Common Spider Bite Symptoms: Household, Wolf Spider

While some spider bites cause only redness and itching, others are more dangerous. Here’s how to identify spiders that bite — and what to do if you get bitten.

Medically Reviewed

There are more than 50,000 types of spiders in the world. All spiders have eight legs, no wings, and only two body parts: a thorax and an abdomen. They also all have fangs and enough venom to kill the insects that make up their diet. But only a handful of spiders have fangs and venom that can penetrate human skin — including the brown recluse spider, hobo spider, camel spider, wolf spider, black widow spider, and banana spider. Most spiders are harmless and will bite only if they feel threatened. But depending on the spider and its victim, spider bites can cause anything from mild itching and redness to a reaction that becomes a medical emergency. Here’s detailed info on some common spiders and their bites.

The Brown Recluse Spider

The brown recluse spider gets its name from its habit of living in dark corners inside or outside homes, such as in woodpiles, closets, attics, and basements. This spider is more common in areas that have warm and dry climates, like the south and central areas of the United States. The brown recluse is about a half-inch to an inch long, is light brown in color, and has a violin-shaped mark on its back. The distinctive mark gives the spider these other nicknames: the violin spider or fiddleback spider.

The Brown Recluse Spider Bite

The brown recluse spider’s venom may cause burning pain and itching within several hours after a bite. The actual bite may cause a stinging sensation or not be felt at all. The bite has the appearance of a bull’s-eye, with a central blister that scabs and falls off, leaving a small ulcer. Possible symptoms include body aches and fever. Children may be at risk for an allergic reaction to the venom. To treat a brown recluse spider bite, immediately wash it and apply an ice pack. You can also use an antibiotic ointment to prevent infection. In most cases, symptoms resolve within 48 hours, but the central ulcer may take weeks to heal.

The Black Widow Spider

The black widow spider is about the same size as the brown recluse spider (a half-inch to an inch long) and also likes dark places. This spider is usually found outside in sheds, barns, or woodpiles. The black widow can be identified by her shiny black color and a red or orange hourglass marking on the underside of her abdomen. Only the bite of the female spider is dangerous. Black widows can be found throughout the United States but are most common in warmer and drier areas.

The Black Widow Spider Bite

The victim of a black widow spider’s bite usually feels it right away, and there may be fang marks and swelling. If you are bitten, you should clean and ice the bite. If the spider has injected venom, you may experience muscle aches and cramps that spread from the bite area to the rest of the body. Possible symptoms include nausea, difficulty breathing, and weakness. If someone bitten by a black widow spider experiences muscle cramps, emergency medical care may include blood pressure medication, muscle relaxants, and, in rare cases, antivenin — a biologic product created to counteract the effects of a spider’s venom. Serious reactions are rare, but are most common in children or very elderly people.

The Hobo Spider

The hobo spider is not native to the United States. It arrived in the northwest from Europe and is now common in California, Oregon, Utah, and Washington. The spider is about one-half inch long and has long legs that allow it to move quickly on the ground. Its upper body is brown and its abdomen is grayish with yellow markings. The hobo likes to live in cracks or holes both inside and outside.

The Hobo Spider Bite

The hobo bite resembles the brown recluse bite, with a central blister that scabs and ulcerates, surrounded by a ring of swollen discoloration. Within an hour after the bite, the hobo spider’s venom can cause a numbing sensation and muscle or joint aches. After about three days, a black scab falls off, leaving an open, slow-healing type of wound.

The Wolf Spider

The wolf spider is common all over the United States. It doesn’t weave webs, and it gets its name from its habit of stalking prey like a wolf. The wolf spider is brown or gray in color and can be 3 to 4 inches across. Because some wolf spiders are large and hairy, they are sometimes mistaken for tarantulas. The female may be identified by a white egg sac that she carries with her. This spider prefers to live outdoors on the ground in loose sand or gravel, but it may wander indoors and be spotted running across the floor.

The Wolf Spider Bite

The wolf spider’s bite can cause pain, redness, and swelling. Its large fangs may tear the skin, which can become infected and cause lymph nodes to swell. Treatment of a wolf spider bite includes cleansing and icing. Swelling and pain can last up to 10 days, but medical attention is usually not necessary unless the victim is a small child or someone who is sick or elderly.

The Camel Spider

Camel spiders are sometimes called wind scorpions or sun spiders, but in reality, they are neither scorpions nor spiders. They belong to a group of desert creatures called solpugids, and they have elongated bodies that make them look more like scorpions than spiders. The name, derived from Latin, means “escape from the sun.” In the United States, camel spiders can be found in the deserts of the southwest. They are light brown in color, can be up to 5 inches long, and can run at about 10 miles per hour — often making a screaming sound while doing so.

