PURPOSE:An insecticide composition having improved long-period shelf stability, obtained by blending a specific active component with a sulfur compound or a hindered phenolic compound having a molecular weight of >= a specific amount as a stabilizer. CONSTITUTION:An insecticide composition comprising a compound shown by the formula I (R is Cl, or OC2H5) as an active component is blended with one or more of (A) a sulfur compound and (B) a hindered phenolic compound having >=300 molecular weight to stabilize long-period preservation. For example, a compound (e.g., dilauryl thiodipropionate) shown by the formula II (R is 12-18C alkyl) is preferable as the component A, an ester containing an alkyhydroxyphenyl group, such as calcium bis(3,5-di-t-butyl-4- hydroxybenzylphosphonic acid ethyl ester), etc. as component B. The amount of the stabilizer blended is preferably 0.1-1,000pts.wt. based on 100pts.wt. compound shown by the formula I.
