July 13th, 2022 The Suffolk County Department of Public Works’ Division of Vector Control plans to treat parts of the following marshes by helicopter to control mosquito larvae. Should weather conditions prevent completion of the work, it will be continued on the next suitable day.

DPW’s Division of Vector Control is responsible for controlling mosquito infestations that are of public health importance. Vector Control crews regularly inspect marshlands that have historically produced large numbers of developing larval mosquitoes and treat the areas that have shown recent activity. Sections of marshland are treated by helicopter to prevent the densely clustered larvae from emerging as adult mosquitoes that have the ability to fly miles from the marshes into communities. According to the Vector Control and Wetlands Management Long-Term Plan, treatment of mosquito larvae reduces the risk of transmission of mosquito-borne diseases among the public as well as the need to control mosquito populations in residential neighborhoods.

Time and date of the application: July 14th - July 15th, 6:00am - 6:00pm
Method of application: Low altitude helicopter, granular application
Name of Pesticide: VectoPrime FG [Bti (Bacillus thuringiensis israelensis) and Altosid (Methoprene)] EPA# 73049-501

The products used by Vector Control are registered by the U.S. Environmental Protection Agency and the New York State Department of Environmental Conservation and are applied in accordance with the required state and federal permits.

No precautions are recommended to prepare for this spraying, as the helicopter will be flying at a very low level over marsh areas and taking other precautions to control drift into inhabited areas. Human exposure from this operation is unlikely and the products involved have no significant human toxicity.
