Wood Cockroach Male
CHARACTERISTICS
Size: Color:
A number of species belong in this group. Adults measure 1/2-inch to one inch in length. Reddish brown to dark brown, depending on the species. Females do not have fully developed wings, only small wing pads.

Behaviour
This species lives primarily outdoors and is considered a nuisance pest, as it does not breed inside homes. Adult males usually mature in June and July and are active at night. Being strong fliers, they will readily fly to lights on buildings and may crawl inside. Where conditions exist to support adult females and nymphs close to a home foundation, these may wander inside occasionally throughout the summer.

Habitat
Changing exterior lighting to yellow "bug" lights can help reduce the number of cockroaches attracted to a home, as can simply keeping lights turned off. It is also important to seal as many exterior cracks as possible, and to ensure that all foundation and attic vents have tight-fitting screens. Removing leaf piles, woodpiles and other harborages is very important in minimizing the potential number of cockroaches near the home.
