@liztai why are they doing that? Are they making a nest like wasps do?
@littlescraps @liztai this is a swarm - a normal part of the lifecycle of a healthy colony. The queen and roughly half of the bees leave the hive and resources and look for a new home, leaving a new queen larva and the non- flying (young) bees in the hive to prosper. If you havent already done so, conact a beekeeper - they'll take the swarm away for you.
@paul_j @littlescraps will they fly away on their own?
@littlescraps they might, if they can find a suitable home. Here in the UK, there aren't so many possibilities, and they can struggle. If you can, call a beekeeper - they will thank you for it!
