Dr. Suresh Kumar lives in India and enjoys writing about medical topics.

If you think you may have been bitten by a spider, chances are you are not in serious danger. In most cases, your wound can be treated with basic first aid.1

In fact, if you didn't actually see the spider bite you, that bump, bite, rash, or redness you're experiencing could be due to a wide range of things—including other types of bug bites, pimples, cysts, skin infections, or MRSA.

Even a medical professional may not be certain what bit you unless you happened to catch the offending bug or spider, or unless the bite is producing distinctive symptoms.

Though most spiders are technically poisonous, in the vast majority of cases, their fangs are too small to cause humans much trouble. Typically, the only result of a spider bite is an itchy, red wound that goes away in about a week.

In North America, there are only two medically significant spiders. These are the brown recluse and the black widow.

Symptoms of Black Widow and Brown Recluse Bites

Physical Characteristics
Bite Symptoms
Geographical Location

Warm Southern and Western States

What to Do

According to HealthLine, if you are experiencing any of the symptoms in the above table, you should:2

  • Wash wound with soap and cold water
  • Wrap ice in washcloth and apply to wound for 10 minutes, remove for 10 minutes, and repeat.
  • Go to the ER or get a doctor or a medical professional's help.

If You Can, Take a Photo of What Bit You

When you go to the doctor, you will need to give as much information as possible about the bite, your symptoms, and what you saw bite you (if you saw it). If possible, and if you can do so safely, try to catch the spider or take a photo of it.

First Aid for Other Types of Spider Bites

The vast majority of bites of any kind (spider or not), can be treated with basic first aid:

  • Wash the area with soap and water.
  • Put a cold compress or ice pack on the area (protecting the skin from extreme cold) for about 10 minutes at a time to reduce swelling.
  • If there is itching, you can apply calamine lotion (an anti-histamine), or a paste of baking soda and water several times a day.
  • Elevate the part of your body that is affected by the bite.
  • Over-the-counter pain killers, like acetaminophen (Tylenol), may be necessary to relieve the pain.
  • Keep the wound clean and apply antibiotic ointment.
  • Let any blisters pop on their own.

When to See a Doctor or Get Medical Help

See a doctor if you are experiencing:

  • Hives
  • Fever
  • Abdominal cramps
  • Nausea
  • Vomiting
  • Swelling of face, lips, or throat
  • Breathing problems
  • Shock
  • If the wound gets continually worse or spreads after applying basic first aid

Could It Be a Skin Infection?

Did you see the spider or bug bite you? If not, it's possible that it could be a skin infection. Follow the first aid tips above, and if the problem seems to be getting worse after 2-3 days, you should get professional help.

What NOT to Do When Bitten

  • Do not touch or massage the bitten area. If the spider was venomous, you should leave it alone in order to avoid spreading the venom.
  • Do not engage in any physical activities after being bitten.
  • Avoid heating pads. In the event that the spider emitted necrotic venom, the heat may facilitate the process of necrosis (dead skin tissue).
  • Avoid steroid creams.
  • Sucking out the venom is not recommended.

What a Doctor Will Do

There is no one treatment for all spider bites—it all depends upon the type of spider and severity of the bite. The doctor will begin by evaluating your symptoms. If there are signs of tachycardia, cardiac drugs may be given. Other medications may also be given to treat necrosis (dead skin tissue).

Your doctor may recommend a tetanus booster shot if you haven't had one in the last five years. You may need antibiotics if the bite becomes infected.

Serious cases may require medical evaluation. In some instances, patients may be closely monitored at the hospital.

In rare cases, surgery may be needed, especially if necrosis identified on the spider bite. Surgical evaluation is also necessary if the presenting symptoms are worsening.

More About Brown Recluse Spiders

If you have:

  • A red ring that forms around a white wound that looks like a bullet or a target
  • A blister that has developed on the skin

You may have been bitten by a brown recluse.3 It's possible you won't have felt anything when it bit.

Where They Live

Typically, these spiders live in South Central and Southern U.S. states (including Kansas, Oklahoma, Texas, Louisiana, Arkansas, Missouri, Mississippi, Alabama, and parts of Georgia, Tennessee, Kentucky, Ohio, Indiana, Illinois, Iowa, and Nebraska).

If you don't live in these areas, it's highly unlikely this is what bit you. These spiders also only attack if they are disturbed. They do not aggressively attack humans.

