There are 2 types of paper wasps, Asian and Australian. Check out this
for pictures of both.
I've spent ages outside trying to find their nest.
suggests that their nests are small, about the size of a pear. And that they fly no more than 200m. So they must be close.
AAA pest control Auckland
suggests looking at dusk, so you can see them flying in.
Well, I have looked. And looked and looked. I can't see them flying in or out of my place. So that would imply they live in my place. But I can't see them in my place either.
But we've got Vespex, right? That'll deal to them. Except, no.
"Vespex® is specifically designed for wide-area control of Vespula wasp species. In New Zealand, this includes both the common wasp (Vespula vulgaris) and German wasp (V. germanica). These wasps are also known as yellow jackets in some countries." and that "Paper wasps (Polistes sp.) get the protein they need by hunting for living insects, especially caterpillars, and are not attracted to Vespex®."
says that paper wasps are good for killing garden pests, like caterpillars, of which I have many. Many many. And that paper wasps will die out in the autumn, and the queen will hibernate on her own over winter. Not sure if this applies to our climate, as we don't have hard frosts in Auckland, but fingers crossed.
So maybe I just need to stop hanging my washing out on sunny days?
And keep looking, I think.
And as for 'Do paper wasps kill bees?'. I have no idea. There doesn't seem to be an answer on the interwebs about this. So I am assuming no. Vespula wasps kill bees for sure though.
