Identify how earwigs are entering your home
Earwigs are small, nocturnal insects that love dark, damp places. When you find one under a rug, the first question to ask is how it slipped inside. Look closely at the perimeter of every room: door frames, window screens, foundation cracks, and gaps around pipes are common entry points. Even a hair‑thin opening can be enough for an earwig to squeeze through because of its flexible body.
Start by turning on a bright flashlight and scanning the lower edges of doors and windows. You’ll often see a faint line of dust or a tiny gap where the frame meets the wall. In the bathroom and kitchen, check the backs of cabinets and under the sink where plumbing penetrates the wall. If you see any space larger than a quarter of an inch, that’s a likely route.
Seal these openings with caulk, weather‑stripping, or expanding foam. For larger gaps around pipes, use a metal mesh or pipe‑sleeve before applying sealant; earwigs can chew through soft material but not metal. By eliminating the pathways, you cut off the easiest way for them to wander inside, reducing future sightings dramatically.
Control moisture to make your house less attractive
Moisture is the biggest attractant for earwigs. They thrive in damp environments because it helps them stay hydrated and provides a place to lay eggs. To make your home less inviting, start with a thorough inspection of all water‑related fixtures.
Check faucets, showerheads, and toilet tanks for drips. A slow leak may be invisible to the eye but creates a steady source of humidity. When you find a leak, turn off the water supply, replace worn washers, or call a plumber if the problem is more serious. Next, examine the under‑sink areas and behind appliances for standing water or condensation.
Improving drainage around the foundation also helps. Ensure that gutters direct water at least six inches away from the house, and grade the soil so water flows away rather than pooling near the walls. If you have a basement, use a dehumidifier to keep humidity levels below 50 %. The drier the environment, the less likely earwigs will seek shelter inside.
