With the warm weather, ample forage and growing colonies, the threat of swarming looms ever larger!
Please ensure that you are inspecting your colonies regularly for swarming activity (e.g. every 5 days for unclipped queens) and do not imagine that by merely cutting out any queen cells you will solve the problem. You need to take the correct remedial action to avoid losing your queen and half of your bees!!
We therefore recommend that you read the WBKA’s excellent pamphlet on Swarm Control (click here) and also look at how to create an Artificial Swarm.
