Unfortunately some people are more prone to attack than others, not sure why though (scent, skin characteristics, whatever?). Plenty of mozzies where i live and while i only get bitten very occassionally, my [ex]girlfriend got bitten like crazy. Recently had my mother and sister over from UK for their holiday, no problem for my mother but sister was bitten a lot - and the effect the bites had was much more severe on my sister's skin - large itchy red patches.
Remember mozzies are most active at dusk, so it's a good idea to keep external windows and doors closed in the evening, this stops them invading your house and causing misery all night as they buzz around while you try in vain to sleep.
You could consider screen doors or window screens if you really want to enjoy breezy open windows during sundown.
Covering the skin is the ultimate protection so instead of shorts and t-shirt, you could try a comfy loose cotton or linen long sleeve shirt and trousers - especially in the evening. Summer safari type clothing. Socks are a good idea because they love to bite ankles.
Mozzies hate moving air, so fit ceiling fans or get a couple of free-standing fans for your balcony/patio.
If they bother you at night and you struggle to swat them the trick is to use yourself as bait. Lurk under your bedsheet lying on your back with all skin covered except your face and ears. Lay still, relax, breath normally. The mozzie will come back after a while, buzz near your ears, then land [buzzing stops]. At this point gently click on the light and slowly raise and look around. Usually the mozzie doesn't fly off straight away but settles nearby. Look around your headboard, pillow etc and you will find her (it's the females that bite). Then creep up slowly and splat the bugger in one highly explosive action. Using this method you can clear a room of several mozzies in just a few minutes - much easier than trying to chase the invisible foe around the room!
