The invention relates to an insecticidal and acaricidal composition comprising a benzoylurea compound of the general formula ##STR1## wherein R.sub.1 is a halogen atom, R.sub.2 is a hydrogen atom, a methoxy group or a halogen atom, R.sub.3 is a hydrogen atom or represents 1 or 2 substituents which are selected from the group consisting of halogen, methyl and trifluoromethyl, R.sub.4 is a hydrogen atom or represents 1-3 substituents which are selected from the group consisting of halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkyl and C.sub.1 -C.sub.4 haloalkoxy, X is an oxygen atom or a sulphur atom, n is 0 or 1, and R.sub.5 is a hydrogen atom, a C.sub.1 -C.sub.6 alkyl group, a C.sub.2 -C.sub.6 alkenyl group or a C.sub.3 -C.sub.6 cycloalkyl group, with the proviso, that, if n is 0 and R.sub.5 is a hydrogen atom, R.sub.3 is a hydrogen atom. The composition may be used for the control of insects and/or mites in a dosage of 1 to 5,000 grams of active substance per hectare.
