Earwigs primarily feed on dead and live plants, which is why you are most likely to see them in your garden. Here are some physical features of earwigs to help you identify and control them.

  • Body Shape: Earwigs appear slender, long, and flattened, a body shape similar to crickets and stick insects. Like most other insects, the earwig has six short, thin legs adapted for running.
  • Size: Earwigs are generally small and have lengths of between 0.16 – 3 inches without pinchers. A male garden earwig is slightly more giant and weighs slightly more than the female.
  • Wings: Not all species have wings. However, most adult garden earwigs possess two pairs of tiny yellow wings often folded at their back.
  • Pincher: The most notable physical feature of the earwig is its pinchers used as a defense mechanism. The pincher is a pair of formidable forceps protruding from their very flexible abdomen.
