Answer: Woodchucks are difficult to deter from a garden. Although some gardeners have had success using repellent sprays, the most effective long term solution is a fence. It should be at least 4 feet tall, made of stout wire mesh, and buried about a foot deep with the buried part bent outwards (so the woodchucks will be foiled if they try to dig under the fence). If you leave another foot or two loose and floppy at the top it will discourage them from climbing over. Alternatively, the woodchucks can be trapped and removed. Any wild animal can be very unpredictable when cornered or trapped, so I suggest that you contact your game warden to find a professional to trap and relocate the animals.
