Problem: Moles that destroy the garden by digging extensive tunnel networks.
Solution 1: To use human hair as an effective deterrent for moles, place small clusters in the moles' holes.
Solution 2: Like rabbits, moles will avoid garlic cloves, mothballs or commercial repellents. Placing any one of these items (or a combination of several) in the garden will generally take care of a mole problem.

To get human hair go to a nearby hair salon.
I have to be honest with ya though. While I'm a huge fan of trying to "save" the "poor critters"....four little words mean a lot right now....
