I made a couple candy boards last winter to overwinter with. Your typical sugar, water, and some MegaBee added in. This past spring the bees didn't seem to be touching it so I chipped it all out of the inner covers and put it in a 5 gallon pail and snapped the lid on. I have a bunch of it now and was thinking of trying to lay some chunks on top of some of my hives as they come out of winter. Do you think it is safe to still do this?? I don't see any mold but it does smell a little yeasty. If I remember right, the MegaBee smells that way out of the bag. Any thoughts? If it is bad would the bees know enough to just not take any? I will throw it all out if I have to but would rather use it up.
