The five cockroaches listed above are the ones we commonly see in the Midwest. Each requires a different method of control due to different habits. Identification and location of the harborage is the first step. Next, sanitation and removal of food sources needs to be addressed. Low odor, low toxicity gel baits will kill the roaches and leave them unable to reproduce. Professional treatment to identify, locate, and treat the problem can be done with little disturbance to the occupants of the home
