Dept. of Health to spray for mosquitoes in part of Brooklyn tonight

Map of spray area

**Update: The spraying has been moved to Thursday evening due to inclement weather.**

I have received word that the Department of Health will be spraying for mosquitoes tonight, starting at 8:15 P.M., in some areas around Prospect Park and Green-Wood Cemetery (see the map at the right of this page and the DOH announcement linked to below for details). They are doing so to reduce the risk of West Nile Virus this summer.

The agency says it will be using a low concentration of the pesticide and will follow U.S. Environmental Protection Agency guidelines, but also recommends that you stay inside during the spraying if possible.

I am concerned that we had such short notice of this spraying and my staff is in touch with DOH representatives.

Here are excerpts from the DOH announcements:

Health Department Will Spray Pesticide to Reduce Adult Mosquito Populations

Spraying scheduled for parts of Brooklyn and Queens to help prevent West Nile Virus

August 1, 2011 - To reduce mosquito activity and the risk of West Nile Virus, the Health Department will spray pesticide from trucks in parts of Pomonok and Holliswood in Queens, and parts of Greenwood Heights, Park Slope and Windsor Terrace in Brooklyn, on Wednesday, August 3, 2011 between the hours of 8:15 p.m. and 6 a.m. the following morning, weather permitting. In case of bad weather, application will be delayed until Thursday, August 4, during the same hours.

Ground-based spraying will occur in Far Rockaway on Thursday, August 4 between the hours of 8:15 p.m. and 6 a.m. the following morning, weather permitting. In case of bad weather, application will be delayed until Monday, August 8, during the same hours. Recently, the Health Department received several mosquito nuisance complaints from the neighborhoods of Arverne, Somerville, Edgemere, Bayswater; Edgemere Park and Dubos Point Wildlife Sanctuary. Some mosquito breeding sites in these areas are inaccessible. The Health Department believes that the proposed nuisance ground application of adulticide will reduce the population of nuisance mosquitoes.


For these sprayings, the Health Department will use a very low concentration of Anvil®, 10 + 10, a synthetic pesticide. The use of pesticides in New York City is conducted in accordance with guidelines set by the Environmental Protection Agency (EPA) and the New York State Department of Environmental Conservation (DEC). A complete Environmental Impact Statement (EIS) is available at


And from the Department of Health's website:

If the City sprays pesticides in an area where I am, what should I do during the spraying?  If pesticide spraying occurs, DOH recommends that all individuals take the following precautions to avoid direct exposure to pesticides and reduce the risk of reactions:

  • Whenever possible, stay indoors during spraying.
  • Some individuals are sensitive to pesticides. Persons with asthma or other respiratory conditions are encouraged to stay inside during spraying since there is a possibility that spraying could worsen these conditions.
  • Air conditioners may remain on. But if you wish to reduce the possibility of indoor exposure to pesticides, set the air conditioner vent to the closed position, or choose the recirculate function.
  • Remove children's toys, outdoor equipment and clothes from outdoor areas during spraying. If outdoor equipment and toys are exposed to pesticides, wash with soap and water before using again.
  • Wash skin and clothing exposed to pesticides with soap and water.
  • Always wash your produce thoroughly with water before cooking or eating.

Anyone experiencing adverse reactions to pesticides should seek medical care or call 311 or the NYC Poison Control Center at (212) POISONS (764-7667).
