Safer Brand Deer Off Weatherproof Deer Repelling Stations work to protect your yard from deer destruction. The smell mimics that of a dead or decaying animal, which triggers the deers flight response and trains them to stay away. The intense scent deterrent is easily detectable by the heightened senses of deer, but is odorless to humans. The stations are ready to use and come with 6 stations and 6 stakes to conveniently stake your repellent into the ground. You can also hang stations from fencing or low-lying shrub or place them in a flowerpot or flowerbed. For best results, places stations no higher than 2 feet above ground level and no more than 4-6 feet apart. One 6 pack covers up to 192 sq ft for up to 90 days.
