Earwigs are nocturnal insects, although they are sometimes encountered during the day when present in large numbers. They are known to attack fruit, flowers, and vegetables, and particularly seedlings. They can cause serious damage to gardens. The roots of young shrubs are often their primary target, but since they have no specific diet, they are practically omnivorous. They can be found all around the house searching for food and shelter, and even climbing the walls. They can get in anywhere and live in cracks and crevices.
