Cockroaches need three things to establish a colony: food, water, and warmth. Darien's housing stock gives them exactly that. A blend of historic shoreline towns and newer suburban development, nearly all built with basements for the region's cold winters. Combined with Darien's climate — a humid continental climate moderated by Long Island Sound, with cold winters and warm, humid summers — indoor cockroach pressure rarely lets up on its own.
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.
