This week, workers for Orange County Mosquito and Vector Control District have been spraying pesticides from trucks, covering nearly 4,000 properties, said Lora Young, an agency spokeswoman. One spraying will cover Gilbert and Euclid streets north of Orangethorpe Avenue up to West Valencia Drive, she said. Another spraying will include West Commonwealth and West Malvern avenues, west of North Woods Avenue.
Young said between Aug. 24 and Sept.28, the agency collected 29 mosquito samples that tested positive for West Nile virus, of which 27 were found in the area scheduled to be sprayed Thursday, Oct. 4, through Saturday, Oct. 6. One of two human cases in the city this year is also from this part of Fullerton, she said.
Pesticide applications to curb mosquitoes have caused controversy over the years. In 2015, the district called off aerial spraying efforts after it failed to get a permit to fly over Disneyland. The proposal to spray from the skies caused an uproar among some county residents.
