Cold Weather Forces Rodents Indoors
As temperatures drop in December, rodents search for the warmest and safest shelter they can find. Homes provide steady heat, easy hiding spots, and protection from freezing outdoor conditions. Basements, garages, and crawlspaces often become entry points, and once mice find warmth, they rarely leave on their own.
Holiday Cooking Increases Attractants
December brings heavy cooking, baking, and meal prep. Extra groceries in the pantry, food left out during gatherings, and added trash volume all create strong scent trails that attract rodents. Even sealed packages can draw mice if they are stored low or pressed against walls.
Longer Nights Lead to More Activity
Rodents are most active when the home is quiet. December’s long nights effectively extend the hours when mice feel safe to move around. Homeowners often notice scratching in the walls after dark or find evidence in the kitchen the next morning.
Small Gaps Open Up as Temperatures Drop
Cold weather can cause minor shifts in siding, foundations, and utility entry points. Gaps that were sealed in summer may widen enough for a mouse to squeeze through. Rodents need only a dime-sized opening to access a home, making December a peak time for new infestations.
Practical Steps to Reduce Winter Rodent Issues
Keeping food in airtight containers, cleaning up crumbs quickly, sealing visible gaps, and ensuring trash is secured can make a big difference. Simple maintenance steps often stop rodents before they establish nests.
When Professional Help Is Needed
If scratching sounds, droppings, or shredded insulation appear, the issue is usually larger than it seems. A professional winter inspection identifies active entry points and stops the problem from spreading into additional rooms or floors.
