Trapping works but you have to do some work to set the traps properly. I have used the Victor scissor traps and they kill moles. The trick is that you have to find a tunnel they use for travel as opposed to just an offshoot where they push the dirt up to the surface. The traps have to be set carefully so they are positioned in a way that the mole is forced go through them when they traverse the tunnel. Also, it helps to use rubber gloves to keep human scent off the traps.
