davidmil is 100% correct......but DDW does work, and IMHO, it works much better than ScentKiller or HS Scent Away. Not that those don't work, they do. I used them for several years and after a recommendation I used DDW exclusively this year. I noticed a difference almost immediately.

DDW is good stuff, and it works, but so do the others. If ya wanna use Scent Killer or whatever, hey, by all means. Something is better than nothing.
