Giant hogweed is a Federally listed noxious weed. Its sap, in combination with moisture and sunlight, can cause severe skin and eye irritation, painful blistering, permanent scarring and blindness. Contact between the skin and the sap of this plant occurs either through brushing against the bristles on the stem or breaking the stem or leaves. Please direct all giant hogweed inquiries to the NYSDEC Giant Hogweed Hotline 845-256-3111. The hotline is a place for people to report new sites, ask questions about the plant and how to control it, and connect with our statewide control project. For more information about the plant, how to identify it, how to control it, a map of NYS sites and more, visit the NYSDEC web page
