The facts about Spider Bites.

Overview

Venomous spiders found in the United States include the black widow, brown recluse, and hobo spiders. They can be dangerous to outdoor workers including farmers, foresters, landscapers, groundskeepers, gardeners, painters, roofers, pavers, construction workers, laborers, mechanics, and any other worker who spends time outside. These spiders occasionally find their way inside structures or buildings and can also present a risk to indoor workers including machine operators, janitors, and cashiers. Spiders are usually not aggressive and most bites occur because a spider is trapped or unintentionally contacted. It is important for employers to educate their workers about their risk of exposure to venomous spiders, how they can prevent and protect themselves from spider bites, and what they should do if they are bitten.

Types of Venomous Spiders

Black Widows

Black widow spiders are found throughout North America, but are most common in the southern and western areas of the United States. They are identified by the pattern of red coloration on the underside of their abdomen. They are usually found in workplaces containing undisturbed areas such as woodpiles, under eaves, fences, and other areas where debris has accumulated. They may also be found living in outdoor toilets where flies are plentiful.

Black widow spiders build webs between objects, and bites usually occur when humans come into direct contact with these webs. A bite from a black widow can be distinguished from other insect bites by the two puncture marks it makes in the skin. The venom is a neurotoxin that produces pain at the bite area and then spreads to the chest, abdomen, or the entire body.

Brown Recluse Spiders

The brown recluse spider, also known as the violin spider, is most commonly found in the Midwestern and southern states of the United States. It is brown in color with a characteristic dark violin-shaped (or fiddle-shaped) marking on its head and has six equal-sized eyes (most spiders have eight eyes). Brown recluse spiders are usually found in workplaces with secluded, dry, sheltered areas such as underneath structures logs, or in piles of rocks or leaves. If a brown recluse spider wanders indoors, they may be found in dark closets, shoes, or attics.

The brown recluse spider cannot bite humans without some form of counter pressure, for example, through unintentional contact that traps the spider against the skin. Bites may cause a stinging sensation with localized pain. A small white blister usually develops at the site of the bite. The venom of a brown recluse can cause a severe lesion by destroying skin tissue (skin necrosis). This skin lesion will require professional medical attention.

Hobo Spiders

The hobo spider is found throughout the Pacific Northwest. It is large and brown with a distinct pattern of yellow markings on its abdomen. Unlike many other similar looking spiders, hobo spiders do not have dark bands on their legs. To catch their prey, hobo spiders build funnel webs in holes, cracks, and recesses. They may be found in outdoor workplaces with retaining walls, and in foundations, window wells, and stacks of firewood and bricks. Indoors, they can nest between boxes or other storage items, on window sills, under baseboard heaters or radiators, behind furniture, and in closets. Hobo spiders do not climb like most spiders but are fast runners. These spiders are much more likely to attack if provoked or threatened. The bite of a hobo spider may go unnoticed; however a moderate to severe, slow-healing wound will develop.

Symptoms

Symptoms associated with spider bites can vary from minor to severe. Although extremely rare, death can occur in the most severe cases. Possible symptoms resulting from a spider bite include the following:

  • Itching or rash
  • Pain radiating from the site of the bite
  • Muscle pain or cramping
  • Reddish to purplish color or blister
  • Increased sweating
  • Difficulty breathing
  • Headache
  • Nausea and vomiting
  • Fever
  • Chills
  • Anxiety or restlessness
  • High blood pressure

Recommendations for Protecting Workers

Employers should protect their workers from spider bites by training them on:

  • Their risk of exposure to spiders
  • How to identify spiders
  • How to prevent exposure to spiders
  • What they should do if they are bitten by a spider
Prevention

Workers can take the following preventive steps:

  • Inspect or shake out any clothing, shoes, towels, or equipment before use.
  • Wear protective clothing such as a long-sleeved shirt and long pants, hat, gloves, and boots when handling stacked or undisturbed piles of materials.
  • Minimize the empty spaces between stacked materials.
  • Remove and reduce debris and rubble from around the outdoor work areas.
  • Trim or eliminate tall grasses from around outdoor work areas.
  • Store apparel and outdoor equipment in tightly closed plastic bags.
  • Keep your tetanus boosters up-to-date (every 10 years). Spider bites can become infected with tetanus spores.
First Aid

Workers should take the following steps if they are bitten by a spider:

  • Stay calm. Identify the type of spider if it is possible to do so safely. Identification will aid in medical treatment.
  • Wash the bite area with soap and water.
  • Apply a cloth dampened with cold water or filled with ice to the bite area to reduce swelling.
  • Elevate bite area if possible.
  • Do not attempt to remove venom.
  • Notify your supervisor.
  • Immediately seek professional medical attention.

