Apparently, moles absolutely hate noise. I have read about a method in a gardening magazine here that apparently works. Knock some metal/iron rods about 8 inches deep into the ground in the area where the moles are wreaking their havoc. Hit something regularly against these so that quite a loud sound is produced which spreads underground. One must, however, do this quite frequently, so it works.
Sounds daft, I know, but may be worth a try.
