German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Willcox's a Sonoran Desert climate moderated by elevation, with warm days, cool nights, and a monsoon season that reshapes pest activity every summer keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing here ranges from traditional adobe-and-block homes in town to manufactured housing and newer stucco construction on larger rural lots.
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.
