How to Get Rid of Mice in The Garage – 9 Step Guide

Here is the 9 step process if you want to know how to get rid of mice in the garage.

The key message here is that it takes time, and some excellent notes (taken in steps 1 and 2) to get rid of mice in your garage! You should not expect to have a mouse free garage straight away.

Before you begin, you should always be protected when entering an enclosed environment where mice have been. At a minimum, I have a respirator on. It stops any poop and urine particles from getting into my lungs. I’ll also have some strong gloves and some protection for my feet.

Ensure that your clothes are washed when you have finished too.

Good luck!

Identify Entry Points

The first thing you need to do is figure out how the mice are getting into your garage. Make a note of each valid entry point, because you will be sealing it up further along in the process.

This step is purely to identify these points, not to do anything with them.

I recommend that you read this post about common mouse entry points because it covers everything you need to know.

Record Mouse Activity

The next step is to make a note of where in your garage you have noticed mouse activity.

Record every place you have seen mouse droppings or mouse urine, and any place you can see a nest. If you have seen or heard a mouse, make a note of that too.

You are going to use these details when setting traps, and they will also be useful for cleaning afterward!

Choose Your Weapons

Now is the time to decide whether to use traps, poison, or both to catch the mice!

My preference is to use traps only, or poison with traps that contain the mice until the poison has worked.

You should always use quality mouse traps for a higher success rate.

Consider using traps that catch multiple mice if you think you are dealing with an infestation.

Get The Bait Ready

It is time to prepare the mouse bait! You should go for peanut butter first.

There are plenty of other mouse bait options too.

If you find that one bait is not very successful, you should move onto the next. I’ve never met a mouse who is a picky eater, but they might exist in your garage!

Decide Where To Place The Traps

If you want to know how to get rid of mice in the garage, then you need to know the best places to put mouse traps.

This is where your knowledge from steps 1 and 2 come into play.

Make a note of the best places to put your mouse traps, but don’t put them down just yet.

Seal Entry Points

Now is the time to seal those entry points!

We do not want any more mice to get in at this time. I suggest doing this at sunset if you can. There is more chance that the mice are out looking for food as this is when they become more active.

If the mice are out of your garage, and you seal up the entry points, then they will not be able to get back in, which is awesome news!

Set The Traps

Ok, you have sealed the entry points, you have your mouse bait ready, and now is the time to set them down!

Setting mouse traps needs to be be done correctly to increase the chances of success.

If you do not set the traps correctly, you could end of with missing mouse traps or missing bait!

Check The Traps

Now that you have the traps laid down, it is time for you to leave them to work. Try to visit your garage as fewer times as possible. This will give the opportunity for the mice to come out and stumble upon the traps.

You should be checking the traps every 2-3 days to see if any mice have been caught.

If you have caught a mouse, get rid of the dead mouse, clean the trap, and set it back up again to catch more! The job is not over until you have confirmed the next step…

Quick note – if you catch a live mouse, you need to dispose of it correctly!

Confirm The Mice Have Gone

The final step is to check to see if all the mice have gone!

If you have confirmed this to be the case, then you have won your battle against the mice! You wanted to know how to get rid of mice in the garage, and now you have done it… congratulations!

Now that you have got rid of the mice, and seal their entry points, you should not get any mice back in. To strengthen this position, don’t forget to perform regular checks around your home for any new entry points.

Cleaning Up

Once you have confirmed that all of the mice have gone from your garage, you can begin the cleanup process. You should be completing the following tasks:

  1. Clean mice urine
  2. Clean mice poop
  3. Destroy and clean areas used for nesting
  4. Dispose of gnawed items

If you have had mice that have died in your garage, you need to follow the correct process for getting rid of a dead mouse and smell!
