Why Rodents Move Indoors in December
Pittsburgh’s cold December weather drives rodents like mice and rats indoors in search of warmth, food, and shelter. Older homes, rowhouses, and properties with basements are particularly vulnerable. Rodents are not just a nuisance—they can cause property damage, contaminate food, and carry diseases.
Common Entry Points
- Cracks in foundations or walls
- Gaps around doors and windows
- Dryer vents, chimneys, and crawlspaces
- Garage doors and pet entrances
Signs of Rodent Activity
- Scratching or scurrying sounds at night
- Droppings along baseboards or in pantries
- Chewed wiring, insulation, or furniture
- Grease marks near walls or entry points
Preventing Rodent Infestations in December
- Seal Cracks & Gaps: Inspect the foundation, walls, and windows for small openings.
- Proper Food Storage: Keep pet food, dry goods, and holiday treats sealed.
- Declutter Storage Areas: Remove cardboard, paper, and unused boxes that rodents can nest in.
- Set Traps Strategically: Place traps near walls, behind appliances, and in attics.
- Maintain Outdoor Areas: Trim vegetation and store firewood away from the house.
