Life in a Hive
The screen in the queen excluder keeps her in the brood chamber, where she lays eggs by the thousand.

Queen Excluder
The queen excluder is a framed grid that is placed directly below the first honey super. The holes are large enough to allow worker bees to pass through, but too small for the queen. This keeps her in the brood chamber and prevents her from laying eggs in the honey supers.