What They Look Like

These spiders are brown, slightly larger than a quarter, and have a distinctive marking on their back that looks like a violin, or fiddle. This can be easily mis-identified however. If you happen to see or catch the spider, the best way to identify it is by looking at its eyes. These spiders only have 6 eyes, instead of the usual 8.

What Happens When They Bite?

People will react differently to the venom. In 90 percent of cases, bites heal without medical attention and will not scar. You will see a small red mark that will heal soon.

For those who are more sensitive, a small blister may appear, the skin may become hard, and it may become blue-grey surrounded by red. It could turn into an open wound. Victims could also experience chills, fever, or headache.

If You've Been Bitten:

  • Wash the area of the bite with soap and water
  • Put a cold compress on for 10 minutes. Remove for 10 minutes, then repeat.
  • After, go immediately to the emergency room. If possible, bring either the spider or a picture of it to help identify it.

More About Black Widow Spiders

If you have:

  • Two puncture wounds on the skin that cause pain and burning
  • Spreading cramping and muscle pain
  • Headache
  • Sweating
  • Muscle rigidity
  • Chills, fever, nausea, or vomiting
  • Severe belly, back, or chest pain

Then you may have been bitten by a black widow.

Where Do They Live?

Black widows are mostly found in warm Southern and Western states. They like to live in piles of leaves, woodpiles, or in the attic. Like the brown recluse, they only attack if they feel threatened.

What Do They Look Like?

Only female black widows are dangerous to humans. They are plump and black, roughly the size of a quarter, with a red hourglass shape on the underside of their bellies, so check the spider if you caught it or saw it.

If You've Been Bitten:

  • Clean area with soap and cold water (do not massage the tissue to prevent venom spread)
  • Remain calm
  • Do not apply a tourniquet
  • Wrap ice in towel and apply to the wound for 10 minutes, remove for 10 minutes, then repeat
  • Get medical help immediately

These bites are rarely fatal. Only the very young, the elderly, or people with weakened immune systems are at risk of fatal reactions.4

Why Spiders Bite

While some spiders are aggressive, most spiders tend to hide and prefer dark and isolated places. Spiders often bite in self-defense, when they sense harm from another living creature. People are bitten because we may have harmed them unknowingly.

Most bites by spiders in the United States will only cause an itchy red spot that clears up in a few days. That's because most spider fangs, or chelicera, are too short to completely penetrate human skin. While some bites are almost painless, others can feel like a bee sting.

One of the main concerns about a spider bite is the potential effects of the venom. As mentioned, some dangerous species of spiders can inflict little to no pain upon biting, and so they, therefore, can go unnoticed. But some spider bites are dangerous. So identifying the type of spider and seeking treatment is important.

You can help prevent spider bites by shaking out boots, gloves, blankets, and other clothing before using them, especially if they've been in storage. Similarly, when entering storage areas, make a lot of noise to scare spiders away. If you have a spider problem, you can also seek professional help.5

Other Common Spiders That Bite

  • Hobo spiders: These large brown spiders are common in the Pacific Northwestern U.S. Symptoms of their bites are similar to those of a brown recluse. Seek medical attention to hasten the healing process.
  • Tarantulas: Common to the warm Southwestern U.S., the bite of these big, hairy spiders feels like a painful bee sting. Seek medical attention to monitor heart rate and breathing, as the bite can make breathing difficult.
  • Wolf Spiders: Found in all areas of the U.S. these spiders actually stalk and can be aggressive. Their bite can tear the skin and cause pain, redness, and swelling. They have two eyes in front that are much bigger than their other 6.

More Dangerous Spiders

Here are some more dangerous spiders that are found world-wide. Bites from these kinds of spiders in North America are extremely rare.

  • Redback spiders
  • Brazilian wandering spiders
  • Tree-dwelling funnel-web spiders

A bite from one of these spiders can produce intense pain and other symptoms such as chills, fever, nausea, vomiting, and severe abdominal pain.

Other serious cases of manifestations are leg cramps, body aches, sweating, exhaustion, tachycardia, dizziness, and shortness of breath, confusion, and even unconsciousness. A visit to the emergency room is a must if the bite victim experiences any of these symptoms.

The world's most potentially dangerous spiders, when they bite people, are the Sydney funnel-web spiders and Brazilian wandering spider.

These spiders may be more dangerous than black widows because their fangs are longer and they can inject more venom deeper into the skin.

