House Mouse: The adult house mouse is small and slender and about 1-2 inches long, excluding tail. The house mouse has large ears, pointed nose and small eyes. The tail is as long as the head and body combined. A mouse will eat almost anything, but prefer cereal grains, seeds, or sweet material. They require very little water, obtaining most of their water needs from their food. Mice can consume large quantities of stored seed and grains from farmers and granaries.
Norway Rat: The Norway rat is one of the largest, is brown or grey and up to 10 inches long with a similar tail length. They have acute hearing, poor eyesight, and usually active at night.
Roof Rats: Roof rats are blackish, brown or grey and can tend to have pink or white underbellies. Easily confused with Norway rats, however Roof rat’s tails are actually longer than their own body making that an easy way to distinguish between the two.
