Baiting is not allowed in Pa, however the bear population is at an all time high and with the new muzzledloader season, extended archery seasons and in some areas additional opportunities during the firearms deer season there has never been more opportunities to harvest a PA Black Bear. With that said, success rates are still very low. The early muzzleloader and archery season presents a unique opportunity if you can find an established food source. The larger bear almost always come from big agricultural areas or near housing developments and lake vacation/ retirement communities. If you can find a farmer with standing corn who will let you hunt the early season, that is likely your high percentage opportunity.
Otherwise in the big woods, find the steepest and nastiest cover you can find near acorns and you will have a chance.
