Technical Field

The present invention relates to a pest repellent and a pest repellent product for repelling solenopsis invicta (Japanese: ヒアリ (Lebens)) and/or solenopsis tropica (Japanese: カミアリ (Lebens)).

Background

In recent years, pests designated as specific foreign organisms have been found in japan and become a significant social problem. As such specific foreign organisms, red imported fire ants and tropical imported fire ants are known, for example (hereinafter, collectively referred to as "specific foreign ants", however, in the present invention, argentina ants are not included in the specific foreign ants). The specific exotic ants are different from local ants, and have strong toxicity or high fertility. Therefore, when specific foreign ants are found, it is natural to completely repel them, but it is important that repelling measures be taken to prevent specific foreign ants from invading human living areas, which becomes an urgent need.

Conventionally, as an agent for repelling ants, for example, a repellent containing a natural essential oil as an active ingredient has been known (for example, see patent document 1). Patent document 1 describes, as active ingredients of ants repellents, oak moss, neroli oil (japanese: オレンジフラワー oil), sandalwood oil, spearmint oil, thyme white oil, patchouli oil, palmarosa oil, lemongrass oil, bay oil, garlic oil, rhinoceros oil, coconut oil, cinnamon leaf oil, dill seed oil (dill oil), thyme red oil, tolu oil, birch oil, and peru balsam.

Further, a method of controlling ants using a chemical such as mosquito repellent amine has been conventionally performed (for example, see patent document 2). While mosquito repellent amines are generally used as repellent ingredients for dipteran pests such as mosquitoes, according to patent document 2, hymenopteran pests such as ants are also cited as one of the target pests to be controlled.

Disclosure of Invention

Problems to be solved by the invention

However, specific foreign ants are ecologically very different from general local ants. Local ants, in addition to being underground, form colonies (nests) within the deadwood and carry out life activities in a relatively small number of familial units. On the other hand, specific exotic ants form colonies deep underground, and two kinds of ecology are known: in a community, there are a single queen que. Especially, the specific external ants with multiple queen-made ecology have higher fecundity when the number of the ants in the community is larger, and 4000 thousands of ants in one community can perform life activities.

As described above, since specific foreign ants are greatly different from local ants in terms of the scale of activity and the behavioral pattern, even when a repellent (active ingredient: natural essential oil) of ants described in patent document 1 or a control agent (active ingredient: mosquito repellent amine) described in patent document 2, which has been conventionally used, is applied to the colony of the specific foreign ants, the specific foreign ants cannot be completely repelled or repelled, and not only is there a possibility that some of the ants are quickly detected after emergence of the repellent or control agent, but also they are separated from the colony in order to evade the repellent effect or control effect thereof.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a pest repellent and a pest repellent product which can effectively provide a repellent effect on a specific foreign ant.

Means for solving the problems

The pest repellent of the present invention for solving the above problems is characterized in that,

the repellent composition for solenopsis invicta and/or solenopsis tropica comprises a piperidine derivative represented by the following formula (I).

[ solution 1]

R: C2-C6 alkyl or alkoxy

According to the pest repellent of the present configuration, although the piperidine derivative represented by the above formula (I) has been known to exhibit a repellent effect against pests such as mosquitoes, gnats, butterfly flies, house flies, stable flies, cockroaches and the like, it is judged that the piperidine derivative can be an active ingredient (repellent ingredient) for repelling solenopsis invicta and/or tropical imported ants based on a new finding that the piperidine derivative exhibits an excellent repellent effect against specific foreign ants such as solenopsis invicta and tropical imported ants. Accordingly, the pest repellent containing the piperidine derivative of the present configuration is useful as a pest repellent for solenopsis invicta and/or solenopsis tropica, and when the pest repellent of the present configuration is used, damage caused by solenopsis invicta and/or solenopsis tropica can be reduced.

In the pest repellent of the present invention,

in the formula (I), R is preferably an alkoxy group having 2 to 6 carbon atoms.

According to the pest repellent of the present configuration, the alkoxy group having 2 to 6 carbon atoms is selected as the substituent R in the piperidine derivative represented by the formula (I), and thereby the pest repellent having a more excellent repellent effect against solenopsis invicta and/or solenopsis tropica can be provided.

In the pest repellent of the present invention,

the above R is preferably 1-methylpropyloxy.

