A method of combating pests which comprises applying to such pests or to a pest habitat a pesticidally effective amount of a 2-halogenoalkylthio-substituted pyrimidine of the formula <IMAGE> (I) in which R1 represents halogenoalkyl, R represents hydrogen, alkyl, alkylthio, alkoxy, halogenoalkyl, halogenoalkylthio, halogenoalkoxy, optionally substituted aryl or halogen and m represents a number 0, 1, 2 or 3. Those compounds other than 2-(difluoromethylthiomethylthio)-4,6-dimethyl-pyrimidine, 2,4-bis(difluoromethylthio)-6-methylpyrimidine and 4-(difluoromethoxy)-2-(difluoromethylthio(-6-methylpyrimidine are new.
