The Buck Bomb Rut Kit includes both the 2oz Doe 'N Estrus as well as the 2oz BucRut scent, a classic and effective combination for use during the rut. Doe 'N Estrus is urine drawn from an estrus whitetail doe, while BucRut is urine collected from a whitetail buck at least 3.5 years of age. Use with the included 4 spike wicks near your treestand, in front of trail cameras and/or over mock scrapes to attract bucks and force them to claim their area. Buck Bomb XTRUS is unlike any other deer urine that's ever been available - XTRUS is certified to contain levels of estrogen found in whitetail does. Each batch is lab-tested and certified for maximum estrogen levels before ever going into a "bomb" can. XTRUS uses a new, patent-pending deer urine collection method that provides fresh, peak estrus urine.
