Norway rats (rattus norvegicus) are one of the most common species of rats in the world. They are also known as brown rats, sewer rats, or simply “common rats.” Norway rats live alongside humans and are especially troublesome in urban environments. Good rat prevention and control measures are essential to keep these pests away from your home.

Identifying Norway Rats

Norway rats can be either gray or brown in color and tend to have lighter undersides. They also have small ears and blunt noses. They are larger than most rat species, weighing up to 18 ounces. An important identifying characteristic that can help you distinguish Norway rats from their smaller cousin, the roof rat (AKA black rat) is the length of the tail. Roof rats have tails that are longer than the combined length of their head and body. Norway rats have tails that are shorter than the head and body length, which can be around 11 inches long.
