Cockroaches need three things to establish a colony: food, water, and warmth. Montchanin's housing stock gives them exactly that. Established suburban neighborhoods with basements dominate here, ranging from post-war construction to more recent development. Combined with Montchanin's climate — a climate shaped by Delaware Bay and Piedmont terrain, with cold winters and humid summers — 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.
