These insects are about 1 inch long, reddish brown in color, and have distinctive pincers at the end of their abdomen. They are commonly found in large groups under debris, rocks, and flower pots around the outside of houses. Indoors they may occur in kitchens and bathrooms, but also other rooms in the house.
Earwigs feed on plant material such as flowers, but also feed on other insects.
The adults overwinter and lay their eggs in moist soil in the spring. The gregarious behavior of the adults and immatures may result in large concentrations of these insects in secluded locations. They enter houses through doorways and windows, but usually do not become established indoors. Sealing door thresholds and around windows may also be helpful. An aerosol insecticide will control earwigs that remain indoors.
