We use unscented tampons or Hyper Wicks soaked in fresh deer urine as an attractant on our hunts. After the evening hunt wedrop the wick onto the ground under the low hanging branch ( tampons and Hyper Wicks are biodegradeable) and make a mock scrape with the urine soaked wick. If there is a buck in the area you will know within 48 hours, he will tear the ground up! We use Southern Whitetail Scent's Hyper Heat ( freshly collected doe estrous) and Hyper Rage (freshly collected buck urine)
We have harvested some really nice bucks in the last 2 years doing this.
