Ah I feel your pain Newquay; they blot my summer's too. Like you, I've got Jungle Formula, little yellow bracelets they were useless, Skin so Soft, a spray of stuff from the chemist and I wear so much all encompassing clothing that I might just as well wear a duffle coat! Insect bites always turn nasty and infected on me and I've had to have antibiotic creams and tablets on several occassions. I even ended up in hospital one summer when i got bitten on the face and my airways became so swollen that I couldn't breathe properly. When you find a solution, send me a pm please.
