Pillbugs in Bristol

As one of the only crustaceans adapted to live on land, pillbugs are common throughout the United States. Pillbugs and sowbugs are similar-looking pests that are more closely related to shrimp and crayfish than to insects. Often known as roly-polies, pillbugs are able to roll up into a tight ball when disturbed or threatened. They are easily recognized by their back, which is made up of seven hard individual plates. Since pillbugs require moisture, they do not survive indoors for more than a few days unless there are very moist or damp conditions.

Pillbug Habitat

Pillbugs thrive in moist environments and can be found outdoors under mulch, fallen leaves, and rocks. Pillbugs are nocturnal and require humid conditions during the day. These crustaceans are generally found in moist soil along with sowbugs, millipedes, and earthworms. Pillbugs may leave their natural habitats at night and crawl about over sidewalks, patios, and foundations. They can become a nuisance as they often invade crawl spaces, damp basements, and first floors of structures at ground level.

Pillbug Behaviors & Dangers

Pillbugs are not too dangerous a pest. They do not bite, sting, or transmit disease. They are thus mainly a nuisance pest, especially when they venture indoors. They are capable of feeding on tender plant tissue and occasionally cause considerable damage to garden transplants and seedlings. Pillbugs typically enter buildings through door thresholds, especially homes with sliding glass doors on the ground level. Seeing a pillbug in the home is indicative of a large population of them outside your Tennessee property.
