal cells occurs. As a rule, spider bites with such poison heal for a very long time, forming purulent wounds of various localization. The patient’s temperature rises, general malaise, fatigue, and drowsiness are observed.



Hermit Spider Bite

One of the four spiders whose bite is dangerous to humans is the hermit spider.The brown recluse is generally non-aggressive and generally bites people as a defense mechanism, usually when a person’s leg or hand gets too close by accident.

  • Bitten by a hornet, symptoms, what to do at home
  • Was bitten by a wasp – what to do at home

Brown5

The brown recluse has a clear picture of a violin on its back in the middle of the body – pictured.

The venom of the hermit spider contains powerful cytotoxins and hemolytic enzymes that destroy red blood cells. Although the bite is usually not painful in the beginning, there is a bee sting-like burning sensation for the first few minutes after the sting. A small white blister may also appear at the site of the bite.

Additional symptoms usually develop two to eight hours after being bitten by a recluse spider. Sometimes it takes up to 12 hours before bite symptoms develop. Signs:

  • severe pain at the site of the bite
  • severe itching
  • nausea
  • vomiting
  • fever
  • muscle pain

Local symptoms

Initially, small signs of redness can be seen at the site of the bite.

hermit spider bite

In most cases, then the skin at the site of the bite hardens, the formation of scar tissue can take several days. More severe local reactions also occur and can cause blistering, discoloration of the skin and necrosis of the skin area.

Treatment

Because the reaction to a hermit spider bite can be sudden and severe, it is necessary to consult a specialist for treatment. A visit to your doctor should not be delayed until symptoms appear, see your doctor as soon as possible.If possible, the spider should be caught and brought to a doctor or emergency room for evaluation.

There are no known antidotes for brown recluse bites, so a doctor may prescribe pain relievers, antihistamines to relieve itching, or recommend ice treatments to relieve pain and swelling.



Cross spider bite

The cross is a harmless little creature that lives quietly, hunting insects that fall into their nets.The sharp poisonous fangs of the spider are primarily a hunting tool and serve to protect it from other spiders. The victim, falling into the trap, is quickly paralyzed by the poison, and then the spider devours it. The spider cross looks quite harmless – it is distinguished by its characteristic cross pattern on the back. The color varies from green to gray, depending on the habitat. The cross is very common – it lives almost everywhere.

A human bite can only be accidental. Their teeth are unable to damage hard skin, but thinner areas of the body are not a problem.Most often, this situation can occur while walking in the forest, picking mushrooms or traveling. The crosses grow rapidly and at the end of summer they can grow to impressive sizes.

They stretch webs of cobwebs between trees at the height of a human face. An inattentive mushroom picker falls into the network being laid and completely destroys it. Then the insect, willy-nilly, tries to escape or hides under clothes. At the moment, we can accidentally crush the insect and that’s when the spider bites.

Sometimes such situations occur during sleep. Spiders are nocturnal creatures and often roam in search of good hunting spots. A sleeping person, feeling a slight tingling sensation on his body, instinctively trying to scratch, crushes it, exposing himself to a bite. On the body in the area of ​​the spider bite, erythema or swelling may occur. These symptoms usually go away on their own.

The poison of the cross does not cause any harm to a person. However, people who are allergic and sensitive to spider toxins should see a doctor.



Preventive measures

To prevent the occurrence of bites from various spiders, it is necessary: ​​

  1. Wear shoes and clothing that completely cover the body when carrying out agricultural work.
  2. Do not handle spiders, especially small children.
  3. Do not lie on the grass and try not to sleep in the open-air hayloft where these insects are most common.
  4. Conduct sanitization of premises in time when detecting the localization of poisonous spiders.

A large number of insects are widespread around us, which can cause serious harm to our health with their poison. Therefore, the correct behavior in space plays an important role, especially in the vicinity of such dangerous pests. Be as vigilant as possible when walking with children to avoid unpleasant consequences. After all, the bite of a very poisonous spider can be stronger than a viper or a cobra in its actions.Take care of yourself and your loved ones!



Tarantula bite

A bite of a tarantula (Lycosa, Theraphosidae) is not dangerous to humans, but may be accompanied by pain and swelling. After being bitten, the animal makes a defensive maneuver, shedding hairs from its abdomen. Small hairs, getting into the eyes and on the skin, cause pain and urticaria. A type of tarantula is the tarantula spider.

