How To Get Rid of Mice & Rodents in Walls

Posted September 12, 2022

You know that rodents can be a huge problem, and if you’re like most people, you probably don’t even want to think about it. From the droppings they leave behind, to the damage they can do to your home, rodents are just a big pain.

But, if you have them in your walls, it can be even worse. Not only are they hard to catch, but they can also do a lot of damage to your home. That’s why it’s important to know how to get rid of rodents out of your walls, and fast. But before we figure out how to get rid of mice in walls, let’s take a look at how they got there in the first place.

How Do Mice & Rodents 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 & Rodents 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.

Runs and Burrows

Although you won’t see the inside of your walls, you may see runs and burrows in exposed insulation in your attic or along the baseboards. These are paths that rodents use to travel from their nests to their food sources.

Also, if you have been wondering; can mice climb walls? The answer is yes. They are excellent climbers and can climb vertical surfaces with ease. So don’t be surprised if you find runs and burrows near the ceiling as well.

Foul Odor 

Another sign of rodents in your walls is a foul odor. This is caused by the urine and feces that rodents leave behind. 

Rodents also typically have a one-year life expectancy, so the foul smells could also be coming from a rodent that perished in your walls. If you notice a foul odor in your home, it’s a good idea to check for rodents. 


If you find a nest in your walls, it’s a pretty clear sign that you have rodents. Rodents will build their nests out of anything they can find, including paper, insulation, and fabric. You might find a nest in your walls, or you might find one in your attic or crawl space.


Droppings can often be found near food sources or in areas where rodents travel. They can also be found in nesting areas. If you see droppings in your home, it’s a good idea to call an exterminator.


If you hear strange scurrying or scratching noises coming from your walls, it could be a sign that you have rodents. They are often active at night, so if you hear noises in your walls at night, there’s a good chance that they’re caused by rodents.


Rodents can damage your home by chewing through wires, insulation, and drywall. These damaged wires are one of the leading causes of house fires, so make sure to check for damage so you do not put yourself and your family at risk.

These are just a few of the signs that you have rodents in your walls. That’s why it’s important to learn how to get rid of mice in the walls. Here are ways that you can do that.

5 Ways to Get Rid of Mice in Walls

1. Seal Any Openings

The first step is to seal any openings that rodents could be using to get into your walls. Look for cracks and holes in your foundation, gaps around windows and doors, and any other openings.

You can use caulk or expanding foam to seal the openings. Just make sure that the material you use is strong enough to withstand gnawing.

You may also want to install rodent-proof mesh over any vents or other openings. This will help keep rodents from getting into your walls in the first place.

2. Use Traps

One of the most common ways to get rid of rodents is to set traps. You can buy traps at most hardware stores, and they come in a variety of different types. The most common type of trap is the snap trap, which is a simple device that snaps shut when a rodent steps on it.

You can also use live traps, which are devices that capture rodents without killing them. These can be helpful if you want to release the rodents far away from your home.

Setting traps is usually the most effective way to get rid of rodents, but it can be dangerous if you have small children or pets. Make sure that the traps are placed in areas where they can’t be reached by children or pets.

3. Keep Your Home Clean

Another way to prevent rodents from getting into your walls is to keep your home clean. Rodents are attracted to food, so they’re more likely to enter homes that have food lying around.

Be sure to sweep up any crumbs, and don’t leave food out on countertops or in other areas where rodents can access it. You should also empty your trash cans regularly so that rodents don’t have a food source.

You may also want to consider getting rid of any clutter in your home. Clutter provides places for rodents to hide, so the less clutter you have, the less likely rodents will be able to hide in your home and walls.

4. Don’t Forget Your Yard

Remember that rodents can enter your home from the outside as well as the inside. Be sure to seal any cracks or holes in your foundation, and trim back any trees or shrubs that are touching your home.

You should also remove any food sources from around your home, such as bird feeders. And if you have a pet, be sure to keep its food in a sealed container. Also, pick up any fruit that falls from trees in your yard so that rodents don’t have a food source and prevent attracting different types of rodents.

Making sure your yard is clean and free of debris is important. This will make it less attractive to rodents and allow you to enjoy your yard without having to worry about unwanted guests.
