Anything that stinks and the law allows can be used effectively for bait. Also, you have to refresh the bait like everyday or every couple of days depending on how long it's lasting. It also helps to put it in something where the bear has to work a little bit to get it out and not just sit there and eat then leave. Trust me, you'd be amazed at how fast a bear can eat. They can eat lbs of material in minutes, and once they are done they will just leave. So you want to make them work a little bit and not be able to eat your 20 lbs of doughnuts in 3 min and leave.

You don't have much to worry about in terms of safety as long as you are confident with your chosen weapon. I've trapped alot of bears and they are actually pretty slow to get really agressive, unless of course you're between a sow and her cubs so watch out for that. Also, another thing to remember, bears can't see extremely well and rely more on scents and sounds to pinpoint danger so always approach the bait with the wind inyour face and be quiet. Bears don't like to be suprised so if you get close to one, make sure the shot counts.
