Keeping honey bee hives means swarms. A natural reproduction process, it can happen to any beekeeper, experienced and inexperienced, so you should be prepared when it occurs, as well as excited. It is a sight to behold when the swarm is in full flight. The season of swarms is nearly always in April and May here in the Mid-Atlantic, when bees are building up quickly from all the available nectar. Check out my post on Honey Bee Nectar Flow.

You can hear the humming bees from at least 100 feet away and they come out in a wave that bursts from the hive.
Extra Equipment On Hand
As a beekeeper, I have at least two hives, sometimes, three, but an experienced beekeeper will always have additional hive boxes on hand when a swarm appears. This is your opportunity to increase your bee population free of charge! The problem is catching the swarm as it can be quite tricky. Over my twenty years of beekeeping, I have caught about one half of the swarms that appeared out of my hives, and several that people have called me about on their property- maybe a dozen in total.
Honey bee start-up colonies are expensive to buy – in the neighborhood of $150 a pop- and when a swarm emerges from a newly installed hive, like it did to mine recently, you see your honey harvest evaporate into thin air. Literally the hive will decamp, taking at least 1/3 of the population along with the queen and move to greener pastures.
Close is Better
Those greener pastures might be close enough for me to capture, but more likely than not, they fly far away to land in a tree 60 feet high with no chance of hiving them up for a new colony. The remaining bees are a much smaller population and have little chance of producing excess honey for me to harvest.
Capture the Queen
Last week I had a swarm land on a nearby tree and I simply climbed a ladder and lopped the branch off and brought it down the ladder with all the bees attached and knocked them into the hive box. The key is to get the queen into the hive box and all the workers will automatically follow. For once, the whole procedure of moving the swarm into the hive went like clock work!
Before the swarm leaves the original hive, the queen lays eggs into “queen cups” or larger cells that can accommodate the larger growing queen larvae. After the swarm leaves with the old queen, the new queens will emerge from the queen cups and if there are several that emerge, they will fight to the death, until the stronger one and usually the first one to emerge, is victorious.
Way Station Cluster
Queens are too heavy to fly long distances so the swarm usually will form on a nearby structure or tree branch which scout bees have already scoped out beforehand. They cluster in the chosen spot for a few hours or a few days, until the scout bees determine where the final nest site will be.
Then the entire swarm will fly off never to be seen again by the beekeeper unless you have set up swarm traps or you are able to capture them before they leave. Their final chosen site could be an old tree cavity or between the walls of a house.
