PURPOSE:The titled insecticidal material which contains an oily insecticidal liquid formulation in a main material consisting of an oil penetration substrate material having a substrate color of the substrate and a ground color layer having oil penetration and low refractive index, is made transparent with existence of an insecticide to show the color of the substrate and made nontransparent by consumption of the insecticide to exhibit the ground color. CONSTITUTION:The paper material 2 consists of the main material 3 comprising the oil penetration substrate material 4 having a color of the substrate and the ground color layer 5 having oil penetration and low refractive index, and the oil nonpenetration sheet 8 attached through the substrate material 4 to the main material 3, and the main material 3 is impregnated with the mixed solution 10 of the insecticidal liquid formulation 11 (e.g., 4-methyl-4-hepten-1-in-3-yl d-cis, trans-chrysanthemate) and the auxiliary liquid formulation 12 (e.g., liquid paraffin). Since the ground color layer 5 is made transparent with existence of the uniform mixed solution 10 so the display function face 6 shows the color of the substrate. After the insecticide is evaporatd and released, since the ground color layer 5 is made nontransparent, the display function face 6 shows the ground color. The amount of the auxiliary liquid formulation inn the uniform mixed solusion is <=20wt%.
