Pillbugs (sometimes referred to as woodbugs) are less than 2 cm (.79 inches) long and are usually dark to slate gray. They are armadillo-like and belong to the same class of animals as lobsters and shrimps. These tiny land crustaceans need moist conditions to survive, and like to live under rocks or debris where they feed on decaying organic matter.

Pill bugs don’t bite or sting people. They are annoying but harmless. Pill bugs will eat plant material and animals in the process of decaying. Pill bugs enter properties through ground level access points, including garages. They won’t lay eggs inside or damage any household items. They usually die quickly once inside homes because moisture levels are not high enough for them.
