Abstract: Substituted-1-arylpyrrole compounds of general formula (I) below, are useful as pesticides, in particular for the control of insects, arachnids, and nematodes. Processes to make the compounds and intermediates used for their preparation are described. Additionally, compositions containing the compounds and methods of use therefore are provided. Preferred compounds are the compounds of general formula (I) ##STR1## wherein typically preferred substituents are: X is halogen or a group R.sup.5 S(O).sub.n, in which n is 0, 1, or 2 and R.sup.5 is CH.sub.3, CF.sub.3, CCl.sub.3, CF.sub.2 Cl, CFCl.sub.2, CF.sub.2 Br, CHF.sub.2, CHCl.sub.2 or CHClF;R.sup.1 is H, F, Cl, Br, OCH.sub.3, SCH.sub.3, or CH.sub.3 optionally substituted;R.sup.2 is CN;R.sup.3 is H, F, Cl, Br, OCH.sub.3, or CH.sub.3 optionally substituted;Y is CF.sub.3, CF.sub.3 O, H, F, Cl or Br;X.sup.1 and X.sup.4 are individually H, F, Cl, Br, CH.sub.3, OCH.sub.3 or SCH.sub.3 ; andX.sup.2 and X.sup.3 are each H.
