I would say that you want to wait until you are in the stand before setting any scent out, and you also want to take it with you when you leave... Deer can pinpoint where a scent is coming from, and you don't want a deer to walk up to that scent wick and figure out something is up when you are not there.... But I have had good luck with this hopefully you will do the same... Also try dragging one tied to your boot behind you... and refresh is every so often cause deer can also tell which way something is walking... and just hang it in a tree 30 yards away when you get to your stand site... This works wonders especially if you have to cross any trails to get to your stand... Good Luck...