Brown Recluse and Black Widow Spider Bites in Children

Not what you’re looking for?

What are spider bites in children?

All spiders in the U.S. are
poisonous. The fangs of most spiders are too short or too fragile to break through
human
skin. Or their poison (venom) is too weak to cause damage. Most spider bites cause
only
minor, local reactions. But some spider bites can be deadly.

What causes spider bites in children?

In the U.S., 2 spiders can cause serious problems. These are the black widow and the
brown recluse (also called the violin spider).  

Brown recluse spider

The brown recluse spider is about 1 inch (2.54 cm) long. It has a violin shaped mark
on its head. In the U.S., they are more common in the Midwest and South.

They tend to live in undisturbed areas. These include basements, closets, and attics,
or outside under logs or leaf piles. They don’t normally attack, but they will if
they’re trapped.

No deaths have been reported in the U.S. from brown recluse bites.

Black widow spider

A black widow spider is a small, shiny, black button-shaped spider. Female black widows
have red hourglass marks on their underside or abdomen. Males have marks on their
backs.  In the U.S., they are most common in the South and West.

Black widow spiders release a
toxin. This can harm your child’s central nervous system. If your child gets bitten
by a black widow, he or she needs medical help right away.  

What are the symptoms of a spider bite in children?

Brown recluse spider

The following are the most
common symptoms of brown recluse spider bite:

  • Burning, pain, itching, or redness
    at the site on your child’s skin where he or she was bitten. This reaction often
    doesn’t start right away. It may come on several hours or days after the
    bite.
  • A deep blue or purple area around
    the bite. It may be surrounded by a whitish ring and large red outer ring that
    looks like a bull’s-eye.
  • An ulcer or blister that turns
    black
  • Headache and body aches
  • Rash
  • Fever
  • Nausea or vomiting

The symptoms of a brown recluse
spider bite may look like other health problems. Make sure your child sees his or
her
healthcare provider for a diagnosis.

Black widow spider

The following are the most
common symptoms of a black widow spider bite:

  • Immediate pain, burning, swelling,
    and redness at the site on your child’s skin where he or she was bitten. You may
    see double fang marks.
  • Cramping pain and muscle tightness
    in the stomach, chest, shoulders, and back
  • Headache
  • Dizziness
  • Rash and itching
  • Restlessness and anxiety
  • Sweating
  • Swelling and tearing of the
    eyes
  • Nausea or vomiting
  • Increased saliva
  • Weakness, shaking, or not being
    able to move, especially in the legs

The symptoms of a black widow
spider bite may look like other health problems. Make sure your child sees his or
her
healthcare provider for a diagnosis.

How is a spider bite diagnosed in a child?

Your child’s healthcare provider will look at the bite area. He or she will also check
your child for other symptoms of a bite. He or she will also ask if your child was
recently in an area where spiders are often found.

If you can trap the spider without harming your child further or hurting yourself,
try to do so. Put the spider in a glass jar or plastic container. This way, an expert
can identify the spider. This will help your child get the right treatment. 

How is a spider bite treated in a child?

If your child is bitten by a
spider, get medical help right away. You can also do the following right away to treat
it:

  • Stay calm. Tell your child that you can help.
  • Wash the area well with soap and water.
  • Put a cold or ice pack wrapped in a cloth, or a cold, wet washcloth on the area of
    the bite.
  • Apply an antibiotic lotion or cream to the area of the bite. This can reduce your
    child’s risk for an infection.
  • Give acetaminophen to your child. This can help with pain.
  • Raise the site if the bite happened on an arm or leg. This can help prevent swelling.

Treatment will depend on your child’s symptoms, age, and general health. It will also
depend on how severe the condition is.

Brown recluse spider

Depending on the severity of the bite, your child may need surgery. No medicines have
been found to help brown recluse bites. Your child may need to stay in the hospital
for further treatment.

Black widow spider

Your child may need muscle relaxants, pain relievers, and other medicines. Some children
need a special medicine that works against the poison (antivenin). Your child may
need to stay in the hospital for further treatment.

What can I do to prevent spider bites in children?

Children can wear protective clothing when they’re playing where spiders live. These
include long-sleeved shirts and pants. If you can, remove tall grass, leaves, and
logs from outdoor play areas.

You should also keep your child’s tetanus shots up-to-date. Spider bites can get infected
with tetanus.

Key points about spider bites in children

  • Most spider bites cause only minor, local reactions. But some spider bites can be
    deadly.
  • The 2 spiders that can cause serious problems are the black widow and the brown recluse.
  • Venom from the brown recluse spider often causes local tissue damage.
  • Black widow spiders release a toxin. This can harm your child’s central nervous system.
  • If your child is bit by a spider, get
    medical help right away. You can call the poison hotline at 800-222-1222 for advice
    over the phone if your child is stable.

