Pictures of brown recluse bites on humans

THE INSIDER Summary:

  • A man who says he was bitten by a brown recluse spider posted photos on Imgur showing how his skin healed up after the bite.
  • In rare cases, brown recluse bites cause serious skin wounds that make some tissue die and turn black.
  • Warning: The photos are graphic — but they're also kind of amazing.


Ever wonder what it looks like when you get bitten by one of the world's most feared spiders? A gnarly photo series recently shared on Reddit will show you all the gory details. 

In the photo series (originally posted on Imgur in 2016 but recently re-shared on the /r/popping subreddit), Redditor KilledTheCar showed how his skin healed after he was bitten by a brown recluse spider. It's one of the few spider species in the U.S. that experts consider "medically important."

Brown recluse bites in particular can cause what's called a necrotic wound. That's when parts of your tissue actually die and turn black. 

And that's exactly what happened to KilledTheCar. Scroll through his photo series and you'll witness a healing saga for the ages: First the skin at the bite site looks crinkled and brown, then it starts to turn black and dry up. Next, an infection infuses the wound with pus, and finally — slowly — new skin starts to cover it up for good.

In the comments section of the new Reddit thread, KilledTheCar revealed that he was bitten in Mississippi (well within the brown recluse's natural habitat) and that it felt like "just the tiniest little pin prick."

He also wrote that he went to the ER about six hours after the bite because he was vomiting and experiencing chills. Eventually, a doctor suspected that it was likely a brown recluse bite based on the symptoms, KilledTheCar wrote. 

It's a terrifying story — but it's important to put it in context. According to spider researchers at University of California Riverside, a full 90% of brown recluse bites are not "medically significant" and often heal up on their own. Plus, the brown recluse doesn't travel far outside of its usual geographic range (see it on a map right here) and lots of other skin issues are often misdiagnosed as brown recluse bites. And finally, it wasn't just a spider bite: KilledTheCar said tests revealed that his wound was infected with staph and pseudomonas bacteria to boot.

If you really want to see the photos, brace yourself and check out the entire album right here. It's gross, to be sure but it's also a fascinating look at how the skin can heal up even after the nastiest injuries.

Brown Recluse Spiders

It may surprise you to learn that most spiders found in the United States are not capable of puncturing human skin. Two exceptions to this are the black widow and the brown recluse.

How to Identify a Brown Recluse Spider

  • Appearance: Distinct, violin-shaped mark in the center of their backs (they are sometimes called violin spiders.)
  • Size: Relatively small in size. Male adults can grow up to one inch.
  • Where in the U.S.: Established in 16 southeastern and Midwestern U.S. states: Alabama, Arkansas, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Nebraska, Ohio, Oklahoma, Tennessee, and Texas. (Isolated cases have been documented in several other states, as well, but these are most likely a result of being accidentally transported across state lines.)
  • Where in your home: Typically live in warm, dry locations with minimal activity, such as basements, attics, below sinks, or beneath woodpiles and gardening supplies.

Brown Recluse Spider Bites

The bite of this spider can lead to health complications. However, it's important to note that brown recluse bites are rare. Most reported cases actually turn out to be skin infections or bites from another insect.

Among documented bites from this spider, more than 90 percent of cases do not involve serious complications. For the remaining 10 percent, medical attention may be required.

Bites from these spiders are usually found on the hands, arms, or legs. The bites typically occur when the spider accidentally bumps into a person and bites to protect itself.

Signs of a Brown Recluse Bite

A bite from this spider may not be noticed immediately because the bite itself is usually painless. However, the bite can cause serious symptoms including:

  • Pain, ache, or burning sensation at the site of the bite
  • Redness, swelling, bruising, itching, or blistering at the site
  • Pain in the abdomen, chest, back, or legs

More Severe Symptoms That Can Sometimes Occur

  • Rash
  • Fever
  • Vomiting
  • Dizziness
  • Chills
  • Necrosis (death of skin tissue) around the site

The area around the bite can have a red bullseye appearance or it can have a blueish, bruised appearance.

