Description

Technical Field

[0001] This disclosure relates to animal repellents, aerosol products for animal repellency, animal repellent devices, animal repellent tablets, and methods for animal repellency. Background Technology

[0002] As we all know, rats, as animals, can invade houses, buildings, and other structures, causing various problems. For example, when rats defecate and urinate indoors, these excrement remain, making the space not only dirty but also potentially causing unpleasant odors. Furthermore, rats can spread bacteria, sometimes leading to infectious diseases. Additionally, rats can sometimes be infested with mites and fleas, which can suck the blood of humans or pets, posing health risks.

[0003] In addition, rats possess sharp teeth, which they can use to gnaw through electrical wires and communication cables, causing power outages, fires, and communication failures. Furthermore, rats gnaw on food, furniture, and appliances, sometimes resulting in economic losses.

[0004] As mentioned above, rats not only damage property but sometimes also pose health risks. Therefore, to prevent these hazards—rat intrusions into indoor spaces—rat repellents have been developed. Patent Document 1 discloses a rodent- and insect-repellent aerosol containing peppermint oil and camphor oil. Patent Document 2 discloses a rat repellent with monoterpenes as its active ingredient.

[0005] Existing technical documents Patent documents Patent Document 1: Japanese Patent Application Publication No. 08-026924 Patent Document 2: Japanese Patent Application Publication No. 03-181402 Summary of the Invention

[0006] The technical problem that the invention aims to solve However, although the technical solutions of Patent Document 1 and Patent Document 2 show high repellency to mice immediately after treatment, over time, the mice sometimes become accustomed to the smell and return to their original location.

[0007] This disclosure was made to solve the above-mentioned technical problems, and its purpose is to provide an animal repellent and an animal repellent method that has a rapid repellent effect on animals, and animals do not become accustomed to its smell and exhibit a high and sustained repellent effect.

[0008] Technical solutions for solving technical problems To achieve the above objectives, one aspect of this disclosure is an animal repellent with phenols as the active ingredient. Other aspects of this disclosure include: an animal repellent aerosol product in which the animal repellent with phenols as the active ingredient is contained together with a propellant in an aerosol container; an animal repellent device comprising a carrier in which the animal repellent with phenols as the active ingredient is carried in a volatile manner; and an animal repellent tablet containing the animal repellent with phenols as the active ingredient. Furthermore, as another aspect, a method for dispersing the animal repellent with phenols as the active ingredient into the air is also possible.

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

[0010] The effects of the invention According to this aspect, since the active ingredient is phenol, which exhibits a rapid repellent effect on animals and whose odor is difficult for animals to become accustomed to, it has a rapid repellent effect compared to conventional animal repellents, and animals do not become accustomed to its odor, thus maintaining a high and sustained repellent effect.

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the following description of preferred embodiments is merely illustrative and is not intended to limit the invention, its application, or its uses.

[0016] The animal repellent according to embodiments of the present invention contains phenols, which are effective ingredients that repel animals. Examples of phenols that can be used as effective ingredients include: guaiacol (2-methoxyphenol), 3-methoxyphenol, 4-ethylguaiacol, phenol, cresol, o-cresol, m-cresol, p-cresol, etc. It may contain only one of these as an effective ingredient, or it may contain a mixture of two or more of these as an effective ingredient. In addition to the above-mentioned effective ingredients, the animal repellent may also contain other animal repellent components.

[0017] Other animal repellent ingredients include, for example, essential oils and components derived from essential oils. The active ingredient may be any one of these selected ingredients, or it may be a mixture of two or more selected ingredients. Additionally, it may include fragrances that reproduce the scent of predator animals, such as cat scent fragrances, as active ingredients.

[0018] Examples of essential oils mentioned above include: peppermint oil, rosemary oil, lemongrass oil, lavender oil, orange oil, Ryukyu herb (ginkgo) oil, wasabi oil, pepper oil, and mustard oil. An active ingredient may be any one of these selected ingredients, or it may be a mixture of two or more selected ingredients.

