Cockroaches need three things to establish a colony: food, water, and warmth. Highlandville's housing stock gives them exactly that. A blend of established hill-country homes and newer suburban growth tied to Springfield's regional hub status. Combined with Highlandville's climate — a humid subtropical-leaning climate with hot, humid summers and milder winters than the rest of Missouri, given the region's more southern position — 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.
