How To Keep Mice From Coming Through Gas Fireplace

1. Find The Gap In The Fireplace

When learning how to get rid of mice in the fireplace, you have to start with the gaps. This is where mice come from.

They look for small gaps and seek warmth or food.

By finding the gap, they are going to continue to use this as a path back and forth. This is why finding the gap becomes important and it is common for this to be near the gas pipe.

Some fireplaces have large gaps in that part of the fireplace, so you will have to block it right away.

Until you do this, the mice will continue to enter the gas fireplace.

2. Use Steel Wool To Fill Gap

If you hear something in the chimney, it might be mice running around or other types of pests.

Don’t assume it is nothing.

The goal has to be to find the gap running along the gas pipe as that might be the main issue at hand. By finding the gap, you are going to have no trouble filling it using high-quality steel wool.

A simple fix such as this will go a long way.

The steel wool will deter the mice and keep them away from the fireplace throughout the day.

3. Inspect Other Parts of the House

Let’s assume the gap has been covered and you are satisfied with no mice being near the fireplace.

Does that mean you are good to go?


You will have to continue to look around the property and make sure the house is cleared. This is how you are going to take care of the pest problem at home.

Mice are clever animals and they will not stick out in the same spot. They will explore and that includes other parts of your house including your bathroom, kitchen, and/or bedrooms.

Look for these spots and make sure they are blocked too.

This will ensure you catch straggling mice that are still running around inside the house.

A simple fix here will ensure you don’t have mice running back and forth all the time. Just clear up the mess right now and make sure the mice are a thing of the past.
