Attract bucks by pretending a female deer in heat is in your hunting area with Proxpedition's Mature Female Synthetic Urine. This urine is created in our laboratory from the analysis of 100% natural urine from a rutting female deer. Perfectly mimics an ovulating female deer wandering the territory. Simply spray pads or pour Doe in Heat Synthetic Urine into the scrapes. For best results, apply Heat-60 to one boot and Rut-60 to the other while walking in the woods to simulate a male following a female.
