American cockroaches



American cockroach (Blattaria: Blattidae, Periplaneta americana) adults are 1 and 1/2 inches long and are reddish brown and have a yellowish margin on the body region behind the head. When disturbed, may run rapidly and adults may fly. Immature cockroaches resemble adults except that they are wingless.

American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water. They prefer warm temperatures around 84 degrees Fahrenheit and do not tolerate cold temperatures. In residential areas, these cockroaches live in basements and sewers, and may move outdoors into yards during warm weather. They feed on a wide variety of plant and animal material.

Females produce egg cases and carry them protruding from the tip of the abdomen for about two days. Egg cases are then generally placed on a surface in a hidden location. Egg cases are 3/8 inch long, brown, and purse shaped. Immature cockroaches emerge from egg cases in 6 to 8 weeks and require 6 to 12 months to mature. Adult cockroaches can live up to one year.
