And here’s when you should see a doctor.
When it comes to spider bites, there’s literally one person ever for whom it’s been a great experience (what up, Spiderman?). and he’s fictional.
For the rest of us non-superheroes, getting bit by an eight-legged critter is something we’ll do anything to avoid. And with good reason: At best, getting bitten by a spider is an icky, slightly painful experience. But, at worst, it can be a life-threatening nightmare.
The good news: Out of the 3,000 or so types of spiders in the U.S., only a handful are known to bite, and of those, only about three are venomous and poisonous spiders and can put your life at risk, according to research published in American Family Physician. And if you’re wondering how long spider bites take to heal? While certainly itchy and annoying, most bites heal up within a week (other than brown recluse and hobo spider bites, which can unfortunately take weeks or much longer to heal, depending on whether you develop an infection).
But if you don’t happen to be a spider expert, how do you know if your spider bite is cause for serious concern—or how to make the itching and burning stop? The Instagram photos below (all reviewed by experts) will give you an idea of what different types of spider bites look like—and what you should do if you spot one on your bod.

Sometimes, spiders leave behind two distinct puncture holes right next to each other—but unless you actually see the spider do the dirty deed, it’s hard to know if it was caused by an arachnid or some other biting bug.
In fact, the vast majority of «spider bites» are actually bites from other insects like fleas, ticks, and mosquitoes; are a rash from an allergic reaction; or are skin abscesses from an infection, says Justin Arnold, D.O., assistant professor of emergency medicine at the University of Alabama at Birmingham, and the associate medical director of the Alabama Regional Poison Control Center at Children’s of Alabama.
The symptoms are often similar, too—pain, swelling, itching, and redness—so it’s an easy mistake to make. In fact, even spider experts and medical professionals have a hard time differentiating bug bites from spider bites just from how they look, he adds.
«Many people don’t recall an injury or specific bite and hold a common belief that a spider must have bitten them without them knowing,» he says. «In a majority of the cases that we see, a spider was never seen by patient and is not responsible for their infection.»

While poisonous bites are rare, any bite—spider or otherwise—can turn serious if it becomes infected, says Arnold. There are three main complications that can arise from bites: cellulitis, blisters, and swelling, says Arnold.
When a spider bite turns into cellulitis—a common (although painful) skin infection—a rash begins to spread around the wound, and the skin becomes painful and hot to the touch.
Another common reaction to many spider bites is to get «weeping» blisters at the site (they look puffy and fluid-filled). Small blisters on their own, with no other symptoms, don’t necessarily need special care. But if a blister opens, it becomes at risk for infection, says Arnold, so don’t try to pop them! If you think you may have an infection at the bite site, whether from cellulitis or open blisters, it’s best to have your doctor take a look.
Swelling is another very common symptom of insect or spider bites. Even though the swelling can get quite pronounced it’s not necessarily a problem, as long as it goes down within a few days. But if the swelling doesn’t go down, gets significantly worse, or is accompanied by other symptoms, it’s time to get medical attention, says Arnold.

The two most common spider bites are from house spiders, specifically the jumping spider and the wolf spider. While it can be scary to be bitten by any spider, these bites normally aren’t any more painful than a bee sting and shouldn’t cause problems beyond some redness, swelling, and itching, Arnold says.
Treat these at home by washing the site with soap and water, using cold compresses, and taking an ibuprofen to reduce pain and swelling, he adds.

Of all of the spiders, black widows pose the greatest health threat to Americans, according to Rick Vetter, Ph.D., a spider expert in the department of entomology at the University of California, Riverside. Their bite is extremely painful and, while an antivenin (a.k.a. anti-venom) exists now, before it was discovered, about 5 percent of bitten people died.
Think you can ID a black widow bite on sight? Not so fast: The actual bite looks a lot like any other spider bite. However, they do tend to become more swollen and red than your general household spider bite, he says.
Black widow spiders are tough to identify, as well. Only female black widows have the characteristic red hourglass-shaped markings on their backs. Male and immature black widows have tan and white stripes, Vetter says.
Because these types of bites are so serious, if you strongly suspect you were bitten by a black widow or you develop muscle cramping, abdominal and chest pain, high blood pressure, a racing heart, and/or vomiting within two hours of a bite, go to the ER immediately, Arnold says.

The brown recluse (also known as the fiddleback spider or violin spider) is one of the most venomous spiders in America, but they are limited to very specific geographic regions—if you don’t live in one of these places, it’s highly unlikely you need to worry about this type of bite, Vetter says. (Check out this map to see if you’re in the danger zone.)
And despite what you may have heard, even where brown recluses are present, they rarely bite, he adds. To identify a brown recluse, look for six eyes arranged in pairs. (Although getting close enough to see the eye pattern on a spider sounds, frankly, terrifying.)
Brown recluse bites do happen though, and when they do, they are often described by «sharp burning pain,» Arnold explains. Within several hours, the bite area becomes discolored and forms an ulcer that can takes several weeks to heal. In addition to the wound, individuals can also develop fevers, muscle aches, and in rare cases, severe anemia as a result of the venom.
Start by treating any bite at home with cold compresses and an antibiotic cream, but if you start to show severe symptoms, including a lot of swelling, increased pain, fever, spreading rash or other sign of infection, get medical attention immediately, he adds. There isn’t an antivenin, but they can treat the symptoms and manage the infection.

