The roof rat has a dark, brownish upper body with gray underneath and is an average of 15” in length. They are known for their long, slender tails, which are longer than the head and body combined, and their large, nearly hairless ears. On average, they weigh up to 9 oz. and produce several litters of 2–8 babies annually. You'll commonly find them in upper floors of buildings, trees, lush vegetation, seaports, ships, in the South, and along coastlines.
