[0024] [Table 1]

[0025] [Table 2]

[0026] [Table 3]

[0027] [Table 4]

[0028] In the present invention, the composition can be used in any of the following forms: aerosol, metered dose aerosol, hand spray, mat-type mosquito repellent, liquid-type mosquito repellent, fan-type mosquito repellent, electrostatic spray device, incense, fumigation agent, resin preparation, mosquito net, bait, and patch. <Aerosol>

[0029] An aerosol is a product in which aerosol concentrate containing an active ingredient such as an insecticide and a propellant are filled into a pressure-resistant container, and the active ingredient is sprayed by pressing a button using gas pressure. When the composition is used in the form of an aerosol, in addition to the synthetic pyrethroid compound and the antioxidant, the composition contains a solvent such as a saturated hydrocarbon, a propellant such as liquefied petroleum gas (LPG), and, if necessary, a repellent, a synergist, a stabilizer, etc. The composition can be applied to aerosols disclosed in JP 2025-40416, WO 2023-095849, JP 2021-38212, JP 2024-169657, JP 2020-2037, etc.

[0030] Propellants used in aerosols include liquefied petroleum gas (LPG), dimethyl ether, fluorocarbons, carbon dioxide, nitrogen, and nitrous oxide.

[0031] The aerosol can be produced, for example, by filling a pressure-resistant aerosol container with the synthetic pyrethroid compound, the antioxidant, a solvent such as a saturated hydrocarbon solvent, and optionally a repellent, synergist, stabilizer, etc., attaching an aerosol valve to the container, filling the container with a propellant through the stem, shaking, and then attaching an actuator. Examples of the actuator include button-type and trigger-type actuators.

[0032] The aerosol is applied, for example, to spray an effective amount of the synthetic pyrethroid compound for pest control onto pests, their trails, and / or their habitats. When treating a surface, the amount of aerosol to be applied is 1 / 2 m per 1 m of treatment area. 2 The amount of synthetic pyrethroid compound applied per 1 m of the space is usually about 0.001 to 1,000 mg. 3 The amount of synthetic pyrethroid compound is usually about 0.001 to 1000 mg per spray. The spray particle size of the aerosol can be appropriately designed depending on the purpose, but may be, for example, 1 to 100 μm. Places where the aerosol can be sprayed include houses, commercial facilities, hospitals, stations, airports, factories, offices, schools, accommodation facilities, waste treatment facilities, livestock barns, warehouses, tents, vehicles, airplanes, ships, various products, the ground, forests, pastures, gutters, etc. More specifically, places where pests can pass through or live include walls, ceilings, floors, underfloor spaces, pillars, transoms, windows, screen doors, doors, or cellulose-containing materials (wood products) thereof. Spaces into which the aerosol can be sprayed include, for example, indoors, living rooms, dining rooms, closets, storage areas, Japanese-style chests of drawers, cupboards, toilets, bathrooms, storerooms, warehouses, and inside cars, and it can also be sprayed in open outdoor spaces. <Fixed-volume aerosol>

[0033] A metered-dose aerosol sprays a fixed amount of aerosol composition (containing an active ingredient such as an insecticide) with a single spray operation, and is also called a one-push formulation. When a user operates a spray member (hereinafter also referred to as a spray button) attached to an aerosol valve, a fixed amount of the aerosol composition (aerosol concentrate and propellant) in a pressure-resistant aerosol container is discharged through the aerosol valve, and the aerosol concentrate is converted into particulate spray particles by the propellant and sprayed. When the composition is used in the form of a metered-dose aerosol, the composition corresponds to the aerosol composition described above. The spray particle diameter of the metered-dose aerosol can be appropriately designed depending on the purpose, but may be, for example, 0.1 to 100 μm. The present composition can be applied to the metered-dose aerosols disclosed in JP-A-2024-71611, JP-A-2025-39267, JP-A-2021-107387, JP-A-2024-161058, JP-A-2025-65347, JP-A-2022-9637, etc.

