Sorry if I jumped the gun on the reply. The stink pails don't last long. I hang them buy a rope above the bait. Cut or drill a few holes in the lid and leave it. The bait is in the barrels below and the grease is all around the barrels. The theory behind the stink bait is that a bear will be attracted to the smell and pull it down, be covered in stink and grease and then leave. Now it will leave a scent trail for other bears to follow back to the bait site. It just speeds up the whole process of having multiple bears at the bait in a hurry.
The only meat I use in my actual bait is beaver. Black bears love beaver
