Description

[Technical Field]

[0001] The present disclosure relates to animal repellents, animal repellent aerosol products, animal repellent devices, animal repellent tablets, and animal repellent methods for repelling animals. [Background technology]

[0002] Rats, a type of animal, are known to invade homes and buildings, causing various damage. For example, when rats excrete feces and urine indoors, they are left there, making the house dirty and causing unpleasant odors. Rats also transmit bacteria, which can lead to the outbreak of infectious diseases. Rats can also be infested with mites and fleas, which can pose health risks to people and pets by sucking their blood.

[0003] Rats also have sharp teeth, which can bite through electrical cords and communication cables, causing power outages, fires, communication disruptions, etc. Furthermore, rats can chew through food, furniture, electrical appliances, etc., causing economic damage.

[0004] As mentioned above, rats not only cause damage to property but can also cause damage to health, so rat repellents have been developed to prevent rats, who are the cause of this, from entering indoors. Patent Document 1 discloses an aerosol for rat and insect control containing peppermint oil and camphor oil. Patent Document 2 also discloses a rat repellent containing monoterpenes as an active ingredient. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 08-026924 [Patent Document 2] Japanese Patent Application Publication No. 03-181402 Summary of the Invention [Problem to be solved by the invention]

[0006] However, although the materials described in Patent Documents 1 and 2 are thought to be highly repellent to mice immediately after treatment, over time the mice may become accustomed to the smell and return to their original location.

[0007] The present disclosure has been made in consideration of these points, and its purpose is to provide an animal repellent and an animal repellent method that have a fast-acting repellent effect on animals and exhibit a highly sustained repellent effect without causing animals to become accustomed to the smell. [Means for solving the problem]

[0008] To achieve the above object, one aspect of the present disclosure can provide an animal repellent containing a phenol as an active ingredient. Other aspects of the present disclosure can include an animal repellent aerosol product in which an animal repellent containing a phenol as an active ingredient is contained in an aerosol container together with a propellant, an animal repellent device equipped with a carrier on which an animal repellent containing a phenol as an active ingredient is volatilized, or an animal repellent tablet containing an animal repellent containing a phenol as an active ingredient. Yet another aspect can also include an animal repellent method in which an animal repellent containing a phenol as an active ingredient is volatilized into the air.

[0009] The phenol may be, for example, one or more selected from guaiacol, 3-methoxyphenol, 4-ethylguaiacol, phenol, creosol, o-cresol, m-cresol, and p-cresol. The animal repellent may also be, for example, in a liquid form. [Effects of the Invention]

[0010] According to this embodiment, the repellent has a fast-acting effect on animals and uses phenols, the smell of which is difficult for animals to become accustomed to, as active ingredients, so that compared to conventional animal repellents, the repellent has a fast-acting effect and can maintain a high and sustained repellent effect without animals becoming accustomed to the smell.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0013] The animal repellent according to an embodiment of the present invention contains a phenol as an active ingredient that exerts a repellent effect on animals. Examples of phenols that can be used as the active ingredient include guaiacol (2-methoxyphenol), 3-methoxyphenol, 4-ethylguaiacol, phenol, creosol, o-cresol, m-cresol, and p-cresol. The active ingredient may be a single, arbitrarily selected phenol, or a mixture of two or more, arbitrarily selected phenols. The animal repellent may also contain other animal repellent ingredients in addition to the active ingredient.

[0014] Other animal repellent ingredients include, for example, essential oils and ingredients derived from essential oils. Of these, only one arbitrarily selected type may be contained as the active ingredient, or a mixture of two or more arbitrarily selected types may be contained as the active ingredient. In addition, a fragrance that reproduces the odor of natural enemies of animals, such as a cat odor fragrance, may be contained as the active ingredient.

[0015] Examples of the essential oils include peppermint oil, rosemary oil, lemongrass oil, lavender oil, orange oil, Ryukyu herb (shell ginger) oil, wasabi oil, pepper oil, mustard oil, etc. Only one of these may be arbitrarily selected as the active ingredient, or a mixture of two or more arbitrarily selected types may be arbitrarily selected as the active ingredient.