[0034] The aerosol concentrate constituting the metered dose aerosol composition of the present invention contains at least the synthetic pyrethroid compound and the present antioxidant as active ingredients. The content of the synthetic pyrethroid compound in the aerosol concentrate is preferably 0.01 to 70% by mass / volume. When the synthetic pyrethroid compound is present in the concentrate at 0.01% by mass / volume or more, sufficient efficacy can be obtained, while when the content is 70% by mass / volume or less, productivity is improved. The lower limit of the content of the synthetic pyrethroid compound is more preferably 0.1% by mass / volume or more, even more preferably 0.3% by mass / volume or more, and particularly preferably 0.5% by mass / volume or more, and the upper limit is more preferably 65% ​​by mass / volume or less, even more preferably 50% by mass / volume or less, and particularly preferably 25% by mass / volume or less. A solvent may be added to the aerosol concentrate to adjust the viscosity of the concentrate, improve production suitability, increase the penetration of the pesticide into pests, etc. Examples of such solvents include glycol ethers, hydrocarbon solvents, alcohol solvents, aromatic solvents, and ester solvents. Water and surfactants may also be added. Examples of hydrocarbon solvents include aliphatic hydrocarbons and alicyclic hydrocarbons such as paraffinic hydrocarbons and naphthenic hydrocarbons, with kerosene such as JIS No. 1 kerosene being preferred. Specific examples include normal paraffin and isoparaffin. Typical normal paraffins have a carbon number of 8 to 16, such as Neo Thiosol manufactured by Chuo Kasei Co., Ltd. and Normal Paraffin MA manufactured by JXTG Nippon Oil & Energy Corporation. Typical isoparaffins have a carbon number of 8 to 16, such as IP Clean LX and Supersol FP25 manufactured by Idemitsu Kosan Co., Ltd. Examples of alcohol-based solvents include lower alcohols such as ethanol and propanol (normal and iso), and polyhydric alcohols such as glycerin and ethylene glycol. Examples of aromatic solvents include toluene and xylene. Examples of ester solvents include isopropyl myristate, hexyl laurate, and isopropyl palmitate. The solvent content in the aerosol concentrate is preferably 30 to 99.99% by mass / volume. Having the solvent content in the aerosol concentrate at 30% by mass / volume or more can improve productivity, while having it at 99.99% by mass / volume or less is preferable because it ensures sufficient efficacy of the synthetic pyrethroid compound. The lower limit of the solvent content is more preferably 35% by mass / volume or more, and even more preferably 50% by mass / volume or more, while the upper limit is more preferably 99.9% by mass / volume or less, and even more preferably 99.5% by mass / volume or less. The aerosol concentrate may contain other ingredients, such as preservatives, pH adjusters, UV absorbers, inorganic substances, surfactants, and solubilizing agents, as long as the ingredients do not impair the effects of the present invention. The content of the aerosol concentrate in the aerosol composition can be varied as appropriate depending on the intended use of the metered-dose aerosol and the combination with the propellant, and is not particularly limited. For example, it can be 1 to 50% by volume in the aerosol composition. When the aerosol concentrate is 1% by volume or more in the aerosol composition, the effect of the synthetic pyrethroid compound can be fully obtained. When the aerosol concentrate is 50% by volume or less, the aerosol concentrate can be sprayed as atomized particles, thereby reducing contamination of furniture, floors, walls, etc., when used indoors, for example. The content of the aerosol concentrate in the aerosol composition is preferably 3% by volume or more at the lower limit, more preferably 5% by volume or more, and more preferably 40% by volume or less, and even more preferably 30% by volume or less at the upper limit. The propellant is a medium for spraying the concentrate and is pressurized and filled into a pressure-resistant container together with the concentrate. Examples of propellants that can be used include liquefied gases such as liquefied petroleum gases (LPG) (e.g., propane, propylene, n-butane, isobutane) and dimethyl ether (DME), compressed gases (e.g., carbon dioxide, nitrogen gas, compressed air), and halogenated carbon gases (e.g., HFC-152a, HFC-134a, HFO-1234yf, HFO-1234ze). The propellant used can be selected appropriately based on its compatibility with the concentrate and the container components, such as an aerosol valve. The propellant content in the aerosol composition can be varied as appropriate depending on the intended use of the metered-dose aerosol and the combination with the aerosol concentrate, and is not particularly limited. For example, it can be 50 to 99% by volume in the aerosol composition. When the propellant content in the aerosol composition is 50% by volume or more, the aerosol concentrate can be sprayed as spray particles, making the drug more easily diffused and the drug's effectiveness more likely to last. Furthermore, when the propellant content is 99% by volume or less, the effects of the synthetic pyrethroid compound can be obtained. The propellant content in the aerosol composition is preferably 60% by volume or more at its lower limit, more preferably 70% by volume or more, and more preferably 97% by volume or less at its upper limit, more preferably 95% by volume or less. The volume ratio of the aerosol concentrate to the propellant in the aerosol composition is preferably 1:99 to 50:50, more preferably 3:97 to 40:60, and even more preferably 5:95 to 30:70. By setting the volume ratio in this range, sufficient drug effects can be obtained.

[0035] Spaces into which metered dose aerosols can be sprayed include, for example, rooms, living rooms, dining rooms, clothing cases, closets, walk-in closets, storage closets, wardrobes, Japanese-style chests and other dressers, gaps between various furniture and home appliances and floors or walls, shoe cabinets, cupboards, toilets, bathrooms, storage sheds, warehouses, the inside of cars, etc., and they can also be sprayed in open outdoor spaces. <Hand spray>

[0036] A hand spray is a product that sprays a liquid composition containing an active ingredient such as an insecticide, which is filled in a spray container, using a manual pump or the like. When the present composition is used in the form of a hand spray, the present composition is a liquid composition filled in a spray container, and in addition to the synthetic pyrethroid compound and the present antioxidant, may contain formulation aids such as alcohols, water, surfactants such as glycerin fatty acid esters, preservatives, antifungals, deodorizers, pH adjusters, chelating agents, and fragrances. As the spray container equipped with a manual pump, a known one can be used, for example, the spray container disclosed in JP 2013-234153 A can be used.

