A supremely adaptable species, the Asian House Rat is to be found in many man-made habitats including agricultural and wholly urban areas. It is omnivorous, feeding on all manner of farmyard waste and food scraps. It is a fast runner, can climb well and can jump up to 50 cm.

The fur on the dorsal side is olive-brown, and the ventral side generally lighter. The tail is very dark grey and nearly naked. The ears are large and the eyes jet black. Juveniles have a relatively larger head and smaller body.

The species is closely related to the European House Rat Rattus rattus, but recent studies suggest it is a separate species. It probably occurs throughout Southeast Asia.
