Spearmint and Its Properties

Mentha Spicata

Mentha spicata is the scientific name for spearmint. This hearty herb is a part of the large mint family, and it packs a punch in terms of scent! This vivacious plant not only adds a refreshing aroma to your garden or home, but it is also a secret weapon for keeping mice at bay.

Mint Family

The mint family is full of plants with aromatic properties. Yet, among all these plants, spearmint really stands out when it comes to repelling mice. Why, you ask? It’s all in the scent. Mice have a keen sense of smell, and it is said that the pungent aroma of spearmint essential oil overpowers their senses. It’s nature’s way of saying, “Not today, rodents!”

Spearmint contains menthol just like other members of the mint family such as peppermint. Researchers from Chulalongkorn University have shown that plants containing menthol can repel rodents like rats and mice. When applied, menthol plants can greatly decrease the amount of time rodents spend in an area.

Essential Oil

No need to plant an entire spearmint metropolis around your home, though! Essential oil extracted from spearmint leaves offers a concentrated, long-lasting way to deter mice. A few drops here and there near potential entry points can work wonders in keeping those furry intruders away.

Some additional tips for using spearmint essential oil:

  • Place small pots of spearmint plants around your house, both inside and outside, to provide an extra barrier.
  • Grow other potent plants, like peppermint, as extra reinforcements in your crusade against mice.

Utilizing spearmint plants and essential oil can be an effective naturally defensive method against mice!

Mice and Why They Hate Spearmint Plants

As a devoted gardener like yourself, I know the struggle of dealing with pesky rodents in our beloved yards! Common rodents such as mice have a keen sense of smell and are attracted to compost, seeds, and other sources of food. Luckily, there’s a natural way to combat these unwelcome visitors: spearmint plants.

Sense of Smell

Mice, just like many rodents, rely on their sense of smell to navigate and find food. You’d think a delicious-smelling spearmint plant might tempt them, but quite the opposite: they find strong scents highly unappealing. So instead of using harmful chemicals or traps, try a natural mouse repellent like spearmint plants!

Aversion to Strong Scents

Why are mice repelled by the robust aroma of spearmint plants, you ask? Well, to put it simply, this strong scent interferes with their ability to find food and other mice. With their powerful sense of smell disrupted, mice find it hard to pick up on other scents, making your cherished yard a less attractive home for these unwelcome critters.

Entry Points

Did you know that mice can squeeze through openings as small as a dime? It’s true! By strategically planting spearmint around your home’s entry points (such as doors and windows), you can make it less inviting for mice to enter your home. Think of those minty plants as a barrier to unwanted wildlife!

Of course, spearmint plants aren’t the only option you have at your disposal. A variety of other plants can help discourage mice and maintain a rodent-free yard. For example, mice also dislike peppermint and wintergreen. Ultimately, all you need is to find the plant that works best for you and your situation.

Using Spearmint to Repel Mice

Spearmint Plant Placement

If you’re tired of mice intruding into your territory, try using spearmint plants to safeguard your home! Mice absolutely dislike its scent. Planting spearmint around your garden and near your vegetables can act as a natural pest control barrier. Strategically place spearmint in containers around your yard and near entry points, to help keep mice at bay.

Spearmint Leaves and Oil

Spearmint oil is closely related to peppermint oil, and though not as potent, it can still be effective for repelling mice. You can experiment with fresh spearmint leaves or oil to achieve similar results. Rub spearmint leaves or oil onto surfaces or cotton balls and place them in areas where mice might be attracted to.

High quality, pure spearmint essential oil is more effective than low quality products. We recommend this Handcraft Spearmint Essential Oil. It’s 100% pure which will give you the best results when it comes to repelling mice.

Spraying Solutions

Creating a spearmint spray solution can be a handy and efficient way to deter mice. In a spray bottle, mix 5 parts water and 1 part spearmint oil. This mixture is convenient: you can keep it under the sink or in your garage to spray areas where you suspect mice may want to enter. Remember, consistency is key! Your home will smell like a spearmint wonderland and the mice will scurry away!


Craving an “au naturel” air freshener? Spearmint sachets can serve a dual purpose – repelling mice and refreshing your home. First, grab some small cloth bags. Fill these sachets with spearmint leaves or oil-soaked cotton balls, and place them strategically throughout your space. Not only will your home smell amazing, but it’ll also be a no-mouse zone!