Spider Bite Pictures

Remember that children, the elderly, and those with depressed immune systems are the most likely to have severe reactions to spider bites of any kinds. If you or the person you care for falls into one of these groups, you should seek medical attention.6

      I believe my husband was bit on the foot by a spider. I have seen atleast 3 in my house in the last week two of them in the last 2 days. It is red with a little blister in it and all swollen. He is in alot of pain. It doesn't itch and he doesnt have any other side affects besides what I have mentioned. We are keeping it elevated, using cold rice bags and antibiotic ointment on it. Also giving him motrin for the pain. I have to see the doctor tomorrow who is also my husbands doctor so we are going to have him look at it. I bought some sticky spider (insect) traps to put around the baseboards in the rooms we spend the most time in.

      Was bitten yesterday (8/11) while sleeping; two puncture marks on my right foot, near the ankle. I went to the ER when the pain in that area increased, and I had cramping in my right calf and chest as well as increased sweating. I could only guess that it was a black widow that bit me, since after looking at the various types of spider bites that was the closest that I could identify. However because the doctor was unable to deduce whether or not it was a black widow, he didn't give me any antivenom. Now today (8/12, 4 pm Central Time), it has gotten down in swelling and the cramps are limited to mild cramping in right calf and right arm (where I gotten a shot-most likely a tetanus shot), but the bite mark and the area of the shot are now deep blue/purple. I've been bitten by a wolf spider once but it did not look like this; I have severe hemophilia type A, so I'm not sure if I'm in a critical situation or not.

      I got bit by (what I believe to be) a spider on the back side of my knee and up the thigh 2 inches, it looks like the second picture from the bottom (of the ones above two or three paragraphs) and I think I was sleeping whilst it happened, texture of a rash, not painful, not itchy, not sure what it is. I did later find a spider in my room beside my bed, I killed it to fast to get a good look but it looked like a black house spider. Any clues anyone?

      I have so many spiders on my pool patio so yesterday there was this really ugly one chasing me,via scared to death of spiders so I got a broom and killed it but it was peggie and baby spiders were everywhere , and one bit me on my small finger within an hour after being bit my whole left hand was in so much pain,I almost went to Yue hospital then later on I started getting really sick to my stomach

      Today still have little pain but nothing like yesterday Thank God.I will say this one thing that researchers & Doctors do not have all the answers to bug bites, because a lot of people like myself to do report them ( Spider bites, Bug Bites), Because I know for a fact that I was bitten by a spider not a Black Widow or Brown Recluse but a spider and I had some pretty awful side effects, so God help anybody that does get bitten by a really Bad Spider. One more thing this site is not for comments about whom is going to become President of the USA

      I was bitten by a unknown spider. I did not feel the bite but the next day on my hand there was a small blister and around the blister was an almost dark red almost purple. When I put ice on it. it did the total opposite to my hand the blister expanded and also I got swelling around the area. well it got so uncomfortable so I thought that I would try and pop the blister and a thick darkish yellowish puss came out when I barely popped a hole in the blister. I drained it as much of it I could. well I cleaned it with hydren peroxcide, then I put some neosporin and some anti itch cream and then wrapped it. every half an hour I would pour some hydren peroxcide every half an hour then squeeze what I cound get out of my hand. well it is starting to look better but I had tried pouring rubbing alcohol on it. it didn't hurt when I poured it on my hand after I poured a lot on it I took a tissue and squeezed it as hard as I could. my hand is still swollen but it has been pussing it all out I have had no symptoms from the bite but would like to all types of spiders that have similar symptoms that I got

      This article has nothing about the Yellow Sac Spider. This is responsible for the majority of bites people endure since the spider is nocturnal & comes out when people are asleep & the lights are off. I have read many articles on this species & they will bite unprovoked. It is an aggressive spider at night. It is a hunter spider & is seeking out food. My opinion is that the spider cannot find any insects in my home & even though human blood is not something they ingest, the warmth of our bodies suggests that it might be nutrition, so they bite you. I have had Terminix in my home 5 times this year complaining about this species & despite their intentions, I am still getting bitten. The bites occur mostly on my neck , head & upper chest. Always where the blanket stops & skin is exposed. Funny thing that I never get bitten on my arms, hands or other places. Once in a while I will have a bite on my butt or stomach but it is rare. I think I have to move into a brand new home & make sure it is caulked to the max, because I have had these bites for 50 years plus now.

