Norway rat


Gray, brown or black, with small eyes and ears and tails shorter than their bodies; up to 12 inches.


The Norway rat is the largest and most common structure-dwelling rat in the world. In rural areas it lives in fields, wooded areas and farms, and in urban areas in vacant lots and buildings, where it is a focus of rodent control. It nests in burrows underground and may enter buildings in search of food. Due to its large size, it needs a hole about the size of a quarter to enter a building. Once inside, Norway rats can chew through wiring, causing fires, and removing them often requires professional rodent control expertise. They are known to spread numerous diseases.


Norway rats will eat practically anything, although they prefer meat, fish and cereal.