The Camel Spider Bite

During the Iraq war, soldiers described huge camel spiders that seemed to run at them in a screaming attack mode. In reality these creatures, though scary in appearance, are not dangerous to humans, and if they run at someone, they are probably just seeking shade in the person’s shadow. They do not have any venom and do not bite except in self-defense. A bite is very unlikely and would not be dangerous to a person if it did happen.

The Banana Spider

The banana spider is found in warm regions of the United States from North Carolina through the Gulf states. It lives in woodlands and forests and produces large, intricate orb webs that glow golden in the sun. The female has a long shape that resembles a banana. She can be about three inches long and has yellow spots on her tan cylindrical body and brown and orange tufts on her legs. The male banana spider is an inconspicuous dark brown and less than an inch long.

The Banana Spider Bite

The banana spider is often confused with the Brazilian wandering spider, which is found among bananas shipped to the United States from South America; neither spider is native to North America. Although the Brazilian spider bite can be dangerous, the banana spider bite is not. Banana spiders will bite only if held or pinched. The bite produces mild stinging and redness (similar to a bee sting) that quickly goes away.

Spider Bite vs Mosquito Bite

September 21, 2021

All insect bites are annoying, whether you’re gnawed on by a gnat, stung by a bee, sucked at by a mosquito, or bitten by spider. In order to relieve the discomfort quickly and effectively, it’s helpful to be able to identify the different types of bug bites most frequently found on humans. Here’s how to differentiate between two of the most common (and annoying!) kinds of bug bites, the spider bite vs. mosquito bite.

Spider Bites

The majority of spider bites are harmless to humans. Common spider bite symptoms include itchiness, redness and/or swelling around the bite, rashes around the bite, and/or pain around the bite. Most spider bites go away on their own, however bites from venomous spiders such as black widows or brown recluses can be serious and require medical attention. Symptoms of more serious spider bites include severe pain and swelling, body chills, stomach cramps, joint pain, nausea, and headache.

Mosquito Bites

Like spider bites, mosquito bites appear as a small red bump on the skin. Often, people who get mosquito bites don’t even feel them. When these kinds of bites are noticeable, they usually cause mild symptoms that subside within a day or two, including itchiness, redness, and general irritation.

While mosquitoes don’t carry harmful venom, they can transmit serious mosquito-borne illness such as malaria, West Nile virus, Zika virus, and La Crosse encephalitis. If you’re bitten by a mosquito and begin to feel feverish and achy, or experience extreme pain or soreness around the bite site, it’s a good idea to get checked out by a medical professional.

How to Distinguish Between Spider & Mosquito Bites

Spider bites and mosquito bites both manifest as red bumps on the skin and can look very similar to each other. The majority of the time, the best way to tell the difference between a spider bite vs mosquito bite is to pay attention to how it feels. Typically, mosquito bites are only itchy and uncomfortable, while spider bites tend cause pain.

Some spider bites leave two distinct dots behind, which can also help you identify them. In addition, mosquito bites sometimes look like irregular, misshapen welts, while spider bites tend to be more round. Both types of bites are dry, which means that if they start to ooze puss or some other kind of fluid, it’s a sign that there’s an infection.

Treatment & Prevention Tips

Harmless spider and mosquito bites are easy to treat at home. Both can be soothed with ice to help numb pain and reduce swelling. Applying an over-the-counter antihistamine cream can help minimize a mosquito bite’s itch, as can essential oils such as peppermint, tea tree oil, witch hazel, camphor oil, and lavender oil.

But the best way to minimize bug bites from spiders, mosquitoes, and other pesky pests is to avoid them altogether. The experts at MosquitoNix offer a wide range of effective pest control solutions, including fogging treatments, misting systems, and more.

Danger from spider bites

Most of the existing spiders, which are about 3000 species, are absolutely harmless. Even if they want to bite, their teeth are too weak to pierce human skin. But there are categories of these arthropods that manage not only to pierce the bodily shell, but also to introduce toxic substances into the body. About the varieties of biting parasites, about their “dirty” business and appearance, read below.

Seek medical attention if bitten by the following types of spiders:

brown recluse;

black widow;

hobo spider;

tarantula;

Brazilian wandering (banana) spider.

How to “not get hooked” by poisonous spiders?

It is quite difficult to notice the attack of a spider. After all, he stings not too painfully. Especially if the bite occurs in the summer. That’s when other insects are active, and you may not be able to tell exactly who bit you. Spider bite can be distinguished by the following features:

– swelling;

– red halo around the bite;

– severe damage to the skin;

In case of extreme sensitivity, the following symptoms are observed:

– itching and rash,

– pain in the area of ​​the bite;

– muscle spasms;

– red or purple bubble;

– sweating;

– difficult breathing;

– headache;

– nausea and vomiting

– fever,

– fever

– swollen lymph nodes

– increased pressure

Spider bites take much longer to heal than other insect bites. They damage skin tissue. Therefore, scratching wounds can lead to sepsis.

