Make your own mole repellent! 1/4 cup castor oil, 6 tablespoons water, 2 tablespoons liquid detergent (We use Dawn). Combine all ingredients in blender until consistency of whipped cream. Add 2 tablespoons of repellent to a regular garden watering can and then fill with warm water. Thoroughly water over areas of greatest damage.
