Like Pillbugs, they can be found under stones, large rocks, logs, leaf litter, compost, mulch and wood stacks. In fact, another name for a Sowbug is Woodlouse (plural Woodlice). They scavenge for decomposing organic debris in these areas. It is not unusual to see a few under the same stone or log, all searching for food. They prefer moist areas and will head toward darker, more humid areas if displaced. Infestations are not likely and they are not considered a nuisance. If any find their way indoors, they are unlikely to live long unless they find a damp, cool place. Removing debris and maintaining a dry interior will reduce the likelihood of seeing them inside.