Next steps

Tips to help you get the most from a visit to your child’s healthcare provider:

  • Know the reason for the visit and what you want to happen.
  • Before your visit, write down questions you want answered.
  • At the visit, write down the name of a new diagnosis, and any new medicines, treatments,
    or tests. Also write down any new instructions your provider gives you for your child.
  • Know why a new medicine or treatment is prescribed and how it will help your child.
    Also know what the side effects are.
  • Ask if your child’s condition can be treated in other ways.
  • Know why a test or procedure is recommended and what the results could mean.
  • Know what to expect if your child does not take the medicine or have the test or procedure.
  • If your child has a follow-up appointment, write down the date, time, and purpose
    for that visit.
  • Know how you can contact your child’s provider after office hours. This is important
    if your child becomes ill and you have questions or need advice.

Spider Bites – familydoctor.org

Spiders are found everywhere. But each kind of spider is unique. Some tend to live outdoors. Some are common inside the house. Either way, you may accidently bother a spider—and get bit.

Path to improved health

The majority of spiders in the U.S. aren’t dangerous or poisonous. Most spiders won’t bite you if you don’t bother them. If you do get bit, your symptoms will vary, depending on what type of spider bit you. Generally, your skin may be raised, red, and itchy at the location of the bite. These symptoms may last several days but typically go away on their own.

Most spider bites can be treated at home by following these steps:

  • Wash the bite area with warm, soapy water.
  • Apply an antibiotic cream (one brand name: Neosporin) to help prevent infection.
  • Put ice or a cool washcloth on the bite to help reduce swelling.
  • Take an antihistamine (one brand name: Benadryl) to help with swelling and itching.
  • Take ibuprofen (one brand name: Advil) or acetaminophen (one brand name: Tylenol) for pain.

If you were bit on your arm or leg, raise that area above your heart to help reduce swelling.

However, some spider bites may be more severe. Contact your doctor right away if you have any of the following after being bit:

  • Pain in other parts of your body, including a headache or cramping in your belly
  • Redness that spreads
  • Fluid that leaks from the bite area
  • The bite area looks like a bullseye or turns into an open sore
  • Fever, chills, body aches
  • Nausea and vomiting
  • Pain that keeps getting worse 24 hours after you were bit

Your doctor may prescribe an antibiotic to kill an infection from the bite. They may give you a tetanus shot if you haven’t had one in the past 5 years.

Seek emergency treatment right away if you have any of the following symptoms. They may mean you’re having a severe allergic reaction:

  • Fast heart rate
  • Trouble breathing or swallowing
  • Tightness in your chest
  • Swelling in your mouth or face

Young children and older adults are at higher risk of complications from spider bites. It is more likely they will need to be seen by their family doctor after a possible bite.

If you see the spider that bit you, take it with you to your doctor. It’s okay if it’s dead. Taking it will let your doctor identify the spider and know how to best treat your bite.

Two spiders in the United States have venom that can cause severe skin and health issues. Venom is a fluid that spiders put into their victims when they bite them. This venom is what causes a reaction in your body. The two poisonous spiders that live in the U. S. are the black widow and the brown recluse.

Black widow spiders are mostly found in the southern and western parts of the United States. They are identifiable by their appearance. They have shiny black bodies with a red hourglass shape on their abdomen. They live in dark, quiet places, such as closets, garages, and wood piles.

You may not even notice it if a black widow spider bites you. However, within an hour of the bite, the location of the bite will begin to hurt. You may develop stomach cramps, nausea, and vomiting. The pain may spread to your chest and back. You may sweat more than usual. As time passes, the bite mark will keep getting red and become swollen.

 Brown recluse spiders are most common in the Midwest and southern parts of the United States. They like quiet, dark, indoor places like behind and under furniture, and in closets and basements. They can also be found outside under rocks and other undisturbed places. These spiders are brown and have a violin shape on their back.

You may not feel it if you’re bit by a brown recluse spider. But after a few hours, you’ll begin to feel pain. You may notice a bullseye on your skin where the spider bit you. It may look like a white blister with a red ring around it. As time goes on, the skin in the bullseye may turn purple or blue. You may notice the skin around the bite begins to die. This can lead to an open sore, also called an ulcer. This sore can continue to get bigger for 10 days after the bite. You may have chills, a fever, and body aches.

Things to consider

Prevention is the key to avoiding spider bites. Remember, most spiders only bite when they feel threatened. Be aware of where spiders may live and be careful when in those areas.

