First "stinggoes" is great stuff, as is any of the over the counter Hayfever treatments (all contain antihistamines which you can either take or crush them up and mix with a little saliva or petrolium jelly to make a paste and spread on the site of the bite for relief).
Second to avoid bites in the first place without the chemicals like DEET, dose up on Garlic Oil Caps & Vitamin B for a couple of days before you plan to go out and then take a couple each day to top up, this works great for Mozzies.
Third avoid wearing aftershave and deodorants, this will bring them from miles away, also avoid wearing dark coloured clothing too, the chemical fixers in the dark coloured dyes acts like a homming beacon to them too.
And finally, the greatest attractant to mozzies is our breath, they are attracted to the cabon dioxide we expell buring resperation so I'm affraid we cant do much with this particular problem.
I hope this is useful...
