German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Woodside's a coastal climate milder in winter than northern Delaware, with hot, humid beach-town summers keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A mix of beach cottages, newer coastal construction, and farmhouses on the flat Delmarva farmland, many built on crawl spaces given the high water table.
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.
