What is the most common rat found in America?

The most common rat found in America is indeed the Norway Rat. This species is highly adaptable and typically thrives in urban and rural environments. Known for its robust physique, the Norway Rat is characterized by its brown fur, a bulkier body, and a shorter tail compared to other rat species. It often nests in burrows or underground areas, making it a common sight in sewers and basements.

Norway Rats are not only prevalent in populated areas due to their ability to scavenge for food, but they also reproduce rapidly, which helps maintain their numbers. They are known carriers of diseases and can cause significant damage to structures and food supplies, making them a key pest of concern in pest control.

While other species like the Roof Rat and the Black Rat are also present in the U.S., they are not as widespread as the Norway Rat. The House Mouse, while common in homes, is not classified as a rat. Understanding this makes it clear why the Norway Rat holds the title of the most common rat in America.
