630:. Brought indoors on infested firewood, they wander about the house without congregating in any particular room. They can be especially troublesome during the mating season, which is during May and June. Male wood cockroaches frequently travel in large numbers and fly considerable distances. They are attracted to lights at night and may gain entry indoors. Large numbers may also be found in rain gutters of homes.
761:
Houses located within woods will sometimes have wood cockroaches crawl under siding; especially homes with cedar shake shingles. To cockroaches, the house may represent a fallen tree and a new location for nesting. A wide lawn will inhibit cockroaches crawling from the surrounding woods to the house.

The
Pennsylvania wood cockroach has three developmental stages: egg, nymph, and adult. Eggs are laid in egg capsules, produced during the warm months and deposited behind the loose bark of dead trees, fallen logs, or stumps. Egg capsules are yellowish brown and characteristically curved on both sides

Pennsylvania wood cockroaches feed primarily on decaying organic matter. Both female and male
Pennsylvania wood cockroaches have been found under shingles and on the inside of garages. They rarely breed indoors. However, with the growing use of firewood, the popularity of cedar shake shingles, and

Ontario and Quebec, and the eastern and central United States, in Alabama, the District of Columbia, probably Florida, Delaware, Georgia, Virginia, Illinois, Indiana, Iowa, Kansas, Louisiana, Massachusetts, Maine,

like a half moon. Capsules are twice as long as wide, each containing up to 32 eggs. The egg stage lasts about 34 days at 80 °F, while the nymphal stage typically lasts 10 to 12 months but can last up to 2 years. The normal life span of the female adult is several months.
846:
Exterior treatments to foundations, around doors and windows, porches, patios and other areas where outside lights are located will help control both the adult males (which will fly to the lights) and the females (which crawl to the house in search of harborage).

621:
The species occurs in open, timbered areas with little ground cover. According to entomologist Fred A. Lawson, it is "often seen on tree trunks and lower branches of oaks and elms after dark." Nymphs and adults are also found outdoors beneath loose

Pennsylvania wood cockroaches are most often carried into homes under the bark of firewood. It is best to not store firewood inside the house. Move woodpiles away from the house to further reduce the likelihood of cockroaches wandering in.
539:
Males are dark brown; the sides of the thorax and the front half of the wings are margined with yellow. Adult males are fully winged, while females have conspicuous wing pads (actually short wings like that of the female

As breeding populations rarely become established indoors, house interiors should not be treated. Treat exteriors only when wood cockroaches enter homes from the surrounding environment.

The species frequently invades summer cottages, and while it is considered a nuisance, it is rarely in enough numbers to be considered a pest.
