Re: What to do after a swarm?
If the cells are located along the bottom of the frame they are swarm cells. I usually knock down all but one that looks the best. This will discourage after swarming which will decrease your hive population even further. Carefully handle the frame with the queen cell you have chosen, if damaged you could leave your hive hopelessly queenless. Check back in two weeks, it takes awhile for the newly hatched queen to mature enough to take her mating flight and start laying eggs. the capped brood will maintain population but it's 21 days from egg to hatch bees. To bad you didn't catch the swarm.
The Busy Bee teaches two lessons: One is not to be idle and the other is not to get stung.
