Explanation of the invention? ) 0. 0 to 5 to 20% by weight of 2etoxazole and 30 to 99.95% by weight of cellulose powder. Cellulose powder can be obtained by pulverizing after acid hydrolysis of wood cellulose. In addition, natural cellulose materials such as wood powder can also be used as cellulose powder. When the termite-controlling agent of the present invention is a powdery formulation, it may contain a powder carrier. Examples of the powder carrier used in the present invention include inorganic Powders such as synthetic hydrated silica, anhydrous silica, alumina, kaolin, talc, titanium oxide, and magnesium carbonate; synthetic resin powders such as polyurethane, polyamide, and polypropylene; and salts such as calcium stearate The amount of the powder carrier in the termite control formulation of the present invention is usually 0 to 69.95% by weight. The powdery formulation is usually prepared by mixing and pulverizing the powder carrier with etoxazole and cellulose powder as needed. The termite-controlling formulation of the present invention may be an aerogel formulation containing the above-mentioned powdery formulation. The aerogel formulation generally includes a powdery formulation and a propellant and a solvent as required, wherein the aerogel formulation The amount of the powdery formulation and the propellant in the substance are generally 0.1 to 10% by weight and 20 to 90% by weight, respectively. Examples of such solvents are esters such as isopropyl myristate , Isopropyl palmitate, isopropyl decanoate, isopropyl laurate, etc .; and alcohols such as ethanol, isopropyl alcohol, etc. When the termite control agent of the present invention is a plate-like formulation, the plate-like formulation is It usually contains from 0. 001 to 20% by weight of etoxazole. The plate-like formulation can be obtained by supporting etoxazole on cellulose paper by a conventional method. For example, a solution or dispersion containing etoxazole is spread on cellulose paper and It can be prepared by drying. Dissolve etoxazole in an appropriate paper size.
