Found throughout the Southeast in ponds and canals, gambusia are commonly known as "mosquitofish." Small and unremarkable in appearance, gambusia are voracious feeders—a female can eat up to 200 mosquito larvae in one day. They are best used in small ponds with no other fish present. With a freshwater fishing license, you can trap them yourself, or check to see if your local mosquito control district office provides them.
