Mice have sharp teeth and chew on nearly anything your house offers. From the tiniest granule of food to the most pointed shards of glass, you name it!

Naturally, you look for the cheapest and most optimal solution to repel them because you wouldn’t want to live in a mouse-infested house.

It’s been observed that some mice despise a few scents. Irish Spring soap has scent variants that include those that mice dislike. But does Irish Spring soap keep mice away?

How Effective Is Irish Spring Soap in Getting Rid of Mice?

Lots of people have talked about their use of Irish Spring soap for mice. You see it on any social platform, such as YouTube, Reddit, TikTok, Facebook, and so on.

Frankly, there’s actually no direct answer to this question since there are many variables to consider:

Do all types of mice eat soap? Are there specific brands and kinds of soap that mice can’t stand? Is it the scent of the soap that these critters loathe or its inedibility?

Currently, we do not have enough scientific substantiation on whether methods of using Irish Spring soap repel mice or not.

However, ample informal evidence gives us some degree of clarity on its effectiveness. Some people attempted to use Irish Spring soap and rats were presumably gotten rid of.

To understand how we may keep mice away with Irish Spring soap, we must first know if mice consume soap and the aromas that they possibly find distasteful.

Do Mice Eat Soap?


Mice are attracted to a wide variety of food, like meat, grains, plants, or even leftover meals. But mice also nibble on wood, plastic, rubber, and other non-food items.

They typically use their olfactory senses to detect food. Although artificial, most of the fragrances applied to soap products mimic that of fresh fruits, flowers, plants, and the like.

On top of that, animal fat is sometimes one of the compositions of soap, along with olive oil, soybean oil, and canola oil.

That is why it is probable that some mice consume soap, thus resulting in people using soap as a mouse repellent.

How to Repel Mouses With Irish Spring Soap


Rather than expensive and foul-smelling pesticides to repel mice inside your house, using Irish Spring soap repel rodents prove to be easy and cheap.

  • Grate the bar or bars of Irish Spring soap until you get enough shavings to cover the areas you intend to place the repellent on.

If the soap bar is difficult to grate, you can try warming it up by exposing it to a heat source.

  • Scatter the Irish Spring soap shavings on areas that you don’t want mice to infest or on areas where mice are usually found.

Once you have placed the shavings in the areas you wish to keep mice away from, you may have extra shavings left.

To use this in the future, store the remaining shavings inside a plastic bag to prevent the soap from absorbing moisture, which can turn the shavings into a mushy paste.

What Scents Do Mice Hate?

We still cannot claim that mice hate Irish Spring soap specifically, but there may be something about the soap that does not sit well with rats– like its scent.

Mice have a well-developed sense of smell. This helps them know which area the food is located in your house. Aside from that, mice can also smell the components of non-food objects that make them want to chew on them.

Mice tend to stay away from certain fragrances, like mint, cedar, and eucalyptus. Irish Spring soap has variants that include those scents, like their Hydrating Eucalyptus and Mint or their Sage and Cedar variants.

Here are the five scents that mice generally do not like and how to use them to repel mice:

1. Peppermint


Peppermint is first on the list, as it is generally recognized to repel mice. The minty smell of peppermint oil is unappealing to mice.

  • How to use peppermint to repel mice:

Drop a sprinkling of peppermint oil on cotton balls. Place these in areas where mice are likely to stay or those places you want mice to keep away from, like in the dining room, kitchen, or basements.

2. Eucalyptus


Leaving your kitchen or house with the smell of eucalyptus oil will keep it fragrant for you and your family while naturally preventing mice from residing in your home.

  • How to use eucalyptus to repel mice:

Add two teaspoons of eucalyptus oil and a small amount of liquid soap or detergent for every one cup of water. Spray this liquid solution to different places in your house, especially the kitchen to keep mice away.

3. Cedarwood


As its scent is displeasing for rats, cedarwood oil smells like that of woods and is toxic for rodents.

  • How to use cedarwood to repel mice:

Get some cedar chips and place these in the areas or corners of your house where you observe the presence of rodents.

4. Capsaicin or chillies


Capsaicin is what makes peppers piquant. The same component also repels mice as their tongues can’t probably tolerate its spiciness.

To try this, you can use pepper, hot sauce, chili powder, chili oil, chilies, and other spicy condiments.

  • How to use capsaicin or chilies to repel mice:

Scatter the spicy condiment on areas where mice are typically seen going around. Since mice also like to insert themselves in small places, you may also drizzle a little bit of this condiment on those areas.

Chili powder also keeps them away as it would burn their noses when they sniff it.

5. Cinnamon


Lastly, rodents hate the smell of cinnamon as it has a powerful, tangy odor. Other than that, you likely already have some cinnamon stored in the kitchen for cooking!

  • How to use cinnamon to repel mice:

Cinnamon comes in different forms and types, like Ceylon cinnamon and Cassia cinnamon. These are usually pulverized, but there are also cinnamon sticks and oils.

Regardless of what type of cinnamon you have available, rats despite its smell. So drizzle or place cinnamon on the locations where mice often visit.


When we leave food or clutter lying around, our houses serve as a source of sustenance for mice. This leads them to reside in our homes.

Why else would we ponder the question, “Does Irish Spring soap keep mice away?” if we do not intend to find cheap and effective methods to prevent rats, mice, or any other rodent from lingering around our houses, right?
