Do you want to learn about the Different Types of Mice in Kentucky?
Finding information about the different types of mice in Kentucky was not as easy as I thought. Some information was incorrect, others were not enough, and some sites were just irrelevant.
That is why I created 7 Common Types of Mice in Kentucky.
While there are over 1000 species of mice in the world, this article will focus specifically on Kentucky or its surrounding areas, along with the role mice have in its ecological environment.
7 Types of Mice in Kentucky

This is another type of mouse that is present in Kentucky. It is called the deer mouse because it resembles the deer in terms of fur coloring. It is also one of the most abundant and common types of mice in the United States.
Deer mice feed primarily on seeds, grains, insects, and nuts among other food materials. They also eat small vertebrates, and they are nocturnal. In addition to that, these mice types usually build their nests under rocks, in burrows, and in some other sheltered areas.
These mice also have the ability to produce up to 8 litters in a year, each of these litters will have about 5 – 8 mouse pups.
Deer mice play an important ecosystem role. They eat plants and animals like insects and that helps in controlling their numbers. In addition to that, they are also food or preyed upon by other big animals like owls and snakes.
#3. White-Footed Mouse (Peromyscus leucopus)
Identifying Characteristics and Facts
- About 5 – 7 inches long.

This meadow jumping mouse is one of the most common types of mice that can be found in Kentucky. Identifying them is an easy thing since they stand in their unique characteristics. You will know them by their extremely long tails, long hind feet, yellowish-orange color along their sides, and darker brown band on their back.
The name ‘jumping mouse’ comes from the fact that they can jump high. This species of mouse has the ability to jump for up to a distance of 3 feet.
Another thing you can use to identify these types of rats is the bicolored tail. Looking into it, you will find that it has a combination of two colors including the white underside and the dark brown upper.
When it comes to feeding, these rats eat various types of foods including fruits, grasses, and seeds. They also eat insects and some species of spiders. Therefore, they help control their populations, and that is the important ecological role they play.
In addition to the ecological role of controlling or reducing insect populations, these rats or mice also help in the dispersal of seeds. They are under a great threat of habitat loss, and fragmentation.
#6. Eastern Harvest Mouse (Microtus ochrogaster)
Identifying Characteristics and Facts
- They weigh about 10 – 15 grams, are nocturnal, and can live for a period of up to 9.5 weeks.
