The city will spray down pockets of Queens, Staten Island and the Bronx after officials said the city found mosquitoes carrying the West Nile virus around the city.
The virus was found in infected mosquitos recovered in Queens' Douglaston and College Point neighborhoods, as well as Old Town in Staten Island.
The Health Department reported no cases of infected humans, but said it would set more traps and kill immature mosquitoes before they can bite New Yorkers.
Health Commissioner Dr. Mary Bassett suggested that New Yorkers clear out any standing water near their homes, and cover their arms and legs when out late. New Yorkers over the age of 50 are at particular risk, she added, for serious illness from the virus.
A low-flying helicopter armed with larvicide are currently scheduled to fly over marshy, non-residential parts of Staten Island, the Bronx and Queens on Thursday, Friday and Monday, July 21 between 6 a.m. and 7 p.m.
New Yorkers can track the city's response to the virus, as well as preventative tips, on the Health Department's website.
