Oriental cockroaches are the largest of the common cockroaches, measuring 1 to 1.5 inches long. They are black or dark brown and have shiny, dark-colored bodies. They are most easily identified by their large size and their smooth, dark head.
Oriental cockroaches are common in the United States and Canada. They are most commonly found in basements, crawl spaces, and other damp, dark areas. They can also be brought into your home on food or garbage. They are most common in the spring and can travel through floor drains.
The best way to get rid of oriental cockroaches is to eliminate their hiding places by getting rid of any clutter and cleaning up any spills and moisture. You can also use commercial cockroach bait or spray. If you have a severe infestation, you may need to call a professional exterminator.
