If they are vacuumed in the daytime there will be bees left behind. That is a fact. Sometimes more sometimes less. As so with any shake. Any others will be trying to get to the queen at the exhaust of the vacuum. I simply face them as well... I have found this is also a way to know when the queen has been vacuumed..
Vacuuming may be quicker but certainly not as much fun.

I have had some good experiences vacuuming swarms. I haven't had that trouble in my experience but instead had some good success vacuuming swarms, leaving almost 'none' behind. It takes a little bit but any straggles will come right back to the spot where the queen was last. What I do is put the end of the hose at that spot with the vacuum still running, (where the cluster was before vacuuming), for about 5 minutes after the bulk has been vacuumed, and the last few will usually get sucked in as they search for the queen.

certainly not as much fun.I enjoy doing it the old way as well, but the fun depends on where they are located.. lol
