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.
