Fish and turtles are common types of animals that feed on mosquito larvae. Both small fish and small turtles will feed on mosquito larvae until they reach a certain size where they prefer to eat larger meals. However, mosquitofish will always eat any mosquito larvae because they will not grow more than about 3 inches. The District provides free mosquitofish for ponds, horse troughs, large fountains, and other water sources. If you would like mosquitofish, contact our office at 559-732-8606 or toll-free at 877-732-8606 during regular business hours. Since mosquitoes breed in stagnant water, maintaining a constant flow of water in the pond reduces mosquito breeding.
