lemon balm works, too.

Actually, almost any strong-smelling herb works - particularly the lemon-scented ones. And if an unually brave mosquito happens to bite you, just rub on a crushed leaf and it will ease the sting.

This is why many people plant strong-smelling herbs around their barbecue areas. The trick is, of course, that the leaves must be disturbed in some way - rubbed against, crushed - to release those essential oils. Of course, some of those insectidical herbs can help flavour your barbecue meat, too!!
