When cold weather hits Seymour, WI, winter mice start looking for warm, cozy spots to shelter — and your home could be the perfect hideout. These tiny critters are experts at sneaking inside unnoticed and setting up shop in walls, basements, attics, or crawl spaces.

At Werner Pest & Odor Control, we know how to spot the signs of a winter mice problem before it gets out of hand. Wondering if you have some unwelcome guests this season? Here’s what to look for.

1. Droppings: Clear Evidence of Mice

One of the most obvious signs of winter mice is their droppings. These small, black pellets show up in places like cupboards, pantry shelves, behind appliances, or along walls. Finding droppings means mice are definitely around and active in your home.

Always be cautious when cleaning droppings—wear gloves and disinfect surfaces to avoid health risks.

2. Scratching and Scurrying Sounds at Night

Winter mice are usually more active at night, so if you hear scratching, scampering, or squeaking noises inside walls or ceilings, you might have visitors. These sounds can come from attics, basements, or inside walls—especially when the weather outside is freezing cold.

3. Gnaw Marks Are a Tell-Tale Sign

Since winter mice constantly gnaw to keep their teeth sharp, look for teeth marks on food packaging, wooden baseboards, wiring, or insulation. Torn bags or chewed-up boxes in the pantry are a red flag.

4. Nesting Materials in Hidden Corners

Mice build nests from shredded paper, fabric scraps, insulation, and other soft materials. If you find piles of this kind of debris behind appliances, inside closets, or under furniture, winter mice could be settling in.

5. Musty Odors Indicate Mice Activity

A strong, lingering musty smell inside your home can signal the presence of winter mice. This odor often comes from urine and nesting areas and is usually most noticeable in enclosed spots like cabinets, crawl spaces, or basements.

Why Winter Means More Mice Indoors

The cold months force mice to find warm places to survive, which often means your home. Winter mice can squeeze through tiny openings—about the size of a dime—and once inside, they breed quickly. A few mice can quickly turn into a full-blown infestation if not caught early.
