Every winter I get quite a few European Wasps that make their way inside on the firewood. It's a wonder that the wasps haven't gotten even with me sometime on this "trip". I have tried a variation on the badminton racket with a rolled up newspaper - rolled lenghtwise for some extra swing - and then aim them at a suitable hard surface
I got stung really well a few years ago when a wasp hit me in the neck at about 70km/h and fell down my bike jacket. My first mistake was thinking that it was a stone thrown up by a passing car ....then the little mongrel came too and punished me for not giving way
. I had a large painful lump on my chest for a week and the mark remained for about three months. Needless to say, I haven't forgiven them and I hold every European Wasp that I see personally responsible for my pain! Is that prejudice or what?
Errr, back on the topic. Ant-Rid mixed in with your wasp bait supposedly kills wasps pretty well and they will even carry their wounded back to their nest, presumably for food. If you can get them to take the poison with them, you don't have to actually find the nest (or nests) and run the risk of getting a hammering from a defensive wasp nest. Since Ant-Rid contains Boron (present as Borax), I don't see why standard supermarket variety Borax would't work just as well. It kills ants OK if you mix it with their food.
