as has been said it is a variable thing. I know I have fooled a deers scent, or enough to have them not know what I was when down wind of me. Other times no. I take the precaution with clothing (though I don't spend the extra on scent control clothing). Wash it well in unscented soap or baking soda. Same for me, focusing on my crotch, arm pit, hair, behind my ears and along my nose, the areas that produce the strongest odors. I never get the opportunity to have a steady wind, so I do what I can to control scent and hope it is diluted and low enough to not cause complete panic in swirl.
