They are nocturnal and their presence or damage may go unnoticed until harvest. There are two generations per year.
Earwigs feed on fruit and foliage.
Foliage feeding is of little concern in mature trees. However, shoot-tip feeding on young trees may stunt normal growth. Earwig feeding on fruit results in shallow, irregular holes. Remove weeds from around the base of trees. Keep orchard clear of prunings or other debris under which earwigs may nest.
