Last year my daughter got bit so badly that both of her legs looked like she had a huge rash. It was just a string of mosquito bites combined with a sensitivity to them that exaggerated an already rough problem.
All that said, I'm not sure I'm pro-extermination. We have a lot of bats that come around and eat the mosquitos around dusk. I'm sure they'd find other things to eat, but I like seeing them skim the pool for a drink and then eat a few dozen skeeters while they dart around. I also don't like people playing god with this type of stuff. The butterfly effect is real, and if we exterminate them all, we won't know what the effect is until it's already too late. Realistically, the earth adapts to whatever we do to it. Long after we're gone, there will be tons of interesting life forms. That still doesn't make me any less uneasy about it.
I don't know.
