At a pet store get activated carbon for aquariums and place 1/2cup in a clean thin nylon sock or hose and tuck these into your boots after hunting for storage. Also keep them in the bag/box you keep you clothes in. It adsorbs the odors on you clothes like scent lok does from your body. Vanilla is great at attracting does and during the pre -rut you want to keep the does around for the boys!
