German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Iselin's a humid climate with a long summer season and coastal-moderated winters keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A blend of historic river-town construction, coastal shore homes built for salt air and storms, and rural south Jersey farmhouses.
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.
