Understanding Catnip And Why Mice Hate It

Nepeta Cataria

Catnip, scientifically known as Nepeta cataria, is a perennial herb belonging to the mint family. You might be familiar with its fame amongst our feline friends, but did you know that it’s also a savvy solution for keeping mice at bay?

One of the key essential oils in catnip is called nepetalactone. This compound is renowned for its ability to attract cats and, funnily enough, repel mice!

Brigham Young University tells us that catnip can also repel flea beetles, Japanese beetles, aphids, squash bugs, ants, and weevils. It’s an all-around amazing repellent plant! In fact, an article from the Recent Developments in Invertebrate Repellents stated that nepetalactone is more effective in repelling mosquitos than DEET!


Nepetalactone is a volatile organic compound found in Nepeta cataria and it’s this chemical that gives catnip its unique dual action (attracting cats but repelling mice). So, how do you put this knowledge to work in your quest for a mouse-free home?

For indoor use, consider placing fresh catnip leaves near suspected rodents’ entry points. Mice will detest the smell and think twice before sneaking around in your home! Double the benefit if you have a cat since they will love playing with the leaves.

Nature Tea’s Catnip – Dried Nepeta cataria Loose Leaf/Buds are great for placing near entry points.

Another creative way to use catnip indoors is to make a catnip sachet. Simply fill a small cloth bag with dried catnip and place it in cabinets, closets, or any other areas where mice might be hiding.

You can also try the following:

  • Planting catnip in hanging pots near windows or doors, and let its aroma work as a natural deterrent.
  • Making a catnip spray by steeping the leaves in boiling water, then straining and spraying the liquid around your home’s vulnerable places.

However, always remember that this solution is to be used only with catnip as a plant. It’s important to remember that the focus is on utilizing catnip indoors, but these methods can be used as inspiration for both indoor and outdoor applications.

Using catnip as a natural repellant is an environmentally friendly way to tackle your mouse problem, without resorting to harsh chemicals or inhumane traps. Embrace the power of Nepeta cataria and say goodbye to unwanted furry intruders!

Pot and Container Options

Homeowners, rejoice! Your natural mouse-repelling solution is just a catnip plant away! With its scientific name, Nepeta cataria, catnip has a compound called nepetalactone that repels mice effectively indoors. Here’s how you can use this wonder plant in your home:

First, let’s look at pot and container options. You’ll want to choose a pot that’s both functional and decorative.

  • Ceramic pots: These provide a timeless and stylish look while promoting healthy root growth for your catnip plant. 🌱Laerjin’s Flower Pots with Drainage Holes and Saucers are a great choice for your catnip plants!
  • Plastic containers: Lightweight, affordable, and perfect for those who want to save a dime without compromising on functionality. 💰
  • Fabric pots: A great choice for those that value air circulation and promoting robust plant growth!

Catnip Spray

Now let’s talk catnip spray! Why buy when you can DIY? It’s simple, budget-friendly, and perfect for a quick fix.

Here’s what you need:

  • Fresh catnip leaves: Also known as the main ingredient! 🌿
  • Distilled or boiled water: This ensures that the spray is safe and free of contaminants! 💧
  • Spray bottle: Choose a bottle size that suits your needs – a small one for spot-treatments or a larger one for wider coverage. 🧴

Here’s how to make your indoor mouse-repelling catnip spray:

  1. Chop up fresh catnip leaves into smaller pieces.
  2. Steep the leaves in hot distilled or boiled water for 10-15 minutes.
  3. Strain the liquid to remove leaf bits, and pour the catnip extract into your spray bottle.

Now you’re ready to spray! But where? Identify spots like small gaps, crevices, and the base of walls – areas where mice are known to enter. Spray the catnip extract onto these spots, and watch your home become a mouse-free zone!

Just remember to reapply the spray regularly, since the repelling effects of nepetalactone will weaken over time.

Benefits of Repelling Mice Indoors With Catnip

Catnip, a natural remedy, can be an effective solution to repel mice in your home! The plant’s strong scent disturbs the rodents’ sense of smell, making it a natural and safe alternative to harmful chemical treatments.

