Nice little summary here: https://teara.govt.nz/en/wasps-and-bees/page-1

Interesting that NZ has many native wasps - never knew that but may have seen them and not known what they were.

Page 3 covers our introduced paper wasps. They are definitely on a kill notice from me.

Ok so if they’re super deformed looking like in this article they can be on the no kill list. Sounds like the rest of the natives don’t look like wasps anyways. https://www.stuff.co.nz/auckland/local-news/western-leader/103326526/new-zealand-native-wasps-can-fight-pests-by-laying-eggs

Also sounds like the natives are solitary so they’re unlikely to be accidentally sprayed anyway.

Those look black and white in real life, not easily confused with Asian or European wasps. They aren't super common, but you'll sometimes see them around citrus trees. They're a beneficial insect.

All good then, I only spray them in the nest so I get a good look.

You can kill as many as you want. If the climatic and living conditions are optimal for these invasive species (and they are becoming so here in Europe due to global warming), the insects will win.

War has commenced, though the weather has not helped me much.

I've managed to get a residual insecticide sprayed all round the entrances.

But hard to tell if it's worked as the wasps havent been out and about much.

Do they hibernate all winter?

It’s not cold enough (at least in Auckland) yet.

they will be starting to die off as the available food drops off. its only the queens that hibernate over winter.

The partially constructed primary nest of the Asian hornet (Vespa velutina) in my rain-protected basement light well, which I was able to easily cut off last night with a long-handled shovel, drop into a plastic bag, and dispose of. If that hadn't been possible, I would have waited until late autumn (it's spring here right now) and simply removed it (together with a possible secondary nest) when only the queen remained.
