Minny - thanks, I might try the oils, and also the patches if I can find them.

Heva&Zacky - it's awful isn't it, seeing the bites on them in the morning. I'm trying to avoid a mosquito net, as DS sleeps in my bed I'd have to put hooks in the ceiling. Also I know what a PITA they can be, I used one for about a year and a half and the little suckers would get in through any gaps or tiny holes, but I lived in a place where malaria was rampant so I had no choice but to use one.

Thanks Noni, I'll find out about the tea tree oil. I wonder how garnet would work?

I also thought of citronella candles, might give that a go during the day but obviously not a good idea for over night.
