Most of the breeding takes place at night because we have spent weeks stomping around the woods during light making the deer do almost everything at night only briefly allowing opportunites at dawn or dusk during the night to day or day to night transition. Curiousity scents do work but anything made of an artificial perfume such as car deodorants will 98 out of 100 times (not a scientific fact or quoted ratio) alarm the deer and put them on alert when they encounter the smell. So the theory that perfume or artificial air fresheners will work as well as a natural pheremone sex attractant during the rut (which it is designed specifically for) is highly unlikely in my opinion.
