I have a friend that has moles, voles and all kinds of stuff. Lives in the country on 3 acres. The hawks get the voles.

He keeps the moles out of his front yard and flower beds with castor oil. He puts the pellets in his flower beds and sprays liquid on the front lawn. It really works. He let's them have the back yard.

Here's the pellets at Lowes. https://www.lowes.com/pd/EPIC-Mole-Scram-10-lb-Bag/5000151281

I am going to use these this year. For those who don't like to use chemicals, Castor Oil is the main ingredient. Not harmful to other things, repels moles.
