Oriental Cockroach

Oriental Cockroaches in Wisconsin

The oriental cockroach is often referred to as the “black beetle” or “water bug” and is a major household pest in parts of the northwest, mid-west, and the southern United States. This species is attracted to wet and shady perimeter areas and prefers the dark and dampness of basements, cellars, and crawl spaces. Oriental cockroaches are known to climb water pipes and garbage chutes to access the upper floors of apartment buildings. They feed on all kinds of filth, debris, and other decaying organic matter and seem especially fond of garbage and the contents of discarded tin cans.

Oriental Cockroach Habitat

Oriental cockroaches are common outdoors and live in warm, damp shady areas near the ground. Outside the house, these cockroaches will gather near or under trash cans. When temperatures drop, they may seek shelter indoors but can tolerate cooler weather. Oriental cockroaches may enter homes in food packages from grocery stores or gain access under exterior doors, garage doors, air ducts, and ventilators. Inside, they tend to remain on lower floors and move more slowly than other species. The most common areas to find oriental cockroaches in homes are toilets, bathtubs, sinks, radiators, and pipes. These cockroaches are seasonal and adults generally appear from May through July.
