Most people assume pests go dormant in winter. But for rats, the colder months are prime time to invade homes. As temperatures drop across Surrey, Langley, and the rest of the Lower Mainland, rats seek warmth, food, and shelter—and your home becomes a target.
Here’s why rat activity spikes in winter and what you can do to keep them out.
Why Rats Invade Homes in Winter
Rats are opportunistic. When outdoor temperatures drop, their natural food sources diminish, and their outdoor burrows become less viable. Your home offers everything they need:
Warmth from attics, walls, and crawlspaces
Food from pantries, pet dishes, and improperly stored garbage
Shelter from predators and harsh weather
Once inside, rats establish nests quickly. With their rapid reproduction cycle, a small winter invasion can turn into a full‑blown infestation by spring.
The Hidden Risks of a Winter Rat Infestation
Beyond the unsettling signs of scratching and droppings, rats pose serious threats:
Fire hazard: Rats gnaw on electrical wiring, exposing live wires and increasing fire risk
Health risks: Rat urine and droppings can spread hantavirus, salmonella, and other pathogens
Structural damage: Rats chew through insulation, drywall, wood, and even PVC pipes
Contaminated insulation: Urine and feces degrade insulation efficiency, raising heating costs
How to Rat‑Proof Your Home Before Winter Hits
Prevention is the most effective defense. Here are key steps to protect your home:
Seal entry points: Rats can squeeze through holes as small as a quarter. Inspect your foundation, roofline, and around pipes for gaps.
Trim trees and shrubs: Overhanging branches provide rats with easy access to your roof and attic.
Secure garbage bins: Use tight‑fitting lids and store bins away from your home’s exterior walls.
Eliminate food sources: Keep pet food indoors, clean up spills promptly, and store pantry items in sealed containers.
Schedule a professional inspection: A licensed exterminator can identify vulnerable areas you might miss.