According to the pest repellent of the present configuration, by selecting 1-methylpropyloxy as the substituent R in the piperidine derivative represented by the above formula (I), the piperidine derivative can be used as an epothilone having a high pest repellent effect and excellent safety to the human body, and can be a pest repellent having a more excellent repellent effect against red imported fire ants and/or tropical fire ants.

In the pest repellent of the present invention,

preferably further comprises at least one of the following (a) and (b) as a repellent fragrance component,

(a) c8-16 hydrocarbon aldehydes and/or ketones

(b) Monoterpene alcohols and/or aromatic alcohols having 8 to 12 carbon atoms in total.

According to the pest repellent of the present configuration, by further containing a repellent fragrance component of at least one of the above (a) and (b) in addition to the piperidine derivative represented by the above formula (I), it is possible to strongly repel solenopsis invicta and/or solenopsis tropica by utilizing the synergistic effect of the piperidine derivative and the repellent fragrance component. In addition, since the piperidine derivative is non-fragrant, when a repellent fragrance component is combined, the original fragrance of the repellent fragrance component is hardly affected at all. Accordingly, the piperidine derivative is a repellent component having good compatibility with a repellent fragrance component.

In the pest repellent of the present invention, it is preferable that,

the repellent fragrance component of the above (a) is at least one selected from the group consisting of decanal, undecanal, dodecanal, 2-methylundecanal, tridecanal, 10-undecenal, citronellal, citral, neral, phenylacetaldehyde, cinnamaldehyde, α -pentylcinnamaldehyde, α -hexylcinnamaldehyde, convallal, perillaldehyde, 3, 5-dimethyl-3-cyclohexene-1-formaldehyde (Japanese: トリベルタール), cuminaldehyde, piperonal, tridecanone, l-carvone, menthone, pulegone, cis-jasmone, dihydrojasmone, α -damascenone, β -damascenone, α -irisone, β -ionone, 2-pentylcyclopentanone, 2-hexylcyclopentanone, 2-heptylcyclopentanone, methylbenzylketone, and methylphenylketone,

the repellent fragrance component of the above (b) is at least one selected from the group consisting of linalool, dehydrolinalool, dihydromyrcenol, geraniol, nerol, citronellol, menthol, terpineol, terpinen-4-ol, isopulegol, borneol, 1-phenylethyl alcohol, 2-phenylethyl alcohol, cinnamyl alcohol, thymol and eugenol.

According to the pest repellent of the present configuration, by selecting the repellent perfume component of the above (a) and the repellent perfume component of the above (b) from the above options, it is possible to provide a pest repellent capable of more strongly repelling solenopsis invicta and/or solenopsis tropicalis.

In the pest repellent of the present invention,

preferably, the repellent fragrance component (a) and the repellent fragrance component (b) are contained in a blending ratio (weight ratio) of 0.1/1 to 9/1.

According to the pest repellent of the present configuration, by containing the repellent fragrance component of the above (a) and the repellent fragrance component of the above (b) in the above blending ratio (weight ratio), a repellent effect (synergistic effect) enhanced by the different kinds of repellent fragrance components is obtained, and a pest repellent that is pleasant even with fragrance can be obtained.

In the pest repellent of the present invention,

it is preferable that the repellent further contains a glycol and/or a glycol ether as a repellent effect sustaining component.

In the pest repellent of the present invention, the glycols and/or glycol ethers have a higher vapor pressure than the piperidine derivative, and therefore the glycols and/or glycol ethers suppress excessive volatilization of the piperidine derivative. As a result, the repellent effect against solenopsis invicta and/or solenopsis tropica based on the piperidine derivative is sustained for a long period of time.

In the pest repellent of the present invention,

preferably, the composition contains substantially no insecticidal component.

According to the pest repellent of the present configuration, even if the pest repellent does not substantially contain an insecticidal component, a repellent effect against solenopsis invicta and/or solenopsis tropica can be obtained by the piperidine derivative represented by the above formula (I). Therefore, it is possible to make a pest repellent less resistant to daily use even for consumers allergic to the pesticidal component. Further, when the pests have become resistant to conventional repellent ingredients such as mosquito repellent amine, a repellent effect is also expected.

The pest repellent product of the present invention for solving the above problems is characterized in that,

the insect repellent is in the form of a liquid preparation, a gel preparation or a solid preparation containing any of the above insect repellents.

