(... better a late answer than no answer?)
Moles aren't fun to get rid of. They are kind of cute. They eat bugs and worms, not plants, (but they can tear up a garden). The lethal methods make a mess. And the kinder methods just get whacky. There must be more urban legends on mole control than on any other pest.
The best poison uses a poisonous fake worm. Just the names alone, of the kill traps, are scary: harpoon, scissor-jaw, and choker loop.. . think about it, how repellent is a vibrator, juicy fruit gum, or pickle juice?
This is a great statement I found on the OSU Extension website
: "... mole damage could be reduced or eliminated by not encroaching on the mole natural habitat."
Kidding aside, I have never tried to get rid of moles. Gophers, yes. No guarantees, (this worked on a gopher once), but how about flooding your garden? If the mole doesn't pop out half-drowned, then the mud will make it hard for it to move around, and it might leave.
Unfortunately, tough to make this call for me, because I don't know your conditions. I like the suggestion on the OSU site to modify the garden habitat, by taking out the lawn, going natural, and living with the mole.
