German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Mesopotamia's a humid continental climate with heavy lake-effect snowfall off Lake Erie and warm, humid summers keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Wood-frame and brick construction from the industrial era dominates, built to handle the region's severe winters.
Because sanitation and moisture are almost always part of the problem, our process pairs targeted gel-bait treatment with a review of what's drawing roaches in — a leak, exposed food storage, cluttered voids. Broadcast sprays just scatter a colony; bait placed at the harborage site eliminates it. A follow-up visit confirms results.