[0016] Examples of the essential oil-derived components include L-menthol, menthyl acetate, L-menthyl glyceryl ether, allyl isothiocyanate, allicin, gingerol, camphor, curcumin, piperine, citronellol, hexanal, hexyl acetate, geraniol, p-cymene, terpinene, terpineol, thymol, citronellal, geranyl formate, isoamyl formate, etc. Only one arbitrarily selected from these may be contained as an active ingredient, or a mixture of two or more arbitrarily selected types may be contained as an active ingredient.

[0017] Furthermore, the composition may contain, as an animal repellent component, for example, peppermint oil, camphor oil, monoterpenes, chili pepper extract, synthetic capsaicins, and the like.

[0018] The animal repellent may contain a solvent. Examples of usable solvents include alcohol solvents, hydrocarbon solvents, ester solvents, glycol solvents, fluorine-containing solvents, and water.

[0019] Examples of alcohols that can be used as solvents include ethanol, propanol, isopropanol, etc. Examples of hydrocarbon solvents that can be used as solvents include paraffin, isoparaffin, kerosene, etc. Examples of ester solvents that can be used as solvents include isopropyl myristate, etc. Examples of glycol solvents that can be used as solvents include propylene glycol monomethyl ether (PGME), etc. Examples of fluorine-based solvents that can be used as solvents include hydrofluoroolefins (HFOs), etc. Examples of water that can be used as solvents include tap water, ion-exchanged water, purified water, etc. Among these, only one arbitrarily selected type may be used as the solvent, or a mixture of two or more arbitrarily selected types may be used as the solvent. When water is used as the solvent, phenols do not dissolve as they are, so alcohols are added or the solvent is solubilized with a surfactant. Examples of usable surfactants include anionic surfactants, nonionic surfactants, amphoteric surfactants, etc. Among these, only one arbitrarily selected type may be used as the surfactant, or a mixture of two or more arbitrarily selected types may be used as the surfactant.

[0020] The animal repellent may contain other ingredients in addition to the solvent. Examples of other ingredients include insecticides, disinfectants and preservatives, deodorizers, pH adjusters, fragrances, colorants, repellent enhancers, UV absorbers, antioxidants, powders, and film-forming agents. Of these, the animal repellent may contain only one arbitrarily selected ingredient as the other ingredient, or may contain a mixture of two or more arbitrarily selected ingredients as the other ingredient.

[0021] The animal repellent containing the above-mentioned components can be in liquid form. In this case, the lower limit of the concentration of the active ingredient (mg / vol % of the total liquid) can be, for example, 1 or more, preferably 10 or more. The upper limit of the concentration of the active ingredient (mg / vol % of the total liquid) can be 50 or less, preferably 45 or less.

[0022] The lower limit of the amount of animal repellent to be treated is 3 mg / m of active ingredient. 3 A treatment amount of 20 mg / m or more is preferable. 3 The upper limit of the amount of the animal repellent to be treated is 60 mg / m of the active ingredient. 3 A treatment amount of 55 mg / m or less is preferred. 3 The processing amount can be set as follows.

[0023] Examples of animals that can be repelled by the animal repellent include small animals, such as house mice, brown rats, black rats, nutrias, weasels, and moles. The repellent effect is also exerted on other animals, such as dogs, cats, raccoons, palm civets, wild boars, and deer. Among these, the animal repellent exhibits a particularly high repellent effect on house mice, brown rats, and black rats.

[0024] Animal repellents can be used indoors or outdoors. Examples of places where they can be used include attics, ceilings, under floors, under eaves, storage sheds, warehouses, barns, closets, garages (parking lots, bicycle parking lots), entrances, kitchens, living rooms, bathrooms, toilets, bedrooms, gardens, garbage disposal areas, and holes in the walls of rooms and hallways. Animal repellents can also be used in gaps between electrical appliances such as refrigerators and walls, between electrical appliances and furniture, between furniture and walls, and between furniture and other pieces of furniture.

