German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Key Biscayne's one of the most consistently hot and humid climates in the continental U.S., with a wet summer season and a milder, drier winter keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Slab-on-grade concrete-block homes dominate, built to hurricane code, with minimal need for winter-focused design.
Because sanitation and moisture are almost always part of the problem, our process pairs targeted gel-bait treatment with a review of what's drawing roaches in — a leak, exposed food storage, cluttered voids. Broadcast sprays just scatter a colony; bait placed at the harborage site eliminates it. A follow-up visit confirms results.
