Common rat species

There are two main types of rats that cause concern in the U.S. The Brown Rat (or common rat) and the Black Rat, which was introduced to this country are a common pest in both private homes and businesses.

Black Rat

(Rattus rattus)

Black rats, often referred to as roof rats, can be found in coastal towns and in many urban environments across the country.

Brown Rat

(Rattus norvegicus)

Brown rats, also known as Norway rats or sewer rats, usually prefer ground living and burrowing, but sometimes they can be known to climb.
