Sowbugs (rolly pollys), pillbugs, millipedes, and centipedes occasionally enter the house. However, they prefer moist areas near the top of the soil in mulched flower beds, leaf litter, grass clippings and other debris around foundations, rocks, boards etc. Cracks between slabs, porches and in basement walls provide excellent cover.
Sanitation is the first step. Remove vegetation and other organic matter (rotting wood, clippings, etc.) from the surface of the soil in a strip 3 feet wide around the foundation. This barrier will help prevent sowbugs, pillbugs, millipedes and centipedes from entering the home. Make the basement, foundation, and entrances to the first floor of homes as tight as possible. Use caulking compound to fill cracks around doors, basement windows, and other openings large enough for the pests to pass through. Repair cracks in the foundation and basement walls.