[0037] The hand spray can be produced by mixing the synthetic pyrethroid compound and the antioxidant with formulation aids such as alcohols, water, surfactants such as glycerin fatty acid esters, preservatives, antifungal agents, deodorizers, pH adjusters, chelating agents, and fragrances, which are added as needed, to prepare a liquid composition, which is then filled into a spray container equipped with a spray mechanism such as a manual pump. The liquid composition filled into the spray container typically contains 0.001 to 90% by mass of the synthetic pyrethroid compound.

[0038] The hand spray can be used by spraying it directly on pests when they invade living spaces such as the kitchen, living room, entryway, etc. It can also be used to control pests by spraying the hand spray beforehand on pest hiding places and paths such as curtains, screen doors, and under floors. The average particle size of spray particles sprayed from the nozzle of a hand sprayer can be, for example, in the range of 80 to 350 μm or 100 to 250 μm. The average particle size here refers to the 50% cumulative volume particle size of spray particles passing 30 cm from the tip of the nozzle when the spray product is pumped once. The amount of spray per push of the hand sprayer is designed appropriately depending on the situation of use, but can be designed, for example, in the range of 0.1 to 10 mL, 0.3 to 1.5 mL, etc. The shape of the spray orifice and nozzle can be designed appropriately to achieve the above-mentioned spray particle diameter and spray amount. <Mat-type mosquito repellent>

[0039] A mat-type mosquito repellent is a product in which a mat impregnated with or carrying an active ingredient such as an insecticide is placed on a heating element in the mosquito repellent and heated, causing the active ingredient to volatilize. When the present composition is used in the form of a mat-type mosquito repellent, the present composition is prepared as a mosquito repellent mat containing the synthetic pyrethroid compound and the present antioxidant. The present composition can be applied to mosquito repellent mats (including cartridge types) and mat-type mosquito repellents disclosed in JP-A-2005-348662, JP-A-2024-142738, JP-A-2007-117086, and the like.

[0040] Blank mats typically measuring approximately 2.2 cm x 3.5 cm x 0.28 cm are used to prepare mosquito repellent mats, but the shape is not particularly limited; mats of any shape can be used by appropriately adjusting the ratio of the composition to be impregnated or supported to suit the shape of the mat. Blank mat materials may be composed of fibrous or porous carriers. In the present invention, when a 2.2 cm x 3.5 cm x 0.28 cm blank mat is used, each blank mat contains, for example, 5 to 1,000 mg of a synthetic pyrethroid compound and 0.1 to 100 mg of the present antioxidant, and may optionally contain a total of 1 to 1,000 mg of an organic solvent, a total of 0.1 to 4 mg of a dye, 2 to 100 mg of a stabilizer, and 2 to 20 mg of a fragrance.

[0041] The mosquito repellent mat can be produced, for example, by impregnating or adsorbing a mixture of the synthetic pyrethroid compound, the present antioxidant, and other components, such as an organic solvent, which may be added as needed, onto a fibrous blank mat of 2.2 cm x 3.5 cm x 0.28 cm.

[0042] JP 2009-526056 A discloses a substrate having a network of pores formed by bonding granular particles, with air treatment chemicals such as synthetic pyrethroid compounds carried within the pores. Such a substrate can be attached to the air treatment device described in JP 2009-526056 A and heated to release the air treatment chemicals such as synthetic pyrethroid compounds from the substrate. The mosquito repellent mat used in the present invention also includes the substrate described in JP 2009-526056 A. That is, a substrate (corresponding to a mosquito repellent mat) containing one or more synthetic pyrethroid compounds selected from P1 to P54 and one or more antioxidants selected from Antioxidants 1 to 4 can be produced by a method similar to the method for producing a substrate disclosed in JP-A-2009-526056. The produced substrate can be attached to the air treatment device described in JP-A-2009-526056 and heated to volatilize the synthetic pyrethroid compounds.

