Google is seeking federal approval to release up to 32 million sterile mosquitoes across California and Florida as part of an experimental program it claims will reduce populations of disease-carrying insects.
The tech giant has submitted applications to the Environmental Protection Agency through its specialized “Debug” program, which it says uses biological methods to target mosquitoes capable of spreading illnesses.
According to KTLA, the proposal would allow Google to release millions of male mosquitoes carrying Wolbachia, a naturally occurring bacteria that prevents successful reproduction when they mate with wild female mosquitoes.
Because male mosquitoes do not bite or transmit disease, the company argues the releases would pose minimal risk to humans while gradually reducing mosquito populations over time.
Google’s Debug program describes the approach as a way to use beneficial insects to combat harmful ones. The company says traditional mosquito-control methods, including pesticides and eliminating standing water, have become less effective or are limited in scope.
Program officials also insist that the mosquitoes are not genetically modified. Instead, the strategy relies on a bacteria found naturally in many insect species and builds on sterile insect techniques used for decades in pest control.
The proposal also arrives at a moment when many Americans are increasingly sensitive to manipulation of insect populations. Recent reports about the spread of tick-borne illnesses — including alpha-gal syndrome, a condition that can leave victims unable to eat red meat after being bitten — have generated widespread attention and concern. As stories about meat allergies, Lyme disease and other tick-related conditions circulate, some are likely to view any large-scale insect release program with heightened suspicion.
That skepticism may prove to be one of the biggest hurdles facing the project. Even if regulators ultimately conclude that the mosquito releases pose minimal environmental or health risks, convincing the public may be more difficult at a time when trust in scientific institutions, government agencies and large technology companies remains deeply polarized.
The EPA is reviewing the applications under the Federal Insecticide, Fungicide and Rodenticide Act, according to documentation published in the Federal Register.
If approved, Google would release up to 16 million mosquitoes in Florida during the first year and another 16 million in California during the second year.
The plan is now open for public review and comment through the Federal eRulemaking Portal under docket number EPA-HQ-OPP-2025-3951.
Supporters say the program could provide a new tool against mosquito-transmitted diseases without reliance on chemical pesticides. Critics, however, are likely to raise questions about environmental impact, public consent and the long-term consequences.
The timeline for EPA approval remains unclear. If authorized, the project would represent one of the largest deliberate mosquito releases ever attempted in the United States.

It’s a simple equation … which will do the most harm?
Is it worth it to have all of these diseases and not the ‘modified’ mosquitos?
Unless there is something that we are not being told, I believe that I’d go for the bugs.
But more information given to the public would be useful.
