Re: 7 MM for Black Bear
Good luck with the bear hunting. Don't know if you can use bait - autumn baiting works but there is usually a lot of natural food around to compete with - berries, crops etc. Bears seem to like petroleum products, I recall many creosote treated posts that were chewed to splinters.
Suggest you spread a few cans of sardines around the location, sardines are easy to work with and seem to attract very well. Break up each fish into 1/3's - splash the oil up a few feet in branches to get the scent into the air. I used a lot of different bait, beaver is the best but used a lot of buns soaked in deep fryer grease also.
Used sardines for at the footsnare locations and to get them into livetraps.
