Corn silk is a favorite food which is often consumed as it grows. This prevents pollination and causes poorly developed ears with many kernels missing on the cobs. As populations increase and spread, the areas in which they hide become more unusual. For example, they may be found on a roof under shingles, under siding, or under items hanging on walls as well as the usual hiding places mentioned above. Because earwigs also feed on decomposing organic matter, compost and mulch may provide food and shelter.
Earwigs are nocturnal, actively feeding during the night and hiding during the day.
As morning approaches, they search for a place to hide, preferably a dark, damp area underneath rubbish, boards, wood piles, near plants, rock borders or even in a home. Generally, they do not actively infest homes, but as they go up the foundations, any open area around the sill, door or window that will allow them to enter becomes an invitation to move in. They are not known to cause any damage to homes or their contents, but they are a nuisance, especially when they turn up in unusual places. Avoid providing earwigs with ideal nesting or hiding places. Removing these hiding places is a continuous job, but the most important time to discourage is spring when plants are not yet sprouted and most outdoor items can be moved.
