I've never really considered this, so I thought I'd post for other beekeepers' opinions and experience. On my local Association forum, someone posted that they had lost 2 hives - starved out. From what I gather from the thread, this person had been feeding them (and I quote) "cough drops, candy canes, and grape jelly." This was feeding during the winter only, I believe. My gut reaction is that processed people food is not good for anyone, least of all wild creatures, but I do not want to post based solely on my personal opinions. If anyone here has input, I'd be interested in hearing, and perhaps I can pass on some good information.
