Nuc boxes serve multiple purposes in beekeeping, such as queen rearing, swarm capture, and starting honey bee hives. When using a Nuc Box, you have the option to place a frame with queen cells, allowing the new queen to hatch safely without the risk of the old queen destroying the cell. During the peak of swarm season, you can strategically position a swarm lure or attractant in the Nuc Box to capture honey bee swarms that may emerge from your bee yard.
