Plants That Repel Rodents

Rodents like mice and rats may be cute in animated movies, but having them invade your home or garden is an entirely different story. These unwanted guests can wreak havoc on your property, chew through wires, and contaminate your food. While there are various methods to keep them at bay, such as traps and poisons, there’s another solution you can try: plants that repel rodents.

These are not just old wives’ tales; many gardeners and homeowners have successfully used these plants to deter rodents. Let’s dive into some of the most proven options.


Peppermint, cherished for its delightful flavor in tea and confectionaries, is also a powerful rodent repellent. The secret to its success lies in its refreshing scent, which rodents like mice and rats find highly offensive.

When strategically planted in your garden, peppermint enhances the garden’s visual appeal and creates a natural barrier against rodent intrusion. 

If planting isn’t an option, dried peppermint leaves in sachets near potential entry points can release a constant stream of aroma, discouraging unwanted visitors.


Lavender also serves as an effective rodent deterrent. Its scent is a powerful repellent for rodents, making your home and yard an unwelcome space for mice and rats. 

Plant it strategically as a border or interspersed among other plants to create a practical and visually appealing barrier against rodents. 


Daffodils serve a twofold purpose in your garden. While their bright and cheerful appearance may not immediately scream “rodent repellent,” they have a hidden talent that can help protect your outdoor space. 

These springtime favorites contain a compound called lycorine, which is toxic to rodents. When you thoughtfully plant daffodil bulbs, you introduce a splash of color and create a practical deterrent against unwanted garden guests, such as mice and rats. Just be sure to keep them out of reach of your pets and children, as lycorine can be potentially toxic.


Rosemary, a true multitasker in the garden, extends its capabilities beyond culinary uses. While it’s renowned for elevating flavors in your dishes, its robust and aromatic scent conceals an unexpected talent – it’s one of the remarkable plants that repel rodents, protecting your garden from damage.


Onions, a kitchen staple, have a dual role to play in your garden. Beyond their culinary contributions, they emerge as unexpected yet invaluable assets in rodent control. Their distinctive, pungent aroma is a well-established deterrent for rodents. 

Although not foolproof, rodents are inclined to avoid areas with onions, which can act as a protective barrier.


With their bright orange and yellow blooms, Marigolds rely on a powerful tool to ward off pests: their distinct scent. These flowers emit a strong fragrance that’s highly effective in repelling rodents and common garden insects like aphids and mosquitoes. 


Mint plants, like peppermint, have a potent odor that rodents dislike. Whether spearmint, catmint, or any other mint variety, their strong fragrance will make your garden unattractive to rodents. Be cautious, though, as mint can be invasive, so consider planting it in containers to control its spread.


Euphorbia, including the “mole plant” (Euphorbia lathyris), offers an intriguing way to keep rodents away from your garden. These plants that repel rodents are known for their milky sap, which contains toxic compounds to rodents. 

The Pros:

  • Natural Deterrent: Euphorbia is a natural and non-lethal way to keep rodents at bay. By simply having these plants in your garden, you make it unattractive to rodents, so they’ll go elsewhere for a meal.
  • Low Maintenance: Euphorbias are easy to take care of. They don’t need much water and can grow in various soil types. Once you plant them, they pretty much take care of themselves.
  • Aesthetic Appeal: Euphorbia plants come in different shapes and sizes, making them visually attractive in your garden. They can add a unique touch to your outdoor space.

The Potential for Harm:

However, it’s essential to be cautious when dealing with Euphorbia because the milky sap can be harmful to humans:

  • Skin Contact: Always wear gloves and long sleeves when handling Euphorbia to avoid skin irritation. If you get sap on your skin, wash it off with soap and water.
  • Eye Protection: Protect your eyes from contact with the sap, which can be irritating. If sap gets in your eyes, rinse them with water and seek medical help if irritation persists.
  • Ingestion: While the bitter taste of the sap usually discourages humans from eating it, keep Euphorbia out of reach of children and pets to prevent accidental ingestion.


Alliums include plants like garlic, leeks, and chives. These savory members of the onion family can deter rodents with their strong odor. Planting alliums in your garden can serve a dual purpose – repelling rodents and providing fresh, flavorful herbs.
