Cockroaches need three things to establish a colony: food, water, and warmth. Rowland's housing stock gives them exactly that. Crawl-space construction is common throughout this region, though mountain homes near Asheville often include basements for cooler, wetter conditions. Combined with Rowland's climate — a humid subtropical climate in and around Charlotte and the coastal plain, cooler and more mountain-influenced around Asheville — 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.
