Thank you very much for your inquiry. Moles are a problem all over the US. There are many products out there that promise some level of control, most of which have some level of truth with results hard to verify or duplicate. The only method I am comfortable with recommending at this time that I know works is mechanical trapping. There are several types of traps, my favorite for most moles is the harpoon trap. You can buy these at any hardware store. The big issue with using this harpoon trap is getting is set and then checking the trap often (1-2 times per day). This exercise should be treated as you would fishing, in that you need to check the lines often. When you set the trap, it must be in an active tunnel.

Now, a couple of things about moles. First, there are not as many in your lawn as you think, trust me. They are quite territorial. Second, if you begin this exercise, you will find that they make runs through their tunnels at almost the exact same time every day. Stomp down their tunnels and watch them push back up, you will get their pattern very soon.

Again, thanks for the question and let me know if you have more.

Respectfully
