German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Locust Gap's a climate shaped by the Susquehanna Valley, somewhat milder in winter than the mountains to the north keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Stone and brick farmhouses are common throughout this region, alongside newer subdivisions near the capital corridor.
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.
