About Earwigs

Order: Dermaptera
Earwigs are common outdoor pests recognized by their distinctive pincers. They are typically found in damp environments and are often seen around landscaping, mulch, and foundations. While they prefer outdoor habitats, earwigs may enter homes and businesses in search of moisture, especially during rainy periods or changes in weather.

How to Identify Earwigs

Size

  • About 1/2 to 1 inch long

Color

  • Reddish-brown to dark brown

Identifying Characteristics

  • Pincer-like appendages at the rear of the body
  • Elongated, flattened body
  • Short wings (rarely used for flight)
  • Fast-moving when disturbed

Where You’ll Find Them

  • Under mulch, leaves, and debris
  • Around foundations and landscaping
  • Inside basements, bathrooms, and kitchens
  • Near cracks, gaps, and entry points

Behavior and Risks

Earwigs are nocturnal and hide during the day in damp, protected areas. At night, they become active and may wander into structures through small openings in search of moisture and shelter. Homeowners may notice them in sinks, bathtubs, or along baseboards, especially after heavy rain. They may also be found near entry points or in areas with high humidity.

While earwigs do not damage structures and are not considered dangerous, they can use their pincers defensively if handled. Their presence indoors is typically a sign of favorable outdoor conditions or moisture issues. Reducing moisture, clearing debris, and sealing entry points are key to preventing earwig activity indoors.
