Do Mice Hibernate?

November 27, 2023

Maine winters are not for the faint of heart. It requires proper gear and grit to get through the season. While hibernation is a solid option for bears, it’s not for us or every animal. As for mice, you’re probably thinking there’s no way these small rodents could endure winter without tucking themselves away and you're partly right. In this article, we’ll answer the question, “do mice hibernate?” and discuss how mice spend their winters.

Identifying mice in Maine

Before we go on, we thought it worth mentioning that Maine is home to more than one species of mouse. In fact, in central and southern Maine, property owners often find themselves battling the common house mouse, the deer mouse, and the white-footed mouse. All three species are similar in appearance, have a high reproductive rate, and as for how they react to cold weather… well, keep reading friends. 

Do mice hibernate in Maine?

Whether indoors or outside, mice do not hibernate. Unfortunately, cold weather does not deter mice from making a nuisance of themselves or from damaging property. In fact, not much stops mice from infesting homes and businesses in Maine and certainly not snow on the ground. 

Where mice go in the winter in Maine  

When temperatures drop and the ability to find food outside becomes harder, mice (and rats) often enter structures for warmth and sustenance. They usually slip into homes and buildings through small openings or cracks and establish nests in walls, attics, basements, or pantries.

How mice behave inside in the winter

Indoors, mice are less influenced by the external weather conditions and will remain active year-round. As is the case in any season, once mice sneak indoors, they will forage for food in the kitchen, steal bird seed from the garage, chew on just about anything they can find (including electrical wires), damage property, and leave urine stains and droppings everywhere they go. 

Damages caused by a mouse infestation

When mice spend their winters indoors, they will cause damage. They’ll use those ever-growing incisors to chew on anything they find -from support beams to electrical wires to furniture to cardboard boxes- and the resulting damage ranges from minor cosmetic issues to more extensive damage. Why they may even create fire hazards. Not only that, but they may also contaminate attic insulation and surfaces with their droppings and damage furniture and personal belongings.

They also introduce health risks

In addition to the damages noted above, when mice stick around for the winter (or any other season) they may bring with them disease, cause food contamination, and rob homeowners of their peace of mind.
