Have run across a few tips this past hunting season, thought i would post em and open it up for more input.
film canisters with cotton balls, scent
tampon used as a drag with fox urine or whatever
cover scent posted in Oct. distilled h20, hydrogen peroxide and baking soda (have a jug brewing not used/tried it yet)
1/3 pinesol with 2/3 water, spray bottle
boiling cedar boughs/pine, leaves etc from the area you hunt
add to spray bottle
