Bleach. One bottle of bleach kept them off my friend's farm for a month and a half! He had the same problem. At the same time, put an Ultimate Scrape dripper above him, then when he gets in the stand, he'll have doe pee all over him. Better yet, fill it with Active Scrape, this includes both genders' urine and secretions (fecal matter ). Put some Vaseline on the ladder to about five foot high, so if he happens to make it farther he doesn't kill himself. Last but not least, after all of the above, my friend's piece of advice: when you find someone else's stand (or in your case, your stand being used by someone else) around where you hunt, climb up there after liberally applying cologne, and crap on the platform AND seat of the stand. Good luck!
