What it is
A double screen board for 10-frame Langstroth hives — two layers of screen with an air gap, used to physically separate a colony while allowing scent and warmth to pass between the divisions. Used in queen rearing, two-queen management, and colony splits.
When to use it
Queen rearing: set up a queen-right colony below and a queenless cell-building colony above, separated by the screen. The upper bees get queen scent but can't reach her. Two-queen management: two laying queens in one hive, separated by a screen — during a heavy flow, two queens produce more brood and more honey than one. Splits: separate a queenless split from its parent colony overnight to prevent fighting before introducing a new queen.
Usage notes
Close the upper entrance when the colony above needs to be queenless; open it once the queen is introduced so foragers can leave. The screen lets pheromones and warmth pass freely — the colonies stay biologically connected without physical contact.
Compatibility
10-frame Langstroth. Sits between two hive bodies, functioning as a floor for the upper colony and a ceiling for the lower.