  • Spray your clothes and shoes with insect repellent, such as DEET, when you’re going to be outside.
  • Keep firewood and rock piles away from your house.
  • Inspect the outside of your house. Look for any cracks that may allow a spider to get in, then fill any cracks with caulk. Also make sure window screens fit well.
  • Always wear long sleeves, pants, socks, shoes, and gloves when working outside near wood piles or rocks. Also wear these when inside and moving items in a dark location that haven’t been moved for a long time. You may even want to tuck your pants into your socks so spiders can’t climb up the inside of your pant leg.
  • Shake out your shoes and clothes before putting them on in case a spider is hiding in them.
  • Don’t keep anything under your bed.
  • Don’t place your bed right up against the wall. Instead, keep a few inches between the headboard or mattress and the wall.

If you see a spider crawling on your skin, gently flick if off with your finger. If you’re in the house, watch where it lands, then remove it.

Questions for your doctor

  • What kind of spider bit me?
  • How long will it take my spider bite to heal?
  • What kinds of pain medicines can I take for my spider bite?
  • Do I need antibiotics for my spider bite?
  • What can I do to prevent spider bites in the future?
  • How to I wash an ulcer that has formed because of a spider bite?
  • Will my ulcer heal and will my skin grow back?

Topic Overview

What is a black widow spider?

Black widow spiders
( Latrodectus mactans and Latrodectus hesperus) are found throughout the United States, Mexico, and southern Canada. A female black widow is much more likely to deliver more venom than a male spider. Female black widows are long-legged, shiny, coal-black spiders with an orange, red, or yellow shape on their underside that usually looks like an hourglass but may be another shape. Female black widows are usually about 1.5 in. (3.8 cm) long, but they may be smaller.

Black widow spiders are frequently found in low-lying webs in garages, in barbecue grills, around swimming pools, and in wood piles. Most bites occur in rural and suburban areas and occur between the months of April and October. These spiders tend to bite defensively when their webs are disturbed. Bites to babies and children may be more serious than bites to adults.

What are the signs and symptoms of a black widow spider bite?

In most cases of a black widow spider bite, symptoms consist only of:

  • Minimal to sharp pain followed by swelling and redness at the site of the bite.
  • One or two small fang marks like tiny red spots.

In some cases, severe symptoms appear within 30 to 60 minutes. These include:

  • Muscle cramps and spasms that start near the bite and then spread and increase in severity for 6 to 12 hours.
  • Chills, fever, nausea, or vomiting.
  • Sweating.
  • Severe belly, back, or chest pain.
  • Headache.
  • Stupor, restlessness, or shock.
  • Severe high blood pressure.

What should I do if a black widow spider bites me?

If you believe you have been bitten by a black widow spider:

  • Get medical help immediately. Call your doctor, hospital, or poison control center.
  • Remain calm. Too much excitement or movement will increase the flow of venom into the blood.
  • Apply ice to the bite area.
  • Do not apply a tourniquet. It may cause more harm than benefit.
  • Try to positively identify the spider or catch it to confirm its type.

How is a black widow spider bite diagnosed?

A black widow 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. 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 it treated?

Medicine to counteract black widow spider venom (antivenom) is available in the United States, Mexico, and Canada. It is usually used if you have trouble breathing, have high blood pressure, or are pregnant.

Treatment also includes:

  • Medicine for pain and spasms. Pain and spasms may be severe enough to require benzodiazepines, such as lorazepam (Ativan) or diazepam (Valium), or opioids, such as morphine or fentanyl. Calcium may also be used.
  • Antihypertension medicines for high blood pressure.

Spider Bites for Trainers and Supervisors

Objective: Identify general tips to prevent and treat spider bites.

Trainer’s Note

Spiders can be all around landscaping and horticulture work. Spider bites can be a slight nuisance or a serious danger. For this module:

  • Review the information below on spiders, bites, and how to prevent bites.
  • Ask workers to identify symptoms of spider bites.
  • Ask workers to identify areas where they find spiders.
  • Review the important points.
  • Have workers take the True/False test to check their learning.

Background

Many people are afraid of spiders, but the majority of spiders are harmless to humans. In fact, most spiders are beneficial predators that reduce pest populations such as flies, crickets, and mites in and around yards, gardens, and crops. Spiders normally will not attempt to bite unless accidentally trapped against the skin or grasped. However, some actively guard their egg sacs or young. Most spiders prefer warmer climates and dark, dry places where flies are plentiful.

Only a few spiders like the black widow spider and the brown recluse are dangerous to workers. The black widow is known for the red hourglass marking on its underside. Black widow spider webs are usually built in woodpiles, rubble piles, under stones, in hollow stumps, and in rodent burrows.

