Interesting experiment - Megabee and Corn Meal
I had two supers damaged due to wax moths so I set them out on the porch rail to freeze them overnight. Anyway they have been sitting outside for a few weeks and of course my bees find them and start taking the honey - nothing else for them to do so they might as well keep busy. I had the thought to try an experiment. I set some megabee powder between the two supers, some megabee mix with honey to make a patty on top of one of the supers and some corn meal on each side of the supers. The bees showed little interest in the megabee powder, no interest in the megabee / honey mixture, and they ate all of the corn meal I put out. Go figure.
