Mice in Winter: Ever Wonder Where They Hide When It Gets Cold?

When the temperature drops and we all start reaching for electric blankets and steaming mugs of hot chocolate, we’re not the only ones desperately trying to get warm. It’s no coincidence that we see higher numbers of mice in winter. Colder weather leaves them searching for better shelter, increased warmth, and reliable food sources – and understanding how they behave in the winter months will help you prevent infestations.

How do mice live in the winter?

If you’re wondering, “Where do mice live in winter?”, their main goal is to find somewhere warm and safe before the cold weather really sets in. Mice are incredibly resourceful. Outdoors, they gather materials like grass, leaves, and shredded fabric to build insulated nests. Indoors, they’ll do pretty much the same, but with access to additional materials like loft insulation and cardboard. Mice in winter have fewer outdoor food sources, which means they’re far more likely to venture towards your home when the temperature drops.

Why Mice Become More Active in Winter

As temperatures plummet, mouse activity increases. They’re frantically looking for food sources, warmth, and protection from the bitter weather, so they take greater risks and come closer to homes.

Food and shelter drive winter activity

Natural food sources are in short supply over winter, so kitchens, bins, and pet food bowls become more tempting than ever. If someone asks, where do mice live in winter, the answer is: often in people’s homes.

Breeding and survival instincts

Mice don’t stop breeding in winter. If they get into your home, they may even breed more, thanks to the warmth and security your property provides. Their strong survival instincts lead them to seek protected nesting sites, which is why they’re so attracted to homes. This means you’ll often have more sightings of mice in winter, and often have more infestations at this time of year.

Where Do Mice Live in Winter?

Mice will move in wherever they can survive comfortably. They may be very close to your home – or even inside it – without you even realising…

Inside your home

Mice are great at squeezing into tight spaces and staying well hidden. Indoors, their favourite winter hiding spots include:

• Lofts and attics
• Behind kitchen appliances
• Inside wall cavities
• Under floorboards
• Behind stored items in garages.

Outdoor Shelters

If they don’t move into your home, mice may still shelter close by. Many set up camp just outside your home, in areas including:

• Compost heaps
• Sheds and garages
• Wood piles
• Under decking
• Overgrown areas in your garden.

From these outdoor bases, they’ll plan nightly food-finding outings, where your home is often a great source of supplies.

How to Keep Mice Out of the House in Winter

A combination of prevention, home maintenance, and ongoing monitoring can keep your property mouse-free. To prevent mice from entering your home in winter, seal gaps, remove food sources, and keep both indoor and outdoor spaces tidy to make your home less inviting.

Securing your home

A mouse can squeeze through gaps you’d never think possible, so sealing entry points is vital. Check and fix:

• Gaps around doors and windows
• Broken vents
• Damaged walls and fascias
• Holes around pipework.

Ongoing monitoring and maintenance

Even if you’re sure that any entry points are completely sealed, it’s important to keep checking for things like droppings, gnaw marks, and shredded nesting materials, which may appear behind appliances, in loft spaces, in garages and sheds, and around garden borders. Humane traps or monitoring stations can help you spot early signs of activity – and if you do suspect an infestation, it’s best to call in the professionals sooner rather than later.

Keeping Your Home Safe from Winter Mice

Your home is attractive to mice in winter for three reasons: warmth, food, and survival. They may be quick and surprisingly clever, but by understanding their habits and learning to spot the signs, you can stay one step ahead. Mice can breed very quickly, but with regular prevention and monitoring, you can keep your property rodent-free.