[0043] Examples of methods for using a mat-type mosquito repellent include the following: A mosquito repellent mat containing the present composition is placed on the heating element of a typical electric mosquito repellent equipped with a heater, and the mat is heated to approximately 140 to 200°C, causing the synthetic pyrethroid compound, which is the active ingredient, to volatilize, thereby controlling pests. This procedure can be carried out in places where pests live or may live. Such places include entranceways, hallways, toilets, washrooms, bathrooms, changing rooms, verandas, balconies, attics, stairs, garages, warehouses, attic storage, pantries, bookshelves, closets, living rooms, bedrooms, dining rooms, and outdoors (e.g., gardens, yards, campsites, sports fields, forests). <Liquid-type mosquito repellent>

[0044] A liquid mosquito repellent is a product in which an absorbent wick is inserted into a bottle filled with a liquid composition containing an active ingredient, and the active ingredient is vaporized by heating the top of the absorbent wick. When the present composition is used in the form of a liquid mosquito repellent, the present composition is prepared as a liquid composition filled in a bottle of a liquid mosquito repellent (liquid composition for a liquid mosquito repellent). The present composition can be applied to liquid mosquito repellents, liquid compositions for liquid mosquito repellents, liquid-absorbent cores, etc. disclosed in JP-A-2022-64533, JP-A-2025-117447, JP-A-2009-136374, etc.

[0045] When the present composition is used as a liquid composition for a liquid-type mosquito repellent, the liquid composition for a liquid-type mosquito repellent can be obtained by uniformly mixing the synthetic pyrethroid compound, the present antioxidant, a solvent such as water or an organic solvent, and formulation aids such as a thickener, surfactant, stabilizer, preservative, essential oil or synergist, which are added as needed. The obtained liquid composition for a liquid-type mosquito repellent is filled into a bottle, an inner stopper with an absorbent wick inserted is attached, and the bottle is set in the main body of a liquid-type mosquito repellent equipped with a heater, thereby obtaining a liquid-type mosquito repellent.

[0046] A liquid-type mosquito repellent can control pests by immersing one end of an absorbent wick in a liquid composition for a liquid-type mosquito repellent, which contains a synthetic pyrethroid compound and the present antioxidant, allowing the absorbent wick to absorb the liquid composition for a liquid-type mosquito repellent, and heating the area around the other end of the absorbent wick to evaporate the absorbed liquid composition for a liquid-type mosquito repellent. The heater for heating the peripheral surface of the end of the absorbent wick may be either a heating element capable of direct heating or a heating element capable of indirect heating, but a heating element capable of indirect heating is preferred. The heating temperature is typically about 40 to 150°C, preferably 85 to 145°C. A typical example of a heating element capable of indirect heating is a ring-shaped electric heater that generates heat when electricity is applied. The above-mentioned procedure can be carried out in a location where pests live or may live. Such places include entrances, corridors, toilets, washrooms, baths, changing rooms, verandas, balconies, attics, stairs, garages, warehouses, attic storage, pantries, bookshelves, closets, storage rooms, living rooms, bedrooms, dining rooms, and outdoors (e.g., gardens, yards, campsites, playgrounds, forests), etc. <Fan-type mosquito repellent>

[0047] A fan-type mosquito repellent is generally a product that includes a holder that holds an active ingredient such as an insecticide, a fan for blowing air onto the holder, a motor for rotating the fan, and a battery for supplying power to the motor. The fan, driven by the motor, blows air onto the holder, diffusing the active ingredient into the air. When the present composition is used in the form of a fan-type mosquito repellent, the present composition is prepared as an active ingredient support for a fan-type mosquito repellent, which supports an active ingredient such as an insecticide. This composition can be applied to the fan-type mosquito repellents and active ingredient holders disclosed in JP-A-2012-147707, JP-A-2017-10, JP-A-2014-195466, JP-A-2013-13421, etc.

[0048] The support that holds the active ingredient can be, for example, a breathable material that can hold the drug, such as a fabric material such as a nonwoven fabric or a woven fabric, or a breathable foam material. The active ingredient holder for a fan-type mosquito repellent can be prepared, for example, by impregnating a fabric material such as a nonwoven fabric or woven fabric with a liquid composition obtained by mixing the synthetic pyrethroid compound, the antioxidant, and, if necessary, formulation aids such as an organic solvent, or by attaching the liquid composition to the surface of the fabric material. The obtained active ingredient holder is housed in a cartridge, case, or the like as needed, and attached to the main body of a fan-type mosquito repellent configured to blow air through the holder with a motor-driven fan to diffuse the active ingredient into the air, thereby obtaining a fan-type mosquito repellent.

[0049] A fan-type mosquito repellent (e.g., a product comprising a holder holding a synthetic pyrethroid compound and the antioxidant, a fan for blowing air onto the holder, a motor for rotating the fan, and a battery for supplying power to the motor, and configured so that the fan driven by the motor blows air onto the holder to diffuse the synthetic pyrethroid compound into the air) can control pests by turning on the fan (e.g., by turning on the power switch if the product has one), thereby rotating the fan and diffusing the synthetic pyrethroid compound into the air. The operation can be carried out in places where pests live or may live. Examples of such places include entranceways, hallways, toilets, washrooms, bathrooms, changing rooms, verandas, balconies, attics, stairs, garages, warehouses, attic storage areas, food stores, bookcases, closets, living rooms, bedrooms, dining rooms, and outdoors (e.g., gardens, yards, campsites, playgrounds, forests). <Electrostatic spraying device>