[0025] FIG. 1 shows an animal repellent aerosol product 1 according to an embodiment of the present invention. The animal repellent aerosol product 1 comprises an aerosol container 2 containing an animal repellent together with a propellant, a cap 3, a spray button 4, and a nozzle 5. The aerosol product 1 is used in an animal repellent method. Examples of propellants that can be used include liquefied petroleum gas (LPG), dimethyl ether (DME), and compressed gases (carbon dioxide, nitrogen, nitrous oxide). The propellant may contain only one arbitrarily selected type of propellant from among these, or a mixture of two or more arbitrarily selected types.

[0026] The aerosol container 2 is a pressure-resistant container, and is provided with a valve mechanism, a tip (not shown), and the like at its top. The valve mechanism is operable by the spray button 4, and is configured to continuously spray the contents of the aerosol container 2 while the spray button 4 is pressed. The valve mechanism may be a fixed-amount spray type, or may be configured as a fixed-amount spray valve mechanism that sprays a fixed amount of the contents of the aerosol container 2 and then stops when the spray button 4 is operated once. The fixed amount can be, for example, in the range of 0.1 mL to 3.0 mL. The aerosol container 2 may also be a total-amount spray type aerosol container, in which the entire amount of the contents of the aerosol container 2 is sprayed in one spray operation.

[0027] The cap 3 is a member attached to the top of the aerosol container 2. The nozzle 5 is integrated with the spray button 4 and is formed in a cylindrical or tubular shape to spray the contents from the aerosol container 2 via a valve mechanism. An outlet 5a opens at the tip of the nozzle 5. The structures and shapes of the aerosol container 2, cap 3, spray button 4, and nozzle 5 are examples, and structures and shapes other than those shown in the drawings can also be used. For example, the number of outlets 5a may be one, or two or more. When two or more outlets 5a are provided, the multiple outlets 5a may be arranged vertically or horizontally, or may be arranged in a matrix when viewed from the front.

[0028] The minimum inner diameter of the nozzle 5 is, for example, 0.4 mm or more, preferably 0.6 mm or more. The maximum inner diameter of the nozzle 5 is, for example, 1.2 mm or less, preferably 0.9 mm or less.

[0029] The lower limit of the ejection amount per second is, for example, 1 mL or more, preferably 4.0 mL or more, and the upper limit of the ejection amount per second is, for example, 10.0 mL or less, preferably 8.0 mL or less.

[0030] When the aerosol container 2 is a fixed-volume spray type, the lower limit of the amount sprayed per time is 0.1 mL or more, preferably 0.5 mL or more. When the aerosol container 2 is a fixed-volume spray type, the upper limit of the amount sprayed per time is 3.0 mL or less, preferably 2.0 mL or less.

[0031] The animal repellent may be sprayed from the aerosol container 2 once or multiple times. The animal repellent may be sprayed multiple times from the aerosol container 2 in one treatment, in which case the animal repellent may be sprayed intermittently at time intervals. The time intervals may be, for example, 10 hours or more, or 20 hours or more. The time intervals may also be 40 hours or less, or 50 hours or less. By repeatedly spraying the animal repellent at time intervals, animals such as rats learn that the active ingredient contained in the animal repellent has an unpleasant smell and that the propellant or solvent adhering to their bodies is unpleasant, thereby preventing the animals from settling in.

[0032] The average particle diameter (D50) of the animal repellent sprayed from the aerosol container 2 is set to be 35 μm or more at a point 50 cm away from the nozzle 5a in the spray direction. Also, the average particle diameter (D50) of the animal repellent sprayed from the aerosol container 2 is set to be 65 μm or less at a point 50 cm away from the nozzle 5a in the spray direction.

[0033] Here, we will explain the method for measuring the average particle size of the animal repellent sprayed from the aerosol container 2. Although not shown, the animal repellent is sprayed from a position where the distance between the laser beam irradiated onto the light receiving section by the laser light irradiating section of the particle size measuring device and the nozzle 50a is 50 cm, so that the animal repellent passes through the laser beam in a direction perpendicular to the direction of irradiation. Measurements are taken while the animal repellent is being sprayed, and the particle size distribution of the animal repellent is analyzed by an automatic processing device to determine the average particle size (D50). This method is well known. The measuring device used is an LDSA-SPR-1500A manufactured by Microtrac-Bell Corporation.

