I don't know if bait is legal in your state. Some folks are against bait but they think dogs are okay; and, then others are against dogs but like bait.
When bears emerge in the spring their feet are tender- so I am told- and they haven't eaten for a while so they munch on succulents, new grow, etc. (The tender feet is important as they don't travel that far and bait will keep them nearby) The bait ought to be sweets or bread that is soaked in oil of anise. This bait ought to be put in a mesh type onion bag and hung about 5' off the ground, on a tree. If you have a trail camera- set it up to determine what time the bear is hitting the bait. Sometimes you will be surprised- such as the bear hears your truck, is watching you, and hits the bait five minutes after you drive away.
You put up a new bait every day, say three loaves of old bread. Start at least 30 days before opening day. Putting out bait is a major commitment in time and money. Putting out 10 pounds of beef fat once a week. I tried that and it doesn't work. Racoons, squirrels, etc may also start working the bait so the camera is a big help.
Ideally you should know the area, the bear needs a safe way to approach (dense woods. You ought to set up a tree stand pretty close- 30 yards maximum. Some folks put a scarecrow in the stand to get a bear used to seeing something there. The actual location doesn't have to be miles from the nearest road, if bears are in the area and used to cars, etc- then 200 yards off a road ought to be fine, maybe even 100 yards in certain locations.
Some bears scratch trees. The height of these scratches and the distance between the claw marks can give you a good idea of how big the bear is.
It is best to never hang a bait on the bait tree and walk over to the tree stand tree, your scent alerts the bear to the location of the tree stand tree, keep them seperate, have a different route into the tree stand tree.
All the standard rules of hunting still apply. DON"T MOVE. Let bugs bite you, don't figet, don't scratch that itch. DON'T MOVE. Wash your clothes in scent free soap- store them in a plastic bag with dirt and leaves- put them on when you get to the hunt site. Don't put the clothes and boots on and then sit in your truck and drive for an hour or two. If the trail cam is showing the bear's approach. Walk in on the bait trail and put a line of mashmellows along that trail as a final attraction to draw in a reluctant bear.
Wounded bear can be hard to find. No tracking snow in the Spring and bear fat can plug up bullet holes so there is no blood trail. Bear's run straight so that helps. If you can have a tracking dog back at the vehicle- that would be ideal.
A LOT of work.
Is it sporting??? That's a personal issue. If bears are hanging out by a river full of salmon, aren't the salmon a "bait"? Is setting up a stand near such a location sporting?
I've done as much bait hunting for bears as I care for. Where I now live bears aren't legal and they are all over the place. I saw 4 bears in 3 days that walked right under my stand (No bait- hunting deer) but if I was to go back to bear hunting I think I'd like to try it with hounds. You need to be in good shape as you might have to run over the mountains for a number of miles. Still, I think that would be pretty exciting.
Whether baiting is or is not sporting, it is a lot of time and work if done correctly.
