Cockroaches need three things to establish a colony: food, water, and warmth. Herrick's housing stock gives them exactly that. A mix of historic river-town homes, farmhouses, and government-corridor housing around Springfield, most with basements. Combined with Herrick's climate — a climate that behaves more like the upper South than northern Illinois, with shorter, milder winters — 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.
