Behavior and Habitat of Norway Rats
Norway rats will eat nearly any type of food, but they prefer high-quality foods such as meat and fresh grains. Contrary to mice, rats need a free-standing water source in order to survive, as they do not get the moisture needed from their food source alone. Norway rats have a keen sense of taste, hearing, and smell, but have bad eyesight. Norway rats live in close association with people. They burrow to make nests under buildings and other structures, beneath concrete slabs, around ponds, in garbage dumps, and at other locations where suitable food, water, and shelter are present. Although they can climb, Norway rats tend to inhabit the lower floors of multi-story buildings, as well as sewers.
Signs of Infestation of Norway Rats
Outdoor burrows surrounding the building may be an indication of Norway rat nesting. Look for gnaw marks on food and objects, rub marks or grease stains, and droppings.
Tips for Prevention of Norway Rats
Seal any holes on the outside of the home that are larger than 1/2" with silicone caulk, cement, wire mesh, steel wool, or foam, and eliminate sources of moisture, especially in crawl spaces.
