Preventing the exit of the swarm from the hive: the  device is attached to the entrance, when the uterus leaves the hive, the uterus falls on the arrival board-trap, but cannot go through the dividing grid and remains either on the arrival board-trap, or through special conical holes it enters the basket from which also cannot go further. Accordingly, all the bees stay near the hive. The front lattice of the basket is sliding, which makes it easy to reach the uterus.

Control and limitation of the exit of drones: the  device is attached to the entrance, after which the bees move freely through the grates, and the drones through the cone-shaped holes enter the basket.
