Moles can destroy your lawn.
This can be extremely frustrating, especially if you take the time and spend the money to groom your lawn into a beautiful piece of art. Lawns can cost thousands of dollars to repair or install and with moles digging 10-20 feet of tunneling a night the damage can happen fast. Moles are territorial, so to have 2-3 moles per acre is considered a heavy infestation. Contrary to popular belief, moles primarily feed on earth worms, not grubs. Grubs will only make up about 5% of their diet while worms make up the rest. The tunnels that you see uprising and destroying your lawn or mulch beds are the feeder tunnels. Moles make those to hunt down food. Moles create deeper subterranean tunnels in which they live in and raise young. Moles will abandon a feeder tunnel as fast as they make them if they don’t think its a good catch for food. On the bright side, having moles is almost a good sign. They are there because your lawn has a food source they love, the worms. Worms are good for lawns since they help to aerate, fertilize and turn the soil over. Although, the moles don’t help with their feeding habits.
