This was two Honey Bee colonies that moved in this ceiling about 1-1/2 months prior to the relocation. Honey bees reproduce by swarming. A parent colony will make more queens with the Queen laying eggs in a queen cell usually a minimum of 4 to 20. The original Queen will swarm a couple of days before they hatch taking a third of the grocery’s and bees, leaving the hive landing in a bush or tree close to the original location. They then scout for a new location to make a home moving in locations like this. The remaining queens are hatched and ready to fly in around 19 to 20 days sometimes swarming a couple more times, while one will stay at the original location.
