Buck Bomb Doe 'N Estrus contains 100% urine that is collected from does during the peak of the estrus cycle. As the same estrus that is used in Buck Bomb aerosols, Doe 'N Estrus urine will boost the drawing power of your mock scrapes particularly during the peak of the rut. The easy-to-use dropper bottle contains four ounces of premium, potent Doe 'N Estrus liquid urine attractant that is perfect for use with the Buck Bomb Detonator retractable scent wick (sold separately) or the included spike wicks.
