Mosquito larvae are tiny little wrigglers that spend their time hanging upside down at the waters surface. They eat bacteria that are in the water while they make diabolical plans to eat us when they grow up. The larvae stage is easy to control. Using products like mosquito dunks or bits works really well. This is a biological product that kills mosquitos in the larvae stage. The wrigglers eat the bacteria and die.
Small fish are also effective at controling mosquito larvae provided there is enough circulation.
