Oriental cockroaches are believed to be of North African origin, despite their name. Oriental roaches are sometimes called “waterbugs” because they come out of drains, and “black beetle cockroaches” because of their smooth, dark bodies. They are known for their strong, unpleasant, “roachy” odor.
The Oriental cockroach feeds on all kinds of food, especially decaying organic matter and starchy foods. This species of cockroach can survive outdoors in freezing temperatures for long periods of time.
Outside, Oriental cockroaches are often found in sewers and under debris, leaves, stones and firewood. They will enter structures through door thresholds, under sliding glass doors, along utility pipes and through floor drains. Once indoors, Oriental cockroaches find harborage in basements and crawl spaces.
