Used oil/creosote posts are medicinal anti-cootie rub attractants.
As for baiting, I use straight up sour corn using only corn, yeast and water. I save the "juice" liquid poured back to the bucket to sling up high on the surrounding foliage (6 feet to 12 feet high) so the scent goes further, faster on the breezes.
I feel after just a few hours on the breeze, you are drawing from miles away. if they have plenty of food and water where they are, they will possibly ignore it. But if on the hunt, they will find you bait.