[0034] If the volume ratio of the animal repellent (concentrate) to the propellant (gas) contained in the aerosol container 2 is defined as the liquid-to-gas ratio (liquid / gas), the range of the liquid-to-gas ratio is 80 / 20 to 1 / 99, with a range of 70 / 30 to 1 / 99 being preferred.

[0035] When spraying the animal repellent from the aerosol container 2, it may be sprayed, for example, into space, or onto the floor or into a gap. The direction in which the animal repellent is sprayed may be upward, downward, or horizontal. It may also be sprayed upright or inverted. Furthermore, it may be sprayed while the aerosol container 2 is tilted diagonally or sideways.

[0036] When spraying the animal repellent indoors, the space size can be 40 tatami mats or less, and preferably 10 to 25 tatami mats. In this disclosure, 1 tatami mat is defined as 1.8 m 2 The size of the space is defined as 176m. 3 It can be less than 44m 3 More than 110m 3 The following is preferred: By using the animal repellent aerosol product 1, it is possible to carry out an animal repellent method in which an animal repellent having a phenol as an active ingredient is vaporized into the air.

[0037] By making the animal repellent liquid, it can be sprayed using a hand spray mechanism, a trigger spray mechanism, or the like, in addition to an aerosol. That is, when the animal repellent is contained in a container and the user operates a hand spray mechanism or a trigger spray mechanism attached to the container, the animal repellent can be sprayed over a wide area. This also makes it possible to implement an animal repellent method in which the animal repellent is volatilized into the air.

[0038] Alternatively, a liquid animal repellent can be stored in a container and sprayed from a spray nozzle attached to the container. The spray nozzle may be, for example, a shower nozzle having multiple outlets. The animal repellent may be sprayed using a sprayer equipped with a pump that pressurizes the container in which the animal repellent is stored. The animal repellent may also be sprayed using a sprayer equipped with an electric pump. The liquid animal repellent may also be made into a concentrated liquid. In the case of a concentrated liquid, it may be diluted with water and then sprayed or sprayed. The dilution ratio may be set as desired.

[0039] Although not shown, an animal repellent device that repels animals can also be constructed by using an animal repellent. The animal repellent device includes a carrier that volatilizes an animal repellent having a phenol as an active ingredient. By using the animal repellent device, it is possible to implement an animal repellent method in which the animal repellent having a phenol as an active ingredient is volatilized into the air. The animal repellent device may be installed, for example, indoors or outdoors.

[0040] The animal repellent device may be of a natural evaporation type, an air-blowing evaporation type, or a thermal evaporation type. The animal repellent device may include a container for housing a carrier. The container has a vent hole formed therein, and air flows in and out through the vent hole, causing the animal repellent held in the carrier to volatilize to the outside of the container. The carrier may be replaceable.

[0041] A natural evaporation type animal repellent device has a chemical solution containing an animal repellent supported on a carrier, and the animal repellent volatilizes over time from the carrier at room temperature. The animal repellent can be volatilized by natural air convection or natural wind. Examples of carriers for natural evaporation type animal repellent devices include solid carriers such as plastics, cellulose substrates, nonwoven fabrics, synthetic fibers, foam materials, and meshes. The carrier may be an impregnated body impregnated with the animal repellent. Multiple solid carriers can also be used in combination.

[0042] Furthermore, the medicinal liquid containing the animal repellent can be made into a gel, jelly, or paste using a gelling agent. In this case, the gelling agent serves as the carrier. Examples of gelling agents include water-absorbent resins (acrylic acid-based polymers), agar, pectin, and the like. Of these, only one arbitrarily selected type may be contained as the gelling agent, or a mixture of two or more arbitrarily selected types may be contained as the gelling agent. Furthermore, the animal repellent in gel, jelly, or paste form may be supported on a solid carrier, or may be applied to, for example, floors, walls, ceilings, the ground, etc.

[0043] An air-blowing transpiration type animal repellent device includes a carrier that is included in a natural transpiration type animal repellent device and a blower that blows air onto the carrier. The blower may be powered by electricity supplied from, for example, a primary battery or a secondary battery, or by electricity supplied from a commercial power source. The blower includes a motor and a fan that is driven to rotate by the motor. The rotating fan generates an airflow toward the carrier, causing the air to hit the carrier, and as a result, the animal repellent that volatilizes from the carrier is carried by the airflow and diffuses over a wide area.

