What distinguishing features separate white-footed and deer mice from house mice?

The distinguishing features that separate white-footed and deer mice from house mice primarily focus on their physical characteristics, particularly the presence of white feet and larger eyes. White-footed and deer mice are notable for their white underparts and feet, which contrast significantly with their overall brown or gray fur. In addition, these species often exhibit larger eyes relative to their body size, which is an adaptation for nocturnal activities.

House mice, on the other hand, typically have uniform fur color and do not showcase the same level of contrast in their coloration. These characteristics are crucial in identifying the mice during pest control assessments, as misidentifying these mice can affect the management strategies applied. The specific traits of white feet and larger eyes are clear identifiers, making them distinct from house mice.

Other options may touch upon valid aspects of mouse identification, but they do not specifically highlight the critical visual distinctions that are most useful in differentiating these particular mouse species.
