Found swarm cells last week in one of my colonies, didn't have spare equipment for an AS, so I destroyed all QCs. Returned today, 6 days later, with necessary equipment and found no new QCs. Queen laying nicely, although low on stores. So no AS necessary. Have I got away with it, or will they try again? Only time will tell. Last year In my apiary, all the swarming fever was well and truly over by mid July.
