Fight Mosquitoes - Free Fish Wednesdays

Hillsborough County Mosquito Control has teamed up with the UF Tropical Aquaculture Lab (TAL) to host weekly mosquito fish giveways for residents of Hillsborough County, Florida. 

Residents can pick up limited quantities of free mosquito fish for use in backyard ponds, birdbaths, fountains, abandoned swimming pools, rain barrels, and other artificial containers that are common breeding sites for mosquito larvae.  The fish are available first-come, first-served and will be provided in temporary plastic travel (fish) bags, along with instructions for introducing them to their new environment. 

For more information, email Mosquito Control or call 813-635-5400.

By eating hatchlings before they turn into adult mosquitoes, mosquito fish (Gambusia) help control insects that can carry West Nile virus, Eastern equine encephalitis, St. Louis encephalitis, and Zika.  Hillsborough County Mosquito Control and UF TAL are distributing the fish at no charge to residents.

The 2 1/2-inch fish are a native freshwater species.  They are an effective, natural way to control mosquito larvae in backyard ponds, birdbaths, fountains, animal troughs, unused swimming pools, and other standing water.  They require no feeding, and care is limited to protecting them from garden sprays, chlorine, or other chemicals used for cleaning.  Mosquito fish do not lay eggs (they are live-bearing fish) and need no special environment for breeding.
