Formula is recommended for wiping on both sides of three to four scent sponges. Hang sponges by scrapes, rubs and high-traffic areas during the peak of rut. When done hunting for the day, put scent sponges in a 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, Elk. Type: Baits & Lures.
