American cockroaches are capable of flying but rarely do in northern areas of the United States. When indoors, the nymphs and adults are usually found in dark, warm and moist areas of basements and crawl spaces, and in and around bathtubs, clothes hampers, floor drains, pipe chases, and sewers. They are also common around the manholes of sewers, and on the undersides of metal covers over large sump pumps.
• American cockroaches are one of largest species of cockroach that invade homes.
• Adults are about 1-1/2 inches long and reddish brown.
• The wings of the male extend farther beyond the tip of the abdomen than those of the female, though both can fly.
