Another myth that has been debunked...
5. Peeing From Your Stand Will Scare Deer Off: The old wives’ tale has it that if you do not bring along a pee bottle to your stand and answer nature’s call on the ground below, you may as well head for the house and find a new spot to. Research has shown, however, that the smell of human urine does not noticeably affect deer, if it affects them at all. One research project with penned deer had the researchers spraying all sorts of things into scrapes to see which deer liked best. In one case they used four things—buck urine, doe-in-estrous urine, human urine and car air freshener. Results? With bucks, doe-in-estrous was the most popular, followed by human urine, then car air freshener, then buck urine.
Stay as scent free as possible, and don’t turn the ground near your stand into a public urinal, but if you have to go, just go, and keep hunting.
