LOS ANGELES — A mosquito was found dead Friday after being exposed to a bioadvancing insect killer spray that killed thousands of mosquitoes in California, authorities said.
The California Department of Fish and Wildlife reported that more than 2,000 mosquitoes were killed by the spray, known as DEET-5.
The spray has been used for a decade, but officials said the state’s mosquito population has grown exponentially since then.
The DEET5 spray is being distributed at least once a day at least in cities, and officials say there’s been an increase in the number of mosquito bites.
The Department of Fisheries and Wildlife has also ordered a statewide emergency to be declared for the mosquito infestations, officials said.
The mosquito-killing spray was developed by the company Chemours.
Chemours said in a statement that it has “worked closely with the California Department and is committed to providing a safe and effective mosquito repellant solution to the state.”
Gavin Newsom and the state health department ordered a temporary halt on all DEET spraying in the state on Friday.
“We are asking all Californians to stay home from the water and indoors for a few days while we work to fully assess the impacts of the mosquito-borne disease outbreak,” said Newsom.
DEET5 was approved by the Food and Drug Administration in January and is sold by the Environmental Protection Agency.
It has not been approved for use in the United States.
