Things You'll Need
Dawn (or another brand) dishwashing liquid
Bottle-style sprayer attachment for your garden hose
Many people do not realize they have a mole problem until someone walking in their yard steps in one of the mole's holes and twists an ankle. These burrowing rodents spend most of their lives underground and may have dug hundreds of feet of underground tunnels for each visible hole in your yard. A simple treatment that does not harm the moles will convince these meddlesome diggers that your yard is not the place for them.
Pour 4 ounces of castor oil and 1 tbsp. of dishwashing liquid into the bottle of your garden sprayer. Add water to fill the sprayer to the top and shake very well.
Coat your lawn with the mixture. Be sure to give it a thorough coating. For large lawns, a sectional approach may be necessary to adequately coat the lawn. Simply mix another bottle and go back to spraying.
Fill in the visible mole holes with dirt, soaking the dirt fill with the mixture.
Repeat Steps 1 to 3 after about a week, filling in any new holes. Most of your moles should be gone, but a second soaking will ensure that any remaining moles move out and don't return.
Repeat the application as needed if mole activity reappears. Spray the lawn at least once with the mixture early each spring to keep moles from moving into your yard.
