I was scratching my head after reading your post. Not exactly sure what this means either.The last thing they want is the swarm attracting the entire bee yard.
This got me to thinking on a purely hypothetical line.They shoot the swarms? Are you pulling our collective legs? What happens when that happens - I'm trying to picture that.
Does it just blow apart the swarm so much that the accompanying bees get discouraged and drift back to their hive? Doesn't the swarm just reassemble on their queen (assuming she herself, isn't shot dead). I've heard of people shooting the swarm out of tree (severing the branch, so it falls and can be collected on the ground.) Maybe that's what you meant?
