Anyone have any ideas for mole repellants? Have tried mole (castor) beans and castor oil mixes sprayed on the ground. Sonic devices seem to work a little. But nothing seems to work as a deterrent. I know there are lethal ways to attack the vermin but even that works with limited success.

They are a protected species in the area and poisons are not supposed to be used. But the foot holds and sink holes are a bit much to live with in a lawn. I would prefer to find something natural if possible that would keep them away. I really prefer not to kill anything that can be avoided. They are just a creature trying to survive like the rest of us. Would rather they do it somewhere else is all.
