a net hat and long sleeves is about the only thing you can do short of all out chemical warfare. personally i can't stand the hats, so i just spray OFF pretty heavily and have very few bother me. that or i bring my wife out to the garden, cause if she is around they will all attack her and not me!

The hat might be a good idea anyway as so many of us are living so long we are increasingly experiencing the risk of skin cancer.
