Sowbugs and pillbugs

Sowbugs and pillbugs are less than 2 cm long and are usually dark to slate gray. They are armadillo-like and belong to the same class of animals as lobsters and shrimp. These tiny land crustaceans need moist conditions to survive, and like to live under rocks or debris where they feed on decaying organic matter. They usually die quickly once inside homes because moisture levels are not high enough for them.
