Google’s plan to release 64 million bioengineered mosquitoes in California and Florida is driving steep pushback, including from members of Congress.
“Why does Google have 32 million mosquitos?” Rep. Tim Burchett tweeted over the weekend. “Have we not learned our lesson with Kudzu, Sparrows, Black Birds, Asian Carp? Should I go on? Don’t mess with the balance of nature.”

The plan to release 64 million mosquitoes in California and Florida over the course of two years (32 million per year, and 16 million per state per year) is part of Google’s Debug Project, whose purpose is “to raise good bugs and release them to stop the bad bugs.”
The trick is that all 64 million released mosquitos will be sterile.
“Our good bugs are male mosquitoes that have a naturally occurring bacteria called Wolbachia, which makes them unable to have offspring with wild female mosquitoes,” the project’s official website states.
“When a wild female mates with a sterile male, her eggs won’t hatch. The population gets smaller with each generation,” the website continues.
The beautiful part of this plan is that male mosquitoes don’t bite, meaning the 64 million released mosquitoes should cause nobody any problems.
“It’s really a genius technique that has been used to completely eradicate or reduce the numbers of serious pests and vectors,” California Academy of Sciences entomologist Chris Grinter told SFGate.
There is a GIGANTIC catch, though, according to Grinter, who pointed out that researchers must be extra careful about not accidentally releasing female mosquitoes: “You don’t want to accidentally increase the mosquito population.”
Indeed.

What’s unclear is Google’s timeline. All the company has said so far is that it’d like to start releasing the mosquitoes as early as next year.
In addition, Google is still waiting for approval from the Environmental Protection Agency (EPA).
“The EPA will decide whether to greenlight Google’s request for an experimental use permit after a public comment period, which ends on 5 June,” according to The Guardian.
In its Debug website, Google argues that “a new approach” is needed because prior methods of mosquito control aren’t working as well anymore.
“Attacking mosquitoes with pesticides is unsustainable because they’re becoming less effective over time and can be toxic, [and] clearing standing water is not enough because people can never find all the places that mosquitoes breed,” the site notes. “We need a new approach.”
The website also defends the program from critics by noting that project officials will “actively work with organizations like national and local governments, community leaders, and research institutes.”
They’ll also spend time with members of the communities they intend to target so that their officials “understand local concerns and considerations.”
A blog post on the site further points to the program’s success in Singapore, where the program has “achieved 80-90% suppression” of the local mosquito population and thus drastically reduced the rate at which locals there contract dengue fever.

Despite all these positives, criticism continues to pour in from those worried that something might go wrong.
“The company that removed the logo ‘don’t be evil’ is now releasing millions of mosquitoes to ‘stop disease,'” one critic wrote on social media. “What could possibly go wrong?”
“Google is about to conduct one of the LARGEST open-air biological experiments in U.S. HISTORY,” another critic wrote. “64 MILLION bacteria-infected mosquitoes are set to be released into Florida and California — potentially causing irreversible ecosystem disruptions. This must be STOPPED.”
