Cockroaches
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. When disturbed they run rapidly and adults may fly. 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. The oriental cockroach is a pest in homes throughout much of the United States. During the summer, oriental cockroaches move outdoors where they may venture into neighboring buildings. It commonly 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.
German Cockroach – The German Cockroach is about ½" in length and can be easily recognized by the two dark, longitudinal stripes on the "shield" at the front of the body under which the head is located. The German cockroach is the most prolific breeder among all cockroaches and like all cockroaches; it is omnivorous and will eat virtually anything. This pest will first locate itself in bathrooms and the kitchen, as close as possible to food and moisture sources and then spread throughout a home or building as the population grows. During its life it will spend about 80 percent of its time resting in cracks and voids.
