It’s Best!

Earwigs are one of the most disliked insects. The European earwig is the most common species. It can be found outside and inside the home. They enter a house with the help of a host – on humans, clothing, vegetables, newspapers, etc. Earwigs are reddish-brown, approximately 4/5 of an inch (2 cm) long with antennae and a noticeable set of pincers which protrude from the abdomen. The pincers of the male are curved whereas those of the female are straight. The female uses her pincers to protect herself and eggs from other insects, but they cannot harm humans.

Earwigs have wings but they are rarely used to fly. Earwigs wait for darkness to begin their search for food and shelter. They enjoy dark, moist areas and feed on decaying plant and animal matter. They also cause slug-like damage to leaves, petals, fruit and vegetables. One way to determine if a slug or earwig is the cause of damage is to look for a slimy substance which slugs leave behind. Earwigs also damage vegetables by entering and enlarging existing holes.

Earwigs can be beneficial in the garden if they can be prevented from damaging vegetables and flowers, and entering the household. It is important to avoid killing earwigs because they are predators of some small insect pests such as aphids.

Life Cycle

The life cycle of the earwig consists of egg, nymph and adult. In early spring, after overwintering in soil, the female earwig lays up to 60 eggs in the top section of soil. In about seven days, the eggs hatch and nymphs emerge. The female tends to the eggs and nymphs for the first two weeks. The nymphs are similar to adults, only smaller. Over a 70 day period, the nymphs pass through four growth stages before becoming an adult. Egg laying can take place twice per year (spring and summer).

Adult earwigs will be most noticeable in July, August and September. Earwigs live for approximately one year, but most often the males die during the winter months.

Earwigs get their name from a myth that they crawl into a sleeping person’s ear and reach all the way into the brain.
