It's been my experience that non familiar scents will SOMETIMES put Moose on alert and sometimes even spook them but not generally. It's the familiar predatory scents that will spook them out of the area. Moose, unlike deer, aren't overly concerned given they are so big. Especially Bull Moose. Cows are much more wary. I've had more Moose in knife range than I care to think about and I know for a fact they scented me. They just didn't care. Now, having said all that, all the Moose in my experiences are pretty much animals with absolutely NO human contact experience in deep Alaska. I don't know where you are going to be hunting but if you are going to be hunting in an area where they have associated human caused scents, such as chemical as well as human scent itself, with danger then your experience will vary from mine.
