How To Get Rid of Mice in Walls

Hearing scratching or squeaking in your walls? You might have some uninvited guests. Mice and other rodents can be more than just a nuisance—they pose health risks and can cause significant damage to your home. At Fox Pest Control, we believe in empowering homeowners with the knowledge to tackle these issues head-on. Here’s a comprehensive guide to help you evict those pesky intruders from your walls.

Mice can be a real headache to deal with, and most of us don’t even want to think about it. From the droppings they leave behind to the damage they can do to your home, these little pests are a major pain. 

Things can get really tricky if they find their way into your walls. They’re tough to catch and can do a lot of damage to your home. Knowing how to get them out of your walls is important, but first, let’s figure out how they got there in the first place. 

How Do Mice Get Into Walls?

There are a few ways that rodents can get into your home and walls. The most common way is through holes and cracks in the exterior of your home. Mice and rats can squeeze through incredibly small spaces, so even a tiny hole can be an open invitation. Once they’re inside, they’ll start to build their mouse nest and have babies. 

Another way rodents can get into your home is through the vents. If your vents are not properly sealed, rodents can easily crawl inside and make their way into your walls. And finally, if you have any openings to your crawl space or attic, rodents can also come in through there.

Now that we know how they get in, let’s take a look at signs of rodents in your walls in order to determine if they are, in fact, present.

Signs of Mice in Your Walls

It can be difficult to tell if you have rodents in your walls, but there are a few signs that you can look for.

These are just some of the signs that you have mice in your walls. Dealing with mice in your walls is crucial for your family’s health and safety. Here are a few ways you can do that. 

5 Ways to Get Rid of Mice in Walls

When you have a rodent problem, you want to get rid of them fast and keep them gone! Use these tips, along with regular treatments from Fox Pest Control, to help you know how to get rid of mice and rats and keep them from returning.  

1. Seal Any Openings

First things first, block entry points by sealing any openings mice could use to enter your walls. Remember, these tiny rodents can squeeze through openings as small as a dime. Use caulk, steel wool, or expanding foam to seal gaps around windows and doors, cracks in your foundation, and other openings. Opt for materials that can withstand chewing. Adding mice-proof mesh over vents and other openings can also help keep them out.

2. Use Traps

The best way to get mice out of walls is to trap them when they come out to forage. Place traps in areas where you’ve spotted droppings, like cupboards or the garage. Snap traps are common and effective, but you can also use live traps if you prefer to release them far from your home.  

Traps can be a great way to catch rodents, but they do come with some downsides, especially if you have curious kids or pets around. And let’s be honest, cleanup isn’t exactly fun. If you decide to set traps yourself, be sure to place them in spots that are completely out of reach for little hands and paws.

3. Keep Your Home Clean

A clean, tidy home goes a long way in keeping little invaders out—especially the ones sneaking into your walls. Mice have a strong sense of smell and are always on the hunt for food and shelter. Leftover crumbs, open snack bags, and even a full trash can can be enough to lure them inside.

To make your space less appealing:

• Clean up food messes right away. Sweep up crumbs, wipe down counters, and don’t leave pet food sitting out overnight.
• Store food in sealed containers. This includes pantry items like cereal, rice, and snacks.
• Take out the trash regularly. Don’t let garbage pile up—especially in the kitchen.
• Declutter storage areas. Stacks of boxes, newspapers, and unused items create perfect hiding and nesting spots.

A little extra effort goes a long way. By removing easy food sources and hiding places, you make it a lot harder for mice to stick around—or even want to come in at all.

4. Don’t Forget Your Yard

Your yard is the first line of defense when it comes to keeping mice out of your home. A messy or overgrown outdoor space can be a welcome mat for unwanted guests. Mice often start outside before making their way indoors, so if your yard offers food, shelter, or easy access, you’re basically rolling out the red carpet.

Here’s how to make your outdoor space less appealing:

• Trim back trees and shrubs that touch or hang over your house—mice use them like highways to your roof and vents.
• Clear out clutter and debris, like leaf piles, firewood stacks, or unused equipment—these make great hiding spots.
• Pick up fallen fruit from trees and keep bird feeders away from your home’s perimeter.
• Secure pet food in airtight containers, and don’t leave bowls outside overnight.
• Stacked firewood can attract mice, so keep it at least 20 feet from your home and off the ground if possible.

By keeping things tidy outside, you’re helping protect what’s inside. A little yard maintenance now can protect against a much bigger headache later!
