Pill bugs, sometimes called “Rollie Pollies” because of their tendency to roll into a ball, are actually crustaceans and breathe through a pair of gills. Moisture is vital to their survival so they are often found in damp soil and gardens. They dine on soft roots, leaves, seedlings and decaying plant material. They enter the home through doors and other ground level entrances. Damp basements and homes with a lot of moisture can be a cozy place for pill bugs. Fortunately, they do not bite or carry disease, but can be troublesome to the homeowner when they enter the home or damage plants.
