When temperatures begin to drop in Central Virginia, many homeowners focus on staying warm and preparing for the holidays. Unfortunately, they’re not the only ones looking for shelter. Cold weather signals the start of rodent season, as mice and rats actively seek warmth, food, and nesting sites inside homes. To schedule an inspection visit PestNowCVA.com.
Winter is one of the most common times for rodent infestations to begin, and by the time homeowners notice signs of activity, rodents have often already settled in. Understanding why rodents invade during cold weather—and knowing what to watch for—can help prevent costly damage and ongoing problems.
Why Cold Weather Drives Rodents Indoors
Rodents are survival experts. As outdoor temperatures fall, food sources become scarce and exposure to the elements becomes dangerous. Homes provide the perfect solution, offering:
- Consistent warmth from heating systems
- Easy access to food and water
- Protection from predators and harsh weather
- Safe nesting materials like insulation, cardboard, and fabric
Even newer homes aren’t immune. Mice can squeeze through openings as small as a dime, and rats only need a gap about the size of a quarter. Small cracks, vents, utility line openings, and crawl space doors are all common entry points.
Common Rodents Active in Central Virginia During Winter
The two most common winter rodent invaders in Central VA are:
House Mice
Small, fast, and quiet, mice often go unnoticed at first. They nest in walls, attics, crawl spaces, and behind appliances, reproducing rapidly once inside.
Rats
Larger and more destructive, rats often target crawl spaces, garages, and basements. They cause significant damage to insulation, ductwork, and wiring.
Once rodents move in, they don’t hibernate—they stay active all winter long.
Signs Rodents Have Already Moved In
Rodents are excellent at staying hidden, but they leave behind clues. Common warning signs include:
- Scratching or scurrying sounds in walls or ceilings, especially at night
- Droppings in kitchens, pantries, garages, or crawl spaces
- Gnaw marks on wiring, wood, or food packaging
- Shredded insulation or paper used for nesting
- Musty or ammonia-like odors
Ignoring these early signs allows infestations to grow quickly. A single pair of mice can multiply into dozens within months.
Why Rodents Are a Serious Winter Problem
Rodents aren’t just a nuisance—they pose real risks to your home and family. During winter, infestations often worsen because rodents remain undisturbed for long periods.
Potential issues include:
- Fire hazards from chewed electrical wiring
- Structural damage to insulation, ducts, and wood framing
- Health concerns, including Salmonella, Hantavirus, and allergens
- Contamination of food storage areas
Because rodents stay hidden during winter, damage often continues unnoticed until spring inspections or major repairs are needed.
Where Rodents Commonly Nest in Winter
In Central Virginia homes, rodents most often target:
- Crawl spaces with poor sealing or moisture issues
- Attics with exposed insulation
- Basements and utility rooms
- Garages with gaps or clutter
- Wall voids near heating systems
These areas offer warmth, darkness, and minimal disturbance—ideal conditions for nesting.
How to Reduce Rodent Activity During Cold Weather
Homeowners can take preventive steps to reduce rodent risk:
- Seal exterior gaps, vents, and foundation openings
- Install door sweeps and repair weatherstripping
- Store food in airtight containers
- Keep storage areas organized and clutter-free
- Move firewood and debris away from the home
- Address moisture problems in crawl spaces and basements
While these measures help, they may not stop rodents that are already inside or prevent determined invaders.
