My mosquito bites are itchy! I only got three (as opposed to the zillions my brother got) but I seem to react to them worse than anyone I know, so I've got big red blobs on my arms about half a centimetre across. Ick! My brother got bites all over his hands though, somehow. But I don't think they bother him as much. 'Orrible things. I'm going to buy a whole gallon of repellent next time I go anywhere.
