For areas where natural urine scents are not allowed, The Buck Bomb Synthetic BucRut Bomb contains 6.65 ounces of synthetic scent that imitates urine from bucks at least 3½ years of age. It’s the most efficient and effective way to trigger dominant behavior in mature bucks from the pre-rut through the peak of the breeding period. Use Buck Bomb Synthetic BucRut while in your stand or blind, or when stalking deer to create a barrier of cover scent between you and the animal.