[0050] Electrostatic spraying devices are products that use electrostatic force to spray a liquid composition containing an active ingredient such as an insecticide. An example of an electrostatic spraying device is one in which a liquid composition flows through a tubular spray electrode and a voltage is applied between the spray electrode and a reference electrode (discharge electrode) located near the spray electrode. This generates an electrostatic force on the liquid composition flowing through the spray electrode, generating an electrostatic repulsion force on the liquid composition within the spray electrode, thereby atomizing the liquid and spraying it into the air. In the electrostatic spraying device, the relative positions of the spray electrode and the reference electrode are not particularly limited. For example, the reference electrode can be located opposite the spray electrode. In the electrostatic spraying device, the liquid may exhibit a cone-jet mode at the tip of the spray electrode during spraying. This type of spraying method is a well-known technique, as disclosed in, for example, Proceedings of the Royal Society, 1964, pp. 383-397. In the electrostatic spraying device, the voltage applied between the spray electrode and the discharge electrode can be appropriately set depending on the device configuration, the desired spray rate, and the like, but may be, for example, between 1 kV and 30 kV. When the present composition is used in the form of an electrostatic spraying device, the present composition is prepared as a liquid composition to which a voltage is applied in the electrostatic spraying device (liquid composition for electrostatic spraying device). The present composition can be applied to the electrostatic spraying devices disclosed in European Patent Publication No. 1399265, Japanese Patent Application Laid-Open No. 2012-167082, Japanese Patent Application Laid-Open No. 2012-158583, etc.

[0051] When the present composition is prepared as a liquid composition for an electrostatic spraying device, it can be obtained by uniformly mixing the synthetic pyrethroid compound, the present antioxidant, and formulation aids such as a solvent, which are added as needed. The electrostatic spraying device can be obtained by filling the obtained liquid composition for an electrostatic spraying device into the liquid storage tank of the electrostatic spraying device.

[0052] Pests can be controlled by applying a voltage to the liquid composition, which contains the synthetic pyrethroid compound and the antioxidant, to an electrostatic spraying device (an electrostatic spraying device filled with the liquid composition for electrostatic spraying devices, which contains the synthetic pyrethroid compound and the present antioxidant) by energizing the device (for example, by turning on the power switch if the electrostatic spraying device has one). This operation is carried out in places where pests live or may live, and examples of such places include entranceways, hallways, toilets, washrooms, bathrooms, changing rooms, verandas, balconies, attics, stairs, garages, warehouses, attic storage areas, food storage rooms, bookcases, closets, living rooms, bedrooms, dining rooms, and outdoors (for example, gardens, yards, campsites, playgrounds, and forests). <Incense>

[0053] Incense sticks are made by mixing active ingredients such as insecticides into an incense base material and molding it into a specific shape.When the end of the stick is lit, the active ingredients are vaporized and diffused along with the smoke, thereby controlling pests. When the present composition is made into incense, the present composition contains an incense base in addition to the synthetic pyrethroid compound and the present antioxidant. The present composition can also be applied to incense sticks disclosed in JP 2006-256991, Japanese Patent No. 7474916, JP 2023-52422, JP 2024-52193, JP 2022-118157, WO2020 / 195619, etc.

[0054] The incense base material may include a combustion activator / weighting agent (combustion activator and / or weighting agent) and a binder. Examples of combustion activators / weighting agents include charcoal powder, wood flour, pyrethrum extract residue powder, citrus peel powder, tea powder, coconut shell powder, diatomaceous earth, talc, clay, and kaolin. These combustion activators / weighting agents may be used alone or in a mixture of two or more. The incense base material preferably contains 50 to 80% by mass of the total amount of combustion activators / weighting agents relative to the total amount of the incense base material. Examples of binders include tabu powder, starch (alpha starch, tapioca flour, etc.), methylcellulose, carboxymethylcellulose (CMC), and pulp. These binders may be used alone or in a mixture of two or more. The incense base material preferably contains 15 to 40% by mass of the binder relative to the total amount of the incense base material. The incense base material may further contain antifungal agents, antiseptics, etc.

