The Sowbug, also known as the pill bug or rolly polly, are all isopodic crustaceans. They are also known as woodlouse. Though these bugs are typically regarded as beneficial in gardens just like earthworms, some feed on cultivated plants such as strawberries or young seedlings. They have also been known to invade homes in search of moisture. They do not physically damage property, but their presence can indicate property in need of inspection for moisture damage. Burns can advise you on best practices to keep these bugs in the garden where they belong.
