Cockroaches need three things to establish a colony: food, water, and warmth. McClelland's housing stock gives them exactly that. A blend of older river-valley homes and small-town construction typical of western Iowa. Combined with McClelland's climate — a humid continental climate with hot summers, cold winters, and somewhat drier conditions than eastern Iowa — 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.
