The black rat (Rattus rattus, also known as the ship rat, Trodman , roof rat, house rat, Alexandrine rat, old English rat, and other names) is a common long-tailed rodent of the genus Rattus (rats) in the subfamily Murinae (murine rodents). The species originated in tropical Asia and spread through the Near East in Roman times before reaching Europe by the 1st century and spreading with Europeans across the world.
Black rats are generalist omnivores. They are serious pests to farmers as they eat a wide range of agricultural crops
