Cockroaches need three things to establish a colony: food, water, and warmth. Dickerson's housing stock gives them exactly that. Dense rowhouse and multi-family housing in the urban core, alongside single-family suburban homes further out, most with basements. Combined with Dickerson's climate — a four-season climate with real winter cold and snow, and hot, muggy summers — 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.
