Yep, use smaller amounts of bait. Use only what one bear will take at a sitting. You don't want to fill them up, you just want to bait them. A bear with a full tummy isn't a good thing for hunting, you want one that is a bit on the hungry side. Also after the first bear has been to a site and ate all the bait, the next bear that comes in won't have anything to eat, so that will force that bear that if he wants to get some of the goodies you bait with, he better get there earlier next time. Believe me this works like a charm. I use only about a coffee can full of bait, and I bait every other day. Again, you don't want to fill em' up, just give them a nice snack.
Works for me!
