Pillbugs and Sowbugs
The sowbug possess two tail-like appendages at the tip of the abdomen and are incapable of rolling into a tight ball. The common pillbug lacks such appendages at the tip of the abdomen and can roll itself into a ball. This habit is the reason they are often called “roly polies”.
Both pillbugs and sowbugs feed upon decaying vegetable matter.
Are found under mulch or vegetable debris of all kinds and beneath objects on damp ground. They frequently invade damp basements and crawl spaces and may infest potted plants. A heavy infestation indoors generally indicates that there is a large population immediately outside the building.
Pillbug and Sowbug Management:
Pillbugs/sowbugs feed and reproduce in decaying organic matter, so it may be necessary to remove plant mulch and leaves around the foundation in order to obtain control.