[0019] Examples of components derived from essential oils include: L-menthol, menthyl acetate, L-menthylglycerin ether, allyl isothiocyanate, allicin, gingerol, camphor, curcumin, piperine, citronellol, hexanal, hexyl acetate, geraniol, p-cymene, terpinene, terpineol, thymol, citronellol, geraniol formate, and isoamyl formate. The active ingredient may be any one of these selected components, or it may be a mixture of two or more selected components.

[0020] In addition, as an animal repellent ingredient, it may also contain peppermint oil, camphor oil, monoterpenes, capsicum extract, synthetic capsaicin, etc.

[0021] Animal repellents may also contain solvents. Examples of usable solvents include: alcohols, hydrocarbons, esters, diols, fluorinated solvents, and water.

[0022] Alcohols that can be used as solvents include ethanol, propanol, and isopropanol. Hydrocarbon solvents that can be used as solvents include paraffin wax, isoalkanes, and kerosene. Ester solvents that can be used as solvents include isopropyl myristate. Diol solvents that can be used as solvents include propylene glycol monomethyl ether (PGME). Fluorinated solvents that can be used as solvents include hydrofluoroolefins (HFO). Water that can be used as a solvent includes tap water, deionized water, and purified water. A solvent may be a mixture of any two or more of these substances. When water is used as a solvent, since phenols are not directly soluble in water, an alcohol or a surfactant is required to make them soluble. Examples of surfactants that can be used include anionic surfactants, nonionic surfactants, and amphoteric surfactants. A surfactant may be a mixture of any two or more of these substances.

[0023] Animal repellents may also contain other ingredients besides solvents. Examples of such other ingredients include: insecticides, bactericides / preservatives, deodorants, pH adjusters, fragrances, colorants, repellent efficacy enhancers, UV absorbers, antioxidants, powders, film-forming agents, etc. They may contain only one of these as other ingredients, or they may contain a mixture of two or more of these as other ingredients.

[0024] Animal repellents containing the above-mentioned ingredients can be in liquid form. In this case, the lower limit of the concentration of the active ingredient (mg / total liquid v%) can be set to, for example, 1 or more, preferably 10 or more. The upper limit of the concentration of the active ingredient (mg / total liquid v%) can be set to 50 or less, preferably 45 or less.

[0025] The lower limit of treatment dose for animal repellents can be set at 3 mg / m³ of the active ingredient. 3 The above processing volume is preferably set at 20 mg / m³ of active ingredient. 3 The above treatment dosage. The upper limit for the treatment dosage of animal repellents can be set at 60 mg / m³ of active ingredient. 3 The following treatment dosage is preferably set at 55 mg / m³ of active ingredient. 3 The following processing volume.

[0026] Animals targeted by animal repellents include small animals such as house mice, brown rats, roof rats, coypus, weasels, and moles. In addition, they also have a repellent effect on dogs, cats, raccoons, civets, wild boars, and deer. Among these, animal repellents are particularly effective against house mice, brown rats, and roof rats.

[0027] Animal repellents can be used both indoors and outdoors. Examples of suitable application areas include: attics, behind ceilings, under floors, under eaves, storage rooms, warehouses, barns, closets, garages (parking lots, bicycle parking areas), entryways, kitchens, living rooms / family rooms, bathrooms, toilets, bedrooms, patios, garbage disposal areas, and holes made in walls in living rooms or hallways. Additionally, animal repellents can be used in gaps between appliances such as refrigerators and walls, between appliances and furniture, between furniture and walls, and between pieces of furniture.

[0028] Figure 1 This illustration shows an animal repellent aerosol product 1 according to an embodiment of the present invention. The animal repellent aerosol product 1 includes an aerosol container 2, a cap 3, a spray button 4, and a nozzle 5. The animal repellent and the propellant are contained together as contents in the aerosol container 2. The aerosol product 1 is an aerosol product used in animal repellent methods. Examples of usable propellants include liquefied petroleum gas (LPG), dimethyl ether (DME), and compressed gases (carbon dioxide, nitrogen, nitrous oxide). It may contain only one of these as a propellant, or it may contain a mixture of two or more of these as a propellant.

