I reinforce the need to check after 3 days for more queen cells. I lost a swarm on Monday, inspected and reduced QCs to 2 on Tuesday and on Friday I found a further four when I inspected. I'm intending to leave them 2 QCs for a replacement queen and hope they don't send out a cast swarm with the spare one!

After losing a swarm if you leave an uncapped queen cell then it wont emerge for 8+ days nor will any emergency QC's. Better to leave them a week before re-inspection to knock down any emergency QC's as they will be that much more visible and after 1 week there wont be larvae of the right age for the bees to use to raise further queens (youngest larvae will be 4 days old)?
