Why Do Mice Like the Basement?

Mice are attracted to basement living because they like dark, warm environments.

Your clutter will also serve as excellent hiding places for mice and give them plenty of things to chew to keep their teeth healthy. Mice can also use your clutter can also be used as nesting materials.

All these hiding places are appealing because they also offer shelter from the predators outside, such as birds and foxes. The basement environment is excellent for nesting, and before you know it, you’ll have hundreds.

Your basement also provides easy access to the outside through vents, pipes, or external doors and is probably close to where you keep the trash, so they have a full menu of your leftovers each day.

Mice will already know these entry points because it’s probably how they got into your basement in the first place.

How to Get Rid of Mice from Your Basement

If you’ve noticed mice in your basement, there are a few different ways to tackle the problem.

Getting rid of mice in your basement will take some cunning and time.

1. Ultrasonic Mouse Repellers

If you’re looking for a mouse-friendly option, using sound to put the mice off your basement is an excellent option. Instead, you set up the device in your basement, and it emits a high-frequency buzz every few minutes.

The sound is very unpleasant for mice but is undetectable to humans. This means that it will drive the mice away to find somewhere a little quieter while you won’t notice anything.

It’s practical and has the positive that the mice won’t be harmed. However, it could affect your other pets, should they be close enough to the sound, as their hearing is much more sensitive than ours.

The repellers also work using an electronic cord, so you’ll need to ensure this is out of harm’s way. For example, a mouse could try to outsmart you by chewing through it.

2. Battery-Powered Traps

Battery-powered traps are a more humane way of disposing of mice than the traditional trap set up.

You will need to put some food inside a covered chamber.

The mouse will smell the bait and wander in to take a look. Once the trap senses the mouse in there, it will deliver a high-voltage electric shock which will kill the mouse instantly.

It’s an easy way to kill the mouse without causing it pain, and the battery-powered setup means there are no wires that the mouse could chew.

However, each trap will only kill one mouse at a time, so you’ll need a few throughout the basement, and you will need to keep checking and emptying the trap. If there’s already a dead mouse inside, other mice will stay away.

3. Snap Traps

Snap traps are the traditional form of mouse trap seen in all cartoons. The piece of cheese is placed on the end, and a metal bar is clamped down on the mouse when they try to take it.

These mouse traps can kill instantly if set up correctly, so it’s not as inhumane as people think.

However, it is seen as the riskiest form of mouse trap today because of how the trap is set. It’s all too easy to get a finger stuck under the bar or a pet to tread on it.

However, they’re perfect for basement use if children and pets don’t venture down there.

As with the battery-powered traps, you will need to check them regularly and remove the bodies of the mice; otherwise, getting rid of the whole family could be a slow process.

4. Peppermint Spray

Unlike us, mice and rats hate the smell of peppermint. One of the most effective and humane ways to drive away a mouse infestation is to spray your whole basement with peppermint oil mouse repellant spray.

The smell will keep them away, making your dingy basement smell fresh and amazing.

5. Poison

Not the most animal-friendly way to get rid of your mouse infestation, but it is effective.

Mouse poison-controlled boxes can be purchased cheaply online and operate using a pre-baited system.

You pop the boxes around your basement and wait for the mice to go in and check out the tasty snack, which is already laced with poison.

The boxes are fully covered with a locking mechanism, so it’s safe for children and pets. However, you will need quite a few boxes to clear a large infestation and will need to check and remove any bodies regularly.

When using poison to kill mice, I always ensure the mine are trapped when they consume the poison; I don’t want them dying in a wall space where you can’t get to the body!

How to Keep Mice out of Your Basement

You’ve learned how to remove mice from your basement, and you’ll need to make sure they stay out.

  • Declutter – Most people will use their basement for some storage. The problem is that’s the biggest “vacancies” sign for mice. So clear up your clutter, so there are no attractive hiding places.
  • Seal your trash – Open bags of trash, especially food, are very inviting for a hungry mouse. Seal all your garbage bags and make sure they’re off the floor.
  • Cover any external entrances – Mice can get into your basement through even the tiniest holes. If you notice a hole in the exterior wall, seal it up with expandable foam, or steel wool. Use weather-stripping on gaps around doors and windows. These are common mouse entry points, and sealing them up is the best way to prevent mice from getting in.
  • Clear up your pet food – If you have a pet, the smell of their food will attract mice. Ensure that you clean up your pet’s leftovers as soon as they’re done eating.


Having mice in your basement is a common issue and nothing to be ashamed of.

However, you must get them to move out quickly to maintain the hygiene and structure of your home. If you don’t sort it quickly, you could have a mouse infestation.

Remember that keeping the mice out of your home is just as important as removing them. So don’t waste all your hard work by inviting them back in.

If you’re not confident in dealing with the problem yourself, you can always enlist the help of a pest control expert to help. They cost a lot more than DIY rodent control, but it can be worth it.

Good luck!
