American Cockroach


The American cockroach can gain access via drains, coming up through sewer systems. It’s much more common in restaurants, bakeries, grocery stores food-processing plants and hospitals than it is in residences. The American cockroach is not only a nuisance but has been known to be a vector (disease carrier). Its favorite food is the fermenting kind, like rotting fruits and vegetables.


Controlling cockroaches comes down to exclusion – preventing them from entering by blocking potential entry points, and inspecting what you bring into your house for roaches or egg casings. Good sanitation is also important: Clean up food and water that could attract roaches, and reduce their harborage by eliminating clutter. If you think you have a roach problem, your Clark technician can determine the best course of action to remove them from your environment.