[0055] When the present composition is used to make incense sticks, for example, an appropriate amount of water is added to a raw material powder obtained by mixing a synthetic pyrethroid compound, the present antioxidant, and an incense stick base material, followed by kneading. The mixture is then molded using an extruder and a punching machine, and then air-dried or heat-dried to obtain incense sticks. The synthetic pyrethroid compound and the present antioxidant may not be directly blended into the raw material powder, but may be blended by molding the raw material powder and then dripping, immersing, spraying, or applying a liquid composition containing the synthetic pyrethroid compound, the present antioxidant, and an organic solvent, if necessary, onto the molded powder, followed by air-dried or heat-dried. Alternatively, incense sticks may be produced by dripping, immersing, spraying, or applying a liquid composition containing the present antioxidant and an organic solvent, if necessary, onto commercially available regular-type mosquito coils, mini-sized mosquito coils, thick-rolled mosquito coils, etc., followed by air-dried or heat-dried. In the above-mentioned production, the present antioxidant is preferably added in a dissolved state in a solvent. The shape and size of the incense coil of the present invention are not particularly limited, and it may be rod-shaped or slightly arc-shaped, or may be spiral-shaped, conical (corn-shaped), triangular pyramid-shaped, fan-shaped, or plate-shaped, etc., and the shape and size can be appropriately set depending on the purpose of use. The incense coil of one embodiment of the present invention has a cross-sectional area of ​​4 to 100 mm when viewed from the burning direction of the mosquito coil. 2 Even if the shape of the incense stick is a triangular pyramid and the cross-sectional area varies depending on the location, the cross-sectional area as viewed from the burning direction is preferably 4 to 100 mm. 2 It is sufficient if the range is within the range of 4 mm. 2 More than 15mm 2 Less than 15mm 2 Over 40mm 2 Less than 40mm 2 More than 100mm 2 The cross-sectional shape of the incense stick may be circular or polygonal, such as triangular, rectangular, pentagonal, or hexagonal. Furthermore, grooves or protrusions may be formed on the surface of the incense stick as needed, or the incense stick may have a hollow structure.

[0056] By lighting the end of an incense stick containing a synthetic pyrethroid compound and the present antioxidant (end 30 in the case of the incense stick in the shape shown in FIG. 2), the synthetic pyrethroid compound is vaporized and diffused along with the smoke, thereby controlling pests. The above-mentioned operation can be carried out in places where pests live or may live. Such places include entranceways, hallways, toilets, washrooms, bathrooms, changing rooms, verandas, balconies, attics, stairs, garages, warehouses, attic storage, pantries, bookshelves, closets, living rooms, bedrooms, dining rooms, and outdoors (e.g., gardens, yards, campsites, playgrounds, forests), etc. <Fumigants>

[0057] Fumigants are products that vaporize active ingredients such as insecticides as smoke (fine particles) when heated. When the composition is used as a fumigant, the composition may contain a self-heating base material in addition to the synthetic pyrethroid compound and the antioxidant. When the composition does not contain a self-heating base material, it can be prepared as a fumigant that is contained in a container equipped with a means for separately heating the fumigant. The present composition can also be applied to the fumigants disclosed in JP-A-2012-236813, JP-A-2022-16925, etc.

[0058] The fumigant is prepared as a solid preparation, such as a powder, granules, or tablet, containing the synthetic pyrethroid compound and the present antioxidant. Known methods are used to manufacture the fumigant, depending on the desired dosage form. For example, granular preparations can be manufactured by known methods for manufacturing granules, such as extrusion granulation, compression granulation, agitation granulation, tumbling granulation, and fluidized bed granulation. Examples of manufacturing methods using extrusion granulation include the following: First, the components of the fumigant (synthetic pyrethroid compound, the present antioxidant, solid carrier, etc.) are mixed using a kneader or the like, and an appropriate amount of water is added and mixed to obtain a mixture. The resulting mixture is granulated using a die with a desired opening diameter in a forward or horizontal extrusion granulator. The granules are then cut into desired sizes using a cutter or the like and dried. Examples of drying methods include heat drying using a conventionally known dryer. The drying temperature is not particularly limited and can be, for example, 50 to 100°C. The drying time is determined appropriately depending on the drying temperature.

[0059] Fumigation methods using the above-mentioned fumigants include known methods, such as a method in which the fumigant is placed in any container, such as a metal container or a ceramic container, and the fumigant is heated directly or indirectly, with indirect heating being preferred. Pests can be controlled by fumigating a target space using the above-mentioned fumigants. The target space is not particularly limited, and examples include spaces where pests inhabit or may inhabit, specifically bathrooms, living rooms, closets, toilets, etc. Means for indirectly heating a fumigant can be any method that can supply the fumigant with thermal energy sufficient to cause thermal decomposition of its components without burning the fumigant. For example, a method of placing the fumigant in a metal container and heating the fumigant through the metal container can be used. Heating methods that can be used include known methods, such as contacting a substance that generates heat in contact with water with water and utilizing the heat of reaction; mixing iron powder with an oxidizing agent (e.g., ammonium chlorate), or mixing a metal with a metal oxide or oxidizing agent that has a lower ionization tendency than the metal, and utilizing the heat of oxidation. Examples of substances that generate heat in contact with water include calcium oxide, magnesium chloride, aluminum chloride, calcium chloride, and iron chloride. Among these, from the viewpoint of practicality, a method in which a substance that generates heat upon contact with water is brought into contact with water and the heat of reaction is utilized is preferred, and a method in which the heat of reaction between calcium oxide and water is utilized is more preferred. The amount of fumigant used (as a fumigant) can be set appropriately depending on the volume of the target space. For example, 3 The amount is preferably 0.1 to 10 g, more preferably 0.4 to 2.0 g per unit area. The smoking treatment time (the time from the start of smoking to the unsealing of the target space) is not particularly limited, but is preferably 1 hour or more, more preferably 1.5 hours or more. <Resin formulation>

