摘要： PROBLEM TO BE SOLVED: To provide a double layered pellet for insect-proof resin, which can include a pyrethroid-based insect-proof compound in high content in the resin without containing an insect-proof compound-adsorbing substance such as a granular inorganic filler, and can be preserved for a long period without bleeding the insect-proof compound to the surface thereof, wherein the insect-proof compound transpires gradually from an insect-proof product molded from the pellet so that the insect-proofing effect lasts for a long period.SOLUTION: A double layered pellet is configured by having an olefinic resin composition containing a pyrethroid-based insect-proof compound, under non-existence of an inorganic filler, as a core material layer, and having an olefinic resin (b) covered on the outer peripheral surface of the core material layer, the olefinic resin being free of a polar group compatible with an olefinic resin (a) composing the olefinic resin composition, wherein the olefinic resin (a) comprises an ethylene-methyl methacrylate copolymer by itself, or a resin mixture of the copolymer and another olefinic resin.
