You might think winter slows everything down, but for mice, it’s the busiest time of the year. When temperatures drop, these small animals start searching for warm, safe places to live. Unfortunately, that often means your restaurant or business becomes their winter getaway.

So, how does cold weather drive mice into restaurants and businesses? It’s simple, they’re looking for warmth, food, and shelter. Their outdoor homes freeze over, food becomes scarce, and buildings like yours offer everything they need to survive. At Skedaddle Humane Wildlife Control in Toronto, we see this pattern every year.

Mice in restaurants in winter is a real issue. You can’t control the temperature outside, but you can understand what attracts mice inside. Once you know what to watch for, you can prevent mice in businesses and stop winter mouse infestations before they start.

1. Seeking Warmth and Shelter

When the weather turns cold, you reach for a coat or head indoors. Mice do the same, except they don’t leave once they find a warm spot.

They squeeze through tiny openings in walls or foundations and settle into quiet areas where they won’t be disturbed. Inside, they can stay warm and hidden while still close to food and water sources.

Common indoor nesting spots include:

• Behind kitchen appliances and fridges
• Inside wall voids and ceilings
• Beneath storage racks or shelves
• In cardboard boxes or insulation

You might never see them, but signs like droppings, gnawed packaging, or faint scratching sounds at night can reveal their presence.

2. Easy Access to Food

Restaurants and commercial kitchens are heaven for mice in winter. With steady access to grains, produce, and leftovers, these small invaders can survive and thrive indoors.

Even a few crumbs under an oven or a torn bag of flour can attract them. Once inside, they’ll keep returning to the same food source night after night.

When we inspect businesses, we often find food spills, uncovered bins, or cluttered storage areas that act like a buffet for rodents. That’s why keeping food sealed and surfaces clean is essential to prevent mice in businesses and protect your reputation.

3. Cracks and Gaps Grow During Cold Weather

You might not realize it, but cold temperatures can help mice get inside. As building materials like brick, concrete, and wood contract, new openings can appear. Mice only need a hole the size of a dime to squeeze through.

These gaps often form around:

• Door frames and loading docks
• Foundation edges
• Utility lines and vents
• Roof flashing and siding

Once inside, they don’t leave on their own. Our technicians often install one-way doors that let animals exit safely while preventing them from re-entering. It’s a humane and effective solution that keeps your business secure through winter.

4. Constant Breeding Cycle

You might think mice stop breeding in cold weather, but that’s another misconception. Mice reproduce all year long, and their population often peaks right before winter.

A single female can have up to 10 litters per year, each with 6 to 10 pups. When outdoor food becomes scarce, these growing families move indoors, multiplying your problems fast.

Once they establish a nest inside your business, it doesn’t take long before the signs spread: gnawed wires, torn packaging, and unpleasant odours. This is why winter mouse infestations often happen quickly and quietly.

5. Protection From Predators

Outside, mice face predators like hawks, owls, and foxes. Inside your business, those threats disappear. A warm, quiet building offers total safety — especially when humans aren’t around at night.

Restaurants that close in the evening or warehouses that sit empty on weekends are ideal hiding spots. Mice can move freely through the space, nesting and feeding without detection.

That’s why we always remind business owners: prevention isn’t just about cleanliness, it’s about sealing entry points and staying proactive through the coldest months.

6. Deliveries and Supplies

You might unknowingly bring mice inside with your shipments. Boxes, food containers, and pallets from warehouses or trucks can hide rodents or nesting materials. Once inside your storage or kitchen area, they spread quickly.

We often recommend that businesses check deliveries before bringing them indoors. Even if you can’t do that every time, recognizing this risk helps explain how infestations start and how fast they can grow.

7. Nighttime Activity Goes Unnoticed

Mice are nocturnal, which means most of their activity happens when you’re not around. By the time you notice the signs during the day, they’ve already been active for hours overnight.

At night, they move freely across counters, pantries, and floors, looking for food. They leave behind droppings, gnaw marks, and sometimes a musty smell.

When employees arrive in the morning, it may look like nothing’s wrong, but small clues often tell a bigger story. That’s why professional inspections are essential to catch mice in restaurants in winter before they cause serious contamination or damage.
