What a coincidence, I've just set two scissor traps in my garden. I've caught 5 over the last 7 years and am quite a dab hand at it now. Very satisfying when you get them and I normally catch them in the first 12 hours of setting them. Make sure you get all the loose soil from the tunnel, cover your hands in soil to get rid of your human smell and make sure no light gets into the hole.
