Earwig Identification Guide
Earwigs are instantly recognizable by their rear pincers (cerci). At 0.5–0.75 inches, dark reddish-brown, they look menacing but are not dangerous to humans. The pincers are used for defense and mating, not attack. Earwigs are nocturnal, hide in damp crevices during the day, and are one of the most frequently misidentified garden insects in Philadelphia.

Frequently Asked Questions
Do earwigs crawl in ears?
No — this is a myth. Earwigs have no interest in human ears. The name comes from Old English folklore. There is no documented case of an earwig burrowing into a human ear.
Are earwig pincers dangerous?
Earwig pincers can lightly pinch if handled but rarely break skin. It is not painful and they inject no venom. They pose no meaningful threat to people or pets.
How do I stop earwigs from coming inside?
Eliminate moisture around your foundation, clear mulch and leaf litter from against the house, and seal entry points. Yellow outdoor lighting attracts fewer insects than white light.
When should I call a pest control professional?
