Norway rats are heavy-bodied rats with blunt noses and shorter tails. They tend to burrow along foundations, under concrete slabs, and around sheds. Indoors, they show up in crawl spaces, utility rooms, and lower levels. You might notice gnaw marks, greasy rub marks along walls, and large droppings.

Rats can damage insulation, chew wiring, and contaminate food and storage areas. A small rat problem rarely stays small. BRD uses a combination of baiting, trapping, and structural recommendations to remove active rats and shut down the routes and harborages that allowed them in.
