I know people do have problems with wasps (I've read your own tale of woe Dove...or tale of ouch) but there are few things funnier than a lone person, at a bus stop or walking along......doing "the wasp dance"!!!! I really am very unpleasant!
Bear in mind wasps become a real problem towards the end of the summer when their work is done in the nest and they basically go out causing trouble. Using a trap filled with fruit juice etc probably isn't a bad way to go!
I use the waspinator and it certainly keeps them away from that area , but then they congregate where I haven't got one , they were expensive so only got two , but I have got three years of use from them
I've hardly seen any wasps here ( West Somerset ) this year. The odd one or two coming for the fallen apples but that is about it.

Our laurel hedge was alive with wasps every summer, and then I discovered the waspinator. The wasps certainly came, and they left just as quickly and didn't return. It certainly worked for us, so it might be worth a try. If you google waspinator, you'll find all the information - just put it out before the wasps usually arrive and fill it with thin bin bags, I wouldn't bother with a balloon, it just deflates in no time. Hope it works for you if you get one. I've also found that it needs to be fairly visible to the wasps - don't let too much foliage obscure it.