The hobo spider is actually a pretty common venomous house spider in the U.S., but despite some scary media reports, they’re not aggressive and will only bite if provoked, according to the U.S. Forest Service. In addition, about half of hobo spider bites are «dry,» meaning they contain no venom, the service adds.
If you do receive a venomous bite, within a few hours it will become red and hard, similar to a mosquito bite, and within a day or two will develop blisters. After the blisters open, a scab typically forms along with a rash that often looks like a target or bull’s eye.
Because these wounds can become necrotic (as in, infected to the point they start killing surrounding tissue) and can last for years in some cases, you should see a doctor immediately, Arnold says. There isn’t an antivenin but they can treat the symptoms and manage any infection with antibiotics.
Hobo spiders can be hard to identify, according to the Forest Service. They are large and often have chevron-type markings on their backs, but these won’t be visible on darker-skinned adult spiders, which is why it’s important to get any bite checked out if it starts to show signs of infection or you see a target forming on your skin, Arnold says.

Tarantulas may look big and scary, but most of the North American varieties are pretty chill. And even while the bite itself can be painful, the venom is fairly benign and likely won’t cause long-term issues, Arnold says. Like most spider bites, tarantula bites can cause some swelling, itching, and irritation.
However, he adds, tarantulas also have the ability to flick hairs off of their body and into your skin, which can be very irritating and painful. And some people are allergic to tarantula venom, which can make the bite even more inflamed, according to the National Institutes of Medicine.
Most of the time, it’s fine to try treating these at home by washing the site, applying ice, and taking ibuprofen, he says. But if you find yourself having a more extreme reaction, including symptoms like rapid heart rate or difficulty breathing, get to the emergency room.
10 signs you have a spider bite — and what to do if you have one
- There are more than 40,000 different types of spiders in the world.
- Itching, redness, and swelling are among the most common signs of a spider bite.
- Spider bites should be cleaned with warm water and mild soap promptly to avoid infection.
- In the case you’ve been bitten by a poisonous spider, visit the doctor immediately.
Even if you can’t see them, spiders are everywhere. The eight-legged arachnids can survive in almost any habitat and climate. At some point or another, you may encounter one of these creatures in your home or out in the wild. After all, the US National Library of Medicine reports that there are more than 40,000 kinds of spiders worldwide . Although spiders are generally afraid of humans, it’s not uncommon for the web-spinners to bite if they feel threatened.
The severity of your bite wound will vary depending on what type of spider bit you. Some spider bites are harmless, while others not so much. You will likely know right away if you have been bitten by a poisonous spider like a brown recluse spider or the infamous black widow spider. The bite and the surrounding area will be painful and will continue to feel worse with time.
This is just one of the signs of a poisonous spider bite. If you’ve been bitten by a spider and are experiencing breathing issues, stomach cramps, or pain, seek medical help right away, according to the Mayo Clinic . You should always get medical attention if you think you have a poisonous spider caused the bite.
But, for the most part, you won’t need to take a trip to the doctor for your spider bite unless you have any of the below symptoms. If you have a spider bite that’s not so bad, make sure to clean it out with warm water and mild soap. Once it’s been washed out, put a dab or two of antibiotic ointment on the bite and it should clear up within a few days. The Mayo Clinic also recommends elevating the area of your body where the bite is.
Here are the 10 signs of a spider bite.
You have pain near the bite.
This is one of the top signs that you have a poisonous spider bite. Pain from a black widow spider bite usually shows up about 60 minutes after the initial bite. The pain can make its way from the wound to your abdomen, back, or chest, according to the Mayo Clinic . A brown recluse spider bite will also bring about pain, but it’s a gradual process that usually takes about eight hours to rear its horns. Not all pain is harmful, though. A wolf spider bite will cause pain but is not toxic.
Over-the-counter pain relieving medications like ibuprofen and acetaminophen can also bring relief, according to the Mayo Clinic . Talk to your doctor before treating the wound.
You can’t stop sweating.
Profuse and heavy sweating can be a sign of a poisonous spider bite. Sweating occurs when the venom from the bite starts to impact the nervous system. One study conducted by researchers in Albania found that 56.9% of people with a spider bite experienced sweating. In some patients, sweating started within 30 minutes after the bite where in others it was 60 minutes or more.
You can’t stop itching a certain area of your body.
Tarantulas may look scary, but the hairy spiders are not poisonous. Tarantula bites, however, can cause an allergic reaction, according to US News & World Report . As a result, the bite and surrounding area may become itchy. This is a common sign of a spider bite.
A rash starts to develop.
A study published in the Journal of the American Board of Family Medicine found that a bite from poisonous brown recluse spider can cause a rash or ulcer to form in the bite spot. This is not true of all spider bites, but if you notice this symptom, visit a doctor right away.
You feel hot or have the chills.
If you have a spider bite and don’t treat it fast, it may trigger a fever or chills. A rise in your body temperature can mean that you were bitten by a poisonous spider. A spider’s venom can destroy the tissue in the area of the bite and trigger your body into a fever, according to Healthline . Chills occur when the body starts to fight off an infection.
You are experiencing swelling
Venom from a spider can cause the bite to swell. This is a common sign of a spider bite, especially if you are also experiencing pain and redness. You should place ice or a wet compress on the impacted area to help reduce the amount of swelling, according to the US National Library of Medicine .
You develop a blister.
Most spiders in the US won’t typically cause blisters as the result of a bite, but brown recluse spiders will. To treat the infection, clean the blister and surrounding area with warm water and mild soap. Apply an antibiotic cream. This will help fight against infection. Make an appointment to see your doctor, especially if you notice the blister and surrounding area starting to turn blue, purple or black, according to WebMD .
Your muscles feel achy and are cramping.
Muscle spasms and cramps can occur if you have been bitten by a poisonous spider, like the black widow spider, according to MedBroadcast. The venom can also cause your muscles to ache. This usually begins in the area of the bite and occurs in 30 to 60 minutes after the bite.
You feel queasy.
Black widow and brown recluse spider bites can cause nausea or vomiting in some people, according to the University of Pittsburgh Medical Center . This reaction will not usually happen if you were bitten by a non-poisonous spider.
You experience more severe symptoms like seizures, blood in your urine, and jaundice.
Other severe spider bite reactions can include kidney failure and can cause you to fall into a coma, according to the University of Pittsburgh Medical Center . This is why it is important to seek medical help right away if you think you may have been bitten by a poisonous spider, like a brown recluse or black widow spider.

