First off it should be noted that you cannot completely eliminate human odor, you can only minimize it.
1. Don't eat spicy foods because it will ooze out through the pores of your skin .
2. Wash with a non-scented soap like Ivory or one of the many scent control shampoo's available.
3. Brush your teeth with baking soda. If there are apple trees in your deer hunting area, eat apples as they are natures breath freshener.
Suck on a piece of apple when hunting.
4. Keep hunting clothing clean and odor free by washing it in baking soda or Sport Wash. DO NOT wash your camo clothing in any of the supermarket detergents that have ultraviolet brightners. Deer will see your cloths glowing in the UV segment of the colour spectrum.
5. Store your hunting clothes in a tote with some pine, spruce or cedar branches.
6. A great cover scent is fox urine. This works very well . The fox pose no threat to deer and the urine is an odor that deer encounter all the time .
7. Racoon urine also works very well.
8. PLAY THE WIND.
