Earwigs often come indoors to hide, or they conceal themselves under outdoor furniture, hoses, garbage cans, or poor fitting well caps. Both adults and the young require moisture to live.
They do not breed indoors but simply hide, then become active at night. Some earwig species are attracted to lights.
The name “earwig” derives from a false European superstition according to which these insects enter the ears of sleeping people and bore into the brain. In fact, earwigs rarely bite, usually only when sat upon or handled, and their bite is only mildly painful.