Consider poisonous spiders in more detail.

Brown recluse

You may not even notice its stings. After all, at first it is almost not noticeable. The bite site will begin to itch, hurt and redden not earlier than after 8 hours. Further, a red ring is formed around the wound, which resembles a target. If you do not see a doctor in time, blisters may form, and then the surrounding tissue will begin to die, and fever, fever, and severe headache will appear.

In addition, spider bites can cause seizures, jaundice, blood in the urine, and sometimes even coma.

There is no vaccine against the attack of this parasite, so you need to be very careful, and in case of a bite, consult a doctor. He will prescribe a course of antibiotics, and in the most advanced cases, you will have to go to the hospital.

Black Widow

This “lady” has a bright and attractive appearance. She is a shiny brunette with a red hourglass mark on her back. The spider loves loneliness and lives in warm places. Such as fallen leaves, firewood, boxes in the attic. Only the female has poisonous properties. Her bite is not painful, but with a whole train of negative consequences. First, two small punctures appear on the body. Then uncontrolled muscle spasm begins, pain and burning at the puncture site. After some time, the victim will feel the following symptoms:

headache;

pressure increase;

· sweating and salivation;

nausea and vomiting

numbness of extremities;

fear and anxiety.

Fortunately, there is a cure for such a poison, so you should immediately seek medical help.

Brazilian wandering spider

These parasites love warmth. Consequently, due to climate change and the active movement of people and goods between continents, new areas are being captured. They live behind furniture, under skirting boards and in closets. They have long legs and move quickly. At first, the bite of a tramp is imperceptible, but after 15 minutes you will feel all its “charms”. Namely:

– pain and tissue necrosis

– redness;

– discharge of black liquid from a wound;

– hearing impairment

– weakness in the joints;

– nausea and sweating.

Tramp bites heal very slowly. The treatment is the same as for the bite of a recluse spider. Corticosteroid creams, antibiotics, or surgery are indicated. But for the past 15 years, vagrant bites have not been considered dangerous. Most often, the victim will feel nothing but redness, slight swelling, and pain.

Tarantula

The appearance of this spider is rather peculiar. It is massive, with a mouth apparatus in the form of noticeable sharp plates resembling fangs, with which it digs into the body of the victim. The animal has a bright hairline. Lives in the open. It hides under rocks, in tree trunks and in burrows. Unlike its relatives, it is not at all aggressive. It only bites on close contact. The bite is painful but not fatal. Immediately after the attack, the following symptoms will appear:

rash,

edema

pruritus

palpitations;

difficult breathing;

low blood pressure.

Treatment can be easy without antibiotics, but medical attention is still needed.

Brazilian wandering (wandering or banana) spider

Considered one of the most poisonous spiders in the world. And although it is Brazilian, it is already found in Ukraine. Moves quickly, behaves aggressively. Its bite is extremely painful. Immediately after it, severe sweating and salivation occur. The skin swells, reddens and becomes hot. If you do not immediately seek medical help and do not administer an antidote, an encounter with a “predator” can end in sudden death.

Spider Bite Prevention

If you have started a general cleaning with a potential entry into an area where spiders live, the following precautions must be observed:

1. Wear as close clothing as possible;

2. If you’re working in the woods, in the attic, doing cosmetic repairs, put on a hat and a long-sleeved shirt. Be sure to tuck your pants into your socks.

3. Shake out work gloves, shoes and clothes that you haven’t worn in a while, as spiders can hide in them.

4. Do not keep stones, lumber or firewood in the house

5. Do not push the bed against the wall and do not put things in it.

Treatment of spider bites

Treatment depends on the type of spider and the reaction to the bite. But in any case, the following steps should be taken:

1. Wash the affected area with soap and water and apply an antibiotic cream;

2. Apply an ice pack to the bite and change it every 10 minutes

3. If the spider has bitten on the arm or leg, lift the limb up;

4. Take pain medication;

5. Seek medical attention immediately if you feel unwell after being bitten;

6. Show the specialist the parasite that bit you, even if the attacker is already dead.

Insects and arachnids can pose a threat to people with allergies, biologist Pavel Glazkov told “Gazeta.Ru” . He warned that their bite could cause dangerous consequences for their health, in particular, suffocation and Quincke’s edema.

“Moreover, there are cases when there is no allergy to the bite of one insect, and a person cannot tolerate the poison of another, since the substance has a different composition [from other poisons],” the expert noted.

According to him, a serious reaction can be provoked by an ant or viper sting, even fatal cases are known due to an allergy that has developed to snake venom. However, if the victim is promptly provided with medical assistance, a detrimental effect on health can be avoided.
