Compounds of formula ( I ) are described for deterring vermin, wherein R is unbranched or branched C1-C15 alkyl, which is unsubstituted or substituted by halogen, cyano or nitro; R1 and R2 are unbranched or branched C1-C12 alkyl, preferably C1-C6 alkyl, which is unsubstituted or substituted by halogen, cyano or nitro; and X and Y, independently of one another, are a straight~chain or branched alkylene bridge with 1 to 20 carbon atoms, preferably an alkylene bridge with 1 to 3 carbon atoms, which is unsubstituted or substituted by halogen, cyano or nitro. Furthermore, an essentially non-therapeutical process for deterring vermin is described, which is based on the usage of these compounds, as well as vermin~repellent compositions containing these compounds as the active ingredient, and finally the use of these compounds for producing vermin-deterring compositions and their usage in deterring vermin from animals, humans and objects. New compounds within the scope of formula ( I ) are also described.
