Why Do Mice Hate Spearmint Oil?

Mice have a strong aversion to the smell of spearmint, making it an effective repellent. The menthol aroma of spearmint oil irritates their noses, making them steer clear of the area. According to research, essential oils with a strong scent, like spearmint, disrupt the scent trails these little rodents use to navigate through your home.

In fact, researchers at Cornell have shown that essential oils containing menthol repel vertebrates like mice.

Now, you might be wondering, how do I use spearmint oil to keep mice away? Simple! You can either dab spearmint oil on cotton balls and strategically place them around the house or create a spray by mixing a few drops of oil with water. We’ll give you the full details on how to use spearmint oil to repel mice below.

DIY Spearmint Oil Spray Repellent

First and foremost, you need to get your hands on some high-quality spearmint oil. I personally use this Handcraft Spearmint Essential Oil. It’s 100% pure spearmint essential oil and even comes with a built in dropper for easy use. Once you have the oil, the fun part begins!

To make a spearmint oil repellent, all you need are a few simple items: spearmint essential oil, a spray canister, cotton balls, and water. Here’s how to create your own repellent:

  1. Fill your spray canister with water and add a few drops of spearmint oil. I usually recommend around 5–10 drops per cup of water.
  2. Shake the canister well to mix the oil and water.
  3. Spray this mixture around the entry points of your home, like doorways and windows. This will help to deter mice from entering your home.
  4. Diffuse spearmint oil in areas of your home that need extra protection!

Alternative Application Methods

Here are a few other ways to use spearmint oil!

  1. Cotton Ball Method: Dab a few drops of spearmint oil on cotton balls and strategically place them in common mice hideouts, such as drawers, cupboards, and near small openings.

Make sure to replace the spearmint-soaked cotton balls about once a week, as the scent may lose its potency over time.

Here are some additional tips to make your home less inviting to mice:

  • Store your food in airtight containers.
  • Keep your kitchen clean and free of crumbs.
  • Seal up any cracks or holes in the walls, floors, and foundation.

Effectiveness of Spearmint Oil Vs. Other Essential Oils

Comparison with Peppermint Oil

Let’s start by comparing spearmint oil with its close cousin, peppermint oil. They may seem similar, but you’ll find that their strengths in repelling mice differ quite a bit.

Although both oils contain menthol, peppermint oil has a much higher concentration! In fact, peppermint oil is seen as one of the best oils to use for a diy mouse repellent! This means it’s often thought to be more potent in deterring mice.

The great thing about the scent of peppermint is that you can find it in so many different products that will work to repel mice! For instance, you can use it in mouthwash form and even in candy form like with altoids!

Now, let’s compare spearmint oil with other essential oils known to repel mice:
