What are Earwigs?

Earwigs are primarily active at night (nocturnal) and occupy the moist and wet places of gardens and potted plants. They are omnivorous, which means earwigs eat dead decaying wood, leaves, and other plant material. They hide in wood piles, leaf litter, and basements during the daytime.

Pincher bugs - how to get rid of earwigs

Pincher bugs appear as dark brown, which reminds me of cockroaches.

They belong to the insect order Dermaptera. There are nearly 2000 species of them. Earwigs are also known as pincher bugs because of the two appendages or pinchers. These pictures are present on the back of their abdomen.

Note: The name “earwigs” comes from an old myth that means “ear wiggler.” It is believed that these insects seek human ears to live. In France, they are called “ear piercers,” and in Germany, they are called “earworms.”

Earwigs are considered natural composters and predators for most insect pests of houseplants and gardens. They feed on the aphids, larvae, slow-moving pests, and other armyworms and help the gardeners keep pests populations at lower levels.

Also, they feast on decaying organic matter and use it as hiding places during the daytime. In this way, they play a beneficial role in plant health and do not cause any damage to garden plants. However, keep a close eye on the earwig populations because they munch on young seedlings when they are in high numbers.

Identification of Earwigs

These nocturnal bugs are reddish-brown with long, slender, and flattened bodies. They are the only members of the insect order Dermaptera and prefer places of excess moisture. Earwigs are almost 3 to 4 inches long and have specialized pichers at the tail side, used to capture the prey for defense and mating.

A few species of earwigs have wings, but they rarely fly. Mainly they crawl in search of their food and are not strong fliers. Due to the pincers, they do appear as scary, but earwigs are harmless to humans and pets.

Life Cycle of Earwigs

The active period for earwigs is early summer. The adults lay almost 20 to 30 creamy-white eggs in the underground nests. Female earwigs lay eggs in January and February. At the same time, the newly hatched larvae are protected in underground nests and only emerge during April.

When the young nymphs leave for a food search, they can fence the danger. After 4 to 5 nymphal molting, they turn into adults. The larvae are similar to adults in appearance and lack large wings and large appendages in the abdomen.
