An earwig “bite” typically leaves two small red pinch marks spaced a short distance apart, caused by the pincers at the tail end of the insect rather than its mouth. The marks may be slightly swollen and red, but in most cases the discomfort is mild and fades quickly.
What the Marks Actually Look Like
Earwigs don’t bite in the traditional sense. They pinch using a pair of curved, horn-like pincers (called cerci) at the rear of their abdomen. Because the pincers have two tips, the injury typically shows up as two small red dots close together, almost like a tiny set of tweezers pressed into your skin. The surrounding area may become slightly red and swollen, similar to a minor scratch or scrape.
The marks are usually small enough that they can be easy to miss. Unlike mosquito or bed bug bites, an earwig pinch doesn’t produce a raised, itchy welt. There’s no venom involved whatsoever, so you won’t see hives, widespread redness, or an allergic skin reaction from the pinch itself. Most pinch marks heal on their own within a day or two without leaving a scar.
How It Feels
The pinch ranges from barely noticeable to a brief, sharp sting, depending on the size of the earwig and how hard it clamps down. Some people compare it to a small tweak of the skin. The pain rarely lasts more than a few minutes, and there’s no lingering burning or throbbing the way you might experience with a wasp sting or spider bite. If the pincers break the skin, you might notice a tiny amount of bleeding, but this is uncommon with smaller earwigs.
Why Earwigs Pinch
Earwigs are nocturnal and generally want nothing to do with people. The pincers exist primarily for mating and defense against predators. An earwig will only pinch a human when it feels trapped or startled, like when you roll over onto one in bed, pick up a damp towel it’s hiding under, or reach into a dark garden pot. They don’t seek out humans to bite, and they don’t feed on blood.
If you’ve been pinched, you may also notice a strong, unpleasant smell. Earwigs release a yellowish-brown secretion when frightened or crushed, which acts as a chemical deterrent against threats. It’s harmless to your skin but can linger on your fingers.
How to Tell It Apart From Other Bug Bites
The twin-dot pattern of an earwig pinch is its most distinctive feature. Here’s how it compares to bites people commonly confuse it with:
- Bed bug bites appear as raised, itchy red welts, often in clusters of three to five arranged in a line or zigzag. They can take up to 14 days to show up and tend to itch intensely. An earwig pinch shows up immediately, doesn’t itch, and appears as a single pair of marks rather than a cluster.
- Mosquito bites produce a puffy, round bump that itches within minutes. Earwig pinches don’t itch and aren’t raised into a dome shape.
- Spider bites often leave a single puncture point (or two fang marks very close together) and can develop into a larger area of redness, pain, or blistering over hours. Earwig pinches stay small and resolve quickly.
If you wake up with multiple itchy welts in a pattern, you’re almost certainly dealing with bed bugs, fleas, or mosquitoes rather than an earwig.
Basic Care for an Earwig Pinch
Wash the area with soap and warm water. If the skin is broken, apply a small amount of antiseptic ointment and cover it with a bandage. A cold compress can reduce any minor swelling. Over-the-counter pain relief is rarely necessary, but an anti-itch cream can soothe irritation if the area feels tender.
Signs of Infection to Watch For
Infection from an earwig pinch is rare, but any break in the skin can potentially let bacteria in. Watch for signs that suggest a secondary infection developing over the following days:
- Expanding redness or warmth around the pinch site, spreading beyond the original mark
- Increasing pain or swelling rather than gradual improvement
- Red streaks radiating outward from the wound
- Pus or yellowish drainage from the site
- Fever, chills, or swollen lymph nodes
These symptoms can indicate cellulitis, a bacterial skin infection that needs treatment. If the redness keeps spreading or you develop a fever, that warrants medical attention. For the vast majority of earwig pinches, though, the marks fade within a couple of days with no issues at all.
