The strongest and most natural cover scent you'll need is in Herd in a Bottle concentrated liquid. A 2-oz. bottle should be enough for a season of bowhunting. Formula is recommended for applying on both sides of three to four scent sponges. Hang sponges by scrapes, rubs and high-traffic areas during the peak of rut. It may also be used with Scent Trax for a dragline. When done hunting for the day, put scent sponges in zip-loc bag to store. When returning to hunt, wipe fresh scent on the sponges. Leftover product should be vacuum-sealed to preserve freshness at the end of the year. Available: Whitetail. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Baits & Lures.
