In reply to Reach>Talent:
Traps, the only way.
I hate killing but the only good mole is a dead mole.
Buy the pincer type traps not the half tube with lots of wires type.
Set the trap so it doesn't take much to set it off.
Put in the run, probe around a fresh mole hill with a tent peg.
Dig space for trap and clear entrance to passages.
Back fill with soil, not letting very much drop into the hole.
Crucially make it light tight. I put a pot plant pot or bucket over the top.
