Moles are a common garden pest that can cause a great deal of damage to your yard and garden by digging underground tunnels that kill plants by destroying their root networks. Fortunately, there are a number of things that you can do to prevent moles from taking up residence in your yard, helping to prevent such issues from manifesting themselves.

Aeration

If you don't already, you should have your yard and garden aerated, which is the process of punching multiple small holes in the soil. This will break up the concentration of roots within the dirt, creating empty spaces that are not attractive to worms and insects. Since moles are digging around in search of these insects to eat, reducing the amount of hospitable space for their prey will discourage them from staying in your yard.

Hardscaping

Installing hardscaping in your yard, such as in the form of a walkway or patio, can help break up the overall amount of space that moles could potentially move around in. Hardscaped surfaces also reduce the total amount of breeding ground for insects that moles prey on, which can reduce the likelihood that they will enter your garden in the first place.

Pest Control

As mentioned above, moles are primarily attracted to insects and grubs in your garden. This means that a good way to prevent them from entering is to eliminate those bugs entirely. Applying insecticide to your yard to kill off the population of insects and other pests can make it much less likely that you'll experience a mole problem, since they'll head elsewhere to find food.

Fencing

Another good way to physically block moles from entering into your garden is to bury fencing around the edges of your garden. Metal or wire mesh buried about a foot below ground should be enough to stop any moles who seek to take up residence in your garden. This will also act as a barrier against other pests which may try to gain entrance to your yard, such as rabbits and voles.

Traps

Finally, if all of the above steps haven't worked and your yard has developed a mole problem, the best way to get rid of them is to install traps in your yard. Mole traps can be found at most hardware stores, and come in either lethal or humane varieties. You should check the traps every day: lethal varieties will have to be emptied with gloves and safety gear, whereas humane traps can simply be opened, provided that you take them far enough away from your garden.
