American Cockroaches are about 1-3/8" to 2-1/8" in length. They are reddish brown with a pale brown to yellowish band around their head. They have wings that extend the whole body length and are poor to moderately good fliers. This cockroach thrives in warm, damp environments such as sewers, drains, steam tunnels, basements, crawl spaces, and boiler rooms. They also gather together in open spaces while other domestic cockroaches tend to hid in cracks and crevices. They do enjoy sweet foods, but prefer decaying material.
Brown Banded Cockroach
Brown Banded Cockroaches are about ½" long. They are light brown to brown and females are darker than males. These cockroaches are nocturnal and both male and female have wings. However, males readily fly but the females cannot. They may be found throughout any structure, but they prefer dry, warm areas at high locations and inside furniture. True to their name, Brown Banded Cockroaches have two brown bands that run across their abdomens. The brown bands are visible in every stage of the roaches' life cycle.
German Cockroaches are about 1/2" to 5/8" long. They are light brown to tan except for two dark, almost parallel stripes on the pronotal shield. They are winged insects that rarely glide or fly. In homes, this pest will first locate itself in kitchens and bathrooms, as close as possible to food and moisture sources. It spends about 80% of its time resting in cracks and voids. German Cockroach populations tend to grow rapidly and require professional treatment.
Oriental Cockroaches are 1" to 1 ¼" long. They are usually black but may vary to a dark reddish brown and they are very shiny. They are winged insects but the adults do not fly. These cockroaches prefer cool, damp locations so they are typically located in basements and cellars. Often seen crawling around service ducts, toilets, bathtubs, sinks, radiators, and pipes. It is also known as the Water Bug.
Wood Cockroaches are about 3/4" to 1 1/4" long. They are dark brown with a translucent stripe on the outer edge of the thorax. Males are good fliers while the females do not fly because they are wingless. This species of cockroach is very different than other cockroaches that feed on filth, human food, and other human products indoors where poor sanitation is a contributing factor of infestations. Wood cockroaches feed on organic material and smaller insects outdoors. They live outdoors under the bark of dead trees, decaying logs, and other moist locations. They can also live under wood shingles. They do not live indoors but they are attracted to lights and can crawl inside through window frames, but are considered accidental invaders. Since they do not live indoors it is not necessary for pest control inside. Outdoor sprays are more effective for treatment and can help reduce the number that accidentally wander indoors.
