Buck Bomb BucRut contains pure, fresh urine collected from bucks that are at least 3.5 years old. BucRut will boost the drawing power of 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.
