Identification

Crustaceans in Your Basement

Sowbugs and pillbugs are technically crustaceans (not insects) oval, segmented, grey-brown arthropods about 12mm long. Pillbugs roll into a ball when disturbed; sowbugs cannot. Both live outdoors under stones, logs, and leaf litter feeding on decaying plant matter. They enter homes through foundation gaps, door thresholds, and basement windows, always following moisture.

Signs of Infestation

Signs of infestation:

  • Grey, oval bugs found in basement, bathroom, or near ground-level entry points
  • Large numbers appearing after rain
  • Activity under door thresholds, along basement walls, or near floor drains
  • Found in flower pots or houseplant soil
  • Dead sowbugs in basement corners
Health & Safety

Harmless Nuisance Pest

Sowbugs and pillbugs are completely harmless to humans and pets they don't bite, sting, or spread disease. Their presence in large numbers is a reliable indicator of excess moisture around the foundation and entry points that need addressing. They also damage seedlings and tender plants in greenhouses and indoor gardens.

Our Treatment

Foundation Treatment & Moisture Control

We apply targeted perimeter treatment to the foundation, entry points, and moisture-prone areas. More importantly, we advise on the moisture and debris conditions attracting them improving drainage and removing leaf litter from the foundation significantly reduces populations over time.