Brown recluse spiders are very secretive. They can often be found under rocks, in crevices, or inside boxes or containers. Brown recluses are brown in color. They have three pairs of eyes, one pair in the middle and another pair toward each side of their head. They may have a pattern like a violin on their underside — but not always.

Symptoms of Spider Bites

Spider bites can have different symptoms. Most are very mild and need not cause concern:

  • Painless bite, not even noticed.
  • Slight feeling, like a pinprick, when bitten.
  • Slight swelling at the site.

However, other symptoms are more serious:

  • Sharp, stinging sensation when bitten.
  • Significant swelling at the site.
  • Breathing problems.
  • Dizziness, with some nausea.
  • Swelling of the lips or throat.
  • Faintness.
  • Confusion.
  • Rapid heartbeat.
  • Hives.

These serious symptoms call for medical attention—fast. They may indicate a black widow or brown recluse bite, or they may indicate that the worker is allergic to spider bites in general. A cloth dampened with cold water or filled with ice may be applied to the bite while awaiting help.

 

Preventing Spider Bites

  • Shake out clothing and shoes before getting dressed.
  • Check before working near vines, brush, overgrown grass, and wooded habitats.
  • Wear gloves when handling firewood, lumber, and rocks.
  • Install yellow or sodium vapor light bulbs outdoors since these attract fewer insects for spiders to feed upon.
  • Do not stack wood against a building.
  • Remove heavy vegetation and leaf litter around building foundations.

Review These Important Points

  • Black widow spider webs are usually built in woodpiles, rubble piles, under stones, in hollow stumps, and in rodent burrows.
  • Install yellow or sodium vapor light bulbs outdoors since these attract fewer insects for spiders to feed upon.
  • Check before working near vines, brush, overgrown grass, and wooded habitats.

Spider Bites – HealthyChildren.org

​Most spiders are poisonous. They use their poison to paralyze and kill their prey. About 60 species of spiders in North America can bite a human. Fortunately, only a few species can cause significant poisonings. Death rarely occurs. However, bites from the black widow and brown recluse spiders have been known to cause death.

Black Widow Spider

The body of the female black widow is shaped like an hourglass. She is a dark color with red or yellow on the abdomen. Black widow spiders are found in all 48 contiguous states. Only the female is dangerous. The male is too small to bite through human skin.

The bite itself often goes unno¬ticed or may be felt as a pin¬prick. Black widow spider venom is very potent. It attacks the muscles in humans. Symptoms are often severe muscle pain and cramping.

Brown Recluse Spider

The brown recluse spider is also known as the fiddle-back or violin spider. A violin-shaped marking on the back helps to identify it. Both the male and female are dangerous. 

It is rare to see the brown recluse spider when it bites because the bite is painless. Most bites happen while the person is sleeping. Reactions to a bite from a brown recluse vary. They range from mild irritation at the bite site to a potentially fatal poisoning.

What to Look For:  

  • Tiny fang marks
  • Pain 
  • Pain begins as a dull ache at the bite site
  • Pain spreads to the surrounding muscles 
  • Pain moves to the abdomen, back, chest, and legs
  • Blister at the bite site 
  • Mild swelling and a blue-gray mark at the bite surrounded by lightening of skin color 
  • Progressive soft tissue damage; the skin becomes dark blue and then black (necrotic)

First Aid Care for Spider Bites

  1. If you suspect that your child has been bitten by a brown recluse or black widow spider, call EMS. Wash the bite area with soap and rinse with water.
  2. Cover the area with a cloth and apply ice or a cold pack. This will help relieve pain and delay the effects of the venom. (Always protect the skin by wrapping ice or a cold pack in a thin cloth. Direct contact of extreme cold on the skin can cause tissue damage.)
  3. Call the Poison Help hotline (1-800-222-1222).

When bitten by a karakurt, Astrakhan residents need to immediately seek medical help

This year, 14 Astrakhan residents were treated at the acute poisoning department of the Kirov City Clinical Hospital No. 3 after being bitten by a karakurt spider. Despite the fact that today in the arsenal of doctors there is no anti-caracourt serum – it is not produced, hospitals have all the necessary medicines to neutralize the poison. It is only important to seek medical help on time.

The main danger is that the victims do not always immediately notice the karakurt bite, the symptoms of which appear only after a few minutes.These spiders bite does not hurt, but the poison has a neurotoxic effect. There is a sharp pain in the chest, abdomen, lower back. In no case should you hope that the pain will go away on its own. The sooner a person see a doctor, the faster recovery will come.

