The Buck Fever Forehead Gland Scent is designed to simulate fresh forehead gland activity by marking overhead branches and rubs as well as trails and vegetation adjacent to stand sights before season and continuing all season long. The BF Gland is a synthetic forehead lure that imitates the scent a buck deposits on licking branches above scrapes and on buck rubs. When dry, BF Gland crystallizes and is still present so when moistened again from rain or dew, the scent reactivates for continuous work.
