It has an average length around 4 cm (1.6 in) and is about 7 mm (0.28 in) tall. They are reddish brown and have a yellowish margin on the pronotum, the body region behind the head. Immature cockroaches resemble adults except they are wingless.

The cockroach is divided into three sections; the body is flattened and broadly oval, with a shield-like pronotum covering its head. A pronotum is a plate-like structure that covers all or part of the dorsal surface of the thorax of certain insects. They also have chewing mouth parts, long, segmented antennae, and leathery fore wings with delicate hind wings. The third section of the cockroach is the abdomen

The truth is however that roaches are mostly a beneficial pest when they are outside. 5 out of the 6 roaches found locally in DFW are primarily outside dwelling roaches. There is one roach however that has adapted to live off the waste/trash that humans create or make, and that’s the German Cockroach. When a pest has adapted to live off human these types of pests are called commensal pest, meaning they live off us/humans. Bed bugs would be another great example of a commensal pest.
