Moles are a common problem in the typical homeowner's lawn. Mole tunneling can leave unsightly dirt mounds as well as areas where your yard will cave in. Removing moles isn't that difficult of a task. Moles love to eat grubs, so removing their source of a food is a great way to get them to leave your yard. There are also several other options to remove moles, although they not be as effective as removing the food source.
Purchase a lawn grub killer with and active ingredient of Trichlorfon. The grub killer will typically come in the form of granules. Apply over the entire lawn according to the recommended application rate on the packaging. Not only will this remove the grubs and help eradicate the mole problem, but it may also increase the health of your lawn since grubs love to eat grass roots.
Identify the active mole hills. You will see fresh mounds of dirt with a hole in the center. Pour used cat litter down the mole hill. Cats are a natural enemy of moles, so the moles may move to a different area if they catch the scent of a cat.
Water the area thoroughly where the mole problem exists. Water until the soil is moist. Spray castor oil over the entire area using a pump-up sprayer. Water the solution into the soil. The castor oil will upset the moles' digestive systems and may prompt them to move.
Plant chocolate lilies around your property. The bulbs of the chocolate lily emit a terrible odor which moles despise. A few bulbs on each side of your yard or garden will be sufficient.
Build a "mole screen" around small areas like gardens and planting beds. Bury hardware cloth or aluminum sheeting 2 to 3 feet into the ground all the way around the area you want to protect. Keep the barrier elevated 6 inches above the ground level. This will keep moles from tunneling underneath or crawling over the barrier.
