Female earwigs dig small chambers in soil where they deposit their eggs. They keep their eggs moist by licking them often. Once the eggs hatch, females will seal the chambers off in order to protect the nymphs. Nymphs will remain in the chamber until their first molt.
These nocturnal insects tend to live together outdoors in large numbers in mulch, firewood piles, stumps, in soil next to foundations, and other areas that contain sufficient moisture.
