While you can bolster your chances of hunting success by hiding your own odor, you can also attract deer by using odors that they like. Many attractant scents are made from urine, whether buck urine, doe urine or doe-in-heat urine. Buck tarsal gland scents are also available, as are preorbital and forehead gland scents, often used at buck rubs, scrapes or mock scrapes. Other attractant scents might smell like a food deer love, like apple or acorn scent. The most commonly used scent is doe-in-heat scent, which is fairly effective all year except for very early in the season before any does come into heat. When used in conjunction with a doe decoy, it can also be effective at bringing a big buck into bow range during the heat of the rut.
