My newly swarmed hive just came under attack from a group of slightly larger bees with black abdomens. I've closed up the entrances as much as possible and they are still fighting.
Toughts?

Throw a sheet over it and aim a sprinkler at it. Be sure they have ventilation while they are closed up. Why I have screened bottom boards

Maybe they are kicking out drones?
