It is carried out at each active ingredient concentration of 100,000 ppm, preferably 1-10000 ppm, and more preferably 10-20,000 ppm. The concentration of these active ingredients may deviate from these ranges depending on the form of the preparation, the method of application, the purpose, the time, the place, the occurrence of pests, and the like. For example, in the case of aquatic pests, the concentration of the active ingredient in water is below the above range, since it can be controlled even if a chemical solution having the above concentration range is applied to the place of occurrence. The application rate per unit area is that the active ingredient (a) is used in an amount of about 11 to 50,000 g, preferably 10 to 10,000 g, and the active ingredient (b) is used in an amount of about 11 to 50,000 g, preferably 1 lha. Used for 10- 10,000g. However, in special cases, it is possible to deviate from these ranges. The application is usually carried out in the usual manner: spraying (eg spraying, spraying, misting, atomizing, granulation, surface application, etc.), soil application (mixing, irrigation, etc.), surface application (application) , Dressing, coating, etc.), immersion poison bait and the like. It is also possible to feed the livestock with the above-mentioned active ingredient by mixing it with the feed to control the development and growth of harmful animals, particularly sanitary pests, in the excrement. It can also be applied by the so-called ultra low volume method. In this method, it is possible to contain 100% of the active ingredient.

When the composition of the present invention is used as a house pest controlling agent, it can be applied to a place where house pests inhabit. The habitat of house pests includes the path of house pests such as ant roads, wood and soil. The composition of the present invention can be formulated into various forms such as emulsions, solutions, suspensions, baits, dusts, pastes, and gels, and applied to home pests Since it can be fed or brought into contact with house pests, house pests can be controlled. Above all, in controlling termites and ants, (1) the method of setting the above bait to the bait method, (2) applying the above dust, paste, gel, etc. to the ant road or to the damaged area It is desirable to apply directly to 望ま.

[0020] When the composition of the present invention is applied to a pest path of a house, for example, an ant path, it is preferable to break a part of the ant path and apply the composition inside the ant path. When the composition of the present invention is applied to wood, a habitat of house pests or a path of pests, it may be sprayed or applied. When applying the composition of the present invention formulated in a dust agent, paste agent, gel agent, or the like to wood, it is desirable to perform perforation and injection treatment by making holes as necessary.

[0021] When the composition of the present invention is treated as a bait agent around an ant tract or around an ant tract, termites or ant nests can be eliminated. For example, when there is an ant path under the floor or the like, a part of the ant path is broken and the composition of the present invention is sprayed or injected. Alternatively, the present composition can be ingested and controlled by installing a bait around the building using the habit of constantly searching for food in termites. When the bait of the composition of the present invention is sprayed or placed, a foraging ant who has eaten the bait and continues to induce the feeding ground to die in a chain, or the ant collects the bait and returns it to the nest. By feeding the soldier ants, larvae, and queen ants, the bait containing the composition of the present invention can be distributed to the nest, and the nest can be broken. The bait agent can be set in a bait method such as a pay station and installed around an ant path, around an ant path, or around a building.

[0022] The composition of the present invention can be subjected to soil treatment by a method of forming a drug layer on the soil surface. More specifically, for example, when a liquid agent is to be applied to the underfloor soil of a wooden building that can be invaded by humans, it is sprayed with a power sprayer, and the emphasis is on building foundations where ant passages are easily formed. It is better to process it. When treating underfloor soil, such as bathrooms and entrances, which cannot be invaded by humans, a method of piercing with a drill and injecting chemicals into the soil from there is adopted. In addition, the composition of the present invention is applied as a granule or dust to the soil.

[0023] The composition of the present invention can also be in the form of an aerosol. The aerosol usually contains an active ingredient, a carrier and a propellant. As a carrier, a powder carrier in addition to a solvent is used. No. Further, a solvent and a powder carrier may be used in combination. Examples of the solvent include esters such as isopropyl myristate, isopropyl palmitate, isopropyl decanoate, and isopropyl laurate; and alcohols such as ethanol and isopropyl alcohol. Examples of the powder carrier include inorganic powders such as titanium oxide, aluminum oxide, kaolin, talc, silicate compounds, magnesium carbonate, and the like; synthetic resin powders such as urethane, nylon, and polypropylene; and salts such as calcium stearate. Can be mentioned. The aerosol may contain the active ingredient usually in an amount of 0.0001 to 10% by weight, a carrier in an amount of 110 to 30% by weight, and a propellant in an amount of usually 20 to 90% by weight.

When the composition of the present invention is in the form of a sheet preparation, the active ingredient compound can be usually contained in the sheet preparation at a concentration of 0.01 to 20% by weight. The sheet preparation can be produced by holding the active ingredient compound on a sheet-like carrier such as cellulose paper according to a usual method. For example, a sheet preparation can be prepared by applying a solution or dispersion containing the active ingredient compound to cellulose paper and drying. The solution or dispersion can be obtained by dissolving the active ingredient compound in an appropriate solvent, but may be diluted with water containing a surfactant or a dispersant, if necessary.

When the composition of the present invention is used for controlling house pests, the amount of the active ingredient to be treated varies depending on the method of treating the composition of the present invention, the form of preparation, and other various conditions. In general, in the case of soil treatment, 0.1- 100 g / m ^2, preferably be 0.5- 20g / m ^2; the case of wood treatment, 0.01 50 g / m ^2, desirably from 0.1- 5g / m ^2. When treated as a bait, the amount of active ingredient is about 0.01 to 10 g per location.

[0026] The composition of the present invention is excellent in controlling insect pests and soil stability, has a preventive action against house pests, and has a sustained action against house pests. In addition, such compositions can reduce drug use levels and can result in less environmental pollution and health problems.
