A guy I know from one of the car forums was talking about how he'd dug a new pond on his farm, in a particularly mosquito-infested part of California.
"You're mad", everyone said, "you're just making a perfect breeding ground for mosquitoes, with that big pool and the trees providing shade!" And indeed, the mosquitoes flocked there and bred like crazy. Mosquitoes all over.
Before long, his beautiful new pond was absolutely hoaching with mosquito larvae, which the carp he'd stocked it with ate like they'd heard it was getting banned.
Now there aren't any mosquitoes for about a three mile radius.
