Split the colony to relieve population pressure

Divide a strong, crowded colony into two separate hives by moving 3-5 frames of brood, nurse bees, and stores into a new hive body. The queenless split will raise a new queen from existing larvae, or you can introduce a purchased mated queen for faster recovery.

Why It Works

Splitting directly addresses the root cause of swarming: excess population relative to hive volume. Removing brood and bees drops the colony below the congestion threshold and disrupts swarm cell development. The original hive retains its queen and foraging force, while the split becomes a productive new colony within 4-6 weeks.

Steps

1. Locate the queen and confirm which box she is in
2. Move 2-3 frames of capped brood and 1-2 frames of open brood with adhering bees into the new hive body
3. Add a frame of honey and pollen to the split for immediate food
4. Place the split at least 3 feet away or at a different apiary to retain nurse bees
5. Introduce a mated queen in a cage, or confirm the presence of eggs/young larvae so bees can raise their own

Tips

• Timing matters: split when queen cells are present but still uncapped for best results
• Walk-away splits (letting bees raise their own queen) take 4-5 weeks to resume laying
• Introducing a purchased queen cuts the queenless period to 2-3 days
