First thing to know about earwigs is that they do NOT crawl into human ears to make nests or lay eggs or pinch your ear drum as my older brothers told me. They also do not bite or pinch people. In fact, bug literature about earwigs states that they are harmless to people. The earwig name was intended to be “earwing” but the “n” was dropped for some reason and the myths grew.
There are people that insist they have been bitten or pinched, but this is highly unlikely. The pinchers are used for defense, in battles to win a mate or to ward off predators. The pincers also help the earwig fold its wings to close them. Yes, they have wings, but don’t panic they rarely fly.
