German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Millers Creek's a humid subtropical climate in and around Charlotte and the coastal plain, cooler and more mountain-influenced around Asheville keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Crawl-space construction is common throughout this region, though mountain homes near Asheville often include basements for cooler, wetter conditions.
Because sanitation and moisture are almost always part of the problem, our process pairs targeted gel-bait treatment with a review of what's drawing roaches in — a leak, exposed food storage, cluttered voids. Broadcast sprays just scatter a colony; bait placed at the harborage site eliminates it. A follow-up visit confirms results.
