Abstract

A method of combating insects, sense animals and nematodes comprising applying to insects, arachnids and nematodes and/or their environment an effective amount of at least one 5-aminopyrazole of the formula (I) ##STR1## in which R.sup.1 represents hydrogen, alkyl or halogenoalkyl, PA0 R.sup.2 represents alkyl, halogenoalkyl, unsubstituted or substituted aralkyl or unsubstituted or substituted aryl, PA0 R.sup.3 represents hydrogen, alkyl or a radical ##STR2## Ar represents unsubstituted or substituted phenyl or unsubstituted or substituted pyridyl and PA0 n represents the number 0, 1 or 2, wherein PA0 X represents oxygen or sulphur and PA0 R.sup.4 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, alkoxyalkyl, alkylthioalkyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted aryl, alkoxy, alkylthio, unsubstituted or substituted aryloxy, unsubstituted or substituted arylthio, alkylamino, dialkylamino or unsubstituted or substituted arylamino.
