The basic function of a queen excluder is to ensure that the queen doesn't lay eggs in the honey supers ensuring that they stay clean. Queen excluders are placed in between the brood boxes and the honey supers. They are carefully designed so that worker bees can pass through the screen while the queen can't as she is too large to fit through the openings.
Before adding a queen excluder to a hive, it's important to make sure you have given your bees enough space to store pollen, honey, and brood to successfully grow their colony throughout the season. We recommend having at least 20” of developed brood frames. This equates to a total of two filled 9 5/8” boxes or three filled 6 5/8” boxes.
If queen excluders are put on too soon or if you have not given your bees enough space, this potentially could cause your bees to swarm. Timing is of the essence when adding a queen excluder. Although using a queen excluder is a personal preference, we always use them because we hate the potential of destroying brood when extracting honey!