Black widow spider bite symptoms are immediate pain, burning, redness, and swelling. Other signs and symptoms of a black widow spider bite are a feeling of a pinprick, and sometimes double fang marks on the person where the spider bit. Often, a person does not know that a black widow spider has bitten them.
Symptoms of a brown recluse spider bite are a mild sting followed by severe pain and local redness that usually develops within eight hours or more after the bite. Some brown recluse spider bites may include a purple or blue area around the bite, which is surrounded by a whitish ring and a large outer ring in a bull’s eye pattern. A fluid blister then forms at the spider bite site, and then sloughs off revealing a deep ulcer that may turn black. Other signs and symptoms of a black widow or brown recluse spider bite may include abdominal or joint pain, fever, nausea, and headache.

What are the signs and symptoms of a brown recluse spider bite (pictures)?
The bite of a brown recluse spider leads to a mild stinging, followed by local redness and severe pain that usually develops within eight hours but may occur later. Some reports of brown recluse bites describe a blue or purple area around the bite, surrounded by a whitish ring and large red outer ring in a «bull’s eye» pattern. A fluid-filled blister forms at the site and then sloughs off to reveal a deep ulcer that may turn black.
Can black widow or brown recluse spider bite symptoms be the same?
Generalized symptoms of bites from black widow and brown recluse spiders may include:
- Abdominal pain
- Joint pain or stiffness
- Feelings of malaise
- Muscle tension or cramping
Rarely, black widow spider bites are fatal; however, a few individuals have died from brown recluse spider bites, which are more common in children than in adults.
If a spider was not observed inflicting the bite, it is difficult if not impossible to determine whether a spider bite occurred, since many conditions of the skin may produce the same symptoms as a spider bite. Streptococcal and Staphylococcal infections, early lesions of herpes simplex or zoster, burns, stings or bites from other arthropods or insects (including fleas, bedbugs, mosquitos, biting flies, ants, and ticks), thorn injury, and early Lyme disease all may be characterized by skin findings similar to those from a spider bite.
Spiders rarely bite people, and only if threatened. People often thing they have spider bites when the irritation is from another cause.

Are spider bites dangerous?
Most spiders do not have mouth parts strong enough to penetrate human skin, and the majority of spiders found in the U.S. and are actually harmless. There are two notable exceptions, the black widow spider and the brown recluse spider, which are both dangerous to humans. Spider bites are fortunately uncommon. In many cases, presumed spider bites are actually due to another skin condition or an insect sting.
The black widow and brown recluse spiders are more common in the southern states of the U.S. They prefer warm, dry climates and undisturbed areas such as basements, closets, woodpiles, attics, or under sinks. The black widow spider is a small, black, shiny spider with a red hourglass marking on its belly. The brown recluse spider is sometimes termed a «violin spider.» It is about an inch long and has a marking resembling a violin on the upper part of its back. Bites from both the black widow and brown recluse spiders are dangerous to humans and require prompt emergency medical care.
