Google's Mosquito Plan Aims to Combat Dengue in California and Florida
Dengue is no longer just a travel risk—what Google's mosquito plan could mean for your summer

Google is seeking federal approval to release 64 million sterilized male mosquitoes in California and Florida over two years. This initiative aims to reduce Aedes aegypti populations, which transmit dengue fever and other diseases, amid rising concerns over their spread due to climate change.
- 01Google's project, named Debug, involves releasing sterilized male mosquitoes infected with Wolbachia bacteria to reduce disease-carrying populations.
- 02California reported 18 dengue cases in 2024, with many residents at risk due to favorable conditions for mosquito transmission.
- 03The initiative could potentially prevent an additional 4.1 million residents from being at risk by mid-century due to climate change.
- 04Previous releases of sterilized mosquitoes in Los Angeles County have shown an 80% reduction in female Aedes aegypti populations.
- 05The U.S. Environmental Protection Agency is currently seeking public comments on Google's proposal before granting approval.

Google is pursuing federal approval to release up to 64 million sterilized male mosquitoes in California and Florida as part of its Debug project, aimed at combating the spread of Aedes aegypti, the mosquito responsible for transmitting dengue fever and other diseases. With nearly half of California's counties now inhabited by these mosquitoes, the state reported 18 cases of dengue in 2024, primarily in Los Angeles County. A recent study indicates that over 18 million Californians live in areas where conditions are suitable for dengue transmission, and climate change could increase this number by 4.1 million by mid-century. The Debug initiative involves infecting male mosquitoes with Wolbachia bacteria to render them sterile, which, when released, will mate with females that lay non-hatching eggs, thereby reducing the mosquito population over time. Previous efforts in Los Angeles County have demonstrated an 80% reduction in female populations. The U.S. Environmental Protection Agency is currently inviting public comments on this proposal before making a decision.