[0044] The carrier may be placed in a container and the animal repellent device may be placed on the floor, for example, or may be hung from a hook, etc. The carrier may be in the form of a sheet, or may be made attachable with a pressure sensitive adhesive or glue.

[0045] A thermal evaporation type animal repellent device has a carrier that is included in a natural evaporation type animal repellent device and a heating unit that heats the carrier. The heating unit may be composed of, for example, an electric heater that generates heat when supplied with electricity. Heating the carrier to a temperature higher than room temperature using the heating unit improves the volatility of the animal repellent, allowing the animal repellent to volatilize over a wider area. The animal repellent can also be diffused into the air in the form of, for example, a fumigant, a smoke bomb, or the like. The animal repellent device may also be equipped with both the heating unit and the fan.

[0046] An animal repellent containing a phenol as an active ingredient can also be made into a powder or granules supported on a solid carrier such as silicon dioxide. By spraying the powder or granules, the animal repellent containing a phenol as an active ingredient can be volatilized into the air. By using the above powder or granules, an animal repellent method can be implemented in which the animal repellent containing a phenol as an active ingredient is volatilized into the air. The powder or granules can also be used by storing them in a container with a ventilation hole or a breathable bag.

[0047] Animal repellent tablets containing an animal repellent containing a phenol as an active ingredient can also be produced. Powders or granules containing the animal repellent supported on a solid carrier such as silicon dioxide can be formed into tablets using a pressure molding machine, tableting machine, or the like. The shape of the tablets is not particularly limited, and can be, for example, plate-like, columnar, cone-like, frustum-like, spherical, granular, or other shapes. The tablets thus obtained can also be used by scattering. Using the tablets enables the implementation of an animal repellent method in which an animal repellent containing a phenol as an active ingredient is vaporized into the air. The animal repellent tablets can also be used by being contained in a container with an air vent or a breathable bag. The powder or granules can also be used in combination with the animal repellent tablets. Air can be blown through the powder or granules using the above-mentioned air blower, or the powder or granules can be heated using the above-mentioned heating unit. [Example]

[0048] EXAMPLES The present invention will be explained in more detail below with reference to examples and comparative examples, but the present invention is not limited to these examples.

[0049] (Screening test for active ingredients in animal repellents) A screening test for the active ingredient of an animal repellent will be described. The temperature during the test was 25°C ± 2°C, and the humidity during the test was 40%. Examples 1 and 2 and Comparative Example 1 shown in Table 1 were prepared as test agents.

[0050] A 5-cm diameter filter paper was uniformly impregnated with 13 mg of each component from Examples 1 and 2 and placed in a petri dish. In Comparative Example 1, only the filter paper was placed in the petri dish. As shown in Figure 2, two plastic containers 60A and 60B were prepared. A hole was drilled in one side of each container 60A and 60B, and they were connected by a polyvinyl chloride pipe 61 to allow mice to move between them. One container 60A contained sawdust, a test agent, and food, and served as the treatment group. The other container 60B contained sawdust and an empty petri dish, and served as the untreated group. A single mouse was released into the untreated group, and each container 60A and 60B was covered with a metal mesh lid. The mouse's residence time in each container 60A and 60B over one hour was measured, and the repellency rate was calculated using the following formula (1). The total residence time of the mouse in the untreated group was designated T1, and the total residence time of the mouse in the treated group was designated T2.

[0051] Repellency rate (%) = (T1-T2) / T1 x 100

[0052] [Table 1]

[0053] As shown in Table 1, when guaiacol or 3-methoxyphenol is used as the active ingredient, the repellency rate is 70% or more, providing a high level of animal repellency. Furthermore, the same repellency effect as for house mice can be obtained for small animals such as brown rats, brown rats, nutria, weasels, and moles, as well as for animals such as dogs, cats, raccoons, palm civets, wild boars, and deer. Furthermore, similar repellency can be obtained even when a solvent is included.

