Yeah, I know how you feel, as it has been just over 24 hours since I picked up my last swarm...waiting for the next call is killing me...we are addicted!
I never let any of the watchers get close, let alone help me. Too many things can and will go wrong. Watchers usually panic and I want them as far away from me as possible.
I once went up a tall ladder to get a swarm hanging off of a gutter...way up there. I told them all to stay away from the bees for safety sake. They all told me that was understood. Then one of them grabbed a camera to take video...no problem as I did not object....until I was starting to back down the ladder and bumped into the fellow with the camera near the top of the ladder as I was backing down with a large swarm in a box! I do not know what happened next, but he grabbed me and about took us both off of the ladder...I had taped the box shut, or I would have been scraping more than stingers off of me.
Be careful and watch the watchers!
