German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Berrysburg's a humid continental climate with hot, humid summers and cold winters, moderated slightly by the region's lower elevation valleys keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A blend of historic farm country homes and government-corridor suburban growth around Harrisburg.
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.
