Homemade Ground Mole Repellent With Dawn Dish Soap and Castor Oil

2 Materials
10 Minutes

If you’ve been working hard on your lawn and garden, one of the most frustrating things you can find on your grass are mole hills.

Those large lumps of brown dirt can totally ruin the look of your luscious lawn, and burrowing rodents can cause damage to the grass roots underneath.

You can get live traps and relocate the moles but I have a recipe to share that uses one of my favorite household supplies: Dawn dish soap. Combined with castor oil it makes a great natural mole repellent for your lawn. Many commercial repellents use concentrated pellets or liquids composed of castor oil and other irritating ingredients to drive moles away. Now you can make your own!

Ingredients for Homemade Mole Repellent

  • 2 Tbsp Dawn Dish Soap
  • 6 oz Castor Oil
  • 12 cups of Water
  • Large jar with tight fitting lid
  • Spray bottle attachment for hose

Moles hate castor oil. When you apply it to the soil, it acts as a natural repellent. The castor oil doesn’t kill the moles but it will upset their digestive tract and cause stomach upset. If it get on their skin, it will make them itch. The castor oil won’t cause permanent damage but it will make them reroute their tunnels elsewhere.

  1. Heat water in kettle
  2. Pour castor oil into jar
  3. Pour 3 quarts of hot water into the jar
  4. Add Dawn Dish Soap
  5. Shake or stir the mixture together
  6. Pour the mixture into a garden sprayer
  7. Spray lawn
  8. Pour extra directly onto mole holes

Repeat application in one week if moles are not completely gone.

For best results use in early spring before mole breeding season starts.
