Hi, If you have moles, you'll see raised ridge-like tunnels across the surface of your lawn. They feed on earthworms and don't harm your garden, but some people hate the ridges. The Liquid Fence company carries some mole repellent products. You can buy it at most garden centers. However, keep in mind that moles move on to other areas, especially as the summer warms up so they are often a temporary situation.
