Squirrels are a familiar sight in gardens, even during the colder months. Unlike some other animals, squirrels do not hibernate in the UK. Instead, they have developed clever ways to survive winter, which sometimes causes them to seek shelter in homes. Squirrels have the ability to prepare and adapt. This adaptability ensures their survival but can sometimes bring them too close for comfort in urban settings.
How squirrels survive winter without hibernating
Squirrels don’t hibernate, but stay active throughout the year, relying on their physical adaptations and behaviours. Grey squirrels, the most common type in the UK, have thick fur to keep them warm. Their tails act both as balancing tools and as blankets when they curl up to sleep.
During autumn, squirrels collect and bury acorns, nuts and seeds. This process, known as caching, ensures they have a steady food supply during winter. Their remarkable memory helps them locate these stores, even if snow covers the ground. By hoarding food and using their keen sense of smell, they find nourishment even in the depths of winter. You’ll often spot squirrels digging to retrieve their hidden treasures.
Why squirrels enter lofts in winter
Though squirrels are well-equipped for the cold, they sometimes seek shelter indoors. Lofts provide a dry, warm environment, perfect for riding out storms or extremely cold spells. Unfortunately, this can lead to significant damage. Squirrels are excellent climbers and can enter through loose roof tiles, soffits or vents.
Once inside, they may chew wires, wood or insulation, creating hazards. Their activity can also disrupt your peace, especially early in the morning. So, squirrels don’t hibernate in your loft exactly. They will be coming and going throughout the winter. For anyone hearing suspicious noises in the loft or noticing squirrels causing damage, our professional pest control services can help prevent them from moving in.
Squirrels don’t hibernate but which animals do
Although squirrels don’t hibernate, some animals do. This is because they cannot find enough food or maintain their body heat. Hedgehogs, for instance, rely on insects, which are scarce during winter. Dormice hibernate because they need high-energy food, like seeds and fruits, which are also difficult to find in colder months.
UK rodents have many traits in common and not hibernating is one of them. Like squirrels, rats and mice also invade homes, lofts and garages, which makes them a common winter pest. Despite the challenges of winter, these rodents are all highly resourceful.
