About
The pill bug, sometimes referred to as “rollie pollies”, is the only crustacean that has become completely adapted to spending its life on land. This pest earned its nickname due to the fact that the pill bug can roll up into a tight ball when disturbed. Pill bugs live around the world and Armadillidium vulgare is the most common species in the U.S.
Pill bugs are between ¼-5/8 inches long and have seven pairs of legs and 2 pairs of antennae. Rollie pollies are usually slate gray in color. Their bodies are oval shaped and become round when they roll up. They are easily recognized by their back, which is made up of seven hard individual plates.
Pill bugs typically enter buildings through door thresholds, especially homes with sliding-glass doors on the ground level. Seeing a pill bug in the home usually means that there is a large population outdoors. Pill bugs do not survive more than a few days indoors without moist conditions and a food supply.
