Voles and mice may appear strikingly similar at first, especially if you are trying to determine which pest is occupying your home or backyard. However, there are key differences that you can identify in order to help you tell the difference between a vole vs mouse. For example, the families for both of these creatures are different: voles are members of the Cricetidae family, while mice are members of the murids family. But this isn’t where their differences end.

In this article, we will endeavor to describe the differences between voles and mice, including helpful tips that can assist you in telling these pesky rodents apart. Whether you are worried you have mice in your home or simply want to learn how to identify a vole upon first glance, we’ve got you covered. Let’s compare vole vs mouse now.

The Main Differences Between Vole vs Mouse

There are key differences between vole vs mouse. Mice have a leaner body when compared to voles, while voles are stockier in appearance. Voles also have smaller ears and a shorter tail than mice, as a mouse’s tail is usually as long as their body. The habitat preferences between voles vs mice can also be considered a key difference between these two species; voles prefer open outdoor areas which is why you will often find them outside, while mice prefer enclosed and indoor spaces. 

But this isn’t where these differences end. Let’s dive in and discuss the key similarities and differences between these two commonly confused rodents.

Vole vs Mouse: Face and Body Appearance

One of the key differences in a vole vs mouse situation is their overall appearance, including their face and body shape. Voles have a thicker and stockier body when compared to mice, a notoriously skinny and lean rodent. Mice also have larger ears and eyes when compared to voles- the ears and eyes of a vole are significantly smaller in appearance, though it may take some time to tell these two rodents apart.

Both rodents have brown or black fur, but the overall body shape should give you some insight into which rodent is which. A mouse’s body is designed to be narrow and skinny, adept at shimmying through tight areas and locations, while voles prefer to be in open areas. Therefore, their bodies are not as thin.

Vole vs Mouse: Habitat

Another key difference between voles and mice is their preferred habitat. Voles are regularly found outside the home, in gardens, lawns, and backyard landscaping, while mice are more often found inside homes. This is because mice are accustomed to enclosed spaces and prefer their bodies to be touching walls and objects in order to feel safe.

Mice also tend to be more opportunistic foragers than voles are, which may bring mice inside of your home while a shyer vole is more likely to stay outside. Mice are more likely to seek shelter indoors for their nests, while voles are comfortable digging underground burrows or outdoor nests.

Vole vs Mouse: Diet

The difference in a vole vs mouse diet is another example of the differences between these two rodents. The two animals are similar in size and overall diet preferences. However, there are some key differences between the average vole and the average mouse. For example, mice are considered more omnivorous than voles, eating more insects and even food taken from human pantries. Voles are far more content with plant matter to eat.

However, this isn’t to say that a vole won’t take advantage of a bug or a human snack from time to time. Given their shy nature, voles are less likely to seek out food beyond the comforts of the great outdoors, while mice are extremely opportunistic. This is why it is important to check your pantry if you think a mouse has invaded your home!

Vole vs Mouse: Tail Length

Another key difference between a vole vs mouse is the length of their tail. Taking a glance at a mouse when it is beside a vole will show these differences clearly, as mice have much longer tails than voles do. While a vole still has a significant tail, mice have a tail that is at least as long as their bodies, if not longer.

Vole tails average around half of their body in length, which makes their tail much shorter than mice. When combined with a vole’s smaller ears and eyes, it should be a bit more obvious which type of rodent you are dealing with!

Vole vs Mouse: Reproductive Habits

Another difference between voles and mice is their reproductive habits. While voles and mice both have similar lifespans of roughly a year in the wild, their reproductive habits differ somewhat. Voles breed throughout the year, though spring is their preferred time of year, while mice breed anytime of the year without preference.

Mice also have a shorter gestation period when compared to voles, averaging 10-20 days when compared to a vole’s 20-30 day period. Both rodents have litters of at least 3-7 babies, but mice typically birth more young than voles do. Mice average anywhere from 5-15 babies, while voles have an average of 3-10 babies.
