An insecticide containing polymeric composition having insecticidal activity against insect pests in the household and agriculture comprises an organic insecticide which is dispersed throughout the polymer matrix as in a monolithic manner. Through the appropriate matrix selection and attractant-porosigen compounds, the insecticide and attractant slowly migrates to the polymer surface whereby various insects, for example, ants, fire ants, cockroaches, silverfish and the larva stage of the various crawling insects that damage fruit trees, nut trees, grapes and other agricultural plants are generally destroyed through contact with said insecticide by moving on or across said polymer surface. The insecticide polymeric composition generally contains either an ethylene-propylene copolymer or a copolymer of ethylene-vinyl acetate. The insecticide can be either O,O-diethyl-O-(2-isopropyl-6-methyl-5-pyrimidinyl) phosphorothiate or 2-(1-methylethoxy) phenol methylcarbamate. The attractant-porosigen compound or agent can be soil oil or lecithin.
