One of the greatest temptations that lures moles into a lawn is the presence of Japanese Beetle Grubs which is a perfect source of food.  Eliminating this food source will reduce the temptation for moles.  More on grub control HERE..Milky Spore is the control I’d suggest.  Having said that, eliminating grubs won’t actually get rid of moles that have already set up their territory in your yard since they also eat earthworms.  To drive the moles out of the area, you’ll need to apply Mole-Repellent to the lawn once a year…more on that HERE.
