Earwigs end up indoors when conditions outside become too dry, too hot, or too cold. They’re moisture-loving insects looking for shelter, not setting up a permanent colony in your home. They don’t bite, don’t carry venom, and despite the old myth, they have zero interest in crawling into your ear. If you’re seeing one or two, it’s easy to handle yourself. If you’re seeing them regularly, you likely have a moisture problem worth fixing.
Why Earwigs Come Inside
Earwigs need damp, cool, dark environments to survive. Outdoors, they hide under rocks, mulch, woodpiles, and leaf litter during the day, then come out at night to feed. When the weather shifts, whether a dry spell, a heat wave, or a cold snap, they migrate toward the nearest source of moisture and shelter. Your house fits the bill perfectly.
The most common indoor attractants are exactly what you’d expect: leaky pipes, condensation around windows, damp basements, and humid crawlspaces. Earwigs don’t reproduce or thrive indoors the way cockroaches or ants do. They’re temporary refugees. But if your home consistently offers what they need, you’ll keep seeing them.
Where They Hide Inside Your Home
During the day, earwigs tuck themselves into tight, damp spots. Check under bathroom and kitchen sinks, around exposed pipes, along baseboards, and in the corners of basements or laundry rooms. They also hitchhike inside on potted plants, bundles of newspaper, firewood, and grocery bags that sat on the ground. If you’ve recently brought any of those items indoors, that may explain a sudden appearance.
You’re most likely to spot earwigs at night, since they’re nocturnal. Flipping on a bathroom light and seeing one scurry across the floor is the classic encounter.
Are Earwigs Dangerous?
The name “earwig” comes from an old folk belief that these insects climb into human ears and lay eggs in the brain. That doesn’t happen. Earwigs have no reason to seek out ears and no ability to burrow into tissue.
The pincers (cerci) at the back of their body look intimidating but are weak. Earwigs never bite. They may pinch if you handle them or accidentally press against one, but the pincers rarely break skin. If they do, the result is minor redness and discomfort, similar to a small scratch. There’s no venom involved, so allergic reactions aren’t a concern. Clean the spot with soap and water and apply a basic antibiotic ointment. Secondary infections from earwig pinches are extremely rare and only occur if the small wound is left completely untreated.
Earwigs also pose no structural risk to your home. They don’t chew wood, damage wiring, or contaminate food the way pantry pests do. In gardens they can nibble seedlings and soft flower petals, but indoors they’re mostly just unwelcome guests.
How to Get Rid of Earwigs Indoors
Start by removing them physically. A vacuum works well for clearing earwigs from corners, cracks, and baseboards. For a simple trap, roll up a damp newspaper and leave it on the floor overnight near where you’ve seen activity. Earwigs will crawl inside for shelter. In the morning, pick up the whole roll and toss it in an outdoor trash bin.
A homemade liquid trap is another effective option, especially near doorways or in garages. Fill a small container (a yogurt cup or tuna tin) about one-third full with water, add two tablespoons of soy sauce, then pour in just enough vegetable oil to form a thin layer on the surface. The soy sauce attracts them, and the oil layer prevents them from climbing back out. Place the trap where you’ve noticed earwigs, and check it every few days.
Diatomaceous earth, the food-grade version, can be sprinkled in dry cracks, along baseboards, and around entry points. It works by damaging the thin waxy coating on the insect’s body, causing it to dehydrate. It’s safe around pets and people but becomes ineffective once it gets wet, so it’s best suited for dry indoor areas where you can leave it undisturbed.
Fix the Moisture Problem
Killing individual earwigs won’t solve the issue if your home keeps inviting new ones in. The real fix is reducing indoor humidity and eliminating damp spots. Run a dehumidifier in basements and crawlspaces. Repair leaky faucets and pipes under sinks. Make sure bathroom exhaust fans actually vent to the outside, and use them during and after showers.
Outside, pull mulch, leaf litter, and woodpiles at least a few feet away from your foundation. These are daytime hiding spots, and the closer they are to your walls, the shorter the trip earwigs need to make to find a crack and slip inside.
Sealing Entry Points
Earwigs can squeeze through surprisingly small gaps. The highest-priority spots to check are door thresholds, window frames, and anywhere utility lines (water, gas, cable) pass through exterior walls. Foundation-to-siding joints are another common entry point that’s easy to overlook.
Install or replace weather stripping around doors and windows. Add door sweeps to any exterior door that has visible light underneath it. Use caulk or expanding foam to seal cracks in the foundation and gaps around pipes. These steps also help with other pests and with energy efficiency, so the effort pays off more than once.
When a Few Earwigs Become a Pattern
Seeing one or two earwigs over the course of a summer is normal in most climates and doesn’t require any special response beyond squishing or vacuuming. If you’re finding them daily, or in multiple rooms, that points to a sustained moisture source or an unsealed entry point that needs attention. Work through the steps above systematically: reduce moisture, seal gaps, and set traps. Most people resolve the problem within a week or two without needing professional pest control.
If numbers stay high after you’ve addressed moisture and sealed entry points, a pest control professional can apply a perimeter treatment around your home’s foundation. But for the vast majority of earwig sightings indoors, the combination of drying out your space and closing off access routes is all it takes.
