only if you pee on a used tampon will it work......then the buck thinks theres a female human in heat and a mature male human after here. works best if you wring out the tampon into the scrape...then pee a little of your own in it. thats the best way. i like to sit at home and wring out used tampons and bottle the liquids just for this purpose...i do it all year and save it in a 55 gallon drum...
