Cockroaches need three things to establish a colony: food, water, and warmth. Bloomfield Hills's housing stock gives them exactly that. Older brick and wood-frame homes built during the region's auto-manufacturing boom, most with basements to handle harsh winters. Combined with Bloomfield Hills's climate — a four-season climate typical of the Great Lakes region, with real winter cold and consistent summer humidity — 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.
