German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and South Berwick's a coastal climate moderated by the Gulf of Maine, with cold winters and cool, pleasant summers keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A blend of historic coastal architecture and newer development, with basements standard given the cold winters.
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.