[0054] (Animal spatial avoidance test 1) Next, we will explain the spatial avoidance test 1 for animals. The test location was an 8-tatami room (35 m 3) in a windless, constant temperature room. The temperature during the test was 25°C ± 2°C, and the humidity during the test was 40%. The test agents used were Example 3 and Comparative Examples 2 to 4 shown in Table 2. The test agents were prepared by dissolving each component in ethanol and filling an aerosol container with 0.40 LPG propellant. The liquid-to-gas ratio (liquid / gas) was 30 / 70. The aerosol container was equipped with a metered valve that dispensed 1.0 mL per spray.

[0055] As shown in Figure 3, five mice were placed in the treatment area of ​​a windless, temperature-controlled room and allowed to acclimate for four hours. Acclimation was performed by using a concrete block with a hole as a settlement source, and by putting water and food in the room with the door closed. The door to the treatment area was then opened 2 cm, and the test agent contained in an aerosol container was sprayed twice through the hole. The number of mice staying in the treatment area was counted immediately, and 3, 6, 16, and 24 hours later, and the repellency rate was calculated using the following formula (2). In the comparative example, the repellency was checked only after 16 hours.

[0056] Repellency rate (%) = Number of mice in the untreated area (mice) / Total number of mice (mice) × 100

[0057] [Table 2]

[0058] Guaiacol can provide a high level of animal repellency, and it is effective against small animals such as brown rats, brown rats, nutria, weasels, and moles, as well as dogs, cats, raccoons, palm civets, wild boars, and deer, similar to that of house mice.

[0059] (Reach distance test 1) Next, we will explain the reach test 1 of the animal repellent. The test location was the attic of a factory (semi-open space). The temperature during the test was 25°C ± 2°C, and the humidity during the test was 40%. The test agent was a solution of the active ingredient guaiacol in ethanol. This test agent was filled into an aerosol container together with 0.40 LPG propellant. The liquid-to-gas ratio (liquid / gas) was 50 / 50. The agent treatment amount of guaiacol (mg / m 3 ) were changed to give Examples 6 to 8.

[0060] As shown in Figure 4, eight mice were prepared, one in each of the commercially available mouse breeding cages 70. One mouse was placed 3 m away from the nozzle of the aerosol container in the direction of spraying, one at a distance of 5 m, three at a distance of 7 m, and three at a distance of 10 m. The three mice at the 7 m and 10 m positions were spaced 1 m apart in the horizontal direction perpendicular to the spraying direction. After acclimatizing the mice for 3 to 4 hours, the test agent was injected at a predetermined dose (1 s / m 2 After the test agent was sprayed, the presence or absence of alert behavior of the mice at each point was confirmed, and the response rate was calculated using the following formula (2).

[0061] <Checklist of vigilance actions> Walking hurriedly Busily digging through sawdust Stands upright and alert while moving whiskers Response rate (%) = Number of rats that showed alert behavior (no. of rats) / Total number of rats (no. of rats) × 100

[0062] [Table 3]

[0063] The guaiacol treatment dose was 23.7 mg / m 3By doing the above, it was found that the spray also stimulates alert behavior in house mice at a distance of 10 m. Furthermore, the spray also stimulates alert behavior in small animals such as brown rats, brown rats, nutrias, weasels, and moles, as well as dogs, cats, raccoons, palm civets, wild boars, and deer, similar to that of house mice.

[0064] (Reach distance test 2) Next, we will explain the animal repellent reach test 2. The test was conducted in the attic of a factory (a semi-open space). The temperature during the test was 25°C ± 2°C, and the humidity during the test was 40%. The active ingredient, guaiacol, was dissolved in a mixture of propylene glycol monomethyl ether (PGME) and isoparaffin, and the test compound was filled into an aerosol container together with a mixture of propellants, DME and LPG. The liquid / gas ratio (liquid / gas) was 40 / 60.

[0065] Each tip was attached to the nozzle hole of the aerosol container. The tips prepared were one with six holes of 0.9 mm diameter (Example 10), one with one hole of 1.0 mm diameter (Example 7), one with one hole of 1.6 mm diameter (Example 8), and one with one hole of 2.2 mm diameter (Example 9).