The pest-repellent product of the present invention contains the pest repellent of the present invention, and therefore is a practical and useful pest-repellent product for repelling solenopsis invicta and/or solenopsis tropica. Further, in the form of a product, a liquid preparation, a gel preparation, or a solid preparation is used, whereby an insect repellent product which is easy to use can be obtained.

Detailed Description

In the present invention, the present inventors have made extensive studies with respect to piperidine derivatives which have been known to exhibit a repellent effect against pests such as mosquitoes, gnats, butterfly flies, house flies, stable flies and cockroaches, and as a result, have found that these piperidine derivatives are unexpectedly superior in a repellent effect against specific exotic ants such as red fire ants and tropical fire ants which are now a problem in the society, and as a result, have finally completed pest repellents and pest repellent products against red fire ants and/or tropical fire ants. Hereinafter, the pest repellent and the pest repellent product of the present invention will be described. However, the present invention is not intended to be limited to the configurations of the following embodiments or the contents of the examples.

[ Pest repellents ]

The pest repellent of the present invention contains a piperidine derivative represented by the following formula (I) as a repellent ingredient for solenopsis invicta and/or solenopsis tropica.

[ solution 2]

R: C2-C6 alkyl or alkoxy

In the formula (I), R of the substituent is an alkyl group or an alkoxy group having 2 to 6 carbon atoms, but is preferably an alkoxy group having 2 to 6 carbon atoms.

When R is an alkyl group having 2 to 6 carbon atoms, the following are listed: ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, pentyl, hexyl and the like. When R is an alkoxy group having 2 to 6 carbon atoms, the following are mentioned: ethoxy, n-propoxy, isopropoxy, n-butoxy, tert-butoxy, 1-methylpropoxy, 2-methylpropoxy and the like. Among these substituents R, the most preferable is 1-methylpropyloxy group in which R is alkoxy group having 4 carbon atoms, which is 1-methylpropyl 2- (2-hydroxyethyl) -1-piperidinecarboxylic acid ester represented by the following formula (II) [ alternative name: alcaprevin ].

[ solution 3]

The piperidine derivative represented by the above formula (I) has a slightly lower vapor pressure as an insect repellent component than that of conventionally, i.e., commonly used mosquito repellent amines. For example, the vapor pressure of the Escarlatine represented by the above formula (II) as a representative piperidine derivative is 0.059Pa (25 ℃ C.), and the vapor pressure of the mosquito repellent amine is 0.23Pa (25 ℃ C.). Nevertheless, as shown by the results of the examples described later, the pest repellent of the present invention containing a piperidine derivative exhibits an excellent repellent effect against specific exotic ants such as solenopsis invicta or solenopsis tropica. On the other hand, the conventional pest repellent containing the culicifumide has a remarkably deteriorated repellent effect on specific foreign ants, as compared with the pest repellent of the present invention containing the piperidine derivative. This is presumably because: the piperidine derivative has a greater repellent effect than a spatial repellent effect caused by volatilization of an active ingredient (repellent ingredient) against contact with an insect pest by the active ingredient.

In addition, the pest repellent of the present invention may exhibit practically problem-free repellent effects on specific foreign ants by containing only piperidine derivatives as an effective ingredient, but in the case of compensating for contact repellent effects by spatial repellent effects, it is possible to more strongly repel specific foreign ants by synergistic effects. Therefore, in the pest repellent of the present invention, in addition to the piperidine derivative represented by the above formula (I), it is effective to use a repellent fragrance component in combination. Since the piperidine derivative is non-fragrant (has no odor peculiar to an insect repellent), when it is combined with a repellent perfume component, it hardly affects the original fragrance of the repellent perfume component. Accordingly, the piperidine derivative is a repellent component having good compatibility with a repellent fragrance component.

The repellent perfume component capable of being combined with piperidine derivative comprises (a) hydrocarbon aldehydes and/or hydrocarbon ketones having 8-16 total carbon atoms and (b) monoterpene alcohols and/or aromatic alcohols having 8-12 total carbon atoms. The repellent fragrance component (a) and the repellent fragrance component (b) may be used alone or in combination.

