Earwig

Natural Habitat

Earwigs prefer dark, cool, and moist environments. They are commonly found under rocks, logs, leaf litter, mulch, and in cracks and crevices around homes. Indoors, they may be found in basements, bathrooms, or laundry rooms.

Diet & Feeding

Earwigs are omnivorous. Their diet includes decaying organic matter, soft fruits, vegetables, flowers, fungi, and other small insects. Some species are predatory, feeding on aphids and other small invertebrates.

Behavior Patterns

Earwigs are primarily nocturnal and seek shelter in dark, moist places during the day. They are known for their maternal care, with females often guarding their eggs and young nymphs. They can be found in large aggregations, especially in damp conditions. When startled, some species may emit a foul-smelling liquid.

Risks & Benefits

Risks: Earwigs are generally harmless to humans. While their pincers (cerci) can give a slight pinch, they are not venomous and rarely break the skin. They can be considered a nuisance pest in gardens, as they can damage seedlings, flowers, and ripe fruits. Benefits: Some earwig species are beneficial in gardens as they prey on other insect pests like aphids, although their omnivorous nature means they can also be plant pests.
