I would love to know what experiences, good and bad, others here have had using queen excluders. We had wood bound metal excluders on all of our hives and removed all but one of them when we discovered hive beetles living in the crevices and running around in behind the metal. The one we did not remove we found that the bees had propolised every nook and cranny. :shock: I wish all my hives had been that clever. :grin: Does anyone use the plastic ones or the plain metal ones? How are they made? And if you don't use excluders how do you process your honey frames and keep brood out of them?