Examples of the repellent fragrance component (a) include: decanal, undecanal, dodecanal, 2-methylundecanal, tridecanal, 10-undecenal, citronellal, citral, neral, phenylacetaldehyde, cinnamaldehyde, α -amyl cinnamaldehyde, α -hexyl cinnamaldehyde, convallaldehyde, perillaldehyde, 3, 5-dimethyl-3-cyclohexene-1-formaldehyde, cuminaldehyde, piperonal, tridecanone, l-carvone, menthone, pulegone, cis-jasmone, dihydro-jasmone, α -damascone, β -damascone, α -ionone, β -ionone, 2-amyl cyclopentanone, 2-hexyl cyclopentanone, 2-heptyl cyclopentanone, methyl benzyl ketone, and methyl styryl ketone. These repellent fragrance components of (a) may be used alone or in combination of a plurality of them.

Examples of the repellent perfume component (b) include: linalool, dehydrolinalool, dihydromyrcenol, geraniol, nerol, citronellol, menthol, terpineol, terpinen-4-ol, isopulegol, borneol, 1-phenylethyl alcohol, 2-phenylethyl alcohol, cinnamyl alcohol, thymol and eugenol. These repellent fragrance components (b) may be used alone or in combination of two or more.

When the repellent perfume component (a) and the repellent perfume component (b) are used in combination, the blending ratio (a)/(b) is preferably set to 0.1/1 to 9/1, more preferably 0.5/1 to 1.4/1, in terms of weight ratio. When the blending ratio (a)/(b) is in the above range, a repellent effect (synergistic effect) enhanced by the different types of repellent fragrance components (a) and (b) is obtained, and it is pleasant even if fragrant. When the blending ratio (a)/(b) is smaller than 0.1/1 or when the blending ratio (a)/(b) is larger than 9/1, it becomes difficult to enjoy the synergistic effect by using the repellent perfume components (a) and (b) of different kinds in combination.

The pest repellent of the present invention may further contain (c) a hydrocarbon ester having 8 to 16 carbon atoms in total as a repellent fragrance component different from the above (a) and (b). The repellent perfume component of the above (c) is a component which can contribute to enhancing the repellent effect on a specific exotic ant in cooperation with the repellent perfume component of the above (a) and the repellent perfume component of the above (b).

Examples of the repellent perfume component (c) include: decyl acetate, linalyl acetate, geranyl acetate, citronellyl acetate, menthyl acetate, terpinyl acetate, neryl acetate, p-tert-butylcyclohexyl acetate, tricyclodecenyl propionate, tricyclodecenyl isobutyrate, benzyl acetate, phenylethyl acetate, styryl acetate, cinnamyl propionate, allyl hexanoate, allyl heptanoate, methyl benzoate, ethyl benzoate, 3-hexenyl benzoate, benzyl benzoate, methyl cinnamate, ethyl cinnamate, methyl salicylate, ethyl salicylate, pentyl salicylate, methyl jasmonate, and methyl dihydrojasmonate. These repellent fragrance components of (c) may be used alone or in combination of a plurality.

The pest repellent of the present invention may contain components other than the repellent fragrance component as necessary. Examples of such components include: hydrocarbons such as d-limonene, α -pinene and β -pinene, isoamylphenyl ethyl ether, linalool oxide, 1, 8-cineole, rose oxide (Japanese: ローズオキサイド), diphenyl ether, mackerel (Japanese: マグノラン), rhubarb furan (Japanese: ルバフラン), hydrocarbon ethers such as indanyl-2, 4-dioxane, nitrogen-containing compounds such as 2, 6-dimethyl-3-ethylpyrazine, citronellonitrile, stemonone (Japanese: ステモン) and o-aminoacetophenone, sandalwood oil and spearmint oil, essential oils such as thyme white oil, patchouli oil, garlic oil, cinnamon leaf oil, thyme red oil, jasmine oil, orange flower oil (Japanese: ネロリ oil), bergamot oil, orange oil, geranium oil, orange leaf oil, lemon oil, lemongrass oil, cinnamon oil, eucalyptus oil, and eucalyptus citriodora oil.

Further, it is effective that the pest repellent of the present invention contains glycols and/or glycol ethers. The glycols and/or glycol ethers function not only as a solvent for the repellent component or repellent fragrance component, but also as a repellent effect-sustaining component for sustaining the repellent effect of the repellent component or repellent fragrance component. The reason for this is that the glycols and/or glycol ethers have a higher vapor pressure than the piperidine derivative. When a glycol and/or a glycol ether is added to a piperidine derivative, excessive volatilization of the piperidine derivative is suppressed, and as a result, a repellent effect against a specific foreign ant based on the piperidine derivative can be sustained for a long period of time.

