Answer: Moles create characteristic mounds and tunnels that rise above the soil level; voles have trails through tall grass, but have been known to use mole tunnels to feed on roots and bulbs. Moles are easily repelled with castor oil based products (such as Gardens Alive's Mole Med - call them at 812/537-8650 or e-mail email@example.com for more info). Voles may find fox urine a scary enough reason to stay out of your garden (see the Burpee catalog for this product). Hope this helps!
