LOL...I have to agree with Oldtimr.
But......If there is no fir or juniper where he's hunting it definitely would throw up a flag for any deer. And secondly, even in a fir or juniper grove the smell isn't that strong unless there are fresh cuts.
Man has been killing deer for years without any scent control and watching the wind. I use the detergent, bath soaps and shampoos, and spray down before I go out too. But I also am watchful of the wind direction. (Some things you just can't make neutral like your breath.) I am totally convinced that the best scent is no scent at all.
I've had them work for me on occasion but I am very cautious even using any of the various deer scents.
Want to have some fun with your hubby? Go buy a container of Evercalm (it looks like deodorant) and present it to him. Then he'll smell like a herd of deer....!!!
