A Queen Excluder is used to keep the queen from laying eggs in the honey supers. The excluder works due to the queen being larger than a normal worker bee and cannot pass through the slots in the wire.
It is normally only used during the honey season (spring/summer) and should be removed during the autumn and winter months so the bees are able to group together to keep warm.
