I'm gonna say 18 so far. I call a swarm anything I can shake in a box, even though today's flew in on Saturday, I had to remove bricks to get to them, so I'm calling it a cut out.
Btw, I had two swarm calls today I couldn't get to, one on a tree, I'll ivestigate that tomorrow. The other one was weird. This guy wet them and bagged them, then drove them about 6 miles down the road and let them go.
