Benzyl esters of the formula ##STR1## in which n is 1,2,3,4, or 5, R.sup.2 is hydrogen, C.sub.1-4 -alkyl, cyano or ethynyl, R.sup.3 is the radical of a carboxylic acid customary in pyrethroids or pyrethroid-like compounds, and at least one R.sup.1 is fluoroalkoxy or fluoroalkylmercapto, or two together are fluoromethylene- or fluoroethylene-dioxy, and the others, if present, are hydrogen or various radicals, which possess arthropodicidal properties. Various alcohols, amines, aldehydes, halides, and the like, corresponding to the alcohol moieties of the esters are also synthesized.
