The video explains that spring is a key time for swarm prevention and catching, as increasing nectar flows cause bee populations to expand rapidly. To reduce swarming, beekeepers should harvest honey to create space and consider making splits, while also keeping a spare brood box, base, roof and full set of frames ready for catching swarms. When catching a swarm, wearing protective clothing is recommended, and a telescopic pole and container can make it easier to reach swarms in trees. Once caught, the bees should be placed into the prepared box with all frames, and a queen excluder can temporarily be used underneath the box to keep the queen and swarm together, but it must be removed within a day or two. Cutting away the branch where the swarm was clustered can also help because the queen’s pheromones may cause bees to return to that location.
The video also covers how to tell whether the queen has been successfully caught: bees marching into the box and fanning at the entrance are good signs, while bees returning to the original location may indicate the queen was missed. Other methods include finding and caging the queen directly or using bait hives with lemongrass oil or commercial swarm lures. Newly caught swarms should be checked according to their size and the season, as a very large swarm can fill a box rapidly, while most swarms take a week or two to establish comb. The discussion also covers queenless colonies, explaining that a brood frame containing eggs can allow bees to raise a new queen, while a colony that repeatedly rejects introduced queens may be hopelessly queenless and better merged with another colony.
