Earwigs Facts & Information

Earwigs are flat, narrow, and grow up to 1 inch long. Their color ranges from rusty brown to black, and what makes them stand out is that set of curved pincers at the back. Males have exaggerated, forceps-like ends, whereas females’ pincers are usually straight and slimmer. They look threatening but rarely use them aggressively.

Some species have wings, and they are tucked neatly under short covers. However, they’re not great fliers; they prefer a quick scurry under the sink or across moist floors to taking off.

You’ll usually meet earwigs in moments of surprise, lifting a soggy rag, opening storage, or pulling out garden tools. Their slick bodies, twitchy legs, and sudden movements leave an impression. Aside from that, they love moist air and dim light; thus, they make themselves at home where those conditions exist.

Nonetheless, here’s something unexpected: Earwigs care for their young. Females will guard and groom their eggs until they hatch. Can you believe that? For a pest that looks this unsettling, that’s a surprisingly gentle trait.

Earwigs consistently cling to wet and hidden spaces. Outside, they burrow into mulch, cluster underneath pavers, or shelter under flowerpots. Indoors, they love slipping into places that stay humid, which basically include bathrooms, crawl spaces, laundry rooms, or garages. When the night falls, they come out to feed on rotting leaves, insects, or virtually anything organic.

Dry spells outside often drive them in. A cool and dark interior space with even minor leaks is enough to start an earwig invasion. Once they are settled, they’ll hang around unless actively disturbed, then eliminated.
