To reduce mosquito activity and the risk of West Nile virus, the New York City Health Department will conduct its second aerial larviciding treatment of the season to marshes and wetland areas of the Bronx, Brooklyn, Queens and Staten Island from Monday, July 18 to Wednesday, July 20 between the hours of 6 a.m. to 7 p.m., weather permitting.
According to an annnouncemeent by the Health Department, the helicopter will treat only nonresidential areas. While three days are allotted for the aerial larviciding, the application may be completed in less time. In case of bad weather, application will be delayed until Thursday, July 21 to Friday, July 22 and Monday, July 25, 2022, during the same hours, added the announcement.
The Health Department monitors mosquitoes that carry the West Nile virus. “To date, no human cases of West Nile virus have been reported this season,” the annoucement said. During warm weather, mosquitoes can breed in any still water that has been standing for more than five days. In the targeted areas, existing hot and wet weather conditions can cause a rise in mosquito populations. Due to size and limited accessibility, these areas will be treated using a low-flying helicopter. The locations of aerial larviciding are identified in charts below.
West Nile virus was first found in New York State in 1999. Since 2000, 490 human cases and 37 deaths of WNV have been reported statewide. Most people infected with EEE or WNV do not develop any signs or symptoms. If illness develops, symptoms usually occur 3-15 days after the bite from an infected mosquito.
For the aerial application in marshes and wetland areas of the Bronx, Brooklyn, Queens and Staten Island, the Health Department will use larvicides to kill young mosquitoes before they grow into adults. VectoBac® GS and VectoPrime® FG contain naturally occurring bacteria and will be used for this application. “These products have been approved by the U.S. Environmental Protection Agency and the New York State Department of Environmental Conservation and will be used on mosquito breeding grounds throughout the mosquito season,” the department said in a press release.
“The most effective way to control mosquitoes is to eliminate any standing water. New Yorkers are encouraged to mosquito-proof their homes and take precautions when spending time outdoors,” it added.
Reducing exposure to mosquitoes
- Use an approved insect repellent containing DEET, picaridin, oil of lemon eucalyptus (not for children under three), or products that contain the active ingredient IR3535.
- Make sure windows have screens. Repair or replace screens that have tears or holes.
- Eliminate any standing water from your property and dispose of containers that can collect water. Standing water is a violation of the New York City Health Code.
- Make sure roof gutters are clean and draining properly.
- Clean and chlorinate swimming pools, outdoor saunas and hot tubs. Keep them empty or covered if not in use. Drain water that collects in pool covers.
Report standing water by calling 311 or visiting nyc.gov/health/wnv. For more information about West Nile virus, call 311 or visit nyc.gov.
