PROBLEM TO BE SOLVED: To provide a method for stabilizing a tralometrin aqueous solution in storage. SOLUTION: This method for stabilizing a tralomethrin aqueous solution is provided by blending an alkylsulfocaboxylic acid salt to it. The alkylsulfocarboxylic acid salt used in the present invention is a kind of an anionic surfactant and has a structure obtained by sulfonation of an ester of a carboxylic acid with various alcohols, and concretely, sodium di-2- ethylhexylsulfosuccininate, sodium di-octylsulfosuccininate, sodium oleic amidesulfosuccinate, a sodium polyoxyethylene(POE)sulfosuccinic laurate, sodium sulfosuccinic laurate, sodium POElauroylethanolamide sulfosuccinate, an alkylsulfoacetate, etc., can be cited, but a succinic acid slat is preferable.
