German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Alviso's a mild, dry-summer Mediterranean climate with the region's famous fog shaping local weather patterns keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Older established neighborhoods sit alongside significant new high-density development driven by the area's tech-fueled growth.
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.
