Personally i would not touch that with a 100 ft pole. That is not what bees feed on naturally so i try to leave them with honey, keep honey frames for new packages and if i have to feed with other stuff, i use white sugar. i know, keepers have been doing it for a long time, big and commercial ones, small and backyard keepers too. i just don't think like that and that is my management style and my 2 cents.
