Cockroaches need three things to establish a colony: food, water, and warmth. Dewitt's housing stock gives them exactly that. Housing here dates heavily to the early-to-mid-1900s auto-industry era, with established neighborhoods and full basements standard. Combined with Dewitt's climate — a climate shaped by the region's Great Lakes position, somewhat milder in winter than western Michigan's snowbelt — indoor cockroach pressure rarely lets up on its own.
We start with an inspection to identify the species and the source — sanitation issue, moisture problem, or entry point. Treatment centers on gel bait placed in cracks, voids, and under appliances, not broadcast spraying, since German cockroaches in particular have developed resistance to many surface sprays. A follow-up visit confirms the bait is working and the population is dropping.
