This durable, metal 8 frame queen excluder built by Pietrzak-Kubiak, the makers of our in-hive queen isolation and introduction cages, is made with sturdy, riveted edges.
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!
