You guys will laugh but I have an Ozone machine that stays in my hunting closet and it kills the rubber scent. Bought one of the huge boundary waters water-proof duffel bags from Cabelas and it smelled like fresh rubber so bad it about gagged me - half hour in the "ozone room" and it was gone. Closet is lined with cedar but doesn't smell like cedar at all anymore after running the ozone machine. Scoff all you want but they work - I dont' have one to take to the tree but think it would help as well.
