Some people may find it difficult to distinguish the differences between rats and mice. Rats and mice have many similar characteristics, however, there are several distinct differences – not only in their appearance, but also in their food preferences and preferred habitat. There are three species of rodents that will commonly infest structures: Norway rats, roof rats (black rats) and the house mouse.
