Both males and females have forceps. Earwigs prefer moist, dark areas. They are most active at night and seek shelter during day. They are commonly found in mulch, organic debris, cracks and crevices, under flower pots and boards. They frequently enter the house and are often found in the basement or crawlspace.
Earwigs feed on living or dead plant material and some insects.
Generally, earwigs are not destructive. They are not poisonous and generally will not bite or sting humans. They may pinch the skin with their forceps. With large numbers, they may feed on tender plants and may damage lettuce, strawberries, dahlias, marigolds, zinnias and roses. Discourage earwigs by eliminating their desired habitat.
