I have a vegetable garden and I encourage earthworms. So, I encourage the moles. It's very frustrating. There are a lot of really good gopher traps on the market now. I've caught some moles in them. Mole holes aren't as durable as a gopher hole so it's harder to set the traps. I think there is promise for the one called Gopher Hawk.
Very frustrating.
Good luck.
