Deer & White-footed Mice
Two mice belonging to the genus Peromyscus are collectively called “field” mice in pest management. The deer mouse occurs in most of Canada and the United States (except the southeastern states). The white-footed mouse overlaps the deer mouse in the eastern and central U.S. and extends into the southeast. Both have large eyes and are sharply bicolored with white along the bottom of their bodies. While they may be difficult to tell apart from each other, they look different from house mice, which have smaller eyes and are more uniform in color.
