Earwigs are one of those pests that cause a lot of alarm but aren’t actually dangerous. Those rear pincers look threatening — they’re not. But that doesn’t mean you want them in your Carter Lake home. Earwigs can invade in large numbers during wet Iowa springs and dry summers, pushing inside through foundation gaps and basement-level entry points. A few earwigs outside in the mulch is normal. A few dozen in your basement or bathroom is a problem worth addressing.

Signs of an Earwig Infestation

Earwigs aren’t shy about being seen, especially at night. Common signs include:

  • Live earwigs indoors — often found in basements, bathrooms, laundry rooms, or crawl spaces where moisture is present
  • Large numbers outside under mulch, leaf litter, landscape timbers, or rocks near the foundation
  • Chewed plant material — ragged holes in leaves, seedlings, or garden plants near the foundation
  • Earwigs in stored items — newspapers, cardboard boxes, or cluttered areas in the basement
  • Entry points at ground level — gaps around utility pipes, foundation cracks, and under door sweeps

Why Earwigs Are Common in Carter Lake

Iowa’s climate works in earwigs’ favor. They need cool, moist hiding spots during the day and feed at night. The combination of summer humidity, frequent spring rains, and the mulched landscaping around most Carter Lake homes gives them exactly what they want — a comfortable outdoor habitat just a few feet from your foundation.

When summer turns unusually dry, earwigs move inward looking for moisture. When spring is especially wet, they reproduce explosively in the yard and then overflow into crawl spaces and basements. Either way, Carter Lake homeowners often see earwig activity in waves rather than at a consistent low level.

Older homes in Carter Lake with block foundations or gaps around aging utility penetrations are especially vulnerable. Earwigs don’t need a large opening to get inside.

Our Earwig Control Process

Miller Pest Solutions uses exterior perimeter barrier treatments as the primary tool for earwig control — combined with targeted interior treatments when earwigs have already made it inside.

  • Exterior assessment to identify harborage areas: mulch beds, landscape timbers, wood piles, dense ground cover near the foundation
  • Perimeter barrier treatment along the foundation, around entry points, and through mulch/landscape beds where earwigs are concentrated
  • Foundation-level crack and crevice treatment to address active entry points
  • Interior treatment of basements, crawl spaces, and other moist areas if earwigs have already established inside
  • Harborage reduction recommendations — moving mulch away from the foundation, reducing debris piles, improving drainage

The goal is always to stop earwigs at the perimeter before they make it inside. Interior earwig activity is almost always a sign of heavy outdoor pressure combined with a gap in the building envelope.
