Google is facing backlash over plans to release millions of bacteria-infected mosquitoes in two states, a project critics have dubbed one of the largest open-air biological experiments in US history.
Backed by Google’s parent company Alphabet, the proposal seeks federal approval to deploy 32 million modified mosquitoes annually across California and Florida beginning next year.
If approved, the two-year program would result in a total of 64 million mosquitoes being released into the environment.
The aim is to reduce populations of disease-carrying mosquitoes using what researchers describe as ‘good bugs’ – males carrying a naturally occurring bacterium called Wolbachia. Male mosquitoes also do not bite.
When the infected males mate with wild females, the females still lay eggs, but the eggs fail to develop and hatch, gradually reducing mosquito populations over successive generations.
While the method has been around for decades, many Americans are outraged by the prospect of releasing millions of insects into the wild, with some declaring: ‘This must be stopped.’
Even elected officials have joined the criticism, with Tennessee Republican Representative Tim Burchett questioning why a technology company was involved in releasing millions of mosquitoes, warning against interfering with nature.
‘Have we not learned our lesson with Kudzu, Sparrows, Black Birds [and] Asian Carp? Should I go on?’ Burchett wrote on X. ‘Don’t mess with the balance of nature.’

Burchett was referring to several infamous introductions of non-native species that spread far beyond their intended use and caused significant ecological disruptions after being introduced by humans.
One X user posted: ‘I want everyone to stop and ask what interest Google has in releasing mosquitoes.
‘They’re a tech company. Not an environmental group. Not a non-profit. Not a government. A tech company.’
Another wrote: ‘There should be public consensus before anything like this is done. It’s dangerous.’
While another shared: ‘Playing God will not end well for anyone; they need to stop trying to manipulate nature and leave it as God intended it to be.’
However, lab-grown and genetically modified mosquitoes have been released across several US states, including Florida, California and Texas, since 2021 to combat disease-carrying populations.
Google’s involvement comes through Verily, a life sciences company owned by Alphabet.
In 2016, Verily launched the Debug Project, an effort aimed at reducing the spread of mosquito-borne diseases by suppressing populations of Aedes aegypti, an invasive species responsible for transmitting viruses such as Zika, dengue and chikungunya.

The current proposal targets Aedes aegypti, a human-biting mosquito known for spreading dangerous diseases including Zika, dengue fever, yellow fever and chikungunya.
According to the Debug team, roughly 40 percent of the world’s population is at risk from diseases spread by the insect, which has expanded across tropical, subtropical and even some temperate regions around the globe.
Researchers breed millions of Wolbachia-carrying males in specialized facilities before separating them from females, which are capable of biting and spreading disease.
The goal is to dramatically reduce, and potentially eliminate, local populations of Aedes aegypti.
The proposal has also drawn comparisons to a controversial mosquito project backed by the Bill & Melinda Gates Foundation.
While Gates did not directly release mosquitoes, his foundation funded research involving mosquito-control technologies. The insects, however, were not deployed in the US.
A Bill & Melinda Gates Foundation spokesperson told AFP: ‘The foundation does not fund any work involving mosquito release in the United States.’
However, the project sparked fierce backlash and fueled a wave of conspiracy theories online.
Some claimed the mosquitoes were part of a covert effort to reduce the human population, secretly deliver vaccines or mRNA technology through bites, or serve as a tool for broader government and corporate control.
Others argued that suppressing mosquito populations could disrupt ecosystems and food chains, reflecting growing distrust of public health initiatives, Big Tech and billionaire-backed scientific projects in the wake of the COVID-19 pandemic.
Not everyone opposes the proposal, however. ‘Wolbachia has been used in mosquito control programs for years with promising results,’ one X user posted.
‘Healthy skepticism is fine, but it’s worth separating science fiction fears from evidence-based public health strategies.’
The Daily Mail has contacted Debug for comment.
