Norway rats live in close association with people. They live in and around residences, in cellars, warehouses, stores, slaughterhouses, docks, and in sewers. On farms, they may inhabit barns, granaries, livestock buildings, silos, and kennels. Norway rats will eat nearly any type of food. Norway rats are primarily nocturnal. They usually become active about dusk, when they begin to seek food and water. They can cause structural damage to buildings by burrowing and gnawing, transmit diseases, and contaminate food.
