The adults are about 1 inch long, light brown with yellow margins on the region behind the head and the edge of the wings. The female has short wings and can not fly, the male’s wings cover the abdomen.

(Parcoblatta pennsylvanica) Woods cockroaches live in rotted logs, tree stumps, hollow trees, and under the loose bark of standing trees and firewood. The males fly to lights at night, and may be seen on windows and screens in the spring and fall. The females remain at the breeding site.

This cockroach does not infest structures, and there is no need for an extensive control program if a few are seen indoors. Removing breeding sites such as woodpiles and standing dead trees may help reduce the incidence.
