Dealing with mice inside your walls can be tricky, but it’s a common problem. If you hear scratching, gnawing, or movement in the walls—especially at night—you may have a mouse infestation hidden behind the plaster or drywall.

So, how to get rid of mice in walls? First, identify entry points. Mice often enter through holes around utility pipes, vents, or damaged wall coverings. Seal any visible gaps using materials like steel wool, metal mesh, and expanding foam.

Next, set traps near suspected wall entry points, such as under cabinets, behind appliances, or along baseboards. Use snap traps or bait stations with peanut butter or chocolate for effective results. Avoid placing traps too far into wall cavities unless you’re using professional-grade equipment.

If the infestation is deeper in the walls, consider using ultrasonic repellents. These devices emit high-frequency sounds that disturb mice but are inaudible to humans and pets.

Sometimes, you may need to cut into a wall to remove a dead mouse or nest, especially if you detect foul odors. In such cases, it’s best to call a licensed pest control expert to handle the removal safely and minimize property damage.

Finally, maintain good sanitation and check for signs of reinfestation regularly. With a proactive approach, you can get rid of mice in walls and keep them from coming back.
