I bought a few years ago a Gelert anti mozzie whatever it is called. It gives off a high pitched buzz which is hardly noticeable to adults although kids can hear it and it drives them mad, anyway, I have used it many times while fishing and it really works. The mozzies just move away, you can see the swarm all around and you sit in a 12' clearing but I have never been bitten while using it and the other good anti mozzie method is to light a church candle, easily bought and again they keep the little buggers away, I used to have one lit in my bivvy while carp fishing at night again never bitten.
If you want details of the Gelert thingy, I will dig it out this weekend.
I still think your awning is still brilliant though.
