I used a plastic queen excluder in 2 hives last year, and the bees
refused to go up into my honey supers. After 2 months I figured I'd
better take it off, and a month later the supers were full. I have since
learned not to bother with it if there is a layer of honey on top of the
brood seperating the nest and the honey supers. Maybe the plastic is
"scratchy"? I wonder if wooden ones are better, or even necessary?
