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 R.sub.1 and R.sub.2 independently is alkyl, alkenyl, benzyl or unsubstituted or substituted phenyl, R.sub.3 is halogen, nitro or trihalomethyl, R.sub.4 is hydrogen, halogen or trihalomethyl, and R.sub.5 is hydrogen, halogen, methyl or methoxy. The invention also provides novel compounds of the formula (1) wherein at least one of R.sub.1 and R.sub.2 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 .alpha.-alkyl-substituted phenylacetic acids or substituted sulfanilides.
A 5-phenylcarbamoylbarbituric acid compound of the formula ##STR57## wherein R.sub.1 "' is unsubstituted or substituted phenyl, R.sub.2 is alkyl of 1 to 4 carbon atoms, alkenyl of 3 or 4 carbon atoms, benzyl or unsubstituted or substituted phenyl, R.sub.3 is halogen, nitro or trihalomethyl, R.sub.4 is hydrogen, halogen or trihalomethyl, and R.sub.5 is hydrogen, halogen, methyl or methoxy, said substituted phenyl moieties being substituted by 1 to 3 substituents selected from the group consisting of C.sub.1 -C.sub.4 -alkyl or -alkoxy, chlorine, bromine, fluorine, nitro or trihalomethyl but containing at most one nitro group, at most two trihalomethyl groups and at most two alkoxy groups and the tautomeric forms and salts thereof.
