German cockroach (Blattella germanica)

Cockroaches generally have a flattened, oval appearance, long spiny legs and long antennae. Color, which depends on species and age, ranges from a reddish brown to dark brown and from tan to black. The German cockroach (pictured at right) is by far the most likely species to infest homes in Maine. It is about 1/2 inch long, light brown, with two lengthwise black stripes on the shield behind its head. The adults are fully winged, but rarely fly. The nymphs resemble the adults but are smaller, darker and wingless.

Due to its size (up to 2″ long), the American cockroach is the species most likely to be recognized in Maine (see link and first photo below). American cockroaches may be found in any room of the house.

Although cockroaches carry disease organisms, they are not known to transmit disease to humans. They do contaminate food and kitchen utensils with excrement and salivary secretions, leaving an unpleasant odor.
