Imagine a deer fence with no wires, just posts. That's how unobtrusive this Wireless Deer Fence looks. The two-foot-high posts contain a strong chemical attractant, and they deliver a battery-powered electric shock when deer try to take a sniff. If deer get the message, they will avoid the area in the future. Three to six posts will protect 1/3 acre for a cost of $59.95 per year; 15-18 posts are needed for an acre.
