Seeing Mice This Winter? You’re Not Alone.

Winter is the most active season for mice in Connecticut—and every year, homeowners and businesses are caught off guard by just how quickly a small problem turns into a major one.

As temperatures drop, mice aggressively seek warmth, shelter, and food, making homes, commercial buildings, and even vehicles prime targets. At Verdant Pest Control, winter consistently brings a surge in mouse activity calls—and this season has been no exception.

If you’re hearing scratching, finding droppings, or noticing unusual smells, chances are mice have already made themselves comfortable.

Why Winter Mouse Problems Escalate So Fast

Mice can squeeze through openings as small as a dime. During winter, they exploit:

  • Gaps created by temperature-related expansion and contraction

  • Utility line penetrations

  • Garage doors and door sweeps

  • Foundation and siding openings

  • Attic and roofline access points

Once inside, mice reproduce rapidly and often go unnoticed until damage or contamination becomes obvious.

The Risks of Ignoring a Winter Mouse Problem

A mouse infestation is more than a nuisance. Left untreated, mice can cause:

  • Contamination from droppings and urine

  • Damage to insulation, drywall, and stored items

  • Chewed electrical wiring (a serious fire risk)

  • Persistent odors in attics and wall voids

  • Increased activity as populations grow indoors

Winter infestations rarely “go away on their own”—they almost always worsen.

Mice in Cars: A Growing Winter Issue

One of the biggest increases we see in winter is mice entering vehicles.

Cars provide warmth, nesting material, and protection from predators—especially when parked overnight or left unused. Mice frequently nest:

  • Under the hood

  • In cabin air filters

  • Inside engine bays

  • Around wiring harnesses and insulation

This can lead to:

  • Chewed wiring

  • Warning lights and electrical failures

  • Costly, unexpected repairs

Verdant Pest Control can help address vehicle-related rodent activity and reduce the chances of repeat issues.

Our Winter Mouse Control Approach

1) Thorough Inspection

We identify:

  • Active areas

  • Entry points

  • Nesting locations

  • Conditions attracting mice indoors

2) Targeted Control

Based on the inspection, we implement a plan that may include:

  • Strategic trapping

  • Secured baiting where appropriate

  • Monitoring activity to confirm results

3) Entry Point Identification & Prevention

Catching mice is only part of the solution. We help identify how they’re getting inside and provide guidance—or exclusion services—to prevent continued access.
