The Orange County Mosquito and Vector Control district announced Thursday, Sept. 5, that it plans to spray for West Nile virus-infected mosquitoes next week in parts of Anaheim and Buena Park.
Spraying by truck, of a treatment called DeltaGard, is scheduled for 10 p.m. to 3 a.m. Tuesday, Sept. 10 through Thursday, Sept. 12 on and around North Dale Avenue and Euclid Street, south of the 91 Freeway toward Ball Road.
Vector control officials said there has been an uptick in the presence of adult mosquitoes and dead birds with West Nile virus in the area.
“Our goal is to reduce the number of adult mosquitoes infected with West Nile virus in that area,” Young said. By doing so, she said, residents will have a decreased risk of contracting the virus through a mosquito bite.
The vector control district conducted the same treatment in 2018 in Fullerton and in 2017 in La Habra.
Officials called DeltaGard a “low impact” treatment. About 1 ounce of the water-based pesticide will be sprayed per acre over 4.5 square miles, including 8,883 properties.
The treatment is not harmful to people, pets, homes or cars, officials said.
If the driver of the pesticide truck sees people in the area, Young said, the driver will stop and wait for them to disperse. Otherwise, there is no action residents need to take to prepare for the spraying.
Young said the vector control district will update its social media accounts and alert residents if further treatment is necessary.
So far, there has been one human case of West Nile virus reported in Orange County this year, a female resident of Tustin in her 50s, according to the Orange County Health Care Agency.
Last year, the virus affected 12 people in the county and resulted in one death.
