I enclosed an area with this product (PLOT SAVER) a few weeks back & since that time we sprayed the ribbon two times in a five week period. The direction said, it would keep deer away for 3 to 4 weeks. When I went to ckeck on the new clover field just before dusk there were seven deer inside the plot.Upon inspection, the deer are eating the clover as mush as on the outside of this area.

Would I buy this product again. No.
