Several years ago I had a mole/vole problem in my decorative plant garden and lawn. I use a pine, walnut shell, or other natural cat litter for my cats. These products often have instructions right on the bag to use them once used on inedible plant beds as mulch. So I poured the used litter from my several cat boxes into the mole/vole holes and voila! The little critters disappeared! It's been a long time and they haven't returned, but if they do, I'll surely put the kitty litter in the holes again. Any odor from the used litter disappears, especially after a rain.
Although moles don't eat plants, they can damage the roots of plants and lead to their decay by digging numerous canals in the ground. There are many natural ways you can drive moles out of your garden. These are some of them.
