Field Mouse in Winter

Field mice have developed various strategies to survive the harsh winter months. Unlike some animals, they do not hibernate. Instead, they remain active throughout the winter, relying on their stored food supplies and burrows to endure the cold. Field mice typically begin preparing for winter in the late summer and early fall, gathering seeds, grains, and other food sources to store in their underground nests. These food reserves are crucial, as foraging becomes difficult when snow covers the ground.

During winter, field mice seek shelter in their burrows, which are usually dug deep enough to protect them from freezing temperatures. The burrows are insulated with grass, leaves, and other plant materials to help retain warmth. In colder regions, field mice may also move closer to human structures, such as barns, sheds, or even homes, where they can find additional warmth and food. Their survival largely depends on how well they prepared during the warmer months, and they are known to be resourceful and adaptable in finding sustenance even when conditions are challenging.

Field mice are also communal during winter, often sharing burrows with other mice to conserve body heat. This cooperation helps them withstand the cold, but it can also lead to population growth if they are not controlled. If you want to prevent field mice from entering your home or property during the winter, it’s essential to seal any potential entry points and remove food sources that might attract them.
