If you got 30 bites from a mosquito, odds are that the mosquito has OD'd on your blood and has bit the dust.
Actually, I'm sorry to hear this is happening to you. Is there any chance that mosquitos are like fruit flies and like the smell of citrus? I read from someone on this board to put out a small cup of water mixed with citrus smelling dishwashing soap, and the fruit flies will drown. This is the best hint I've gotten in a heck of a long time! We're working on the third generation, so should be all eliminated soon.
