Cockroaches need three things to establish a colony: food, water, and warmth. Schaumburg's housing stock gives them exactly that. A blend of dense urban multi-family buildings and single-family suburban homes, nearly all with basements given the region's cold winters. Combined with Schaumburg's climate — a humid continental climate with hot, humid summers, cold and often harsh winters, and significant lake-effect influence near Lake Michigan — 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.
