These arthropods are identified by their semicircular shape and numerous legs-they have two legs per body segment (often called ‘thousand leggers’). Their size varies from a half to two inches, and their color varies from brown to brown and yellow. They roll into a ball when disturbed. 

Removing accumulations of decaying vegetation and excess mulch will eliminate potential breeding sites for these arthropods. Chemical control is difficult because they may not be easily killed with insecticides.
