What are earwigs doing inside the house?

Earwigs are mostly outdoor insects. They are active at night and spend daylight hours in narrow, dark and protected spaces. Outside, that can mean damp soil, mulch, loose bark, garden debris, stacked materials or the underside of pots and stones. They eat a mixture of decaying plant material, soft vegetation and small organisms. A house is not usually their preferred long-term habitat.

Does finding an earwig mean the house has a moisture problem?

Not by itself. A single earwig does not prove a plumbing leak, wet basement, damaged foundation or failed waterproofing system. It may have entered through an open door, arrived with a box or plant, or moved indoors after outdoor conditions changed.

Are earwigs dangerous?

Earwigs are recognizable by the forceps-like appendages at the end of the abdomen. Despite the old folklore surrounding them, they do not seek out human ears and are not known for spreading household disease. They may use their forceps defensively if handled, so avoid picking them up with bare hands. For most homeowners, an indoor earwig is a nuisance rather than an emergency.

What to check before calling anyone?

Remove the insect and record the location. The exact wall, fixture, doorway or cabinet matters if another appears. Look for an obvious exterior route. Check accessible door sweeps, window screens, utility openings and gaps where materials meet. Check for real moisture evidence. Inspect safely accessible plumbing, cabinet surfaces, wall-floor edges and nearby exterior soil. Compare the timing with weather.