Tarantula spider bite

There are 400 species of tarantulas of different colors. Cobalt blue to gray or dark brown, sometimes black. The tarantula reaches sizes from 9-10 to 17-23 cm, although its body is not more than 10 cm. The rest falls on the legs. Tarantulas live a very long time – from 25 to 40 years, but this depends on the sex of the spider. He is one of the scariest spiders (outwardly) – his weight is 80 grams! The tarantula spider does not weave a web, like other spiders, but pursues its prey with its long legs and paralyzes it with poison.It feeds on small insects – grasshoppers, beetles, spiders, and even eats small lizards.

Incredibly, the spider has eight eyes – two in the front and two each on the left, right and back! They usually dig holes in the ground and build a house there.

Tarantulas are venomous, but most types of venom are not strong enough to seriously harm someone.

The tarantula bite can be compared to the stings of a wasp or bee. This is harmless in most cases, although a person with an allergy may react like a bee sting.Recently, some have begun to have a tarantula spider as a pet. A human bite can happen through negligence when trying to escape a spider from a terrarium. First aid for a tarantula bite is no different from other bites – a doctor should be consulted if there is an allergy or signs of wound infection.

What to do

Consequences after bites of crosses and black domestic spiders disappear on their own within 2-3 days.Toxins trapped in the body are eliminated without a trace. But in order to reduce discomfort, it is recommended to put cold compresses or ice on the damaged area.

  • What to do with a bite of a karakurt spider, a hermit, a tarantula, everyone who is going to the countries where these arachnids live should know. First aid for their bites should be provided immediately. It consists primarily in immobilizing the injured limb. The leg or arm must be pulled with a tourniquet above the puncture site and given a sublime state.Then call an ambulance.
  • Treatment for arachnid bites depends on the type of venom and symptoms. Serum is administered to victims of karakurt, a brown hermit; in other cases, detoxification is carried out with the help of drip administration of medications (saline solutions and glucose).
  • If the intoxication of the body is accompanied by cardiac, renal failure, then cardiological drugs, respiratory analeptics, glucocorticosteroids are administered. Ulcers with necrotic lesions are freed from necrotic tissues, sanitized and bandaged.

There are a lot of species of spiders on the globe (up to 40 thousand). But most of the arachnids are not dangerous, as they have fragile fangs that cannot bite through the skin

Timely correct treatment allows you to completely get rid of the intoxication of the body after a spider bite, rehabilitation after adequate therapy is not required. But if there is a strong weakening of the body, they strengthen the immune system with vitamin therapy.

The name is due not so much to an attack on birds as to the fact that spiders can make their way into nests and destroy small chicks and eggs there. Trapping nets do not stand, but hunt for prey, attacking it from an ambush.



What to do if bitten by a spider

  1. First of all, don’t panic! Although all spiders look scary, there are only about 12 species of bite that have a serious impact on humans or animals. The two most dangerous are the black widow spider and brown recluses.
  2. Check the wound. After the bite, pay attention to the site of the bite – whether there is redness, swelling and burning pain.There may be abdominal pain, vomiting, headache, fever, dizziness. The most dangerous reactions are shortness of breath and shock. If there is more than just a bite mark, slight redness and pain, you need to call an ambulance or see a doctor.
  3. Spider identification – if possible and safe. Some spider bites require serious treatment, including antitoxins. If you are unable to identify the spider, this will be helpful in determining the appropriate treatment.It will help a lot if you can catch the spider in a jar or box (just don’t forget about safety). Or at least take a photo of him and show the photo to the doctor.

First aid for a spider bite

  1. To reduce blood flow in the affected area, an arm or leg must be fixed with a belt or scarf – as in a fracture. This will prevent the poison from spreading quickly into the bloodstream and spreading through the body.
  2. Wash the bite with soap and water. Regardless of whether the spider is harmless or poisonous, rinse thoroughly as soon as possible.Even an ordinary spider can infect a wound when bitten.
  3. Apply a cold compress or ice to the bite.
  4. Drink plenty of fluids to ensure rapid elimination of the poison through the kidneys.
  5. Take a pain reliever such as analgin or ibuprofen.
  6. As well as an antihistamine that will reduce allergic symptoms – itching, burning, rash.

If you suspect that you have been bitten by a venomous spider, you can apply a tight bandage above the bite if it is on your arm or leg, making sure you do not completely stop circulation.

The goal is to slow the spread of the poison, not stop the blood flow to the limbs. If the bite is on another part of the body, apply cold and urgently go to a medical facility. Hospitalization is required for most of these types of bites.

