This is primarily an outdoor roach species that looks very similar to the German roach. It differs in that it flies readily and is attracted to lights and light-colored surfaces. Outdoors it may breed in huge numbers, and readily invades structures as well, although it generally does not breed within a structure. Outdoors it can be very common in shaded areas of thick vegetation, such as wooded areas or thick grassy habitats. There are estimates of up to 100,000 individuals per acre being found.
Control efforts with pesticides will have limited results, since the roaches often originate in wooded or grassy areas beyond the customer’s property where treatments cannot be made. They may fly well over 100 feet in a single flight, coming to structures and the lights on them, easily bypassing chemical barrier treatments. Reduction of harborage sites and elimination of attractive lighting are encouraged.
