Earwigs don’t technically bite. What they do is pinch. Those intimidating pincers on their back end (called cerci) are what earwigs use to defend themselves, and they will occasionally clamp down on human skin if they feel threatened. The pinch can be surprising and mildly painful, but it’s not dangerous. Earwigs carry no venom and don’t transmit diseases.
Pinch, Not Bite
The pincers at the tail end of an earwig are modified appendages used for defense and for wrestling with other earwigs. They’re not mouthparts. When an earwig pinches you, it’s a reflex to being startled, picked up, or pressed against your skin (often when you reach into a damp pile of mulch or slip on a shoe where one has been hiding).
Male earwigs have larger, curved pincers that can reach up to 3/8 inch long, while females have smaller, straighter ones. The size difference means a pinch from a large male is more likely to break the skin than one from a female, though neither delivers much force. Most pinches leave a small red mark that fades within minutes. There’s no venom involved, so you won’t experience an allergic reaction, hives, or swelling from the pinch itself.
What a Pinch Feels Like
An earwig pinch feels like a quick, sharp squeeze, similar to being nipped by a small hair clip. It’s startling more than painful. In most cases the skin isn’t broken at all, and the sensation fades almost immediately. If a larger male earwig clamps down hard enough to break the skin, you’ll see a tiny mark or scratch, sometimes with a small drop of blood. It’s comparable to a minor paper cut.
When to Clean the Wound
If the skin isn’t broken, there’s nothing you need to do. If it is broken, wash the area with soap and warm water. Earwigs live in damp soil, decaying leaves, and organic debris, so their pincers can carry bacteria from those environments. A simple wash is usually enough to prevent any issues. Applying an antibacterial cream to the broken skin adds an extra layer of protection.
Redness or mild swelling around the pinch site can be soothed with an ice pack. These symptoms typically resolve within a day. In extremely rare cases where a pinch wound is left dirty and untreated, a secondary bacterial infection can develop. Signs of infection include increasing redness that spreads outward, warmth, swelling that gets worse rather than better, or pus. This is uncommon but worth watching for.
On very rare occasions, the tips of an earwig’s pincers can break off in the skin. If you notice a small hard fragment embedded in the wound, have it removed by a medical professional to avoid infection.
Why Earwigs End Up Near You
Earwigs are nocturnal and attracted to moisture. They spend the day hiding in tight, damp spaces: under rocks, inside mulch, beneath potted plants, in rolled-up newspapers, or inside shoes left by the door. They don’t seek out humans. Most encounters happen when you unknowingly disturb their hiding spot.
Earwigs enter homes through cracks in foundations, gaps around doors, and poorly sealed windows, especially during hot or dry weather when they’re looking for moisture. They’re also drawn to white outdoor lighting at night, which brings them closer to entry points. Once inside, they gravitate toward bathrooms, basements, laundry rooms, and kitchens.
Keeping Earwigs Out of Your Home
The most effective approach is removing the conditions that attract them in the first place. Clear mulch, leaf litter, and wood piles away from your home’s perimeter. Clean out gutters where damp leaves accumulate. Fix leaky drain spouts and grade the ground around your foundation so water drains away from the structure rather than pooling against it. Ventilating crawl spaces helps reduce the moisture earwigs are looking for.
Seal cracks and gaps in your foundation, around windows, and along door frames. If earwigs are congregating near your porch lights, switching to yellow or sodium vapor bulbs makes the area less attractive to them.
Indoor pesticides are not recommended for earwigs. They won’t stop new earwigs from entering, and the insects are easy enough to manage by sweeping or vacuuming them up. If you’re seeing earwigs inside regularly, it’s a sign there’s an entry point or moisture source that needs attention rather than a chemical solution.
Earwigs and the Ear Myth
The name “earwig” comes from an old folk belief that these insects crawl into human ears. They don’t. While any small insect could theoretically wander into an ear canal, earwigs have no interest in doing so and aren’t built for it. They prefer dark, damp soil and plant matter. The myth has persisted for centuries, but there’s no biological basis for it.
