After years of struggling with fume board$, nasty compounds, bee escapes, compressed air, brushing & sprint, etc., I finally tried a Michael Bush method: Take the honey super off and set it on its end on a pallet within the bee yard. Walk away overnight. Recover it early the next morning before the sun is up and the bees fly. Tried it with the first 5 supers yesterday evening/this morning. 99% of the bees had returned to their hives for the night and the remaining girls had partied so hard the night before that they did not put up much of a fight... bushed them off and put the frames in the truck. Granted, these were in-town hives behind my office, and I probably won't be comfortable doing this in my outlying bee yards... I'd have nightmares of critters, vandals, and thieves. But maybe not. I might think about a pallet to build a rough (all my carpentry is comically rough) chicken wire cage and set it on posts and fillable cans (for ants).
