American Cockroach -The American Cockroach is among the largest of all cockroaches with adults ranging between 1?- 1 1/2? They are reddish brown and have a yellowish margin on the body region behind the head. American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water. They prefer warm temperatures and do not tolerate cold temperatures well. In residential areas, these cockroaches live in basements and sewers, and may move outdoors into yards during warm weather. Like all cockroaches, they are omnivorous and will eat virtually anything.
Oriental Cockroach -The Oriental Cockroach or “water bug” is about 1? in length. The female is entirely black, while the male is black with two brown wings. This difference in appearance often leads homeowners to believe they have two different types of cockroaches. During the summer, oriental cockroaches move outdoors where they may venture into neighboring buildings. It inhabits sewers and storm culverts and will enter buildings through floor drains. During the colder months, they invade homes, establishing themselves in basements and crawl spaces. This cockroach can be a public health concern because they have been known to carry Salmonella bacteria-the organisms responsible for food poisoning.
