A method of protecting keratinous material, especially wool, from attack by insects that feed on keratin, which comprises treating said material with compounds of the formula STR1 wherein X is oxygen or sulfur, each of R1 and R2 independently is alkyl, alkenyl, benzyl or unsubstituted or substituted phenyl, R3 is halogen, nitro or trihalomethyl, R4 is hydrogen, halogen or trihalomethyl, and R5 is hydrogen, halogen, methyl or methoxy. The invention also provides novel compounds of the formula (1) wherein at least one of R1 and R2 is phenyl or substituted phenyl and X is oxygen as well as compositions containing the compounds of the formula (1) and compositions which, in addition to the compounds of formula (1), also contain synthetic pyrethroids, esters of α-alkyl-substituted phenylacetic acids or substituted sulfanilides.