Types of poisons

All arachnids are naturally equipped with a gland that secretes a poisonous substance. This substance is divided into two types: necrotic poison and neurotoxic. The most common spiders that release neurotoxins to neutralize the victim, paralyzing its central nervous system.

Neurotoxic poison

A type of poison that neutralizes the transmission of signals between neurons, and therefore incapacitates the victim’s nervous system. In rare cases, they lead to respiratory and cardiac arrest. But spiders are creatures whose venom can be of both types, which further increases their danger.

Important! Such poison is endowed with karakurt and black widows.

Dots appear after the bites of these spiders. After half an hour, painful local muscle spasms occur, and then the pain goes to the limbs and spreads throughout the body.The patient develops abdominal pain, heavy sweating, and salivation.

Added to everything is nervous tension, hallucinations, headache, high blood pressure. All this is accompanied by vomiting, fainting, shortness of breath, fear. Preterm labor occurs in pregnant women. People with weak immune systems and young children will experience respiratory arrest and, as a result, death.

Necrotic poison

Necrotic poison causes only local reactions affecting tissues.Penetrating into the blood, the poison destroys the blood cells, due to which the death of epidermal cells occurs. As a rule, spider bites with such poison heal for a very long time, forming purulent wounds of various localization. The patient’s temperature rises, general malaise, fatigue, and drowsiness are observed.



Hermit Spider Bite

One of the four spiders whose bite is dangerous to humans is the hermit spider.The brown recluse is generally non-aggressive and generally bites people as a defense mechanism, usually when a person’s leg or hand gets too close by accident.

The brown recluse has a clear picture of a violin on its back in the middle of the body – pictured.

The venom of the hermit spider contains powerful cytotoxins and hemolytic enzymes that destroy red blood cells. Although the bite is usually not painful in the beginning, there is a bee sting-like burning sensation for the first few minutes after the sting. A small white blister may also appear at the site of the bite.

Additional symptoms usually develop two to eight hours after being bitten by a recluse spider. Sometimes it takes up to 12 hours before bite symptoms develop. Signs:

  • severe pain at the site of the bite
  • severe itching
  • nausea
  • vomiting
  • fever
  • muscle pain

Local symptoms

Initially, small signs of redness can be seen at the site of the bite.

hermit spider bite

In most cases, then the skin at the site of the bite hardens, the formation of scar tissue can take several days. More severe local reactions also occur and can cause blistering, discoloration of the skin and necrosis of the skin area.

Treatment

Because the reaction to a hermit spider bite can be sudden and severe, it is necessary to consult a specialist for treatment. A visit to your doctor should not be delayed until symptoms appear, see your doctor as soon as possible.If possible, the spider should be caught and brought to a doctor or emergency room for evaluation.

There are no known antidotes for brown recluse bites, so a doctor may prescribe pain relievers, antihistamines to relieve itching, or recommend ice treatments to relieve pain and swelling.



Cross spider bite

The cross is a harmless little creature that lives quietly, hunting insects that fall into their nets.The sharp poisonous fangs of the spider are primarily a hunting tool and serve to protect it from other spiders. The victim, falling into the trap, is quickly paralyzed by the poison, and then the spider devours it. The spider cross looks quite harmless – it is distinguished by its characteristic cross pattern on the back. The color varies from green to gray, depending on the habitat. The cross is very common – it lives almost everywhere.

A human bite can only be accidental. Their teeth are unable to damage hard skin, but thinner areas of the body are not a problem.Most often, this situation can occur while walking in the forest, picking mushrooms or traveling. The crosses grow rapidly and at the end of summer they can grow to impressive sizes.

They stretch webs of cobwebs between trees at the height of a human face. An inattentive mushroom picker falls into the network being laid and completely destroys it. Then the insect, willy-nilly, tries to escape or hides under clothes. At the moment, we can accidentally crush the insect and that’s when the spider bites.

Sometimes such situations occur during sleep. Spiders are nocturnal creatures and often roam in search of good hunting spots. A sleeping person, feeling a slight tingling sensation on his body, instinctively trying to scratch, crushes it, exposing himself to a bite. On the body in the area of ​​the spider bite, erythema or swelling may occur. These symptoms usually go away on their own.

The poison of the cross does not cause any harm to a person. However, people who are allergic and sensitive to spider toxins should see a doctor.



