There's nothing that can ruin your yard the way a mole can. No matter how hard you work on the grass, moles are lurking beneath, digging beneath that perfect turf and creating unsightly piles of bare dirt. It's a frustrating problem, but can you do anything about it? The answer is yes. With some persistence and patience, you can start to get the upper hand on these subterranean pests. Here are four strategies.
Eliminating Food Sources
Most wildlife enters an area because there is food there. If you can eliminate the food, you can indirectly eliminate the pest. Because moles eat a lot of turf grubs, you can apply a grub control product to reduce their population and encourage the moles to dine elsewhere. An added bonus will be improved health for your turf and fewer beetles and moths around your landscape. Keep in mind that future applications will be necessary because the moles may return just as soon as the grubs do.
Trapping Systems
Moles are active animals, constantly on the move in the network of tunnels they have built. There are several types of traps on the market that are designed to take advantage of that movement. You simply insert them into an active tunnel, and the trap quickly and humanely exterminates the moles. Be sure to remove the target and reset the trap as soon as possible to continue your progress. Bear in mind that they could still repopulate your yard from elsewhere, so be prepared to set the traps again later on.
Destroying Tunnels
With a heavy foot or a shovel, you can do considerable damage to the moles' tunnel system. It's possible to cut them off from food or simply frustrate them so badly that they slowly migrate out of the area. Anytime you encounter their tunnels or mounds, push them firmly back into place to make it more difficult for them to return. You might consider flooding tunnels with water from a garden hose or simply opening the tunnel to allow sunlight and rain to enter.
Using Fumigants
This option is limited in its availability. There are products on the market that you can deploy in the tunnels much like the "bomb" insecticides used in homes. They can be very effective, but the limitations may make it impractical. First, not every state permits such products to be used. Make sure you don't buy a product in another state and then use it at home. Second, the tunnels can span a large area, so your fumigation may go into a neighbor's yard. Make sure they are agreeable to this.
Moles are destructive, messy pests. If you have an infestation, you don't have to just put up with it. You do have options for managing the situation in a way that will safely manage the mole population, preserving the beauty of the lawn you work so hard to create.