Timely first aid provided for a karakurt bite is a guarantee of human life and health. Since it is not always possible to quickly deliver the victim to the hospital, you need to remove and neutralize the poison yourself or with the help of another person:

  • in the first 3 minutes after a spider bite, you need to cauterize this place according to the method of P.M. Markovsky – attach two matches to the wound, set the third on fire for a few seconds. You can use a burning cigarette. The high temperature will inactivate the poison;
  • , you can use the method of squeezing the poison out of the wound. To do this, you need to grab the site of the bite into the fold and squeeze out the contents of the wound within five minutes;
  • , the wound should be closed with a dry, clean bandage. It is advisable to immobilize the bitten limb;
  • for severe pain, you need to drink a pain reliever. Persons prone to allergies are advised to take an antihistamine;
  • further specialized treatment – only in a hospital.

The bite of a karakurt spider and its consequences is a serious test for the human body. It is important to know that spiders attack only at the moment when they disturbed their nest or accidentally crushed them. Careful examination of the surrounding area, caution will help to avoid meeting with this poisonous creature.

A man was admitted to the hospital after being bitten by a poisonous hermit spider, and within a few days he developed sepsis and necrosis of the hand

Another incident occurred on the set of Alec Baldwin’s film “Rust”: one of the team members was hospitalized after being bitten by a poisonous spider, according to Sky News.

Illuminator Jason Miller was dismantling the set when he was bitten by a brown recluse spider. Within a few days he developed sepsis and necrosis of the arm and was hospitalized. Jason is in danger of having his arm amputated.

A representative of the film producers declined to provide information, noting that he did not comment on the personal affairs of individual members of the cast and crew.

Currently, a fundraiser is organized on the Internet for the treatment of a member of the film crew.

The bite of a brown recluse spider is dangerous to humans, it leads to significant damage to the skin and, in rare cases, to death. This spider lives in dark, closed places, so it is difficult to spot it right away. This species is most often found in the United States.

Previously, filming of the western “Rust” was suspended indefinitely due to a tragic incident: cameraman Galina Hutchins was killed by a loaded pistol in the hands of Alec Baldwin and director Joel Sousa was seriously injured.The tragedy occurred in late October while filming in Santa Fe County, New Mexico. Baldwin fired a pistol, according to the script, but it turned out that the bullets in the weapon were not fake. The police interviewed eyewitnesses of the incident and Baldwin himself, after questioning the actor was released without charge.

Hollywood demanded to ban firearms on filming

90,000 Spider bite is… What is Spider Bite?

Spider bite causes significant harm to prey. Spider bites are more common in humans and pets due to coexistence.

Spider venom

Neurotoxic poison

Necrotic poison

Spiders with venom causing necrosis are known, these are individuals from the Sicariidae family, which includes Loxosceles and the six-eyed sand spider ( Sicarius hahni ). Spiders from this family possess the dermonecrotic substance sphingomyelinase D , [1] [2] , which is found in only a few pathogenic bacteria. [3] [4] .

Necrotic Bite

Types of spiders whose venom is important for medicine

Brazilian wandering spider (

Phoneutria )

Hexathelidae ( Hadronyche and Atrax )

Hexathelidae , eg Atrax robustus (the only migalomorphic spider with a distant relationship to the araneomorphic spider) is considered one of the most venomous spiders in the world.

Tenet spiders (

Theridiidae )

Only two genera from the snake spider family are of importance in medicine. One of them is black widows, whose bites have caused more deaths than all other spiders. The second is steatodes, but the bites of these spiders are much less dangerous.

Black Widows (

Latrodectus )

Female Latrodectus lilianae

Symptoms caused by a black widow bite are called latrodectism [5] .The venom of these spiders is neurotoxic. [6] Only females bite. The site of the bite is difficult to determine visually, but the pain is comparable to a pin prick. After a while, at the site of the bite, two small red dots appear, mild erythema and edema. There are no necrotic wounds. The poison is yellow, oily, contains α-latrotoxin, which causes the release of acetylcholine, norepinephrine and other mediators from the presynaptic endings, followed by the depletion of their reserves. 30-60 minutes after the spider bite, painful muscle spasms appear, which spread from the bite to the large muscles of the limbs and trunk.Then – a pronounced tension of the muscles of the anterior abdominal wall and excruciating pain (due to such symptoms, a false opinion about peritonitis is possible), however, palpation of the abdomen is painless. In addition, salivation, torrential sweat, vomiting, arterial hypertension, tachycardia, shortness of breath, anxiety, headache, weakness, fasciculations, paresthesias, hyperreflexia, urinary retention, in pregnant women, contractions and premature birth are possible. Rhabdomyolysis and renal failure are rare. As a result of respiratory arrest, hemorrhagic stroke, heart failure, death can occur (more often in young children and debilitated patients).The pain begins to decrease within the first 12 hours, but may worsen again in the following days and weeks.

