It takes 24 hours before all human scent it removed from an area. If you put on some rubber laytex gloves or neopreem gloves with a little scent eliminator or even animal pee or acorn scent you will leave no human oder behind that is strong enough to scare deer away. Deer only leave an area when there is a strong human oder. Deer are know to smell you from hundreds of yards away but it all depends on how much scent molecuels they are picking up. If they can smell a little bit of human oder than 9 times out of 10 they wont scram. Well good luck to ya! Shoot the MONSTER!
