Whether you want to get rid of moles in your yard because they are creating raised, crumbly "runways" all over your lawn or you are concerned with protecting your garden, you have a wide variety of options. Whether you opt to trap the moles, kill them or just drive them away naturally with unpleasant smells and materials, you can implement a variety of options to make sure your moles are really gone.
Identify the main runways. These typically are runways that extend in a straight line. If you stomp on a runway with your foot and it is a main runway, the moles will repair it within a day.
Flood the runways. Follow the main runway to its entrance, then use a garden hose to fill the runways with water. This will not drown the moles but it will force them out of their tunnels and destroy the system. Once you have flooded the runways, monitor them for repairs. If they are not restored within a few days, then you have likely gotten rid of your moles.
Sprinkle your lawn with cat litter and coffee grounds. Coffee grounds smell unpleasant to moles, and cat litter makes moles think that their natural predators, cats, are in the area. This can cause them to move out and move on.
Place mole traps in the tunnels if the natural methods do not work for you. In most cases, you will dig into the main runway to place a trap. Pit traps catch the moles alive so you can release them, while other traps kill the moles. Follow manufacturer directions for placing and setting traps, since every manufacturer's traps are slightly different from others'.
