Hay cubes

Thanks for this information. Should we also be concerned about infestation in hay cubes, and if so, what are the warning signs in addition to mold?

what about southern California?

Are these beetles present in the hay grown in the imperial valley? I have had weird stomach problems with my horse but he has always been on alfalfa and I've not seen a blister beetle before.
