How do I spray castor oil in my yard?

Spraying castor oil in your yard can be an effective way to repel pests such as moles, voles, and gophers. Here is a step-by-step guide on how to do it:

1. Gather the necessary ingredients and equipment: You will need 2 fluid ounces of Castor oil, 3 tablespoons of liquid detergent, 8 tablespoons of water, a blender, and an Ortho Dial n’ Spray.

2. Measure and combine the ingredients: Start by measuring 2 fluid ounces of Castor oil and 3 tablespoons of liquid detergent. Pour them into the blender. The Castor oil acts as a natural repellent, while the detergent helps to emulsify the oil and create a frothy mixture.

3. Blend until frothy: Turn on the blender and blend the Castor oil and detergent mixture until it becomes frothy. This usually takes a few seconds. The frothiness helps to distribute the solution evenly when sprayed on the lawn.

4. Add water and blend again: Once the Castor oil and detergent are frothy, add 8 tablespoons of water to the blender. Blend the mixture again to incorporate the water. This step helps to dilute the solution and make it easier to spray.

5. Fill the Ortho Dial n’ Spray: Pour the castor oil solution from the blender into the reservoir of an Ortho Dial n’ Spray. This type of sprayer allows you to easily adjust the spray pattern and coverage.

6. Set the spray rate: Depending on the specific model of the Ortho Dial n’ Spray, you may need to set the spray rate. Follow the instructions provided with the sprayer to determine the appropriate setting. This will ensure that the castor oil solution is applied evenly across your lawn.

7. Begin spraying: Once the sprayer is filled and set, it’s time to start spraying your yard. Begin at one corner of the lawn and work your way across, overlapping each pass slightly to ensure thorough coverage. Pay special attention to areas where you’ve noticed pest activity or where you suspect they may be entering your yard.

8. Reapply as needed: The effectiveness of the castor oil solution may diminish over time, especially after rain or heavy watering. Monitor your yard for signs of pest activity and reapply the solution as needed. It’s generally recommended to reapply every 2-4 weeks or after significant rainfall.

By following these steps, you can effectively spray castor oil in your yard to repel pests. Remember to always follow the instructions provided with the products you use and take necessary precautions, such as wearing gloves and protective clothing, when handling and applying the solution.
