Hillsborough Gives Free Mosquito Fish to Help Residents Fight Mosquitoes Naturally

County Schedules Nine Mosquito Fish Giveaway Events Starting in May

Hillsborough County, Fla. (April 22, 2022) - Hillsborough County's popular mosquito fish giveaways begin in May with a kickoff event at the Keystone Recreation Center in Odessa.

Mosquito fish fight mosquitoes before the insects can bite by eating mosquito larvae. The free fish are to be placed in intentional standing water like koi ponds, horse troughs, or rain barrels. They are small enough to hide from predators, and their favorite food is mosquito larvae.

Hillsborough County Mosquito Management Services will host Mosquito Fish Giveaway events on nine dates this summer in different locations across the county, from Odessa and Lutz to Plant City and Southshore.

Last year, Hillsborough launched a new mosquito fish hatchery to breed healthy fish for the giveaways. The result has been healthier fish with a greater survival rate.

The Mosquito Management educational trailer will be on-site at each event for the first time in three years to help residents learn about eliminating mosquitoes and to illustrate the work Hillsborough County does to keep residents healthy and safe.

Things to know about the events

  • To receive fish, you need a photo ID showing that you live in Hillsborough County.
  • County staff will scan or enter your ID information into the County's mosquito database.
  • Quantities are limited, and mosquito fish will be available only while supplies last.
  • Mosquito fish facts
  • Mosquito fish are small, native freshwater fish that eat mosquito larvae.
  • Place the fish in intentional standing water such as backyard ponds, fountains, animal troughs, and unused swimming pools to effectively and naturally manage mosquito populations.
  • The fish 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 and require no special environment for breeding.
  • Mosquito Management Services' goal is for the County's entire mosquito fish supply to be raised at its headquarters, making the operation more sustainable as homegrown fish are more likely to be healthier than fish transported from farms.
