What is the scientific name for the sewer rat?

The scientific name for the sewer rat is Rattus norvegicus. This species is commonly associated with urban environments, often inhabiting sewers, basements, and other areas where food is available. It is known for its adaptability and is one of the most widespread rodent species in the world.

In contrast, Rattus rattus refers to the black rat, which is typically found in more tropical environments and is less associated with sewers than Rattus norvegicus. Mus musculus is the scientific nomenclature for the house mouse, another common rodent, but distinctly different from the sewer rat in terms of behavior and habitat. Peromyscus maniculatus, known as the deer mouse, is also unrelated to the sewer rat and can be found in a variety of habitats but is not typically associated with urban settings like Rattus norvegicus.

Understanding the distinctions among these species is important for effective pest control and public health management, especially in urban environments where sewer rats are prevalent.
