BEST MODE FOR CARRYING OUT THE INVENTION The pest repellent of the present invention contains a pest repellent component and a spreading component as essential components in a liquid medium composed of an organic solvent or water. It contains an active ingredient such as an antistatic component, a water-repellent component, and an insecticidal component.

The pest repellent component is not particularly limited as long as it is a compound having a repellent action on pests. Specific examples thereof include eucalyptol, α
-Pinene, geraniol, citronellal, camphor, linalool, p-menthen-3,8-diol, terpenol, dioctyl phthalate, dibutyl phthalate,
N, N-diethyl-m-toluamide (DEET), 2-
Ethyl-1,3-hexadiol, butyl 3,4-dihydroxy-2,2-dimethyl-4-oxo-2H-pyran-
6-carboxylate (indalone), n-hexyltriethylene glycol monoether, methyl 6-n-bentyl-cyclohexene-1-carboxylate, dimethyl phthalate (DMP), 3,7-dimethyl-6-octenal (citronellal) ), naphthalene, Shitoroneru acid, 2-ethyl-2-butyl-1,3-propanediol, 2,3,4,5-bis (delta ² - butylene) tetrahydro furfural, di -m- prolyl Shinko Melo sulfonate , 2- (4-ethoxyphenyl) -2-methylpropyl-3-phenoxybenzyl ether, 1-ethynyl-2-methyl-2-pentenyl-2,2,3,3-tetramethylcyclopropanecarboxylate, 1- Ethynyl-2-methyl-2-pentenyl-2,2-dimethyl-3- (2′-methyi 1'-propenyl) such as cyclopropane carboxylate. Further, essential oils and extracts obtained from cinnamon bark, camphor, lemongrass, clover, falcon, geranium, bergamot, laurel, pine, red peach, penny royal, eucalyptus, neem, etc. are also included. One or more of these compounds can be selected and used as a pest repellent component.

Among the above compounds, it is particularly preferable to use N, N-diethyl-m-toluamide (hereinafter referred to as "DEET"). According to this pest repellent component, there is obtained an advantage that the pest repellent effect lasts for a long time and is highly safe for the human body.

The content of the pest repellent component in the pest repellent is 1.0 to 30.0% by weight, preferably 10.0 to 20.0% by weight. When the content ratio of the pest repellent component is less than 1.0% by weight, the pest repellent effect cannot be sufficiently exhibited. On the other hand, 30.
Even if pest repellent components are contained in a proportion exceeding 0% by weight,
No pest repellent effect commensurate with the amount added.

The spreading component is a binder component for holding the insect repellent component by attaching it to the mesh. As the spreading component, for example, various resins, polyhydric alcohols, or certain surfactants can be used. Specific examples of the resin include, for example, polyvinyl alcohol, cationic polymer (acrylic resin alkanolamine solution, vinylpyrrolidone / N, N-dimethylaminoethyl methacrylic acid copolymer diethyl sulfate solution, etc.), anionic polymer ( Acrylic resin alkanolamine liquid, vinyl methyl ether, butyl maleate copolymer liquid, etc.). Specific examples of polyhydric alcohols include, for example, polyethylene glycol (200, 40).
0,600,1000), 1,3-butylene glycol, and glycols such as polyoxyethylene polyoxypropylene glycol.

The content of the antistatic component in the pest repellent is 0.1 to 5.0% by weight, preferably 0.1 to 5.0% by weight.
The content is 3 to 3.0% by weight. When the content ratio of the antistatic component is less than 0.1% by weight, the antistatic effect cannot be sufficiently exerted, and dirt adheres to the surface of the screen door, and the insect repellent effect is reduced. On the other hand, when the content ratio of the antistatic component exceeds 5.0% by weight, the effect of preventing the adhesion of dirt corresponding to the content is not obtained when the mesh is sticky.

The water-repellent component is a component for imparting water repellency to a substance attached to a mesh or the like to improve water resistance.
Specific examples of the water-repellent component include a fluorine-based resin, dimethyl silicone oil, methyl hydrogen silicone oil, modified silicone oil, and an emulsion thereof. The content ratio of the water repellent component in the insect repellent is 0.2 to 5.0% by weight, preferably 0.5 to 3.0% by weight. When the content ratio of the water-repellent component is less than 0.2% by weight, sufficient water-repellency cannot be obtained, and the adhered substance has low water resistance, so that the insect repellent effect becomes insufficient. On the other hand, even if the water-repellent component is contained in a proportion exceeding 5.0% by weight, water-repellency commensurate with the added amount cannot be obtained.

As an insecticidal component, a hillethroid compound can be used. For example, pyrethrin, allethrin, phthalthrine, resmethrin, phenothrin, velmethrin and the like can be mentioned. The insecticidal component may not be contained, but when it is contained, the content of the insecticidal component in the pest repellent is 0 to 3.0% by weight, preferably 0.2 to 1.0% by weight. It is said.
