SAN DIEGO — Vector control inspectors were scheduled to go door-to-door Saturday in the Grant Hill area, notifying residents of their plan to spray for mosquitoes on Monday, according to county officials.

The county’s plan to hand-spray the neighborhood to kill invasive Aedes mosquitoes comes after mosquitoes and larvae were found in an area near the home of a resident who became infected with the Zika virus while traveling outside the country, according to spokeswoman Alex Bell.

Testing done at the San Diego County Public Health Laboratory confirmed that the person had the Zika virus, which was not acquired in the United States. The person had recently visited a country where tropical, mosquito-borne illnesses including the Zika virus are active and developed symptoms after returning home, Bell said.

The spraying area is bordered on the north by Island Avenue, on the south by K Street and on the west by Dodson Street. The eastern border is midway between 30th and 31st Streets. Vector Control plans to spray Monday, weather permitting.

To date, no Aedes mosquitoes have been found to be infected with the Zika virus in San Diego County or California.

“We can’t stress enough that it’s very important for people to inspect in and around their homes and dump out any standing water so these mosquitoes can’t breed,” County Environmental Health Director Elise Rothschild said. “They can breed in the trays under flower pots, in holes in trees, toys in the yard that can collect sprinkler water — anything that can collect water.”
