Our special hive nucleus, manufactured in Germany from high-quality pine wood, is designed for discerning beekeepers seeking efficiency and convenience in hive management. Compatible with both Dadant and Langstroth frames, this nucleus facilitates various beekeeping tasks, from capturing wild swarms to forming new nuclei, introducing bees from other hives, and monitoring without opening it. It has a capacity for 7 frames, providing sufficient space for efficient bee management.
Seven-frame pine nucleus box built for catching and handling swarms: a queen excluder on one side, a ventilation mesh on the other and a round funnel opening in the lid.
A «Feglingskasten» is the box for a shaken swarm. The German name describes exactly what it does: take bees by the shakeful and hold them properly until they are housed.
01 · THE SIDE EXCLUDER
One side carries a queen excluder with a hinged ramp. Tip the swarm onto it and the workers walk in while the queens cannot pass.
It solves what nobody enjoys discovering late: an afterswarm can arrive with several virgin queens. Filtering them at the door leaves one inside and stops the box swarming again three days later.
02 · THE TOP OPENING
The lid has a round opening made for a funnel. With it you can pour in bees shaken from other hives without them escaping round the sides.
It is how you make up a package of bees, or reinforce a caught swarm that came light, and it takes a minute per hive.
03 · THE MESH IS NOT A DETAIL
The opposite side is mesh, and it does two things. The first is visible: you can look inside without opening, so the swarm is not disturbed every time you want to know how it is doing.
The second is the one that really matters: ventilation. A swarm shut in an airless box climbs in temperature within minutes, and that is why swarms are lost on the drive home.
04 · IF IT COMES QUEENLESS
When the swarm turns out to have no queen, the box itself solves it: it takes Dadant and Langstroth frames, so you give it one with eggs and young larvae from another hive and the bees raise their own.
Keep the calendar in mind: from the egg, a queen takes 16 days to emerge, and she still has her mating flights before she starts to lay.
