Rodents in Winter: The Chilling Truth About Rats and Mice

Share

Winter in Southeast Alaska means cozying up indoors, but unfortunately, you might not be the only one looking for warmth. As temperatures drop, rodents like rats and mice are on the move—searching for food, shelter, and a place to nest. If you’re hearing strange noises in the walls or noticing suspicious droppings, it might be time to face the chilling truth: you could have unwanted guests. 

Let’s dive into why rodents are more active in winter, the damage they can cause, and how to protect your home or business. 

Why Are Rodents More Active in Winter?

Rodents, especially Norway rats, house mice, and deer mice, thrive in Southeast Alaska year-round. However, when the cold weather arrives, they start seeking warmth and food indoors. Homes, garages, and businesses become prime real estate for rodents to survive the winter.  Rodents are masters at sneaking inside, often entering through: 
  • Small cracks in walls, foundations, and vents 
  • Gaps in doors, windows, and utility lines 
  • Crawlspaces and attics with poor insulation
A mouse can fit through a hole the size of a dime, and rats can squeeze through a space as small as a quarter. If your home has weak spots, they will find a way in. 

The Damage Rodents Can Cause

Rodents are more than just an annoyance—they can wreak havoc on your home and health.

1. Property Damage

  • Gnawing: Rodents have sharp teeth that never stop growing. They’ll chew through wood, insulation, electrical wires, and even plumbing, creating costly repairs and potential fire hazards. 
  • Nesting: Rats and mice shred paper, fabric, and insulation to create cozy nests, leading to contaminated or damaged materials.

2. Health Risks

Rodents carry harmful diseases that can impact you and your family, such as: 

  • Hantavirus: Transmitted by deer mice through their droppings and urine. This virus can be deadly if inhaled in enclosed spaces. 
  • Salmonella: Spread when rodents contaminate food or kitchen surfaces. 
  • Leptospirosis: Bacteria found in rodent urine, which can cause flu-like symptoms and kidney damage. 

Even their droppings and dander can trigger allergies and respiratory issues, making rodent infestations a health risk you don’t want to ignore. 

Signs of Rodent Activity in Winter

How do you know if rats or mice have moved in? Look for these telltale signs: 

  • Droppings: Small, dark droppings in cabinets, pantries, or along walls. 
  • Noises: Scratching, scurrying, or squeaking sounds in walls, ceilings, or under floors, especially at night. 
  • Gnaw Marks: Chewed wires, furniture, or food packaging. 
  • Nests: Shredded paper, insulation, or fabric in quiet, hidden spaces like attics or basements. 
  • Odors: A strong, musky smell caused by rodent urine or nests.

If you spot any of these signs, don’t wait—rodents breed quickly. A small problem can turn into a full-blown infestation within weeks. 

How to Prevent Rodents This Winter

Here are a few practical tips to keep rodents from invading your home or business: 

  1. Seal Entry Points: Inspect your home for cracks, gaps, and holes. Use caulk, steel wool, or hardware cloth to seal them up. 
  2. Keep Food Sealed: Store food in airtight containers, and avoid leaving pet food out overnight. 
  3. Clean Regularly: Rodents are attracted to crumbs and clutter. Clean up spills, vacuum frequently, and declutter garages, basements, and storage spaces. 
  4. Secure Trash: Use rodent-proof trash cans with tight-fitting lids. Take garbage out regularly. 
  5. Eliminate Moisture: Fix leaky pipes and faucets, as rodents are drawn to water sources.
