German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Dearborn's a climate shaped by the region's Great Lakes position, somewhat milder in winter than western Michigan's snowbelt keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing here dates heavily to the early-to-mid-1900s auto-industry era, with established neighborhoods and full basements standard.
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.
