Abstract: A rodent repellant composition comprises a furan derivative of the formula <FORM:0841720/IV(a)/1> p  wherein X stands for CH3CO.CH:CH.,NH2CH2 Pz NH.CH2.  (Pz being a -pyridyl) <FORM:0841720/IV(a)/2> or for .CO.R where R is .O.CH2CH2Cl, .O. CH2.CH:CH2, .NH2 or C6H5; Y stands for .CH2OH, .CH2O.COCH2 <FORM:0841720/IV(a)/3> or for .COR1 where R1 is H, C, C2Hl5 .0CH3, .OC2H5 or .OC3H7; and Alk stands for CH3, C2H5, C3H7, C4H9, C8H17, C12H25, C16H33, C18H37 or .CH2CH2Cl. together with a solution or aqueous emulsion of polyvinyl chloride or acetate. Examples given are 1. 0,53 lb. of ethyl 2-furoate tetrachloride and 0,947 lb. of polyvinyl acetate emulsion.  2. 0,38 lb. of ethyl 2-furoate tetrachloride, 0,09 lb. polyvinyl acetate emulsion and 0,53 lb. of vermiculite, 3.  0,5 lb. of ethyl 2-furoate tetrachloride, 0,10 lb. of dibasic lead phosphite and 0,40 lb. polyvinyl chloride solution.ALSO:Containers e.g. cartons, sacks, boxes or bins in which foodstuffs or other materials liable to attack by rodents are stored, are treated by dusting or spraying, painting or impregnating or in the form of an aerosol with a rodent repellent composition comprising a furan derivative of the formula <FORM:0841720/III/1> <FORM:0841720/III/2> wherein X stands for CH3CO.CH:CH., NH2.CH2., Py NH.CH2. (Py being a -pyridyl) <FORM:0841720/III/3> or for .CO.R where R is .O.CH2CH2C2, .O.CH2.CH CH2, NH2 or C6H5. stands for .CH2OH, .CH2O.COCH2Br <FORM:0841720/III/4> or for .COR1 where R1 is H, C2, C2H5 .OCH3, .OC2H5 or .OC3H7; and Alk stands for CH3, C2H5, C3H7, C4H9, C8H17, C12H25, C16H33, C18H37 or .CH2CH2C2 together with a solid carrier e.g. starch, talc, kieselguhr or vermiculite, or together with a solution or aqueous emulsion of polyvinyl chloride or acetate, or a mixture of water, isopropyl alcohol and zein. Specified active ingredient is ethyl 2-furoate tetra chloride.ALSO:Grain is rendered less liable to attack by rodents by treating it with a composition containing a furan compound of the formula:- <FORM:0841720/I/1> or <FORM:0841720/I/2> or <FORM:0841720/I/3> or <FORM:0841720/I/4> wherein X stands for CH3CO.CH: CH., NH2CH2., PyNH.CH2. (py being a -pyridyl), <FORM:0841720/I/5> or for .CO,R where R is ,O,CH2CH2Cl, ,O,CH2CH:CH2, ,NH2 or C6H5; g  stands for .CH2OH, .CH2.O ,COCH2Br. <FORM:0841720/I/6> or for .COR1 where R1 is H, Cl, C2H5, .OCH3, .OC2H5 or .OC3H7; and Alk stands for CH3, C2H5, C3H7, C4H9, CgH17, C12H25, C16H33, C18H37, or .CH2CH2Cl.  The composition, preferably, contains also solid carrier such as starch, talc, kieselguhr or vermiculite; or a solution or aqueous emulsion of polyvinyl chloride or acetate; or a mixture of water, isopropyl alcohol and zein.ALSO:A rodent repellent composition comprises a furan derivative of the formula <FORM:0841720/VI/1> or <FORM:0841720/VI/2> or <FORM:0841720/VI/3> or <FORM:0841720/VI/4> wherein X stands for CH3CO,CH : CH., NH2 CH2, PyNH,CH,2 (py being a -pyridyl), <FORM:0841720/VI/5> or for ,CO,R where R is ,O,CH2CH2Cl, ,O,CH2 CH:CH2, ,NH2 or C6H5; Y stands for .CH2OH, ,CH2,0 , COCH2Br. <FORM:0841720/VI/6> or for .COR. where R. is H, C2, C2H5, ,OCH3 ,OC2H5 or ,OC3H7; and Alk stands for CH3 C2H5, C3H7, C4H9, C8H17, C12H25, C16H33, C18H37, or ,CH2CH2Cl together with a solid carrier e.g. starch, talc, kieselguhr or vermiculite or a solution or aqueous emulsion of polyvinyl chloride or acetate, or a mixture of water, isoprohyl alcohol and resin.  Specified active ingredient is ethyl 2-furoate tetra chloride.
