Answer: There are many "home rememedies" and repellent products you can try to deter both of these pests, and you can certainly try them. In some cases, the only guaranteed solution is a physical barrier. Deer require at least an seven foot fence, groundhogs need a heavy duty wire mesh both above and below ground. Deer are creatures of habit and will develop a pattern or habit of movement, using the same path for an approach direction and a second path for a departing direction. They'll repeatedly follow a familiar path until they sense or encounter some form of harm or danger there. I've discovered that a length of heavy strength monofilament fishing line, stretched across the approach path 24 to 30 inches above ground level and tied at either end to a half-inch willowly tree branch will stop an approaching deer. It appears that deer are confused by the unknown or unseen resistance and will change direction to avoid a questionable situation. Also, I've discovered that light-weight, noise-causing objects attached near the ends of the stretched lines will spook a deer away from the immediate area when they encounter the monofilament line. By studying the movements and changing the location of the stretched line each time they attempt a different approach, you can cause deer to avoid the area of doubtful encounters. I hope this information is helpful!
