Native to the Orient, Asia Minor, and Siberia, Old World rats were introduced to North America on the ships of the early voyagers. These highly adaptable rats continue to enter new regions on board ships, trains, and trucks carrying freight and other goods around the world.
In Washington, they are now found wherever humans have established permanent residence or industry. Old World rats include the Norway rat ( Rattus norvegicus, Fig. 1), also known as the brown rat, sewer rat, or wharf rat, and the black rat ( Rattus rattus), also called the roof rat.
