I bought it last year to use early season instead of the spray. Let me just warn you. IT MADE MY SCALP ITCH LIKE I HAD LICE!! I patted it on my hair one time because I had sweated a bunch getting to my stand. Never again. I still use it to pat down on my pants, my pits and boots when it's hot. Don't have any idea if it works or not. No way to tell.