[0029] The aerosol container 2 is a pressure-resistant container with a valve mechanism and a nozzle (not shown) on its upper part. The valve mechanism is configured to be operated by the spray button 4, continuously spraying the contents of the aerosol container 2 while the spray button 4 is pressed. The valve mechanism can be a metered-dispensing type, where a certain amount of the contents of the aerosol container 2 is sprayed out with each operation of the spray button 4, and then stops. This certain amount can be, for example, set in the range of 0.1 mL to 3.0 mL. Alternatively, the aerosol container 2 can be a full-volume spray type, where all the contents of the aerosol container 2 are sprayed out in a single spray operation.

[0030] The cap 3 is a component installed on the upper part of the aerosol container 2. The nozzle 5 is integrated with the spray button 4, and the nozzle 5 is formed into a cylindrical or tubular shape to spray the contents of the aerosol container 2 via the valve mechanism. A spray port 5a is provided at the top of the nozzle 5. The structure and shape of the aerosol container 2, cap 3, spray button 4, and nozzle 5 are only one example, and structures and shapes other than those shown in the figure can also be used. For example, the number of spray ports 5a can be one or more. When there are two or more spray ports 5a, they can be arranged vertically, horizontally, or in a matrix shape in the front view.

[0031] 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.

[0032] The lower limit of the injection volume per second is set to 1 mL or more, preferably 4.0 mL or more. The upper limit of the injection volume per second is set to 10.0 mL or less, preferably 8.0 mL or less.

[0033] When the aerosol container 2 is a metered spray type, the lower limit of the spray volume per spray is set to 0.1 mL or more, preferably 0.5 mL or more. When the aerosol container 2 is a metered spray type, the upper limit of the spray volume per spray is set to 3.0 mL or less, preferably 2.0 mL or less.

[0034] The animal repellent can be sprayed from the aerosol container 2 either once or multiple times. It is also possible to spray the animal repellent from the aerosol container 2 multiple times in a single treatment. In this case, the animal repellent can be sprayed intermittently at set time intervals. For example, the time interval can be set to 10 hours or more, or 20 hours or more. Alternatively, the aforementioned time interval can be set to 40 hours or less, or 50 hours or less. By repeatedly spraying the animal repellent at set time intervals, animals such as mice will learn that the active ingredient in the animal repellent has an unpleasant odor, and that the propellant and solvent adhering to their bodies are uncomfortable, thereby preventing the animals from settling there.

[0035] The average particle size (D50) of the animal repellent sprayed from the aerosol container 2 is set to be 35 μm or more at a distance of 50 cm from the spray nozzle 5a along the spray direction. In addition, the average particle size (D50) of the animal repellent sprayed from the aerosol container 2 is set to be 65 μm or less at a distance of 50 cm from the spray nozzle 5a along the spray direction.

[0036] Here, a method for measuring the average particle size of the animal repellent sprayed from aerosol container 2 is described. The animal repellent is sprayed through the laser beam (not shown) in a direction orthogonal to the irradiation direction by a laser beam irradiation unit of a particle size measuring machine illuminating the receiving part. The distance between the laser beam and the spray nozzle 50a is 50 cm. Measurements are performed during the spraying process, and the particle size distribution of the animal repellent is analyzed using an automatic processing unit to determine the average particle size (D50). This method is well-known. The measuring equipment is an LDSA-SPR-1500A manufactured by Microtrac BEL Co., Ltd.

[0037] When the volume ratio of the animal repellent (liquid) to the propellant (gas) contained in the aerosol container 2 is defined as the liquid-gas ratio (liquid / gas), the range of the liquid-gas ratio is set to 80 / 20 to 1 / 99, preferably in the range of 70 / 30 to 1 / 99.

