Tired of moles and voles wreaking havoc on your beautifully manicured lawn? Before you resort to traps or poisons, consider an eco-friendly alternative—Homemade Castor Oil Mole Repellent Recipe. This all-natural recipe offers a humane way to deter these yard invaders without causing harm.

Why Opt for a Natural Homemade Mole Repellent?

Ethical Considerations

Many homeowners are uneasy about using traps or poison baits to eliminate moles and voles. Not only do these methods lead to the animals’ death, but they also pose risks to other wildlife and household pets. A homemade castor oil mole repellent offers a kinder alternative.

The Castor Oil Advantage

Castor oil contains ricinoleic acid, a unique fatty acid that’s beneficial for human skin, hair, and overall health. Interestingly, this same component serves as a potent deterrent for voles and moles.

Efficacy of Castor Oil as Mole Repellent

If you are wondering about the efficacy of Castor Oil as mole repellent, here’s how it works:

1. Sensory Disruption

Castor oil is rich in ricinoleic acid, which is responsible for its unique smell and taste. When applied to the soil, the castor oil permeates the ground, radically altering the sensory landscape that moles and voles are accustomed to.

This ingredient targets these animals’ olfactory and gustatory senses, making their familiar environment suddenly foreign and undesirable. In simple terms, their habitat’s new scent and taste make it unappealing, encouraging them to seek new grounds.

2. Impact on Food Sources

It’s not just the soil that gets impacted by castor oil; the solution can also affect the taste of insects, earthworms, and other invertebrates that make up the primary diet of voles and moles.

When these animals find that their food sources have an altered taste, it serves as an additional push to abandon their current residence in search of more palatable feeding grounds.

3. Combined Effects

The effectiveness of castor oil as a vole and mole repellent is not just due to a single factor but a combination of sensory disruption and food source alteration.

The dual-action nature of castor oil for voles and moles ensures that these creatures are not just repelled on one front, but find their entire living conditions upended, making your yard a less attractive place to stay.

DIY Castor Oil Mole Repellent Recipe


  • ¾ cup of castor oil
  • 2 tablespoons of eco-friendly/biodegradable dish detergent
  • 1 gallon of tap water
  • Spray bottle or hose sprayer


  • Mix the first three ingredients in a blender to ensure thorough mixing, as castor oil and water do not mix easily.
  • Pour the mixture into a spray bottle or hose sprayer.
  • Dampen your lawn using a garden hose or sprinklers.
  • Focus on spraying the entrances to existing tunnels.
  • Proceed to spray the rest of the yard.

Maintenance and Frequency

Reapply your DIY mole killer weekly until you notice the animals have moved away. Being consistent with your applications will ensure that you get rid of voles with castor oil effectively.

Warnings and Precautions

  • Alternate Habitats: Before using the castor oil mole repellent recipe, ensure that the animals have an alternate place to move to. Failure to do so could result in them digging new tunnels elsewhere in your yard.
  • Urban Challenges: For those living in urban environments with limited green space, driving moles and voles to new habitats can be more challenging. Hence, a full-yard spray is recommended.
  • Weather Conditions: Apply the vole repellent homemade solution after every rainfall to ensure its effectiveness. The rain can wash away the repellent, necessitating reapplication.

Key Takeaways

Homemade castor oil vole and mole repellent offers an ethical and effective way to manage these yard pests. This DIY mole killer is not just simple to prepare but also kinder to the environment and the animals it targets. With regular application, you can say goodbye to moles and voles, and hello to a pristine lawn.