Stages of a Recluse Spider Bite

Brown recluse spider bites typically go through three stages:

  1. First 24 hours: The bite will initially cause a stinging sensation. This is caused by the discharge of spider venom into the blood. The stinging may disappear after a few seconds or it may last for many hours. The sensation may be accompanied by redness, inflammation, and sensitivity at the site. It may also cause a thickening and puffiness of the affected skin. The area around the bite may have a red bullseye appearance or it may have a blueish, bruised appearance.
  2. Days 3-5: Depending on the amount of venom injected by the spider, the pain will either diminish or continue for several days. In the latter case, a blister or ulcer (open sore) may form at the site.
  3. Days 7-14: In severe cases, the skin tissue around the blister or ulcer can begin to die (necrosis), leading to the formation of a thick, black scab. This can take several months to heal.

Treatments and When to Consult a Doctor

Follow these self-care guidelines to alleviate symptoms:

  • Thoroughly wash the area with cool water and antiseptic soap.
  • If possible, elevate the affected area over the level of the heart.
  • Do not engage in any physical activity as it can spread the spider’s toxins through the body.
  • Wrap an ice pack with a towel and apply to the bite to relieve swelling and pain.
  • For pain management, take over-the-counter pain medication (but do not take aspirin, as it thins the blood).
  • Apply over-the-counter antibiotic cream.
  • Watch for more serious symptoms. If necessary, consult a doctor. If possible, bring the culprit spider to the doctor for identification and investigation.

Avoid the following:

  • Heat or warm compresses
  • Cutting the affected tissue or using any type of suction device to remove spider poison
  • Hydrocortisone or other steroid creams
  • Electricity to the affected site (this can result in secondary burns and aggravate the destruction of tissue)

Hospitalization is rarely required. It is however important for patients to go for regular checkups until the wound has completely healed.

    Brown recluse spider bites often go unnoticed initially because they are usually painless bites. Occasionally, some minor burning that feels like a bee is noticed at the time of the bite.

I was bitten 25 years ago by brown recluse spider. Took a long time for the bite area to heal going through several stages. Fast forward 25 years, the scaring flared up again with less intensity than the first time. Once again my skin died in the area but healed once again. Has anyone else ever had that experience???

Your articles sure are disgusting, but I'm enjoying them! lol We have brown recluse spiders here in the Midwest, too. One online article instructs people to use mint to repell spiders, but there was mint planted along one side of the house where my apartment was downstairs in Mission, that these or similar spiders absolutely LOVED. They loved it while it was growing, and look out after it dried because it was a spider metropolis. When I first moved in I was literally killing 10-12 spiders a day! Thank goodness I got it under control.

In any case, I appreciate the detailed medical advice regarding what to do in the unfortunate circumstance that someone is bitten by one of these.

shaped like a penny, blistery and infection has set in. Its eating my skin and the itch is a torture... day after my whole left side of face was blown up... I need some advice please. I think this is a brown recluse... very hard around the bite

My husband got a bite I used wound care xero petroleum guaze everyday ! It's closed the wound and staph plus on 2 antiobotics ! 2 times a day clean the affected area with soap and water then use sterile water rinse the area and apply the xero petroleum guaze ! It took 8 weeks to close but worked !

I think I was bit by a spider today it had a puncture mark and was swollen and about 8 hrs later there was a blister that I punctured to get the poison out so now it looks like two bites. Im nervous should I go to the doctor

Please Tell me what this is

It's the 7th day today, is it ok to apply granules?

drpaul007 on July 23, 2015:

I agree with venom er, along with the proven fact that one can render the venom as non-invasive by the use of electrical stimuli. Do your own research rather then repeat what others have stated as incorrect.

Venom ER on July 17, 2015:

Please remove these photos. Most are not related to brown recluse bites in the least. For example the Lyme Disease erythema migrans "bulls-eye" followed by a photo of an infected black widow bite. Next time, please do some research before posting "credible" information, okay?
