About Earwigs

The earwig family consists of over 1,000 species worldwide, with about 20 of those present in the United States. These insects derive their common name from the myth that they burrow into the ears of sleeping people to lay eggs in the brain. Though their pincers look ominous, earwigs pose little threat to humans, attacking only if provoked.

What Are Earwigs?

Earwigs are elongated, flattened insects ranging from ¼ to 1 inch in length, typically dark brown to black in color with a distinctive pair of forceps-like pincers (cerci) at their rear end. These pincers are more curved in males and straighter in females, used primarily for defense and mating rather than attacking humans.

The name “earwig” comes from an old European myth that these insects crawl into people’s ears while they sleep to lay eggs or burrow into the brain. This is completely false – earwigs have no interest in human ears and prefer dark, moist environments outdoors.

Why Earwigs Invade Mt. Juliet Homes

Middle Tennessee’s humid climate creates ideal conditions for earwigs, particularly during our warm, wet springs and the transition into fall. These insects seek three primary things:

Moisture: Earwigs require humid environments to survive, which is why they’re often found in bathrooms, kitchens, and basements. During dry spells or heavy rains, they may move indoors seeking optimal moisture levels.

Shelter: They prefer tight, dark spaces that mimic their natural hiding spots under bark, rocks, and leaf litter. Cracks in foundations, gaps under doors, and spaces around windows provide perfect entry points.

Food Sources: While primarily scavengers feeding on decaying plant matter, earwigs are omnivores that will eat living plants, other insects, and organic debris around your home.
