Beetles may fly to buildings and homes to hibernate for the winter. Beetles enter the walls of a building through cracks and crevices. However, this does not mean they will enter the living spaces. The majority will stay in the wall spaces.
During the warmer days in late winter and early spring, overwintering beetles in a home’s wall space will become active and while looking for an exit, they may enter the living areas and become a nuisance. Warm temperatures in the living areas tend to attract these active beetles while they search for an exit and draw them inside the living space.
Once inside, beetles are usually just a nuisance pest. Sometimes, however, their feces may cause stains and discoloring on curtains, upholstery, clothing, and other resting places. Occasionally, beetles “bite” people, causing a skin irritation. Because of this, finding a safe way to keep beetles out of your home is best for pets and children.
