Because of their preference for sewers and heat tunnels, they are notable as a problem in urban commercial districts. They are seen in late May or June, especially after rains. This roach is often confused with both adult American and oriental roaches. However, the wood roach is chestnut brown and has a dull white band around the edges of the head and back. Females have wings covering only about half the body and do not fly.
Males have wings longer than the body and are excellent fliers.
Females produce about 30 egg capsules, each containing about 32 to 36 eggs. This roach completes one generation per year. Wood cockroaches are usually found in wood piles, hollow trees or under loose bark. Buildings in wooded areas are prone to have problems with wood roaches during rainy periods. Although this roach prefers to live outside, adult males are attracted to light and may enter buildings.
