Roaches can spread a variety of diseases and the dust created by cockroach skins, dead bodies and droppings can aggravate asthma and allergies.

German Cockroaches

About the same size as brown-banded roaches, the German cockroaches have two brown stripes running the length of their wings. Because they love fermented foods, they are regularly found in unsanitary kitchen or bathroom conditions.

Oriental Cockroaches

Dark brown and about one-inch long, oriental cockroaches seek out warm damp areas indoors. They flourish in basements and storage areas where they can stay close to the ground. They eat decaying organic matter and prefer starches.

American Cockroaches

Usually between 1 to 1½ inches long with reddish-brown wings, American cockroaches like to fly outside. They are scavengers with a special taste for warm damp places, water and alcoholic beverages. They like to eat decaying organic matter.

Brown-Banded Cockroaches

Often mistaken for German cockroaches, brown-banded roaches have golden stripes across their wings. These roaches are normally a little over a half-inch long and prefer to live in dry environments. Many of them like to set up shop inside of furniture and walls, feeding on starches.

Smokey-Brown Cockroaches

Generally over 1-inch long at maturity, Smokey-brown cockroaches live outside feeding primarily on plant matter. In flight at night, they fly toward sources of light.
