Cockroaches need three things to establish a colony: food, water, and warmth. Roscommon's housing stock gives them exactly that. Wood-frame and brick construction from the manufacturing era dominates, alongside newer suburban development further out. Combined with Roscommon's climate — a humid continental climate with hot, humid summers, cold winters, and moderate lake-effect influence from Lake Huron and Lake Erie — 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.
