Understanding Voles

Voles, also known as field mice, are tiny rodents that can cause big problems for gardeners and homeowners alike! Although they may appear similar to mice at first glance, voles have unique traits that set them apart, like their shorter tails, stockier bodies, and small eyes and ears.

Behavior and Habits of Voles

Voles are prolific breeders and rapidly multiply in favorable conditions, leading to massive population explosions. Some female voles can even give birth to eleven young at once; however, they typically have around four to six in a litter.

As herbivores, they have a penchant for munching on grasses, roots, bulbs, and tubers. Their distinctive tunneling creates intricate burrows beneath your feet, providing spiraling pathways leading to their shelters and food sources. 

Damage Caused by Vole Infestations

Vole damage is not just a nuisance; it can also hit you where it hurts— your wallet. These relentless rodents love nibbling on plant roots, stems, and bark, causing stunted growth, wilting, or even death. 

And it doesn’t stop there. Their constant tunneling can harm the soil’s structure, leading to erosion and putting lawns and gardens at risk. In agriculture, voles spell trouble, especially in winter when food options are slim. Their munching habits can reduce crop yields, dealing a hefty blow to farmers’ bottom lines.

Castor Oil

Castor oil traces its roots back to the seeds of the castor plant, scientifically known as Ricinus communis. Native to the tropical regions of Africa and India, this remarkable plant has thrived for centuries, with archaeological evidence suggesting its use dating back to 4000 BC! 

Castor oil is well-known for its natural benefits, especially in hair care. It can nourish and strengthen hair, tackling problems like dandruff and dry scalp. Applying it directly to your scalp or blending it with other oils can help deeply condition and encourage healthy hair growth. 


Plus, castor oil can help hydrate dry skin and soothe irritation. It’s often used to soften rough patches, reduce redness, and lessen inflammation. 

How to Repel Voles with Castor Oil

Here are some different ways to use castor oil to keep voles away! 

Direct Application

One of the easiest ways to repel voles with castor oil is by directly applying it to vole-infested areas. 

Identify vole hotspots like garden beds, lawns, or along the perimeter of your property. Pour or spray castor oil directly onto the soil surface, thoroughly covering the affected area. Focus on entry points, vole tunnels, and areas with visible signs of vole activity to send them packing. 

Homemade Repellent Sprays

Create your own vole-repellent spray by mixing castor oil with water and a small amount of dish soap. The dish soap will emulsify the oil and water, helping you distribute the repellent evenly. 


In a spray bottle, mix one part castor oil with ten parts water and add a few drops of dish soap. Shake the mixture well to combine, and spray it onto vole-infested areas, covering the soil surface thoroughly.

Commercial Castor Oil Products

Alternatively, you can opt for commercially available castor oil-based vole-repellent products. You can choose from ready-to-use sprays, concentrates, or granules to fight back against a vole infestation. 

To get the best results, make sure to follow the labeled instructions. Never use more than what the manufacturer recommends, and always apply these products properly and safely. 

Reapplication and Persistence

Remember that castor oil repellents may require periodic reapplication, especially after heavy rainfall. Monitor vole activity regularly and reapply the repellent as needed to maintain its effectiveness.


Remember that consistency is critical when trying to repel voles with castor oil, so be persistent and patient!

Safety Considerations

Although castor oil is typically safe for humans and pets, it’s important to prioritize safety while you use it. Avoid contact with your eyes, skin, and nose, and be sure to wash your hands thoroughly after applying it.

To prevent accidental ingestion or exposure, store castor oil and any homemade repellent solutions out of reach of children and pets.

Why Does Castor Oil Work?

You can easily repel voles with castor oil, but how? Let’s explore why castor oil stands out as such a powerful vole repellent:

  • Strong Odor: Castor oil has a potent and long-lasting smell that voles find repulsive. The strong scent of castor oil masks the natural odors that attract voles, making treated areas less appealing for them.
  • Unpleasant Taste: Besides its strong smell, castor oil also gives the soil a bad taste. Voles like to nibble on different plants and roots, but when they encounter soil treated with castor oil, they’ll quickly look for other areas to graze.
