Abstract: N-[(Alpha-perhaloalkylbenzyloxy)pyridyl]-N'-benzoylurea compounds of the following structural formula are useful insecticides: ##STR1## in which R.sub.A is selected from the group consisting of -hydrogen, -halogen, -lower alkyl, -lower alkoxy, -benzyl, and -benzyloxy;R.sub.B is selected from -hydrogen and -halogen;R.sub.C and R.sub.D are both -hydrogen or together constitute a --COCO-- bridge;R is a perhaloalkyl substitutent;R.sub.3 is selected from the group consisting of -hydrogen, -halogen and -phenylthio;R.sub.4 is selected from the group consisting of -hydrogen, -halogen, -lower alkyl, -lower alkoxy, -lower alkoxyalkyl, -lower haloalkoxy, -lower alkylthio, -lower alkylsulfonyl, and -diallylamino; orR.sub.3 and R.sub.4 at adjacent ring positions constitute a --OCH.sub.2 O--, --CH.sub.2 C(CH.sub.3).sub.2 O--, or --CF.sub.2 CF.sub.2 O-- bridge; andR.sub.5 is --hydrogen or -lower alkyl.
