Are you ready for a mouse battle? Do you need to rid your house of a mouse infestation? Are you fed up with hearing noises in your attic when you are trying to sleep? Do you need to set a trap to catch a mouse?

Before the battle begins, you will need to know how to set up a mouse trap!

In this post, I am going to run you through setting up a mouse trap, so you can stroll into the battle with the upper hand…

First things first, what equipment do you need?

Setting Up Your Mouse Trap – Equipment

Before you begin, it is important that you gather all the equipment you will need. 

  • Gloves – You do not get your scent on the trap. You will notice that I am not using gloves for the images on this post. This trap is not going to be used to catch mice, so I didn’t bother putting gloves on!
  • Bait – in this demonstration, I am using peanut butter to bait the trap. Recommended reading: The bait I use to catch mice.
  • Trap – Sure, you will need a mouse trap too! If you are stuck for which one to buy, check out my recommended mouse traps.

The picture above shows the most vital parts of a mouse trap. It is important to know each part before you can know how to set a mouse trap.

Add Bait To Your Mouse Trap

The next step you need to take to set a mouse trap is the bait application.

In this demonstration, I am using peanut butter. There are many things you can use as mouse bait, but peanut butter is always my ‘go-to’ food. It has never let me down.

In the trap above, I have added peanut butter as bait into the bait bucket.

Never overfill the bait bucket with bait.

Many people think that more bait means more success, this is simply not true.

If you add too much bait to your mouse trap, you run the risk of the trap not firing correctly. Over filling the bait bucket is one of the most common mouse trap mistakes!

You can see from the picture above that I have filled the bait bucket with peanut butter. Some peanut butter has spilled slightly over the edges but it will not interfere with the mouse trap functionality.

Place The Mouse Trap Down

To be as successful as you can be, you need to lay down your mouse trap in the best possible places.

When considering where to put your mouse trap, you need to understand the places that mice like to hide in your home. To increase the chances of a successful capture, it is best to start at these places.

Check out the pictures below to give you some direction:

You MUST lay down the traps before arming them!

Arm The Mouse Trap

Once your mouse trap is in place it is time to arm it!

This is where you need to be extremely careful. These mouse traps are designed to break the neck of a mouse. The springs are tight, and the force is enough to injure any appendage you are unlucky enough to catch in it!

This is how to set a mouse trap:


Whilst creating this, I thought it would be fun to show you a trap being triggered in slow motion!


The speed the trap comes down is incredible! I’ll say it again, please be careful when setting your mouse traps!

Checking The Trap

Assuming you have set it up and baited it correctly, and assuming that you actually have mice to catch, then there is a high chance that you will catch a mouse within 2 days.

It is important that you check the traps every 2 days to see if you have caught a mouse. Not only that but if you are using certain foods to bait the mouse trap, you may need to replace it.

There are some issues that you need to be aware of when checking your traps.

  1. Sometimes, traps can go missing. It is frustrating, but it might happen. I have detailed common reasons why mouse traps disappear right here.
  2. The mouse may still be alive. What do you do when you catch a live mouse in a trap? How do you dispose of a live mouse?
