Just like human beings, squirrels like to stay indoors and keep warm during the cold winter months. Squirrels make early preparation for the cold season by collecting and burying nuts and seeds in small shallow holes which they cover with dirt to retrieve later. This hoarding of food is known as caching. The squirrels don’t remember all the caching locations and in this way help the ecology of the area by planting shrubs, trees and other plants.
The squirrels also begin to feed aggressively as winter approaches to store body fat. The critter may eat up to its own body weight in food in a week in preparation for the cold months ahead. They bulk up significantly and this process helps with sustenance and to keep them warm. Where the squirrels go exactly depends on the species.
Do Squirrels Hibernate?
There is a lot of debate on whether or not squirrels hibernate but most experts agree only some species of squirrels hibernate.
Ground squirrels dig burrows in the ground where they bunker-in for the season. They prefer to burrow on the sloped ground to prevent their enclave from flooding and under rocks or logs to protect them from predators. Ground squirrels hibernate for the winter. They may wake up a few times during this period to forage especially if they have stashed away plenty of food.
Some species such as the Richardson’s ground squirrel (native to Manitoba, Saskatchewan and Southern Alberta) can hibernate for up to nine months.
Flying squirrels and tree squirrels do not hibernate. They maintain roughly the same body temperature throughout the year. These species make dens in tree trunks to hide from the cold weather. These also build dreys which are sturdy nests made from tree branches and twigs, similar to the typical bird nest. The squirrel will use the extra material for the dray during winter and can nest up to 30 feet high in the tree.
Squirrels stay in their nests for most of the day during winter and sleep for 18-20 hours. They may venture outside during warmer days or mild winters but otherwise prefer to stay inside. They huddle in tight groups to keep each other warm. This is why you rarely see squirrels in winter causing many people to assume that all squirrels hibernate.
Winter Damage Caused by Squirrels
Squirrels help a great deal with dispersing seeds for hardwood trees but they can be destructive for property owners. The squirrels will dig up the yard, tear up manicured lawns and uproot potted plants while hiding their food stash.
The dirt mounds are a tripping hazard and can also damage farm and yard equipment. The burrowing can also kill trees, especially during the warmer seasons. Finally, the rodents will happily nest in your garage, shed or attic given the opportunity. A squirrel can squeeze through a hole a 1 ½ inch hole so the likelihood there are gaps and cracks that the squirrels can fit through and into your house is extremely high.
