PURPOSE:A cigarette beetle repellent that contains a specific fatty acid as an active igredient, thus being inexpensively available and showing the effect of preventing female beetles from ovipositing with an extremely small amount of application. CONSTITUTION:The objective repellent contains, as an active ingredient, a fatty acid of the formula (n is 6-11), e.g., n-caprilic acid, pelargonic acid, lauric acid, tridecanoic acid and so on. The fatty acids cited above are saturated monobasic acids and widely occur in nature in the form of binding with glycerol, higher fatty alcohol, etc., in animal or vegetable oil or wax, thus being readily available from them. The repellent is used in the form of a preparation such as wettable dust, emulsion, powder, granules or fine dust which is obtained by combining an above-cited fatty acid with appropriate carriers and additives. Or a sheet, for example, is impregnated with a solution containing the active ingredient and dried, then the product is used as a packaging material or it is applied to a part of package.
