German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Fleetville's a four-season climate typical of the Pennsylvania mountains, with more snow than the Philadelphia area keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Historic rowhomes and twin homes from the coal and industrial era, alongside newer construction in the Lehigh Valley's logistics 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.
