Sowbugs look similar to pillbugs and have oval bodies that are flattened and have two small appendages in the rear that look like tails. Sowbugs cannot roll up like pillbugs do when they are disturbed. They commonly found under mulch in flowerbeds, as the eat decaying plants and organic debris.

Sowbugs need moisture to survive, so they can be found indoors in damp garages, basements, crawl spaces and cellars. Outside, they seek shelter in the soil, under rocks, flowerpots, trash cans, and logs. They are more active at night.


If the presence of sowbugs are in your home, it is an indication high moisture conditions. High moisture conditions also contribute to favorable breeding conditions for other insects, wood rot, and mildew. Pay attention to the moisture and humidity levels in garages, basements, crawl spaces, and cellars.

Sowbugs gain entry into homes through ground-level doors, windows, and often sliding glass doors. Using proper weather stripping on doors and windows and eliminate moisture rich materials outdoors to reduce the chance for them to get indoors.
