I have a second swarm in a box (entrance blocked)... if you combine it... using newspaper method.. with another colony; do you have to worry about them swarming, again? The colony they will be combined with has a queen, but is my weaker hive.
I just didn't know if they had some type of swarm pheramone or something that would motivate them to leave the hive.
How long would you recommend keeping the entrance blocked (to keep the swarm in the box).
