Rats and Mice During a Cold Snap: Why They Enter Your Home and How to Stop Them

When a cold snap hits, homeowners often notice an increase in unwanted visitors—rats and mice. As temperatures drop, rodents actively seek warmth, food, and shelter, and your home can become the perfect target. Understanding why rats and mice enter homes during cold weather and how to prevent an infestation is key to protecting your property and your health.

Why Rats and Mice Enter Homes During Cold Weather

Rats and mice are survival experts. When outdoor temperatures fall, their natural food sources become scarce and staying warm becomes difficult. Homes offer everything they need:

• Warmth: Heated buildings provide ideal nesting conditions.

• Food: Pantries, pet food, and trash are easy food sources.

• Shelter: Walls, attics, basements, and crawl spaces offer safe hiding spots.

Even small openings—cracks in foundations, gaps around doors, or vents—can allow rodents to squeeze inside. Mice can fit through holes as small as a dime, while rats need only a quarter-sized opening.

Signs of Rats or Mice in Your Home

During a cold snap, rodent activity often increases. Common warning signs include:

• Scratching or scurrying noises in walls or ceilings

• Droppings in kitchens, pantries, or basements

• Chewed wires, insulation, or food packaging

• Nests made from shredded paper or fabric

• Strong musky odors

If you notice these signs, it’s important to act quickly. Rodents reproduce rapidly, and a small problem can turn into a serious infestation in a short time.

Health Risks of Rodents in the Home

Rats and mice are more than just a nuisance. They can pose serious health and safety risks, including:

• Disease transmission: Rodents can carry hantavirus, salmonella, and leptospirosis.

• Allergies and asthma: Rodent droppings and dander can worsen respiratory conditions.

• Fire hazards: Chewed electrical wiring increases the risk of house fires.

Keeping rodents out during winter is essential for maintaining a safe and healthy home.

How to Prevent Rats and Mice From Entering Your Home

Cold weather rodent prevention starts with making your home less attractive and less accessible.

1. Seal Entry Points

Inspect your home for cracks, gaps, and holes. Seal them with caulk, steel wool, or metal mesh, especially around:

• Doors and windows

• Utility lines and pipes

• Vents and chimneys

2. Eliminate Food Sources

• Store food in airtight containers

• Clean up crumbs and spills promptly

• Secure trash cans with tight-fitting lids

• Avoid leaving pet food out overnight

3. Reduce Outdoor Attractions

• Keep firewood stacked away from the house

• Trim vegetation away from foundations

• Remove clutter near exterior walls

4. Maintain Warm, Dry Spaces

Fix leaks and reduce moisture in basements and crawl spaces. Rodents are drawn to damp, sheltered areas during winter.
