Earwigs in House
Earwigs often invade a home for protection and moisture. They can easily be controlled and pose little threat to humans.
Finding earwigs in the house does not mean they are breeding in your home. Similar to cockroaches Earwigs come indoors to hide from daylight. They are attracted at night to lights and moist areas inside the house. Moist areas around the foundation of a home, near water spigots, and moist areas inside the home such as in unventilated crawl spaces attract earwigs. Repeatedly finding earwigs inside often means there are cracks and other access points through which the insects are entering.

Other than being a nuisance, earwigs pose little threat to a house. Earwigs can however spread bacteria and other micro-organisms which can be a health risk to residents.
Earwigs can be controlled by pesticides and trapping, and also by good sanitation practices. Old tuna fish cans filled with fish or vegetable oil can be placed near problem spots such as debris or mulch piles. Once trapped, earwigs can be killed with soapy water. Dusts and residual sprays can be used indoors to control earwigs. These should be sprayed on baseboards, under cabinets, and behind shelves and appliances. Other places to inspect and treat include under sinks, behind dishwashers and behind bathtubs—anywhere moisture can build up. Prevent earwigs from coming inside the house by eliminating moist spots near the structure. This can include clearing up debris or ensuring your property is drained properly, keeping water away from the foundation. Make a 12-18” gravel border between your home and any landscaping. Seal up entry points such as windows and pipe entrances.
