Florida Districts Scaled Up Sterile Mosquito Releases
State authorities have accelerated the use of biological and radiation-based controls to combat rising disease risks.

Should local authorities use genetically modified or irradiated insects to combat mosquito populations in your area?
Following a locally-acquired dengue death in Tampa Bay in September 2026, Florida mosquito control districts have expanded the use of sterile male mosquitoes to suppress local populations. This initiative builds on years of testing biological and genetic interventions across the state.
Why it matters
Warmer and wetter climate conditions have accelerated mosquito-borne disease transmission while traditional chemical pesticides are showing reduced effectiveness. These alternative suppression methods now represent a critical transition in Florida's approach to public health safety.
The Lee County Mosquito Control District now produces 1 million mosquitoes weekly in a laboratory setting, with 1,000 specimens housed per 1-by-1-inch box. These efforts utilize radiation to induce male sterility, a method pioneered in the region in 1951.
The players
Florida Keys Mosquito Control District
A regional authority tasked with population management that has served as a primary testing site for genetically modified insect technology.
Lee County Mosquito Control District
A county agency managing large-scale lab production and experimental radiation-based suppression techniques.
Mosquito Mate
A biotech firm specializing in Wolbachia-based mosquito population control that partnered with local districts.
Flyttr
A technology company that conducted multi-year releases of genetically modified mosquitoes in the Florida Keys.
Environmental Protection Agency
The federal regulatory body currently reviewing data regarding the future commercial sale of genetically modified mosquitoes.
The details
Technicians sort mosquitoes at the pupae stage—the life cycle phase after larvae and before adulthood—by gender before exposing males to radiation. This process inhibits the males from producing viable offspring. To track these insects in the wild, researchers apply fluorescent powder to the bodies of released mosquitoes, which are distributed via drones, aircraft, and manual ground deployment.
Timeline
1951: Lee County pioneered irradiated insect technology.
2017: Lee County began releasing Wolbachia-infected mosquitoes.
2018: South Miami conducted a Wolbachia-infected mosquito trial.
2021-2023: Flyttr conducted annual modified mosquito releases in the Keys.
September 2026: Tampa Bay recorded a locally-acquired dengue death.
The Tech Race
Florida's operational expansion sits at the center of the EPA's federal regulatory review of genetically modified mosquitoes. State districts are positioning their infrastructure to adopt these commercial solutions should the EPA approve the technology for wider adoption.
Residents in active trial zones may see increased drone and aircraft activity used to distribute sterile mosquitoes into the local environment. While the technology is currently used for experimental suppression, residents should monitor for federal updates that could lead to broader commercial implementation.
The takeaway
The move toward biological and radiation-based control marks a shift away from traditional chemical pesticides that are failing to curb local disease risks. Watch for the upcoming Environmental Protection Agency decision, which will dictate whether districts move to commercial procurement.
