I was dong some research on a wasp I had killed and the mite that was attached to its thorax, I ran across several articles about a wasp problem in New Zealand. Just wanted to let anyone interested that "dish-washing soap" with water (about 10 drops per 8oz RMV) works well as a wasp control agent. If squirted (sprayed) or tossed, mixed into a cup or glass or water, onto the wasp and wasp nets it will suffocate the wasp as they breath through their exoskeleton, and doesn't harm you or the environment.

I use this all the time, in fact you can spray one down while in flight, if you get enough on one it will drop like a rock. And yes, Nerf super soaker (water gun) work well.

Wish New Zealand luck on controlling the wasp population.