Other Plants That Repel Mice and Pests

As someone who wants to use natural methods to repel mice, let me share with you some other plants that can help keep these pesky creatures at bay. In addition to spearmint plants, there are more options you can explore to protect your home from mice and pests!


Peppermint is an aromatic plant that is quite effective in repelling mice and pests. Did you know that mice can’t stand the strong smell of peppermint? This smell is potent and refreshing to us, but to mice and pests, it’s unbearable! To prevent mice using peppermint plants, you can:

  • Plant peppermint around your home’s boundaries.
  • Place cotton balls with a few drops of peppermint oil near the potential entry points of mice.
  • Keep peppermint essential oil near food storage areas.


When it comes to plants that mice dislike, let’s talk about lavender. This lovely purple plant is not only a delight for the eyes, but it also helps keep mice away. Its scent is pleasant to humans, but a deterrent for mice and other pests. You may consider:

  • Growing lavender in your garden to create a mice-free zone.
  • Placing dried lavender sachets in your pantry or closet.
  • Creating a lavender spray with essential oil and water.


Garlic might be an essential ingredient in your kitchen, but guess what? Mice aren’t fans of this strong-flavored plant! Garlic emits a pungent smell that is unbearable to these small creatures. To utilize garlic plants in mouse prevention, consider:

  • Planting garlic cloves around your yard.
  • Placing crushed garlic cloves near possible mouse entry points.
  • Sprinkling garlic powder around suspected infestation areas.


Another great plant to repel mice is sage. You might be familiar with this herb for its culinary and medicinal uses, but sage can also deter mice because of its fragrance. Who knew keeping mice away could be this fragrant, right? To use sage in repelling mice, you can:

  • Plant sage strategically around your garden and home’s perimeter.
  • Place dried sage leaves in closets, pantries, and other areas where mice are likely to hide.
  • Mix sage essential oil with water to create a repellent spray.


Lastly, let’s talk about onions. Just like garlic, onions have a strong scent that mice absolutely despise. The sharp aroma of onions is off-putting to these little creatures. As a result, onions can be utilized as a natural rodent repellent. Some ways to use onion plants for rodent prevention include:

  • Planting onions around your garden to keep mice away.
  • Chopping an onion and placing it near potential mouse entry points.
  • Grating an onion and sprinkling it along walkways or around the house.

Plants, including spearmint, can help keep mice away from your home in an eco-friendly manner. Give these options a try, and enjoy a mice-free home, naturally!

Cautions and Considerations

When it comes to using spearmint plants to repel mice, there are a few things you need to keep in mind. In this section, we’ll discuss the invasive nature of spearmint and some other aspects to consider when using it as a natural mice repellent.

Invasive Nature of Spearmint

Spearmint, a member of the mint family, is known for its invasive growth habits. This means that once you plant it in your garden, it might spread more than you desire! So, if you’re planning on introducing spearmint as a mice deterrent, be prepared for it to potentially take over a portion of your garden.

To keep the growth in check, you can plant spearmint in pots or containers, which will restrict its spread. Alternatively, you could plant it in designated areas of your garden, away from other vegetables or herbs that you are growing.

Remember, your goal here is to focus on using natural methods to deter mice from your home and garden. With spearmint and other plants, you can create a barrier that’s not only non-toxic for your pets but also adds some greenery to your space!


Spearmint plants can be an effective natural method to repel mice from your home! Mice have an aversion to strong smells, like the one emitted by spearmint plants. So, planting these aromatic herbs around your house can keep the little critters away.

To make the most of spearmint’s repelling powers, try these tips:

  1. Surround your home with spearmint plants in pots or garden beds.
  2. Place spearmint sachets inside drawers, cabinets, and other spaces you want to keep mice-free.
  3. Create a spearmint-infused spray to apply in areas where you’ve noticed mice activity.

It’s important to remember that mice enter your home in search of food and shelter, so make sure to keep your space clean and free of easily accessible food sources. This way, you’ll discourage them from staying even if they manage to sneak in.

There are other plants that can help repel mice too, such as lavender, peppermint, or eucalyptus. Consider combining them with spearmint for a more effective approach and a harmonious garden.

So, to all the nature and wildlife enthusiasts out there, remember: spearmint plants can be a powerful ally in your battle against mice! Embrace this natural solution, enjoy a mice-free home environment, and let the scent of spearmint plants charm your senses and repel those pesky rodents.