[0038] When spraying animal repellent from aerosol container 2, it can be sprayed into space, towards the ground, or into a gap. The spray direction can be upward, downward, or horizontal. Furthermore, it can be sprayed upright or upside down. Additionally, it can be sprayed with the aerosol container 2 tilted or completely horizontal.

[0039] When using animal repellent spray indoors, the area of ​​the space can be set to 40 tatami mats or less, preferably 10 to 25 tatami mats. It should be noted that in this disclosure, one tatami mat is defined as 1.8m². 2 Additionally, the size of the space can be set, for example, to 176m. 3 The following is preferred: 44m 3 Above and 110m 3 The following describes an animal repellent method that, by using animal repellent aerosol product 1, disperses an animal repellent containing phenols as its active ingredient into the air.

[0040] By making the animal repellent into a liquid state, it can be sprayed using methods such as handheld sprayers and trigger sprayers, in addition to aerosols. That is, when the animal repellent is stored in a container, the user can spray the animal repellent in a mist over a wide area by operating a handheld sprayer or trigger sprayer mounted on the container. This also allows for animal repellency methods that disperse the animal repellent into the air.

[0041] Alternatively, liquid animal repellent can be contained in a container and sprayed from a nozzle mounted on the container. The spray nozzle can be, for example, a shower-type nozzle with multiple nozzle outlets. A sprayer equipped with a pump that pressurizes the container containing the animal repellent can also be used to spray it. Alternatively, a sprayer equipped with an electric pump can be used to spray the animal repellent. Furthermore, the liquid animal repellent can be prepared as a concentrated solution. In the case of a concentrated solution, it can be diluted with water before spraying or misting. The dilution ratio can be set arbitrarily.

[0042] Although not illustrated, an animal repellent device can be constructed using an animal repellent. The animal repellent device includes a carrier on which an animal repellent containing phenols as the active ingredient is carried in a volatile manner. By using the animal repellent device, an animal repelling method can be performed that disperses the phenol-based animal repellent into the air. The animal repellent device can be installed in either indoor or outdoor locations.

[0043] Animal repellent devices can be of the natural evaporation type, the air-assisted evaporation type, or the heated evaporation type. Animal repellent devices may also include a container for holding the repellent. A vent is formed in the container, through which air enters and exits, thereby dissipating the animal repellent held in the carrier to the outside of the container. The carrier may also be replaceable.

[0044] Naturally evaporating animal repellent devices consist of a liquid containing an animal repellent placed on a carrier. The repellent evaporates from the carrier over time at room temperature. Natural air convection and wind can be used to disperse the repellent. Examples of solid carriers for naturally evaporating animal repellent devices include: plastics, cellulose substrates, non-woven fabrics, synthetic fibers, foam materials, and mesh. The carrier can also be an impregnated body containing the animal repellent. Multiple solid carriers can also be used in combination.

[0045] Alternatively, a gelling agent can be used to make the liquid containing animal repellent into a gel, jelly, or paste form. In this case, the gelling agent becomes the aforementioned carrier. Examples of gelling agents include: water-absorbing resins (acrylic polymers), agar, pectin, etc. It can include only one of these as a gelling agent, or it can include a mixture of two or more of these as a gelling agent. Furthermore, the animal repellent in gel, jelly, or paste form can be carried on a solid carrier, or it can be applied to surfaces such as floors, walls, ceilings, and ground.

[0046] An air-assisted evaporative animal repellent device includes a carrier and a blower that blows air onto the carrier, as included in a naturally evaporating animal repellent device. The blower can operate using power supplied from, for example, a primary or secondary battery, or it can operate using power supplied from a commercial power source. The blower has an electric motor and a fan driven by the electric motor. By utilizing the rotating fan to generate an airflow toward the carrier, the air comes into contact with the carrier, resulting in the animal repellent evaporating from the carrier being widely dispersed with the airflow.