[0060] Resin formulations are resins that contain or support active ingredients such as insecticides, and are products that become effective when the active ingredients volatilize from the resin at room temperature without the need for heating or other treatments. When the present composition is made into a resin formulation, the composition contains a resin such as a thermoplastic resin in addition to the synthetic pyrethroid compound and the present antioxidant. The resin formulation can also be used as an insect repellent housed in a housing (container), as exemplified in Figure 1. This composition can also be applied to resin preparations and insect repellents disclosed in JP-A-2020-75868, JP-A-2025-21458, JP-A-2025-104531, JP-A-2010-285385, JP-A-2023-101180, JP-A-2022-112288, JP-A-2016-123390, etc.

[0061] The resin formulation can be produced, for example, by kneading the synthetic pyrethroid compound and the present antioxidant into a thermoplastic resin and molding the resulting resin, or by molding the thermoplastic resin into a predetermined shape and then coating or impregnating the resin with a liquid composition containing the synthetic pyrethroid compound and the present antioxidant. Alternatively, the resin formulation can be produced by melting and kneading the thermoplastic resin, the synthetic pyrethroid compound, the present antioxidant, and other components such as inorganic fillers in an extruder, such as a single-screw or twin-screw extruder, adjusted to a temperature of 60 to 220°C to prepare a resin composition, and then molding the resin composition into a predetermined shape by injection molding or other methods at a temperature of 60 to 220°C. In addition to injection molding, other molding methods such as extrusion molding, press molding, and vacuum molding can also be used. The amount of the active ingredient contained in the resin molded product (resin formulation) is typically 0.1 to 90% by mass of the synthetic pyrethroid compound. The resin molded product (resin preparation) may be contained in a housing (container) to be used as an insect repellent, as exemplified in FIG. 1. Such a container may have an opening. Furthermore, such a container may be provided with a hook or a hook-and-loop fastener for installation in a location where it is desired to repel pests. Conventionally known containers may be used as such containers.

[0062] Methods for using the resin preparation and the insect repellent containing the resin preparation include installing, hanging, or attaching the resin preparation or the insect repellent containing the resin preparation in a place where pests live or where pests may live or fly in. Specific examples include a method of installing the resin preparation or the insect repellent containing the resin preparation on a floor or table, a method of hanging the resin preparation or the insect repellent containing the resin preparation from a ceiling or under an eaves, and a method of attaching the resin preparation or the insect repellent containing the resin preparation to a screen door. Examples of places where resin preparations and insect repellents containing the resin preparations can be used include: outside the house, such as outside the entrance; inside the house, such as the bedroom, living room, and kitchen; pet kennels, such as dog houses and rabbit hutches; verandas and inside septic tanks; under manhole covers; tent entrances and exits, around tents, and inside tents at campsites and parks; outdoor activity areas and their surrounding areas, such as for barbecues, fishing, hiking, and gardening; around entrances and exits, exhaust vents, and electric lights in factories and workshops; and livestock sheds, such as stables, cow sheds, chicken coops, and pig sties. <Mosquito net>

[0063] Mosquito nets are made of a woven resin that contains or retains active ingredients such as insecticides. Like resin preparations, they do not require heating when used; instead, they become effective when the active ingredients seep out of the resin at room temperature. When the present composition is used for a mosquito net, the composition contains a resin such as a thermoplastic resin in addition to the synthetic pyrethroid compound and the present antioxidant. The present composition can also be applied to the mosquito nets disclosed in JP-A-2008-92944, JP-A-2012-10640, JP-A-2016-25862, etc.

[0064] Mosquito nets can be obtained, for example, by sewing a woven fabric obtained by tricot knitting, raschel knitting, or plain knitting monofilaments or multifilaments to which an insecticidal component has been applied by immersing, coating, or kneading the surface. The mosquito net is preferably sewn into a rectangular prism or truncated cone shape to suit the size of a room or bed.

