Cockroaches need three things to establish a colony: food, water, and warmth. Mascoutah's housing stock gives them exactly that. A blend of established farm-country homes and newer suburban growth closer to the St. Louis metro area. Combined with Mascoutah's climate — a humid continental climate with hot, humid summers and milder winters than the rest of the state, warmer overall the farther south you go — 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.