[0047] With the aforementioned carrier placed in the container, the animal deterrent device can be placed on the ground or, for example, attached to the container via hooks to suspend it. The carrier can be in sheet form or can be attached using adhesives or bonding agents.

[0048] The heated evaporation type animal repellent device includes a carrier and a heating element, which are present in the naturally evaporating type animal repellent device. The heating element can be, for example, an electric heater that generates heat through an electric supply. By heating the carrier to a temperature above room temperature using the heating element, the volatility of the animal repellent is increased, allowing it to disperse over a wider area. Furthermore, the animal repellent can be dispersed into the air in forms such as fumigants, fumigants, or smoke generators. An animal repellent device can also be configured to include both the heating element and the blower described above.

[0049] It can also be formulated as powder or granules, in which an animal repellent containing phenols as the active ingredient is carried on a solid carrier such as silica. By spraying the powder or granules, the animal repellent containing phenols as the active ingredient can be dispersed into the air. By using the above-mentioned powder or granules, an animal repellent method can be performed to disperse the animal repellent containing phenols as the active ingredient into the air. The powder or granules can also be stored in a container with a vent or a breathable bag for use.

[0050] It can also be formulated into animal repellent tablets containing an animal repellent with phenols as the active ingredient. A compression molding machine, tablet press, or similar device can be used to form tablets from powders or granules that carry the animal repellent on a solid carrier such as silica. The shape of the tablets is not particularly limited; for example, they can be formed into plates, columns, cones, frustums, spheres, granules, etc. The tablets obtained in this way can also be sprayed for use. By using the above-mentioned tablets, an animal repellent method can be performed that disperses the animal repellent with phenols as the active ingredient into the air. The animal repellent tablets can also be stored in containers with vents or breathable bags. Powders or granules can also be combined with animal repellent tablets for use. Air can be supplied to the powders or granules using the aforementioned blower, or the powders or granules can be heated using the aforementioned heating element.

[0051] [Example] The present invention will be described in more detail below through embodiments and comparative examples, but the present invention is not limited to these embodiments.

[0052] (Screening test of the active ingredient in animal repellents) The screening test for the active ingredient of the animal repellent is described. The temperature during the test was 25℃±2℃, and the humidity was 40%. As test reagents, Examples 1-2 and Comparative Example 1 shown in Table 1 were prepared.

[0053] 13 mg of each component from Examples 1 and 2 was evenly impregnated onto filter paper with a diameter of 5 cm, and then placed in a petri dish. In Comparative Example 1, only the filter paper was placed in the petri dish. Figure 2 As shown, two plastic containers 60A and 60B are prepared. A hole is formed on one side of each container 60A and 60B, and they are connected by a vinyl chloride pipe 61 to allow the mouse to move. Sawdust, test reagent, and bait are placed in one container 60A as the treatment area. Sawdust and an empty petri dish are placed in the other container 60B as the untreated area. One house mouse is placed in the untreated area, and each container 60A and 60B is covered with a metal mesh. The time the house mouse spends in each container 60A and 60B is measured over one hour, and the repulsion rate is calculated using the following formula (1). The total time the house mouse spends in the untreated area is set as T1, and the total time the house mouse spends in the treated area is set as T2.

[0054] Avoidance rate (%) = (T1 - T2) / T1 × 100 [Table 1]

[0055] As shown in Table 1, when guaiacol and 3-methoxyphenol are used as active ingredients, the repellency rate reaches over 70%, thus achieving a high repellency effect on animals. It should be noted that the same repellency effect as for house mice is achieved for small animals such as brown rats, roof rats, coypus, weasels, and moles, as well as dogs, cats, raccoons, civets, wild boars, and deer. Furthermore, the same repellency effect is achieved even when solvents are included.