[0065] Mosquito nets can be used by hanging them from the ceiling or by driving hooks into the wall. Mosquito nets are typically used to cover a room or bed only during sleep (i.e., they are not unfolded except when sleeping), but they can be used all day (i.e., unfolded even when not sleeping) if they are not particularly intrusive. When used as a mosquito net, the synthetic pyrethroid compounds on the surface of the net kill mosquitoes that transmit infectious diseases such as malaria and inhibit their blood-sucking behavior. Malaria-transmitting mosquitoes are nocturnal and begin to feed on blood after people fall asleep at night. Therefore, if a mosquito approaches a person in search of a blood source and the person is sleeping under the mosquito net, the mosquito will touch the net before approaching the person, effectively exposing itself to the synthetic pyrethroid compounds. Mosquitoes that come into contact with the synthetic pyrethroid compounds die or lose their desire to feed on blood. Furthermore, by selecting an appropriate synthetic pyrethroid compound and resin, the synthetic pyrethroid compound will not be allowed to waft indoors more than necessary, and long-term residual effectiveness can be expected. This method is environmentally safe and is preferable. The above-described fabrics can be used for purposes other than mosquito nets, such as bedding, mattresses, pillows, quilts, cushions, curtains, wallpaper, carpeting, and window, cabinet, and door screens. Further uses include geotextiles, tents, shoe insoles, clothing (socks, trousers, shirts, uniforms worn on body surfaces exposed to insect bites, etc.), and horse blankets. <Bait>

[0066] Bait is a poisonous bait made by mixing active ingredients such as insecticides with food (ingestible components) that pests prefer, and is effective in enticing pests to eat it. When the present composition is used as a bait, the present composition may contain, in addition to the synthetic pyrethroid compound and the present antioxidant, an edible component and an attractant. This composition can also be applied to baits and bait containers disclosed in JP-A-2022-86617, JP-A-2022-40302, JP-A-2022-97528, JP-A-2023-75931, etc.

[0067] The edible component is generally a component added to the bait to induce insect pests to eat it. Examples of such edible components include sugars, lipids, starches, proteins, amino acids, carbohydrates, plant flours, animal fats, plant oils, yeast extracts, and milk solids. The edible component may also function as an attractant, as described below. Attractants are generally ingredients that have the effect of attracting pests and can be colorants, flavors, fruits, plant extracts, fragrances, other animal or plant components, pheromones, or other ingredients known to attract target pests.

[0068] The bait can be prepared by kneading the synthetic pyrethroid compound, the antioxidant, and optionally added edible ingredients and attractants in a known kneader, followed by extruding the kneaded mixture into a desired shape using an extruder or cutting it with a blade, for example, to obtain a bait in the form of granules, paste, or blocks. Alternatively, the kneaded mixture can be made into tablet form using a known tablet press. The bait may optionally contain formulation aids such as thickeners, preservatives, anti-ingestion agents, emulsifiers, and fragrances. The content of the active ingredient is determined depending on the type of pest to be controlled, but may be 0.001 to 10% by mass of the synthetic pyrethroid compound relative to the total mass of the bait. The synthetic pyrethroid compound may be added directly to the bait or may be processed into a powder, wettable powder, microcapsule formulation, emulsion, oil, or other formulation before being added to the bait.

[0069] Baits can be applied by directly coating or spraying them on the habitat of the pests to be controlled or on places where their appearance is predicted (for example, floors, walls, furniture, etc.). Baits can also be applied by placing them in a bait station (a container for bait with an opening) and placing it on the habitat of the pests or on places where their appearance is predicted (for example, floors, under furniture, gaps in furniture, inside shelves, etc.). <Patch>

[0070] Patches (also called sealants) are products that contain active ingredients such as insecticides on a sheet material with an adhesive layer.They become effective when attached to clothing or other items and the active ingredients evaporate at room temperature. When the composition is used in the form of a patch, the composition is prepared as a composition held in a sheet material having an adhesive layer. This composition can also be applied to the patches disclosed in Japanese Patent No. 6814048 and JP 2019-116450 A.

[0071] A patch can be produced, for example, by preparing a sheet material including a drug retention layer (e.g., a nonwoven fabric layer) and an adhesive layer, and adding a composition containing a synthetic pyrethroid compound and the present antioxidant to the drug retention layer. In such a sheet material, a barrier film layer (e.g., a polyester sheet such as polyethylene terephthalate or polybutylene terephthalate) can be provided between the drug retention layer and the adhesive layer. The provision of a barrier film layer can prevent migration of drugs such as synthetic pyrethroid compounds to the adhesive layer (thereby preventing drugs such as synthetic pyrethroid compounds from adhering to the patch when in use). A separator that can be peeled off from the adhesive layer can also be attached to the adhesive layer. In this case, the separator is attached to the adhesive layer on the side opposite the side that contacts the drug retention layer or barrier film layer. The attachment of the separator prevents patches from sticking together before use, and by peeling the separator off during use, the patch can be attached to clothing or other surfaces due to the adhesive effect of the adhesive layer. The amount of synthetic pyrethroid compound added to one patch is preferably set so that the pest repellent effect lasts for 8 to 12 hours, and can be set at, for example, 1 to 500 mg per patch.

[0072] The patch is used by attaching one or more patches (if a separator is included, the separator is peeled off to expose the adhesive layer) to the collar or cuffs of the user's clothing, hat, etc. Patches can be used indoors, such as in the entranceway, kitchen, toilet, living room, or bedroom, in a warehouse or car, or outdoors, such as in a garden, yard, campsite, playground, or forest.
