To provide a chemical volatilization body obtained by kneading a pyrethroid-based insect proof component volatile at room temperature into a resin carrier to form a filament and configuring the filament into a mesh-like shape, the chemical volatilization body having an improved breeding property, with less stickiness by an insect proof component on a resin mesh surface, and being less susceptible to an effect of light even in an outdoor use.
In a chemical volatilization body obtained by kneading a pyrethroid-based insect proof component volatile at room temperature into a resin carrier to form a filament and configuring the filament into a mesh-like shape, when the filament is cross-cut and a longest diameter and a shortest diameter each passing a center of gravity of the cross section are measured, the shortest diameter is 0.2-3.0 mm and a ratio of the longest diameter/the shortest diameter is 1.2-5.0.