[0056] (Animal spatial avoidance experiment 1) Next, the spatial avoidance experiment 1 for animals will be described. The experimental site was 8 tatami mats (35m²). 3 The test was conducted in a windless, constant-temperature room. The temperature during the test was 25℃±2℃, and the humidity was 40%. Examples 3 and Comparative Examples 2-4, as shown in Table 2, were used as test reagents. Each component was dissolved in ethanol and then filled into an aerosol container along with 0.40 LPG propellant. The liquid-to-gas ratio (liquid / gas) was set to 30 / 70. The aerosol container was equipped with a metering valve that dispensed 1.0 mL per spray.

[0057] like Figure 3 As shown, five house mice were placed in the treatment area of ​​a windless, constant-temperature room and allowed to acclimatize for 4 hours. A perforated concrete block was used as a fixed reference, and water and bait were placed inside with the entrance and exit sealed to allow for acclimatization. Then, the door of the treatment area was opened by 2 cm, and the test agent stored in an aerosol container was sprayed twice from this point. The number of house mice remaining in the treatment area was counted immediately after spraying, 3 hours later, 6 hours later, 16 hours later, and 24 hours later, and the repellency rate was calculated using the following formula (2). It should be noted that in the comparative example, the repellency rate was only confirmed after 16 hours.

[0058] Repellency rate (%) = Number of rats in the untreated area (number of rats) / Total number of rats (number of rats) × 100 [Table 2]

[0059] Guaiacin has a high repellent effect on animals. It should be noted that it also has the same repellent effect on small animals such as brown rats, roof rats, coypus, weasels, and moles, as well as dogs, cats, raccoons, civets, wild boars, and deer as it does on house mice.

[0060] (Distance Test 1) Next, the arrival distance test 1 for the animal repellent will be described. The test location was the attic (semi-open space) of the factory. The temperature during the test was 25℃±2℃, and the humidity was 40%. The test reagent was obtained by dissolving guaiacol, the active ingredient, in ethanol. This test reagent was filled into an aerosol container together with 0.40 LPG propellant. The liquid-to-gas ratio (liquid / gas) was set to 50 / 50. The dosage of guaiacol (mg / m³) was varied. 3 They are used as Examples 6 to 8.

[0061] like Figure 4 As shown, one house mouse was placed in each commercially available mouse cage 70, for a total of eight house mice. One mouse was positioned 3m away from the nozzle of the aerosol container along the spray direction, one mouse was positioned 5m away, three mice were positioned 7m away, and three mice were positioned 10m away. It should be noted that the three mice at the 7m and 10m positions were spaced 1m apart from each other in a horizontal direction perpendicular to the spray direction. After the mice were acclimatized for 3–4 hours, the test agent was sprayed at a specified rate (1 second / m²). 2 ). Confirm whether the mice at each location exhibited alarm behavior after the test agent was sprayed, and calculate the response rate as shown in the following formula (3).

[0062] <Items for confirming vigilant behavior> Walking anxiously anxiously digging sawdust He twitched his beard, remained alert, and stood up straight. Response rate (%) = Number of mice exhibiting alarm behavior (mice) / Total number of mice (mice) × 100 [Table 3]

[0063] It can be seen that the dosage of guaiacol was 23.7 mg / m³. 3 The above also indicated that house mice at a spray distance of 10 meters exhibited alert behavior. It should be noted that the same alert behavior was also induced in small animals such as brown rats, roof rats, coypus, weasels, moles, dogs, cats, raccoons, civets, wild boars, and deer.

[0064] (Distance test 2) Next, the arrival distance test 2 for the animal repellent will be described. The test location was the attic (semi-open space) of the factory. The temperature during the test was 25℃±2℃, and the humidity was 40%. As the test reagent, guaiacol, the active ingredient, was dissolved in a mixture of propylene glycol monomethyl ether (PGME) and isoalkanes, and this solution was then filled into an aerosol container along with a mixture of propellants DME and LPG. The liquid-to-gas ratio (liquid / gas) was set to 40 / 60.

