You’re scrolling through your phone, squinting at a red, angry mark on your skin. It hurts. It throbs. You think it might be a spider, but then you remember that multi-legged blur darting under the baseboard earlier. Now you're hunting for pictures of centipede bites to see if your leg matches the horror stories on Reddit or WebMD.
Most people panic. I get it. Centipedes look like something out of a prehistoric fever dream. But honestly, the "bite" isn't even a bite in the traditional sense. It’s a pinch. They use modified front legs called forcipules to inject venom. It's basically a pair of pincer-needles.
When you look at real-world pictures of centipede bites, you aren't going to see a clean "vampire" puncture. What you’re looking for are two tiny red dots. Sometimes they are so close together they look like a single puncture. The skin around it usually turns bright red and swells up almost immediately. It looks a lot like a bee sting, but often with a more localized, intense "bruised" look in the center.
The Anatomy of the Mark: Decoding Centipede Bite Photos
If you’re looking at a photo and the redness is spreading in a perfect circle, that might not be a centipede. Centipede marks are messy. Because the creature is often scurrying while it strikes, the "bite" can sometimes look like a scratch or a jagged tear if the forcipules dragged across the skin.
What the redness tells you
In the first hour, the site is going to look angry. The venom—which contains a mix of chemicals like histamine, serotonin, and "Scolopendra toxins"—causes your capillaries to leak. That’s why the swelling is so fast. In pictures of centipede bites taken by ER doctors or entomologists like Justin Schmidt (the guy who famously let everything sting him), the "classic" look is a raised wheal.
It’s hot. It’s firm.
If the photo shows a dark, purplish center, that’s localized tissue damage. Don't freak out. It’s rarely "flesh-eating" like a Brown Recluse bite, but it can be intensely painful for about 48 hours.

Comparing the House Centipede vs. The Giants
Context matters. If you live in an apartment in NYC and saw a spindly, feathery thing, that’s a House Centipede (Scutigera coleoptrata). Their bites are rare because they are basically the cowards of the bug world. If they do manage to pierce human skin, the mark is barely visible. It looks like a pinprick.
Now, if you’re looking at pictures of centipede bites from a Scolopendra heros (the Giant Desert Centipede) or Scolopendra gigantea, it’s a different game. These marks are significant. You’ll see bruising that can span two or three inches. The puncture holes are distinct and can sometimes bleed.
Why Your Bite Might Look Different Than the Photos
Skin reacts differently based on who you are. A healthy adult might just get a red bump. A child or someone with sensitive skin might develop "lymphangitis"—those scary-looking red streaks leading away from the bite.
Basically, your immune system is overreacting.
I’ve seen cases where a centipede bite gets misidentified as MRSA. Why? Because both cause a rapid, painful, red swelling. However, a centipede strike is instantaneous. If the pain started the second you felt the bug, it’s the venom. If the redness developed slowly over three days, you’re likely looking at an infection or a different insect entirely.
The "Dry Bite" Phenomenon
Sometimes, you get lucky. Just like snakes, centipedes can deliver "dry bites." They use their forcipules to pinch you because they’re scared, but they don't waste their venom. In these pictures of centipede bites, you’ll see two tiny red dots but almost no swelling or redness. It’ll itch for a day and vanish.

Treating the Bite: Beyond the Visuals
So you’ve confirmed your mark looks like the pictures of centipede bites you found online. What now?
First, stop scrubbing it. You aren't going to "wash out" the venom once it’s in the tissue. You want to focus on the proteins in the venom. Many experts, including those from the University of Arizona's pest management division, suggest that heat can sometimes help break down certain venom proteins, though most medical professionals still lean toward cold packs to reduce the massive swelling.
- Clean it: Use plain soap and water. No need for harsh chemicals.
- Ice: 15 minutes on, 15 minutes off. This is the gold standard for the throbbing pain.
- Antihistamines: If the itching is driving you crazy, Benadryl or a topical hydrocortisone cream is your best friend.
- Pain management: Ibuprofen is usually better than acetaminophen here because you need the anti-inflammatory boost.
When the Photos Turn Scary: Signs of Complications
Most pictures of centipede bites show a healing process that takes 3 to 7 days. But you need to watch for the outliers. If the redness starts to feel "crunchy" under the skin (crepitus) or if you see yellow drainage, that’s a secondary bacterial infection. Centipedes live in the dirt. Their "feet" and mouthparts aren't sterile.
Rarely, some people experience anaphylaxis. If the bite site is the least of your worries because you can’t breathe or your throat feels tight, get to an ER. Also, if you’re looking at your bite and you notice a "target" or "bullseye" pattern, stop looking at centipede articles. That’s the hallmark of Lyme disease from a tick, or potentially a heavy reaction to a spider.
Misconceptions That Get People in Trouble
There is a myth that centipedes crawl over you and their "feet" leave little bite marks. This is mostly nonsense. While some large tropical species have sharp legs that can cause tiny scratches—which might get irritated—they aren't "biting" you with their feet.
If you see a trail of dozens of tiny red dots, you probably walked through a patch of Chiggers or encountered bed bugs. A centipede is a "one and done" attacker. It strikes, it realizes you aren't a cricket, and it bolts.

Another thing: centipede venom isn't typically "necrotic." You’ll see some gnarly pictures of centipede bites online where the skin looks black. Usually, that’s because the person scratched the bite with dirty fingernails and got a staph infection. The venom itself hurts like a hot poker, but it rarely rots the skin.
Real-World Examples: The "Brave Wilderness" Effect
You might have seen YouTube creators like Coyote Peterson get bitten by giant centipedes for "science" (and views). In those videos, you can see the immediate physiological response. The skin becomes incredibly "erythematous"—medical speak for bright red.
The pain is often described as a 4 or 5 out of 10 on the Schmidt scale. For context, that’s worse than a honeybee but usually less than a Bullet Ant. If your bite feels like someone is holding a cigar butt against your skin, you’ve likely had a run-in with a larger Scolopendra species.
Actionable Steps for Recovery
If you are currently looking at a mark on your arm and comparing it to pictures of centipede bites, follow these steps immediately to ensure it heals properly without scarring or infection.
- Identify the culprit if possible. If the bug is still around, safely snap a photo. It helps doctors more than any generic internet picture ever will.
- Elevate the limb. Centipede venom causes localized edema (swelling). Keeping your arm or leg above your heart can significantly dull the throbbing sensation.
- Monitor the diameter. Use a ballpoint pen to draw a circle around the edge of the redness. If the redness pushes past that line significantly after 24 hours, or if you develop a fever, it’s time for a professional opinion.
- Check your Tetanus status. Any time your skin is punctured by a wild animal or insect, it’s a good idea to ensure your tetanus shot is up to date (usually every 10 years).
- Avoid "home remedies" like bleach or gasoline. These will only irritate the wound and increase the chance of a permanent scar. Stick to the basics: cold, rest, and time.
Most centipede encounters are accidental. They hide in shoes, damp towels, or laundry piles. If you've been bitten, the pain will likely peak within the first few hours and then settle into a dull ache. Keep the area clean, stay calm, and remember that despite their terrifying appearance, centipedes aren't out to get you; you just happened to sit on their hiding spot.
