What is a Oriental Cockroach?

The origin of the oriental cockroach, Blatta orientalis Linnaeus, is uncertain, but it is thought to be from Africa or south Russia. It is a major household pest in parts of the northwest, mid-west, and southern United States. It is also sometimes referred to as the "black beetle" or a "water bug" because of its dark black appearance and tendency to harbor in damp locations.

What do they look like?

The oriental cockroach is approximately 1 inch long (22 to 27mm) and dark brown to black. Males have wings covering 3/4 of their body, and the female has very short (rudimentary) wings. The inner wing folds like a fan and is membranous. The outer part of the wing is narrow, leathery and thick. The styli between a pair of jointed cerci can identify the male. Both the male and female are flightless.

What are signs of an Oriental Cockroach infestation?

Oriental cockroaches are mostly active at night when they are foraging for food and water. During the day they will hide in cracks and crevices in walls and through the home or business they are infesting. If there is a heavy population you may see them scurrying around or even flying about during the day when disturbed. You may also find their feces in kitchen areas inside the drawers and cabinets, behind appliances and in basements, their excrement resembling coffee grounds. They also secrete an odor that may cause a musty smell in the area they are infesting.


Where will you find Oriental Cockroaches?

Any area that has a high humidity and a cool temperature should be examined. Crawl spaces, basements, and kitchen and bathroom plumbing can be inspected for dead roaches, egg cases, and fecal smears. Also, any spider webs in these locations can be inspected for cockroach remains.