So, let’s dive into various ways to use catnip to keep those pesky mice at bay without harming them or your home environment.

Firstly, plant some catnip seeds in small pots and strategically place them around your home, especially near areas where you’ve spotted mouse droppings. For instance, put one near your garage entrance to keep mice from coming indoors. This practice will not only repel mice but also make your home look green and inviting!

Another creative way is making sachets filled with dried catnip leaves. You can place these sachets in your cupboards, closets or pantry – wherever you’ve noticed mice activity. While the catnip works its magic on the mice, it remains harmless to humans.

Along with mice, catnip can help repel other pests like ants, roaches, mosquitoes, and even termites – making it a multi-purpose natural remedy! Though we’re focusing on indoor catnip usage for mice, it’s great to know it has other benefits as well.

Remember, the key to effective catnip use is consistent replenishment. Monitor the plants, and if they seem to be losing their potency, replace them with fresh catnip. Regular care and attention go a long way in keeping your home free of unwanted rodents!

In conclusion, utilizing catnip indoors is an eco-friendly and safe option for repelling mice and other pesky insects. Don’t let those pesky rodents have free rein in your home anymore; give catnip a try and see the difference it can make!

Moving on, lemongrass can show mice who’s boss with its fresh citrusy scent and insect-repellent properties. Don’t forget the lovely lavender either.

Mice problem in your house? Considering natural methods to repel these pesky creatures? Catnip is the answer! But first, let’s find where they’re coming from.

Entry points are crucial to tackle a mouse infestation. Check for cracks in walls, gaps near pipes, and holes around your home. Seal any identified entry points using caulk or steel wool. This helps significantly in preventing future mouse visits.

Call an Exterminator

If you’re facing a severe infestation, it’s time to call a pest professional. While catnip can help, a stubborn infestation may need more potent solutions.

Additional Considerations To Keep Mice Away

Household Cleanliness

Let’s start with a clean slate! Itch no more, because ensuring good household cleanliness is an essential factor when using catnip indoors to repel mice.

By eliminating accessible food sources, such as crumbs, leftovers, or pet food, you can make your home less inviting to rodents. Remember, even small steps, like taking out trash regularly and storing food in sealed containers, can make a big difference.

Moreover, pay extra attention to areas like your garage or backyard, as these are prime hiding spots for unwanted guests.

Pets and Catnip

When it comes to sharing your abode with four-legged friends, using catnip can be both a blessing and a cat-ch! If you have feline companions, they might not only find the catnip irresistible, but it may also offer them natural entertainment.

However, be cautious around other animals, like dogs, for whom catnip holds no attraction. Simply placing the plant in strategic locations may not deter mice from invading certain spaces. Be sure to monitor your pets and balance their interaction with catnip while still aiming to ward off rodents.

Invasive Catnip Growth

Though catnip is an organic and natural solution for repelling mice indoors, you need to keep a keen eye on its growth. In some areas, catnip can become invasive in your garden, nabbing valuable space and resources from other plants.

To prevent this, consider growing catnip in pots indoors and strategically placing them in areas where you’ve previously spotted mice. This way, you make the most of this “meow-nificent” herb without risking an unruly invasion.

By maintaining household cleanliness, being mindful of your pets when using catnip, and controlling invasive growth, you can effectively utilize catnip as a natural solution to repel mice indoors. Good luck, and may your home be rodent-free!

That’s All For Now!

Using catnip indoors to repel mice is an effective and natural solution to a common household problem. Catnip contains chemical constituents such as nepetalactone that are known to repel mice, making it a safe and humane alternative to harsh chemicals or traps.

Additionally, catnip is easy to use and can be found in most pet stores, garden centers, or online.

It is important to note that catnip is not the only plant that can repel mice. Peppermint and lavender are also effective in repelling mice and can be used in combination with catnip for even greater effectiveness.

By using catnip and other natural methods to repel mice, you can avoid the use of harmful chemicals and keep your home free of unwanted pests. So why not give it a try? Your furry friends will love it and your home will be mouse-free in no time!
