Thanks Glenda, I'll have to try the lavender & eucalyptus, even if I do smell like my Gran with a cold. LOL. I have read that the little B's don't like lavender & also peppermint oil.
Another remedy I came across on Google was to spray yourself with [original] Listerine mouthwash!!
We do use screens & air-conditioning at nightime, so I'm not bitten while I sleep, its just when we go out in the evening that I'm attacked.