Preventive measures

To prevent the occurrence of bites from various spiders, it is necessary: ​​

  1. Wear shoes and clothing that completely cover the body when carrying out agricultural work.
  2. Do not handle spiders, especially small children.
  3. Do not lie on the grass and try not to sleep in the open-air hayloft where these insects are most common.
  4. Conduct sanitization of premises in time when detecting the localization of poisonous spiders.

A large number of insects are widespread around us, which can cause serious harm to our health with their poison. Therefore, the correct behavior in space plays an important role, especially in the vicinity of such dangerous pests. Be as vigilant as possible when walking with children to avoid unpleasant consequences. After all, the bite of a very poisonous spider can be stronger than a viper or a cobra in its actions.Take care of yourself and your loved ones!



Tarantula bite

A bite of a tarantula (Lycosa, Theraphosidae) is not dangerous to humans, but may be accompanied by pain and swelling. After being bitten, the animal makes a defensive maneuver, shedding hairs from its abdomen. Small hairs, getting into the eyes and on the skin, cause pain and urticaria. A type of tarantula is the tarantula spider.

Tarantula spider bite

There are 400 species of tarantulas of different colors. Cobalt blue to gray or dark brown, sometimes black. The tarantula reaches sizes from 9-10 to 17-23 cm, although its body is not more than 10 cm. The rest falls on the legs. Tarantulas live a very long time – from 25 to 40 years, but this depends on the sex of the spider. He is one of the scariest spiders (outwardly) – his weight is 80 grams! The tarantula spider does not weave a web, like other spiders, but pursues its prey with its long legs and paralyzes it with poison.It feeds on small insects – grasshoppers, beetles, spiders, and even eats small lizards.

Incredibly, the spider has eight eyes – two in the front and two each on the left, right and back! They usually dig holes in the ground and build a house there.

Tarantulas are venomous, but most types of venom are not strong enough to seriously harm someone.

The tarantula bite can be compared to the stings of a wasp or bee. This is harmless in most cases, although a person with an allergy may react like a bee sting.Recently, some have begun to have a tarantula spider as a pet. A human bite can happen through negligence when trying to escape a spider from a terrarium. First aid for a tarantula bite is no different from other bites – a doctor should be consulted if there is an allergy or signs of wound infection.

Prevention

Keep insects out of your home because they can be dangerous and attract other animals that feed on them.To prevent animals, you must always close the doors, put mosquito nets on the windows.

The house should be cleaned regularly, you should remove the cobwebs from the cornices, ceilings, behind furniture and other places where insects can settle with a broom. With a strong reproduction of invertebrates, you need to pickle the room with an aerosol insecticide, for example, dichlorvos, raid or any other means.

Karakurt bite

Karakurt (Latrodectus tredecimguttatus) is a poisonous spider that lives in Moldova, Crimea, Central Asia.For humans, females are dangerous, which have a pair of tubular poisonous glands located on the upper jaw. The poisonous segment (chelicera) ends with a movable sharp claw with an opening of the duct of the poisonous gland. The female has a spherical dense black abdomen with reddish spots. The length of the karakurt is about 10 mm.

Symptoms of poisoning with karakurt poison

After the bite, a small, quickly disappearing speck is formed. After 10-20 minutes, severe pain develops at the site of the lesion, which spreads to the abdomen, lower back, chest.Strong mental agitation, headache, dizziness, choking, nausea, vomiting, weakness, shortness of breath, cyanosis, tachycardia, arrhythmia are observed. Severe drooling may begin. Respiratory arrest is possible.

Black widow bite

A spider of the karakurt species of the genus Latrodectus – “Black Widow” (Latrodectus mactans) lives in the United States. The females of this species are very large: their paws reach 5 cm, and the body length is 1.5 cm. On the black back there is a red hourglass pattern.

Males are smaller, with a white mark on the back, the small size of the venomous apparatus and poorly expressed aggressiveness make them practically harmless to humans.When disturbed, they fall to the ground, curl their paws and pretend to be dead. Black widow females are poisonous from the moment they are born. If they guard the laid eggs or feel threatened, they prefer to attack. Spiders use their venom to paralyze prey, from which they then suck hemolymph.

The period of post-copulation passivity of the female allows the male to escape from the female partner if she is not very hungry. If the female is hungry, then after mating she eats the “spouse”, and therefore is called a “widow”.

The poison of karakurt is a protein with a molecular weight of 130,000. Under the action of the poison, ion channels are formed in the presynaptic membranes of nerve cells, through which Ca 2 ++ ions enter the cell. Under the influence of the toxin, exocytosis of synaptic vesicles is facilitated and the release of gamma-aminobutyric acid (GABA), norepinephrine, and acetylcholine is enhanced.

