Don't know of it spooks them or not...but I do not want to go through the hassle of a serious scent contold program to piss on the grown and have a deer avoid me. Ever smell urine when your dehydrated...it stinks to high heaven.After reading on here a few months back about how it does not mess with deer I whizzed out of my tree 2 times thisyear. It was cold and sitting watching the steam rise just made me keep thinking, man that smell is all around. Now whether itdoes or does not spook deer...I will not do it again for my own piece of mind.
