I would go in and start grabbing clumps of bees, with a gloved hand of course, gently and carefully, while looking out for the queen, and place them in a box or whatever. She will most likely be in the upper 1/3 of the cluster.
If you have a ton of bees, you can use the vac, but do so carefully, to not vacuum the queen.
A swarm trap with comb and pheremone even, is no match for the real deal, especially a mated queen. Their drive is to be with her, you need to catch her and cage her, and they will follow.
The hard work is done. Think of what you have left, as a swarm of bees with a queen, essentially this is what you have now.
Don't even think of throwing in the towel and spraying them!
Go back, take your time, have fun, take pics, kick some a$$ and take some names.
You CAN do it. Remember, the hard part is over.
Go back and catch you a swarm, get the queen.
So far, you have done a great job, on a very difficult cut-out, you are almost there, good luck Konas!!!