Changes in intracellular homeostasis and an increase in the content of biologically active substances in the blood are reflected in the functional state of the nervous and cardiovascular systems.

In case of poisoning with karakurt poison, clinical manifestations develop within 30 minutes. The victim usually feels the bite and describes it as a “puncture puncture”. In the area of ​​the spider bite, severe pain is noted, erythema and increased local sweating gradually increase.

A bite of a karakurt degree

With a bite of a black widow, three degrees of severity of the disease are distinguished.

  • I degree; moderate pain at the site of the bite, there are no general clinical manifestations of intoxication, all laboratory parameters are normal.
  • II degree: muscle pain in the bitten limb. Spreading pain to the abdomen with a leg bite or to the chest with a bite on the hand. Profuse perspiration at the site of the bite. Vital signs are normal.
  • III degree: generalized muscle pain in the back, chest, abdomen. Strong mental agitation. Headache, dizziness, choking, nausea, vomiting, weakness, shortness of breath, cyanosis, arterial hypertension, tachycardia, arrhythmia. General profuse sweating. Great salivation.Respiratory arrest is possible. In blood tests, an increase in the content of creatine phosphokinase (CPK), leukocytosis, proteinuria is noted. In the absence of treatment, the maximum severity of symptoms lasts for 12 hours, the duration of intoxication is 48-72 hours.

Way of life

Habitats are quite diverse. Some species are inhabitants of tree crowns and bushes, others lead a terrestrial life, where they dig holes in which they spend a lot of time.

The model of behavior depends on age – the young are more often in burrows, and the mature ones prefer to spend more time on the surface of the soil or plants. The cobweb is used to arrange a nest or place of shelter, both on the ground and in the crown, therefore the presence of tube-like formations indicates the presence of animals, which it is better not to touch and bypass.

Spiders are active only when they are hungry, or for this there is a need, for example, in protective measures or finding a sexual partner. Without food, an individual can stay in ambush for a long time and behave aggressively. The well-fed are less active and spend all the time in their shelter.

Scorpion Bite

Scorpion (Centruroides sculpturatus) is a venomous spider widespread in the world. In Russia, it lives in the southern latitudes. A feature of the structure of the scorpion, unlike other arthropods, is the presence of pedipalps with claws, at the end of the abdomen there is a curved sharp sting, where the duct of poisonous glands opens.The most dangerous is the black scorpion, its size is 50-100 mm.

Scorpion venom binds to sodium channels of cell membranes, causing reactivation of neurons. This is accompanied by a lengthening of the neuronal action potential at the synapses of the autonomic nervous system, which leads to an increase in the blood levels of catecholamines, renin and aldosterone.

Symptoms of poisoning from a scorpion bite

The bite causes severe pain that quickly spreads along the nerve trunks.The victim cries out in pain, severe weakness develops, cramps of certain muscle groups occur, blood pressure rises, the body becomes covered with cold, sticky sweat. A urticarial rash appears in the area of ​​the bite. In severe cases, motor excitement develops, arterial hypertension turns into hypotension, tachyarrhythmia, ventricular extrasystoles, vomiting, profuse sweating, priapism, salivation occur.

Increasing visual impairment, ptosis, involuntary contractions of the muscles of the tongue are noted, speech becomes slurred.Within 2-3 hours after the injection of the poison into the body, breathing is disturbed, pulmonary edema develops. Death occurs with the phenomena of increasing acute cardiovascular and respiratory failure.

When assessing the toxicity of arthropod venom, the following was noted:

Treatment of a spider bite

To reduce the spread of venom from the site of the bite through the body, limb immobilization is indicated. The pain is relieved by carrying out novocaine blockade, pain relievers are administered: non-narcotic and narcotic analgesics.Cold is applied to the area of ​​the bite.

Hormones, antihistamines are administered: h2-receptor blockers (promethazine (diprazine), chloropyramine (suprastin), and others. in severe cases, horse immunoglobulin (IgG) is injected. Antitoxin (from horse serum) prevents the poison from binding to presynaptic membranes and remains effective even 46 hours after the bite.

In case of a scorpion bite, Ca-channel blockers, ACE inhibitors are prescribed. Propranolol (anaprilin) ​​effectively and quickly relieves tachyarrhythmia, but does not improve hemodynamic parameters. With respiratory depression, oxygen is supplied, with the development of acute respiratory failure, artificial lung ventilation (ALV) is carried out.
