Use this 10 frame metal queen excluder with solid, riveted edges to keep the queen out of your honey supers! Made by the Pietrzak-Kubiak, the makers of our in-hive queen isolation and introduction cages, these excluders are wide enough to let worker bees through, but too narrow for the queen to pass.
Why you should choose a Pietrzak-Kubiak queen excluder:
Hint: If you are concerned that your excluder will slow your bees down when storing nectar in the supers, just turn it sideways. The bees can go around the edges, but the queen USUALLY stays in the middle of the hive and is excluded. Once you are confident your supers are drawing enough workers, you can turn the excluder to its traditional placement, but remember to check for your queen up in the supers!
