Twelve vetiver oils from different biogenetic and geographical origin were tested for their repellency against Coptotermes formosanus Shiraki, (Formosan subterranean termite). Despite the variety of the constituents from different origins, all vetiver oils, except one, showed repellency. The possible termite-repelling components from the different origins are discussed.