      My 13 yr old daughter wakes up with bites on her legs and hands. She is in her bed. I seriously did my homework on bedbug hunting, and found no signs of bedbugs at all- I even go in her room at around 1a.m. To see if I can see something, yet there's nothing. I have 2 other kids in their rooms. They have no bites at all. My husband and I have no bites.

      We think it may be spiders. We do have brown spiders in our house. My question is ... Has anyone had any experience in spiders biting you while you sleep? My husband sprayed bug spray around her bed and window, the next morning my daughter found a dead brown fuzzy looking about a little bigger than a dime size spider, on her bed! yet she had 3 new bites that night. THankYoU for reading anyway. If someone has any suggestions or ideas please write back! Thank you

      "Rule of thumb, to anyone out there on the internet is, NEVER allow yourself to be bitten by any spider period"

      was so shocked by some of the incredibly ignorant comments I stumbled across while reading various Spider bite articles I felt I had to respond to the most  moronic statement from somebody calling themselves "Mountain Lion" that "no spider can kill a human” which is tantamount to stating no human has ever killed an animal or that the Sea Wasp jelly fish, Chironex Fleckeri, is as harmless as a bowl of jello:-)

      From Latrodectus (Black Widows) to Phoneutria (Brazilian Wandering spiders) to Atrax robustus (Sydney Funnel Web), Loxosceles and so forth, there is ample, readily available documentation detailing scores of human fatalities attributable to various species over the decades as mentioned above. Various Phoneutria sp. for instance, are considered to possess the most virulent spider neurotoxin yet measured in a lab and fortunately for human victims, the Phoneutria spiders (mainly P. fera and P. nigriventer) are very careful with how much venom they inject unlike the primitive Mygalomorph spiders i.e., the Sydney Funnel web and still, there have been documented human fatalities from the Phoneutria bite (see Wolfgang Bucheral’s studies in his book "Venomous Animals and their Venoms Vol. III”) among the more notable.

      If spiders like Phoneutria injected a full load per every chance encounter with humans, their bite could result in a possible fatality every time if antivenin was not available. Lastly, as per some of the “chats” and internet comments I have read that blabber on touting how “harmless” most North American spiders are, I say NEVER assume a spider is "harmless" which is one of the most absurd fallacies promoted by clueless morons. For instance, Dolomedes tenebrosus, which is abundant in my area of New Hampshire, certainly isn't known to possess a venom toxic enough to cause substantial damage to humans, however; the Dolomedes or Lycosides (Wolf spiders) can not only inflict a painful bite, but depending on a persons immune system, possible allergies and where the bite occurs, almost anything is possible. 

      I know a roof contractor who suffered a horrendous bite reaction from a large Dolomedes tenebrosus that bit him while he was nailing in shingles on a roof job. He told me he accidentally trapped the spider and it bit him twice on his index finger than ran off. Not only did he suffer immediate intense pain due to the mechanical laceration from its chelicerae, within a few hours, the local bite area developed into a severe necrotic lesion accompanied by systemic effects such as nausea and chills. Even taking into consideration, this man might have had either a compromised immune system or obscure allergy/sensitivity to arachnid venom, never the less, it strikingly illustrates the potential danger of any spider bite.

      Rule of thumb, to anyone out there on the internet is, NEVER allow yourself to be bitten by any spider period, its simple common sense unless somebody is a masochist. The only thing more reckless would be to vote for Donald Trump:-)

      I'm pretty sure I was bitten by a hobo spider the other day. There are 2 little holes (fang marks) on my ankle and two red lesions, 6" and 12" further up my leg, which I now believe are the results of the venom from each fang. Has anyone ever heard of this? Only other symptom was severe sweating at times over the past two days. Of course, I work tomorrow (Friday) & Monday, so it might be 4 more days till i can see my doctor. Ugh!

      I recently had shomteing similar happen to me except my bed WAS actually full of spiders. I was about to go to sleep one night, when I saw a few tiny spiders on my blanket. I got up and looked at the foot of the bed and there were several dozen more. Then my eyes moved to the basket of freshly cleaned and folded laundry, and guess what...teaming with tiny spiders. I'm pretty sure an egg sac of baby spiders had just hatched ON my bed. Now usually, I hate killing spiders. I will take them outside or just leave them, but there were 100 baby spiders crawling all over my bed, and I wanted to go to sleep. So I spent the next hour and a half on a spider killing rampage with some tissues. I then spent the night on my futon in the next room, and washed my sheets and vacuumed very thoroughly in the morning. It was super traumatic.
