How-to Get Rid of Mice in The Walls – 2019 Step-by-Step Guide

Have you ever felt like someone or something was watching you? Have you ever walked around the house and felt like you were not alone? Can you hear sounds that make you realize that there is something within the walls? Well, not to scare you, but we have to tell you that your house is infested.

But wait! Don’t dial the exorcist just yet; it’s not a demon spirit from hell living within your walls, but rather something much worse: mice!

However, there is no need to worry, as this article will help you with all you need to know to get rid of those little pests. So without further ado, let’s get those mice out of your walls.

Key Signs of Mice Infestation

The signs of a mice infestation can be very subtle. Most of the time, you will not see a mouse but will just hear some noises. So how can you know for sure whether your house is haunted by a poltergeist or just infested with mice? The following signs can help you tell the difference.


No ghost would ever leave droppings around your house. A mouse, however, does not care about keeping your house clean. The droppings of a mouse can help indicate what you are dealing with. For example, they can tell you the size of the infestation and where the mice happen to be most active.


Look for gnawed holes. Holes made by mice are always small, about the size of a dime. A mouse will always gnaw the material clean through, so holes made by a mouse will always be clean cut.


You may find nesting material here and there. These materials include shredded paper, fabric, dead plant material, strings, etc. Mice use such items to build their nests. So, if you happen to find something like this and you have no idea where it came from, that is a strong indication that there is a mouse at work.


Another sign may appear on your food packaging. Mice may be merrily chewing away at your food packaging trying to get in. But in the process, they leave marks, which make it easier to identify that you have intruders inside your home.

How to Get Rid of Mice in the Walls

So, we know how to spot mice infestation, and we have confirmed that it is, in fact, a mice infestation and not a restless spirit. Therefore, the next step is very important, and that is getting rid of the mice in your walls. So, let’s get straight to it. 

Determine Entry Spots

They must be getting in from somewhere, right? The first step that you need to take is to identify all the potential openings. These openings can be very, very small. In fact, they might seem insignificant to you, but they are more than enough for a mouse to squirm their way in. So, look for small cracks or gaps between the doors or even that tiny little space between vents and windows. 

Garages are another favorite place for mice. So make sure that your invaders are not coming in from there. 

Set Up Mouse Traps

The best ally you will have in the war against mice will be mouse traps. There are several different kinds available in the market. You can find old school traps that snap. However, mice of the 21st century are much cleverer and faster than their ancestors. So, for these pests, you can opt for an electric mouse trap that kills the mouse without making a big mess. Another great thing about these traps is that you do not have to see or touch the kill. You can dispose of it quickly and efficiently. Other traps also use chemicals and poisons, but that can be dangerous. 

Close Access Points

When dealing with persistent foes, such as mice, there can never be a dull moment. To ensure that your infestation is completely dealt with, you need to be thorough. Mouse traps will rid you of the mice that are already in, but we need to stop other ones from getting in again. This means we have to close up all the access points that we have identified in the first step.

Even if one access point remains, it will act as an open invitation to the mice. And if there is one thing we know about mice, it’s that they never reject an open invitation. 

Clean Your House

Clean places automatically discourage mice from visiting. When you clean up your house, you effectively take away their playground. You take away their hiding spots, and you take away potential materials they could use to make their nests. 

In addition to that, be sure to clear out your storage areas and garages. Get rid of the unnecessary clutter that could give shelter to mice. When your living space and storage areas are clean, it will become harder for these troublesome critters to go undetected. 

Getting Rid of Mice in Your Walls - Video Guide

The video below offers further insight on how to deal with mice in walls or under houses. The video recommends the use of mothballs. They are easy to get and inexpensive. Since mothballs have a strong odor, they can scare mice and other rodents away. The reason behind this is because these rodents have a very sensitive sense of smell. You only need a small amount to scare them off. 

However, you must be careful and not use these mothballs very often as they could have an adverse effect on humans as well. 

How Do Mice Get in Walls?

There are various ways that mice get inside the walls of your home. Let’s take a look at the most common entryways that mice use to infiltrate your home:

Cracks and Gaps

This is perhaps the most common route taken by mice. Cracks and gaps can be anywhere – walls, ceilings, windows, vents, doors, etc. These allow mice to get inside and live within the walls undetected for a long period of time. 


Openings around pipelines serve as another way for mice to get in. It’s not like they use one specific type of pipeline; rather, they can use sewage pipelines, utility pipelines, and so on to get in and out. Never forget to seal your drainage pipes properly or else the mice will come through your sinks and even bathtubs. 


Some mice even come with a long-term plan. They get into the garage first, and they have many ways to do that too. After some time, they can move into the walls via holes and cracks. Walls for mice are definitely safer than garages; that is why they decide to make their home there.


All in all, never let the small differences you feel in your living space go unnoticed, whether it be the unusual sounds, the musty smells or the random gnaw marks and holes. The best way to deal with an infestation is to catch it at its earliest stage. So if you feel like you have mice living in your walls, follow what we have learned today and hopefully, you will find success in your conquest.
