The tender seedlings that appear shortly after germination are extremely tempting to a browsing whitetail and some can actually be killed by browsing at this stage. Fortunately, Plot Protector lives up to its name. Each kit allows you to protect one acre for 90 days with a powerful wall of scent that repels whitetails. Once the crops have established themselves in the planting area and are durable enough to survive and thrive on their own, remove the Plot Protector System and watch the whitetails follow their noses and stomachs to a nutritious, attractive food plot.
