I've never had any luck catching them.
My options are
1) If I see them I get my gun.
2) I buy these things called gopher gassers, available on amazon or my nearest country store. Using them requires finding all the holes (the hardest part) and they need to be home. They will almost always be home in the middle of a hot day. Then you fill in all the holes with rocks and dirt except 1. You get rocks and dirt ready for the last hole. Light it, throw it in fuse end first and fill in the hole with rocks and dirt quick as you can. These things have never failed for me. They may not be legal where you are.
