This is a bad year for both Voles and Pocket Gophers....I don't think we have actual Moles here. For the pocket gophers there is a trap that you can get at UFA. It's a black box with the bottom and one end removed. The other end has a hole. When the gophers goes into it to cover the hole (they hate daylight) they get caught and killed in the trap. You may see a lot of those nice dirt mounds, but you don't have as many critters as you have mounds. You have to be selective about which mound you set up on. Go for the freshest dirt. I'd start with 6 traps and mark the locations with landscape markers (wires with fluorescent tape). For voles which dig those neat little trenches, the solution is mouse traps. But I wouldn't worry about them, they'll die off and go away. This past winter, I've been told is responsible for this problem. Believe me, you're not alone.
