Using native animal species, particularly fish, to reduce mosquito populations is popular in multiple states including Florida. This 5-page fact sheet written by Eric Jon Cassiano, Jeffrey Hill, Quenton Tuckett, and Craig Watson and published by the Program in Fisheries and Aquatic Sciences within the UF/IFAS School of Forest Resources explains how to use eastern mosquitofish to control mosquitoes. It also discusses other native fish species that may reduce mosquito populations.