Steatoda (

Steatoda )

Steatoda capensis

Steatodes, or sometimes they are called – false black widows, outwardly (in size and body shape) resembling black widows, which is not surprising, since they are in the same family. The steatode bite bears little resemblance to the bite of real widows, although the bites of some species have significance in medicine. The bite of a large steatode ( Steatoda grossa ) affects the human body like a very small widow bite.The medical community has given the name steatodism to the symptom of a steatode bite. There are two steatode species in Europe with bite problems ( Steatoda paykulliana and S. nobilis ), and one in New Zealand and South Africa ( S. capensis ).

Use of isolated black widow venom is well used against steatodism. [7] In addition, the developed poison actually has no remission against the Steatode bite, unlike real widows, where 5% of those bitten die even after the administration of antitoxins.

Differs with widows in the presence of a red hourglass-shaped spot on the abdomen (sometimes on the back).

Sicariids (

Sicariidae )

Six-eyed sand spider (

Sicarius hahni )

Loxosceles (

Loxosceles )

Mouse spiders (

Missulena )

Tarantula spiders (

Theraphosidae )

Tarantulas of the New World
Tarantulas of the Old World

Cheiracantium (

Cheiracanthium )

Heteropods (

Heteropoda )

Red-backed jumping spider (

Phidippus johnsoni )

Female Phidippus johnsoni (?) 14 mm

Some people have reported being bitten by the red-backed jumping spider, one of the most common species in the genus Phidippus .Some of the messages came from Colombia, however, they are more widespread and people living elsewhere may stumble upon them as well. Their relatively large size and bright, red color of the back (and females also have a black stripe on the back) make them well visible. The body length of this species is 12 mm.

It is not yet clear how the bites of the red-backed jumping spider occur. In most large spiders, the effect of a bite is not much different from a stinging sting of a wasp or bee.

90,000 What to do if bitten by a spider

Spiders that live in mid-latitudes in nature are usually harmless to humans. You need to be wary of poisonous species that live in warm regions or sometimes become pets.

How to determine which spider has bitten

Each of them has its own characteristics that will help the doctor understand what kind of help is needed.Here are the most dangerous spiders for humans.

Black Widow

This is a small arthropod. The size of 91,135 body together with limbs is about 2.5 cm. The animal is black in color, there is a red hourglass-shaped spot on the abdomen. A poisonous relative of the widow, karakurt, lives in the south of Russia. It also has a black body, but instead there will be red spots of arbitrary shape.

After a bite, there are practically no marks on the skin, only sometimes redness and swelling.But the following symptoms appear :

  • painful muscle spasms for 8 hours;
  • abdominal pain and muscle tension in the abdominal wall;
  • nausea and vomiting;
  • breathing problems;
  • Tremor and sweating.

Tarantula

This is a large spider, up to 10 cm long. The whole is covered with coarse brown hairs.

If he bites a person, there will be signs of an allergic reaction:

  • swelling at the site of the bite;
  • Difficulty breathing
  • itching and rash;
  • swelling of the eyelids, lips and throat;
  • heart palpitations;
  • low blood pressure.

Yellow-sac spider

Found in most of Europe, including Russia. The size of the female is 10–15 mm, and the size of the male is 7.5–12 mm. The spider has a yellow or beige belly with a black stripe. After the bite, severe burning pain appears. The most unpleasant sensations are in the first 5–20 minutes, and after a couple of hours everything usually goes away. Sometimes there is swelling and redness at the site of the wound.

Cross

It is found throughout Europe.The length of the female is 6.5–20 mm, and the length of the male is 5.5–13 mm. It is a brown spider with a cross-shaped spot on its belly.

Sometimes the crosses bite. Edema and redness may occur at the site of the wound. Other symptoms of may appear and persist for up to several weeks:

  • anxiety;
  • nausea;
  • headache;
  • Muscle spasms.

When to see a doctor

You need medical attention if :

  • You know that you have been bitten by a poisonous spider or suspect it.
  • The wound is very painful, enlarged or swollen.
  • Abdominal cramps appear.
  • Difficulty breathing or swallowing.
  • Redness or scarlet streaks in the wound area.

If an infection is suspected at the site of the bite, your doctor will prescribe antibiotics. You may also be offered a tetanus shot. And with the bite of a black widow and the appearance of dangerous signs, they will introduce an antidote.

What to do if there are no dangerous symptoms

Then you can deal with the problem yourself.To do this, :

  • Wash the bite site with soap and water.
  • Apply antibiotic ointment to prevent infection.
  • Apply cool damp cloth or ice to the wound for 10 minutes. Then remove and after 10 minutes repeat the procedure again.
  • If the spider has bitten an arm or leg, raise the limb. This will prevent swelling.
  • Take an over-the-counter pain reliever.

