Have a Pillbug Problem?


The Pillbug is actually not a bug but a crustacean that has adapted to living on land. It has an oval shaped body with a segmented, armor-like shell, two pairs of antennae and seven pairs of legs that are nearly hidden by its shell. Many people also call them “roly-polies” as their segmented shell allows them to roll up into a ball.

The Pillbug is often found in gardens, flowerbeds, flowerpots, mulch, and under decaying leaves, where it feeds on the decaying plant matter and animal waste. It is a scavenger and will eat live plants when necessary.

When large populations are present Pillbugs may move indoors in search of moisture and decaying organic matter. Numerous indoor sightings may indicate high moisture levels or water leaks. Pillbugs do not bite humans and do not carry diseases.

Pill bugs live in wet locations. They are found under damp objects or in organic garbage. If pill bugs enter a building, they will often dry out and die.

Control Advice

Relocate decaying leaf and wood away from the home. Keep mulch under 2 inches thick. Firewood should be stored off the ground and away from the home. Seal exterior openings to the home.

Active Seasons

The Pillbug is most active in spring.
