i use baking soda on dust my crotch, behind the knees, and ankles of my boots and pant legs. I will dust myself with forest debris and leaves If I believe that any car odors are sticking to me. I don't doubt that the deer can smell human scent. However, at least around here, where I hunt, they are very used to smelling us humans, at all times of the year, and I find that dusting myself with woods ash from a recent fire, or with leaves and dirt helps to confuse them as to WHEN I was there, as well as where I am now. The baking soda neutralizes a lot of raw human scent.
our scent comes from dead skin cells( rafts) falling off the back of our necks, our face, hands, wrists, and ankles. If you wear rubber boots, you can tuck your cuffs into the boots and hold the skin rafts inside the boot. Dusting the outside of rubber boots, or even using an attractant scent, like Doe In Heat, works, provided you don't use a lot. Stick a drop or two on the instep of the sole of the boot. That is enough. Because of the strong presence of hormones, and other human scents at your crotch, using Baking Soda to neutralize this scent area works. Most deer have a scent zone they test with their noses that is barely more than 3 feet high off the ground. Even a large buck has a hard time raising his nose high enough to smell an odor that is 5 feet off the ground. 5 feet is only chest high on me. So, the armpits get some baking soda, rather than scented deodorant, and I wear either a hooded sweatshirt/jacket/ or a parka in cold weather to help keep the heat off the back of my neck and head from dropping skin rafts all around me, and from the neck down. I cold weather I do wear a ski mask, but in the early season, I don't. Skip the toothpaste with the mint flavor, the mouthwash with mint flavor, or any other thing you normally do in the morning. Don't smoke. Don't eat food with strong spices to them- even cinnamon rolls-- and I do love them--- become a " lunch " extra, but are foregone in the morning. Eat an apple, provided apples are commonly grown in the area where you hunt. ( HINT: if they aren't, plant some seeds, and grow some apple trees. In about 20 years, you will have one of the best deer " magnets" you can find in the woods.)
