This study evaluated the effectiveness of emetic compounds (lithium chloride and cupric sulfate) in honey baits as a technique for preventing black bear damage in fenced beeyards. LiCl and CuSO4 in honey baits did not reduce black bear damage at beeyards. Our experience indicates that LiCl is not a suitable emetic for producing taste aversions in free-ranging black bears.
