How to Identify Earwigs

Often referred to as the “Pincher Bug“, the earwig is a pest you won’t soon forget nor have trouble identifying when you see one. With intimidating pincers, long antennas, and a predictable lifestyle, you can find these creepy crawlers in and around your home when the environment suits them.

What are earwigs?

Earwigs are a nocturnal insect that make up the Greek designated Dermaptera order (“skin wings”). With more than 20 species of Earwigs in the United States alone, earwigs appear on all continents save for Antarctica. Earwigs are commonly known for the mythical story of “crawling into people’s ear” – something of which has not been proven to be scientifically correct – yet the pincers on the back of their abdomen can frighten the average homeowner.

What do earwigs look like?

Earwigs are a unique looking insect, noticeable most by their large cerci, otherwise characterized as pincers. These pincers, while harmless to people, develop from their abdomens and are used for self-defense. By the end of an earwig’s life cycle, they typically size around ½-1-inch-long and have a light to dark brownish exterior. Along with their pincers, they have 6 legs, two long antennae that protrude from the top of their head and two pairs of wings, which often hide under a thick cover. Even though most species of earwigs have wings, they often do not use the ability to fly, and generally resort to their legs for getting from point A to point B.

Earwig Safety

While earwigs may look like one the dangerous insects inside your home because of the pincers protruding from their back, they are actually quite harmless to people. If an earwig does crawl on you, it is possible that they might use their pincers to pinch the skin out of self-defense. An earwig’s pinch could potentially cause slight discomfort and in rare cases penetrate the skin. If this were to occur, simple treatment with soap and water along with an antibiotic cream to prevent infection would be all that is necessary.

Earwigs do not have a stinger of any sort and thus do not carry venom. They are not poisonous. And contrary to an old wives’ tale, there is no additional risk of earwigs crawling into one’s ear. While quite harmless, an earwig might not be a pest you want to keep around the home.
