A registered trademark of Dow Chemical for a fumigant composed of sulfuryl fluoride (SO2F2 ). A colorless, odorless, toxic gas used for fumigation. Vikane is used to kill insects (ants, termites, silverfish, cockroaches, etc.) in homes and buildings. At high humidity and high temperature Vikane® can decompose to form hydrofluoric acid. Sulfuryl fluoride is gaseous at room temperature. It is applied from a compressed cylinder of liquid. The sprayed aerosol quickly becomes a gas and disperses throughout the sealed area. Vikane® is toxic to all life forms.
