It is frustrating, right? There are mice in your house, and they are keeping you awake at night. It is not the time to go full steam into a mouse control assault, but you need to be able to sleep.

In this post, I am going to run you through some actions you can do now to stop mice from getting under your doors.

How To Stop Mice Getting Under Your Doors In 5 Steps

Stop Mice From Getting Under Your Doors

Door Sweep/Draft Stopper

The first thing I would do is buy a draft stopper (see on Amazon).

They look like this:

Draft stoppers work by blocking off the area at the bottom of the door so nothing can get through… draft, mice, insects, etc.

If you want a product to help stop mice from getting under your doors, then you cannot go wrong with a draft stopper!

As a bonus, they stop other pests and drafts, too!

Check out these instructions for fitting this kind of door excluder to keep mice out of your room:


If you do not have time to wait for something to arrive, using a towel is my next go-to product!

I would actually use 2 towels. Start with one, and try to get as much of the towel under the door as you can. Leave no gaps!

Once you have a towel under the door, roll another towel up and place it in front of a closed door as you would a draft excluder.

Yes, you can use a towel under a door to stop mice, but you will need to squeeze it underneath and double up with the towels.

Sweep The Floor

The most important thing that you can do to stop mice from getting under your door is to ensure you clean up thoroughly.

Mice will absolutely squeeze under your door if they sense the smallest crumb on your floor! Ensure that you sweep up thoroughly not to leave any food out that will attract the mice.

Clothing Under Door Frame

Pick small clothing items and wedge them under your door when the door is shut.

When you think about the question ‘how do mice get under doors,’ the answer is ‘they squeeze under them.’ If you have objects in the way, the chances of a mouse squeezing under your door are greatly reduced, right?

This is similar to the towel option above, but the clothes you pick should be lighter material, which means they are more likely to fit in the gap between the door and your floor. You should opt for a door draft stopper for mice, but if you do not have one, then clothing will also work (but is less permanent).

Aluminum Foil

If you are getting desperate and nothing else is working, stopping a mouse from going under a door, you can crunch up some aluminum foil to push under the door. The aluminum will act as a barrier between rooms, dissuading the mouse from entering.

Some folks say that mice do not like to chew through aluminum foil, but I am not so sure (here are things that mice can chew through). I know that mice do not like chewing through wire wool, but I do not recommend putting that under your door! Especially if your floor is easily scratched.

Why Are Mice Squeezing Under My Door?

You have something they want

I mentioned it before in this post, but you need to ensure that you do not have anything in your room that attracts mice.

I am talking about crumbs, crusts, and bits of random food left on the side. It would help if you swept up all these things and placed them in the trash.

They are escaping

Do you have a cat in your home? A cat is an awesome way of keeping mice at bay, but they need to escape when they get in. If your door is closed, it means your cat cannot get in. Mice will see this as an opportunity to escape their predator.

Frequently Asked Questions

What can I do if mice still keep squeezing under my door?

If you have followed this post and are STILL getting mice squeezing under your door, it could indicate the gap is much bigger than you think. Are you sure the mouse is getting UNDER the door and not from another gap? Thoroughly check the room for common mouse entry points.

What mouse trap should I use for mice who squeeze under my door?

As you will be setting your mouse trap in a room, I recommend using a humane mouse trap. Avoid using a snap trap. Take a look at some awesome mouse trap options. Specifically the humane options.

The Mice keep coming back; how do I keep them away?

Ensure that you follow a complete mouse control guide. Clean up any food, and seal any mouse entry points. If a mouse cannot get into your home, then you will not have a mouse infestation, and they will not keep coming back.

How small should I make the gap to stop Mice from getting under the door?

The problem is that mice can squeeze through a hole the size of a pencil. I recommend that any holes should be smaller than a pencil. Even then, a smaller mouse may be able to get through.


I am confident that the tips on this page will help you if you are looking for ways to stop mice from getting under your door!

It is frustrating and concerning to know that mice can get anywhere in your home! Mice only need a very small entry point to gain access, and some doors will offer that opportunity.

I recommend you follow our ultimate guide for getting rid of mice so you can get rid of them and keep them out for good!
