- if one attacks you then others will be close behind
- they cannot see in red light
- Baygon or similar is good to use as they groom each other and transfer it inside the nest
So I waited until full dark, no moon, and put several layers of red cellophane over a torch. I put on a boiler suit, gloves, and insect mesh over my head, and securely taped all the cuffs and neck with duct tape.
I took Baygon powder, and went slowly to the nest entrance where I could see a few sentries moving around. They knew something was going on, but could not see what in the red light. I dusted around the nest entrance and the "runway apron" with a good layer of Baygon and retired.
Just the one application took care of them as by the end of the next day they were gone. I am not allergic to stings BTW.

What about the ones pupating in the nest .... you'll likely have them coming out and picking up where the others left off in a few days.
We tend to get mud wasps (the big ones) and paper wasps here .... those paper wasps are nasty if you approach the nest too closely .... but a blast of Baygon Exterior Surface Spray from about a metre away sorts them.
