Problem: Sowbugs and Pillbugs
Sowbugs and pillbugs are crustaceans related to lobsters and shrimp. They are dark brownish gray, with hard, flattened, segmented bodies about 1/2 inch long, and have legs; pillbugs roll up into a ball when disturbed. Both bugs are nocturnal insects, feeding at night on decaying vegetable matter. During the day, they hide in damp, dark places: under boards, rocks, or flower pots, or in plant debris. The bugs require damp places with high humidity and cannot live in dry areas. Sometimes they enter homes through cracks or windows, hiding in basements or other dark places. In late summer or fall, large numbers may invade homes in search of somewhere to overwinter. They occasionally wander into homes in spring or summer. They do no damage inside but can be a nuisance.
Prevent more from entering by sealing foundation cracks and putting weatherstripping under doors. Eliminate moist, dark breeding sites such as nearby boards, and storage boxes. If the bugs persist in the house, check for leaks or dampness and fix the problem.
