Earwigs can cause damage to cultivated plants. They can be a nuisance when they migrate indoors. Migrations of earwigs numbering in the 100's have been reported. They seldom become established indoors. Some species will emit a foul odor.
Earwigs can be of value as predators of certain insect pests.
Earwigs are nocturnal. During the day they will be found in moist shady places, under wood piles, stones, boards, compost piles, flower beds, and other secluded locations. When earwigs migrate indoors, they hide in cracks and crevices around baseboards and other locations. They may be found in potted plants and cut flowers. They normally do NOT crawl into people's ears.
