PURPOSE:To obtain an insecticide having excellent stability of an insecticidal ingredient and persistence of insecticidal effects in use, by using a volatile insecticidal ingredient supported on a porous polymer as an active ingredient. CONSTITUTION:An insecticide containing a volatile insecticidal ingredient, particularly preferably pyrethroid based insecticide supported on a porous polymer, preferably a polymer selected from styrene divinylbenzene based, styrene based, divinylbenzene based and acrylic acid based polymers, having >=2m<2> surface area based on 1g porous polymer and obtained by a seed polymerization method as an active ingredient. The insecticide is used as a mode in which such an active ingredient is placed in a thin type heat-resistant substance, i.e. support, e.g. thick paper, felt, gypsum board, asbestos paper having about 1mm thickness, etc., and preferably used by filling in an electric mosquito repeller, etc., capable of exhibiting insecticidal effects by heating at about 180 deg.C.
