Pillbug (or sowbug)


Oval shaped; round when rolled-up; look like tiny armadillos. Dark brown, grey or black; 3/4-inch.


Pillbugs (also known as sowbugs) live in moist locations, such as under damp objects or vegetable debris. When they find their way inside, they are usually found in damp basements, cellars and crawl spaces. Very often they die of dehydration after entering a home. Pillbugs do not spread disease or invade food products.


Pillbugs feed nocturnally on decaying vegetable matter.

Insect control: pillbugs

Seal exterior cracks and holes in your home’s foundation. Holes can be closed by stuffing pieces of wire mesh or screening into the openings. Remove thick ground cover such as ivy near or next to your foundation, as it provides a home for spiders, insects, mice and other pests. Store firewood and lumber off the ground and away from the building. Inside treatments is usually not necessary because pillbugs dry out quickly and die.