Avoiding a spider bite

They only bite for protection.For example, if a person accidentally hooks on a spider, waves his arms in front of him, or gets into his territory. So it’s best to take action 91,135 so you don’t run into these creatures.

  • Remember how dangerous spiders look and live.
  • When working or cleaning in the basement, garage, attic, wear long sleeves, tuck trousers into socks, and wear gloves and hats.
  • Shake out garden gloves and shoes.
  • Apply repellent to clothing.
  • Install protective screens on windows and doors, seal cracks to prevent spiders from entering the house.
  • Use safe insecticides.
  • Do not leave piles of stones or logs around the house where spiders can live.
  • Do not place the bed close to the wall so that the spider cannot crawl on you at night.
  • Vacuum up arthropods and cobwebs, then shake them into an airtight bag.
  • If you notice a spider on your skin, do not press down on it, just shake it off.
  • Wear gloves, a surgical mask and safety goggles when cleaning the tarantula enclosure.

Attention! Black Widow! / Publications / Balashikha City District

A case of a black widow spider bite was recorded on the territory of the Moscow region. The poison of this type of insect is extremely dangerous, it spreads through the human body in a few minutes and leads to paralysis of the central nervous system.There were no deaths from the bite of a black widow in the Moscow region, but 14 people have already asked for medical help in the Volga region.

The victim of the bite was picking mushrooms on the border of the Moscow and Tver regions. The man felt a sharp pain in the leg area. On the surface of the skin, he found a spider with bright red spots on its abdomen. This is the hallmark of young black widows. Adult insects have a coal-black back. The victim’s life was saved thanks to prompt medical assistance.Also, on the advice of friends, the man burned the bite with a red-hot knife, which prevented the spread of the poison.

You can watch the informational video, as well as get acquainted with the details of this incident, on the website of the “360 Podmoskovye” TV channel.

“Very severe burning pain at the site of the bite, which spreads up the limb. And it is much stronger than from the bite of a viper snake. Then other symptoms develop: chills, severe pain in the whole body, in the abdomen,” the chief toxicologist described the symptoms Moscow Yuri Ostapenko.

When a black widow bites, the most important thing is to call an ambulance as soon as possible. Half an hour of delay can cost your life. The reason why a species of spider, common in arid climates, appeared in the Moscow region is climate change. At the same time, experts believe that the black widow will disappear with the first cold weather.

“One of the main ways of spreading karakurt – their evolutionary tool, is flying on air currents. And since the climate has really become a little warmer, a huge number of unseen animals in the past fall into our middle zone,” said veterinarian Andrey Ermakov.

If you have become an eyewitness of an emergency or yourself have found yourself in a similar situation, urgently contact the unified dispatching service by calling the 24/7 telephone number: 8 (495) 525-6-112, 8 (495) 524-4-112, 8 (915) 059-06-03 or to the service “112” from landline or mobile phones.

to the victim.

Unusual problem

A spider bite is an atypical problem in Ukraine. However, reports of such cases have recently become more frequent – global warming is affecting, which makes dangerous spiders

“Neighborhood” does not mean anything bad, but in our country there are several types of spiders that can cause big trouble.

In addition, Ukrainians are increasingly bitten by exotic representatives of arachnids, such as the tarantula. There are cases when dangerous creatures came to Ukraine with loads of tropical fruits and
attacked base sorters, vendors, or even those unfortunate enough to have an apartment above a grocery store.

How often do spiders bite

Most spiders are completely harmless to humans.There are more than 40 thousand species of spiders in the world, and only 12 out of 500 “biting” species have a strong enough poison to harm humans.

The only spider with deadly poison in Ukraine is karakurt – one of the most dangerous species of spiders from the genus of Black Widows. Karakurt is found in the south of the country, usually these spiders live in
dark secluded places such as woodpiles, basements, manholes, attics, vegetable storage boxes, etc.They only bite when defending if they think they are being attacked.

Bites of karakurt in the Kherson, Nikolaev, Odessa regions are annually reported in the media, but there are few such cases. Although the poison of karakurt is 15% more dangerous than the venom of a rattlesnake, and mortality from a bite
is 4%, many bites result in only minimal symptoms.

According to experts, you will immediately understand if a karakurt bites you. Their venomous bites cause a sharp prick sensation that can develop into dull pain or numbness around the affected area.

internal organs of the victim.

The bite is accompanied by acute pain and redness, at the site of the puncture with chelicerae there are two red dots at a distance of three to 15 mm.
