Application to Take Place August 8-10, Between 6:00 A.M. and 9:00 P.M., Weather Permitting

The New York City Department of Health and Mental Hygiene (DOHMH) announced today that it will apply larvicide by helicopter to non-residential marsh and wetland areas of Staten Island. Surveillance has shown sustained West Nile viral activity in Staten Island and continued findings of Culex salinarius mosquitoes – a species known to transmit West Nile virus (WNV) to humans. While there has been intense mosquito activity this season, no human cases of West Nile virus (WNV) have been identified in New York City to date.

The application is scheduled for Thursday, Friday, and Saturday August 8-10, between the hours of 6:00 A.M. and 9:00 P.M., weather permitting. While three days are allotted for this activity, if weather permits, the larvicide application may be completed in less time.

The marsh (non-residential) areas to scheduled to be treated are: the Saw Mill Marsh area between Chelsea and Bloomfield; the GATX Industrial Park in Gulfport; marsh areas south of the Staten Island Expressway, west of South Avenue, and north of the Staten Island Expressway; and areas adjacent to Richmond Creek in La Tourrette Park. Because of their size and difficulty to reach by ground-based vehicles, these marsh and wetland areas will be treated with larvicide by low-flying helicopters.

The larvicide product (VectoLex CG, a natural bacterial agent) is the same product DOHMH used last year, and will continue to use throughout the mosquito season to treat catch basins and other areas of standing water. This aerial application of larvicide should not be confused with targeted, ground-based application of the pesticide Anvil scheduled for tomorrow evening in northern Staten Island.

Updates of positive West Nile virus findings in New York City can be found at DOHMH recommends that New Yorkers continue to eliminate standing water around their homes, take personal precautions against mosquitoes, and report dead birds to the City's WNV Information Line, 1-877-WNV-4NYC (1-877-968-4692) or at DOHMH's Web site