[0066] A total of nine mice were prepared by placing one mouse in each commercially available mouse breeding cage. Three mice were placed at a distance of 6 m, three at a distance of 8 m, and three at a distance of 10 m from the nozzle of the aerosol container in the direction of spraying. The three mice at the 6 m, 8 m, and 10 m positions were spaced 1 m apart in the horizontal direction perpendicular to the spraying direction. The rest of the experiment was the same as in Reach Test 1. Furthermore, the average particle diameter (D50) at a spraying distance of 50 cm was measured for each example.

[0067] [Table 4]

[0068] By setting the average particle size (D50) at 35 μm or more and 65 μm or less at a spray distance of 50 cm, a high animal repellent effect can be achieved. Furthermore, the same repellent effect can be achieved against small animals such as brown rats, brown rats, nutria, weasels, moles, as well as dogs, cats, raccoons, palm civets, wild boars, and deer as against house mice.

[0069] (Animal spatial avoidance test 2) Next, we will explain the spatial avoidance test for animals. The test location was an 8-tatami room (35 m 3 ) in a windless, constant temperature room. The temperature during the test was 25°C ± 2°C, and the humidity during the test was 40%. The test agent used was Example 5 shown in Table 5. As Comparative Example 5, a rat repellent aerosol agent containing natural peppermint oil, Ryukyu herb fragrance, and cat odor fragrance as active ingredients was used.

[0070] As shown in Figure 3, five mice were placed in the treatment area of ​​a windless, temperature-controlled room and allowed to acclimate for four hours. Acclimation was performed by using a concrete block with a hole in it as a settlement source, and by adding water and food with the door closed. The door to the treatment area was then opened 2 cm, and the test agent contained in an aerosol container was sprayed twice through the opening. The number of mice remaining in the treatment area was counted 3, 6, 16, and 24 hours later, and the repellency rate was calculated using the following formula (3):

[0071] Repellency rate (%) = Number of mice in the untreated area (mice) / Total number of mice (mice) × 100

[0072] [Table 5]

[0073] Even after 16 hours and 24 hours, Example 5 can achieve a higher animal repellent effect than Comparative Example 5. Furthermore, the same repellent effect as that for house mice can be achieved for small animals such as brown rats, brown rats, nutria, weasels, and moles, as well as for animals such as dogs, cats, raccoons, palm civets, wild boars, and deer.

[0074] (Repeated spatial avoidance test) Next, we will explain the repeated spatial avoidance test. The test location was an 8-tatami room (35 m 3 The temperature during the test was 25°C ± 2°C, and the humidity during the test was 40%. The test agents used were Example 5 and Comparative Example 5.

[0075] The experiment was carried out in the same manner as Animal Spatial Aversion Test 1. The second injection was carried out 30 hours after the first injection, the third injection was carried out 48 hours after the first injection, and the fourth injection was carried out 98 hours after the first injection.

[0076] [Table 6]

[0077] In both Example 8 and Comparative Example 5, the repellency rate dropped to 20% after 30 hours, but by spraying the product a second, third, and fourth time, Example 8 was able to maintain a high repellent effect for up to 128 hours. In this way, by using phenols as the active ingredient, a high and sustained repellent effect can be achieved without the animals becoming accustomed to the smell.

[0078] (Field Test) Next, the field test will be described. The test location was the attic of a chicken farm. The test agent was Example 10. Since there were four wild roof rats in a space approximately 1 m wide, 6 m deep, and 20 cm high, the test agent of Example 8 was sprayed. As a result, all of the roof rats quickly escaped out of the attic immediately after spraying.

[0079] The above-described embodiments are merely illustrative in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. For example, even if the solvent is replaced with another solvent, the same repellent effect as in Examples 1 to 10 can be achieved by using phenols as the active ingredient. Even when an animal repellent device, animal repellent tablet, powder, or granule is used, the same repellent effect as in Examples 1 to 10 can be achieved by using phenols as the active ingredient. [Industrial Applicability]

[0080] As described above, the present disclosure can be used to repel animals such as rats for a long period of time. [Explanation of symbols]
