For areas where natural urines are not allowed, Buck Bomb BucRut imitates fresh urine collected from bucks that are at least 3.5 years old. As the same scent that is found in the Synthetic BucRut Bomb, BucRut will boost the drawing power of your mock scrapes, particularly during the pre-rut and peak rut period when bucks are most aggressive and territorial. BucRut urine is the most efficient and effective way to trigger dominant behavior in mature bucks from the pre-rut through the peak of the breeding period.
