German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Harrells's a climate shaped by elevation and coastal proximity, warm and humid in the Piedmont and coast, cooler and wetter in the mountains keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing here ranges from newer Charlotte metro subdivisions to historic mountain cabins to coastal farmhouses.
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.