[0065] Each nozzle was installed on the nozzle orifice of the aerosol container. As nozzles, a nozzle with six holes of 0.9 mm in diameter (Example 10), a nozzle with one hole of 1.0 mm in diameter (Example 7), a nozzle with one hole of 1.6 mm in diameter (Example 8), and a nozzle with one hole of 2.2 mm in diameter (Example 9) were prepared.

[0066] Nine house mice were prepared, with one mouse placed in each commercially available mouse cage. Three mice were positioned 6m away from the aerosol nozzle along the spray direction, three at 8m away, and three at 10m away. It should be noted that the three mice at 6m, 8m, and 10m were spaced 1m apart from each other in a horizontal direction orthogonal to the spray direction. Otherwise, the procedure was the same as in the distance test 1. Additionally, the average particle size (D50) at a spray distance of 50cm was measured in each embodiment.

[0067] [Table 4]

[0068] A high animal repellency effect can be achieved by ensuring that the average particle size (D50) at a spray distance of 50 cm is between 35 μm and 65 μm. It should be noted that the same repellency effect as for house mice can be achieved for small animals such as brown rats, roof rats, coypus, weasels, and moles, as well as dogs, cats, raccoons, civets, wild boars, and deer.

[0069] (Animal spatial avoidance experiment 2) Next, the spatial avoidance test for animals will be described. The test site was 8 tatami mats (35m²). 3 The test was conducted in a windless, constant-temperature room. The temperature during the test was 25℃±2℃, and the humidity was 40%. Example 5, shown in Table 5, was used as the test agent. Comparative Example 5 used a rat repellent aerosol containing natural peppermint oil, Ryukyu herbal spices, and cat scented fragrance as active ingredients.

[0070] like Figure 3As shown, five house mice were placed in the treatment area of ​​a windless, constant-temperature room and allowed to acclimatize for 4 hours. A perforated concrete block was used as a fixed reference, and water and bait were placed in the block with the entrance and exit sealed to allow for acclimatization. Then, the door of the treatment area was opened by 2 cm, and the test agent stored in the aerosol container was sprayed twice from that point. The number of house mice remaining in the treatment area was counted after 3 hours, 6 hours, 16 hours, and 24 hours, and the repellency rate was calculated using the following formula (4).

[0071] Repellency rate (%) = Number of rats in the untreated area (number of rats) / Total number of rats (number of rats) × 100 [Table 5]

[0072] Compared to Comparative Example 5, Example 5 also achieved a high animal repellency effect even after 16 hours and 24 hours. It should be noted that the same repellency effect as that for small animals such as brown rats, roof rats, coypus, weasels, and moles, as well as dogs, cats, raccoons, civets, wild boars, and deer, can be achieved.

[0073] (Repeated space avoidance test) Next, the repeated space avoidance test will be explained. The test site was 8 tatami mats (35m²). 3 The test was conducted in a windless, constant-temperature room. The temperature during the test was 25℃±2℃, and the humidity was 40%. Example 5 and Comparative Example 5 were used as test reagents.

[0074] The same method as in the animal spatial avoidance experiment 1 was used. It should be noted that a second spray was performed 30 hours after the first spray, a third spray was performed 48 hours after the first spray, and a fourth spray was performed 98 hours after the first spray.

[0075] [Table 6]

[0076] Both Example 8 and Comparative Example 5 showed a repellency rate decrease to 20% after 30 hours, but by performing a second, third, and fourth spray, Example 8 was able to maintain a high repellency effect until 128 hours later. In this way, by using phenols as the active ingredient, animals do not become accustomed to the odor, and a high and sustained repellency effect can be achieved.

[0077] (Field test) Next, the field experiment will be described. The test site was the attic of a chicken farm. The test agent was from Example 10. Four wild roof rats were present in a space approximately 1m wide, 6m deep, and 20cm high; therefore, the test agent from Example 8 was sprayed. As a result, all the roof rats quickly fled out of the attic immediately after spraying.

[0078] The above embodiments are merely illustrative in all respects and should not be construed as limiting. Furthermore, variations and modifications falling within the scope of the claims are also within the scope of this invention.
