Dragonflies, also known as mosquito hawks, are some of the insect worlds most voracious predators. Not only do the adult dragonflies hunt smaller insects such as mosquitoes, but their larvae also eat the aquatic mosquito larvae. This is also why the use of insecticides can backfire in subsequent years by also depleting the populations of mosquitoes natural predators such as dragonflies.
Fish, such as guppies, are being used to a similar end in India:

though apparently they had to ensure they chose fish that didn't taste that good to humans.
