rambler, sorry to hear about your mole problem. the "little gentleman in velvet" is a serious pain in the ass if you appreciate a nice garden.
I've had them in the past. I got got rid of them ( ok, killed them) using tunnel traps. these are much easier to set than scissor traps and a damn sight more efficient when it comes to putting mole out of ones misery. I drowned one once, using a power washer, but you'd have to be there all day to win the war like that. tunnel traps are the weapon of choice.
