If you’ve heard scratching or squeaking coming from your walls at night, you’re not alone. Many Raleigh-area homeowners deal with this problem, especially as temperatures drop or food becomes scarce outdoors.
Unfortunately, when mice move into your walls, they don’t stay hidden for long. They chew wiring, damage insulation, and leave droppings that can spread bacteria—all while reproducing quickly.
If you’re wondering how to get rid of mice in walls, here’s what you need to know about identifying, removing, and preventing these pests from returning.

How Mice Get Inside Homes
Mice can squeeze through gaps as small as a dime, so even a well-sealed home can be vulnerable. They look for warmth, shelter, and easy access to food—making wall voids a perfect hiding place.
Common entry points include:
– Crawl space vents or damaged screens
– Cracks in the foundation or siding
– Gaps around utility lines and plumbing
– Air ducts, roof vents, and attic openings
– Poorly sealed door frames and window sills

Once inside, mice often nest in quiet, enclosed areas such as attics, basements, and interior walls. A single female can produce several litters each year, which means a small issue can become a full mice infestation quickly.
Signs You Have Mice in Your Walls
Because mice tend to stay out of sight, it’s often the signs of activity that give them away.

– Scratching or scurrying noises at night behind walls or ceilings
– Mouse droppings along baseboards, inside cabinets, or near food storage
– Gnaw marks on boxes, wiring, or baseboards
– Pets suddenly focused on a specific wall or area
– A stale or musty smell that lingers even after cleaning
If you notice two or more of these signs, it’s likely you have a mouse problem that needs attention.
How to Get Rid of Mice in Walls
Once mice make it inside, quick action is key. Follow these steps to eliminate the infestation and keep it from returning.
-
1. Seal Entry Points
Start by identifying and closing off where mice are entering. Use steel wool or wire mesh to plug holes around pipes, vents, and electrical cables. Avoid materials like foam or rubber—mice can easily chew through them.
If your home has a crawl space, check vents and foundation cracks for gaps and seal them with caulk or concrete.
-
2. Set Multiple Traps
Snap traps and live traps are among the most effective tools for removing mice. Place traps along walls, behind appliances, and near droppings or gnaw marks; these are high-traffic routes.
Use a small dab of peanut butter or nut spread for bait. If nothing is caught within two days, reposition traps to a new location. Setting multiple traps increases your chances of catching mice quickly.
-
3. Use Enclosed Bait Stations
For larger infestations, bait stations can help reduce the population safely. These tamper-resistant containers keep bait out of reach from children and pets while targeting the rodents inside your walls.
Avoid using loose rodenticide pellets indoors, always stick to enclosed stations or contact a pest control specialist for professional placement and monitoring.

4. Try Natural Deterrents (For Mild Activity)
Natural deterrents can help for light activity or prevention:
- Peppermint oil: Soak cotton balls and place them where you suspect mice are entering.
- Crushed red pepper flakes: Sprinkle near baseboards or known gaps.
These may discourage mice from returning, but they won’t stop an active infestation. Physical removal and sealing remain the most reliable methods.
What to Do About Dead Mice in Walls
If you notice a strong odor coming from your walls, there may be a dead mouse trapped inside. The smell can linger for weeks if not addressed. Because removing a dead mouse often requires cutting into drywall and dealing with wiring, it’s safest to call a pest control company for proper removal and sanitization.
Our team uses specialized tools to locate the source and remove contamination without unnecessary wall damage.
Cleaning After a Mouse Infestation
Once the mice are gone, proper cleanup is crucial.
– Wear gloves and a mask before handling contaminated materials.
– Spray droppings or nesting areas with disinfectant—never sweep or vacuum them dry.
– Wipe down floors, counters, and baseboards thoroughly.
– Dispose of contaminated items in sealed plastic bags.
If you’re unsure whether cleanup is safe, Stomp can handle sanitation as part of your service.
How to Keep Mice From Coming Back
Preventing future infestations is just as important as eliminating the current one.
– Seal cracks in foundations, siding, and around doors and windows
– Store food and pet food in airtight containers
– Wipe crumbs and spills immediately
– Replace torn window screens and worn door sweeps
– Keep woodpiles and debris at least 20 feet away from your house
– Trim trees and shrubs so they don’t touch your roof or siding

A sealed, clean home gives mice fewer hiding places and discourages nesting.

FAQs About Getting Rid of Mice in Walls
-
How long can mice live in walls?
If they have food and water, mice can survive for months inside wall voids. That’s why sealing and removing food sources is key to breaking the cycle.
-
Do ultrasonic pest repellents work?
Results vary. These devices can help deter mice in small areas but should never replace traps or exclusion methods.
-
What’s the best bait for mouse traps?
High-protein foods like peanut butter or chocolate spread attract mice more effectively than cheese.
-
Can I use glue traps?
While glue traps catch mice, they’re not the most humane option and can make cleanup difficult. Snap traps or bait stations are safer and more efficient.
-
How do professionals get rid of mice in walls?
Pest control companies like Stomp combine inspection, targeted trapping, and exclusion to eliminate mice and stop them from returning.
