A scratching sound you can’t ignore. It usually starts late at night, a faint scratching or scurrying behind the drywall. At first, you might brush it off as your imagination, but as days go by, the sound grows more frequent. Homeowners and property managers across Minnesota know that this unsettling noise often means one thing: mice have found a way inside your home and into your walls. These tiny invaders don’t just create noise, they cause real damage and health risks if left unchecked. They also have 5 or more litters in one year.
Recognizing the Signs of Mice in Your Walls
Before taking action, it’s important to confirm that the problem is indeed mice. Common signs include:
Persistent scratching or chewing sounds, especially at night.
Tiny droppings near baseboards, in cupboards, or along walls.
Gnaw marks on wood, wires, or insulation.
Unpleasant odors, caused by nesting materials or waste.
Pet agitation, as cats or dogs often sense movement behind walls.
If these signs sound familiar, chances are good you have an active mouse infestation inside your walls.
Why Mice Choose Your Walls
Mice seek warmth, food, and safety—your walls offer all three. During Minnesota’s colder months, these pests squeeze through small cracks or openings around the foundation, vents, or utility lines. Once inside, they create hidden nests in insulation and chew through electrical wires, drywall, and even plumbing lines. Over time, this can lead to costly repairs and potential fire hazards.
How to Handle Mice in the Walls
You might be tempted to set traps or use over-the-counter repellents, but mice are intelligent and reproduce quickly. A few traps rarely solve the problem. Instead, follow these key steps:
Locate entry points – Inspect your home’s foundation, vents, and exterior walls for gaps as small as a dime.
Seal all openings – Use steel wool, caulk, or metal flashing to close gaps. Avoid foam sealants—mice can chew through them.
Remove attractants – Store food in airtight containers, clean up crumbs, and eliminate clutter that offers nesting sites.
Call a professional – Experts have the tools to identify hidden nests, safely remove mice, and ensure they don’t return.
