Swarms are gentle IF you are gentle with them. If you get rough, they retaliate. Example: I'm holding a box of deep F about a foot below a swarm and Shirley shakes the branch. Plop, cluster falls on the top bars. We are instantly in a cloud of bees. I took some stings on my hands and wrists holding the box. Those that spilled over the edge of box were offended by getting roughed up. No other stings for either of us.
My guess is that you roughed up some bees in dislodging them from the branch. Be gentle. You can shake them off, but don't bump em off.
