German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Hildebran'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.
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.
