Pillbug

Pillbugs (1/4" - 3/8" long) are found in lawn turf, under leaves or other moist areas of decaying vegetable matter. Extremes of wet, dry or hot weather may drive them inside, where they do no damage, but are an annoyance. Pillbugs roll into a ball or "pill" when they are disturbed. Keeping mulch to a layer no thicker than 2 inches and cleaning up leaf litter is the key to long term prevention of this pest.