Examples of the glycols and/or glycol ethers that can be used as the repellent effect-sustaining component include: propylene glycol (10.7Pa), dipropylene glycol (1.3Pa), tripropylene glycol (0.67Pa), diethylene glycol (3Pa), triethylene glycol (1Pa), 1, 3-butanediol, hexanediol (6.7Pa), benzyl glycol (2.7Pa), diethylene glycol monobutyl ether (3Pa), dipropylene glycol monobutyl ether, and tripropylene glycol monomethyl ether. The parenthesized values described after the names of the respective substances are vapor pressures at 20 ℃. Among these glycols and/or glycol ethers, dipropylene glycol is a preferred repellent effect sustaining component. The content of the repellent effect-sustaining component is preferably 0.2 to 10 times the content of the repellent component and the repellent fragrance component.

In the pest repellent of the present invention, functional components such as deodorizing components, sterilizing components, antibacterial components and the like may be added if the substance or component does not interfere with the repellent effect of a specific foreign ant. The deodorant component is typically extract of plants of Gramineae, Theaceae, Ginkgoaceae, Oleaceae, Moraceae, Rutaceae, Saxifragaceae, and Ebenaceae. In addition, a relaxing effect can be provided by blending a so-called "green fragrance" such as geraniol or geranial.

The pest repellent of the present invention is preferably one that does not substantially contain an insecticidal component. The phrase "substantially not containing" does not mean that the content of the pesticidal component is strictly 0% in any case. For example, a case where an extremely small amount of an insecticidal component is unintentionally contained or a case where the effect as the insecticidal component is not exhibited even if the extremely small amount of the insecticidal component is intentionally contained may be regarded as an insect repellent containing substantially no insecticidal component. Examples of the case where an extremely small amount of an insecticidal component is unintentionally contained include: in the production equipment of the pest repellent, in the case of producing other products containing an insecticidal component in the past, an extremely small amount of the insecticidal component adhering to a container or a pipe is mixed as a contaminant into the pest repellent; examples of the insect repellent include those in which an insecticidal component floating or volatilizing in the air in the production room is absorbed into the insect repellent being produced and mixed. In such a case, even a case where the insect repellent contains an extremely small amount of an insecticidal component is regarded as an insect repellent containing substantially no insecticidal component.

Although the pest repellent of the present invention does not substantially contain an insecticidal component, the piperidine derivative as an essential component in the pest repellent of the present invention has a high repellent effect against specific foreign ants, and therefore exhibits a repellent effect equal to or greater than that of a repellent containing a conventional insecticidal component. Further, the pest repellent of the present invention containing substantially no insecticide can be a pest repellent having less resistance to daily use even for consumers allergic to the insecticide component. In addition, the pest repellent of the present invention can be expected to have a repellent effect even when the pest has become resistant to conventional repellent components such as mosquito repellent amine.

[ Pest-repellent preparations ]

The pest repellent of the present invention can be used for repelling a specific foreign ant without any special processing, but is prepared in an easy-to-use formulation and is practically used as a pest repellent product containing 0.01 to 99 w/w% of the pest repellent. The formulation of the pest repellent product is typically a liquid preparation, a gel preparation, or a solid preparation.

Examples of the liquid preparation and the gel preparation include a liquid preparation, an emulsion, an aqueous solvent, a microemulsion, an aerosol, and a cream. In the liquid preparation and the gel preparation, the contents of various components such as a repellent component, a repellent perfume component, and a repellent effect-sustaining component in the preparation can be easily adjusted. Therefore, there is an advantage that the commercial properties of the pest repellent product can be easily changed, for example, by increasing the repellent component to enhance the repellent effect, or by increasing the repellent perfume component to produce a product having high fragrance.

Examples of the solid agent include powders, granules, and baits. The solid agent has an advantage of easy handling since there is no risk of liquid leakage or fingertip wetting. The pest repellent product formed as a solid agent can be prepared, for example, by supporting (impregnating) a suitable carrier with the pest repellent. When the pest repellent is carried on the carrier, a solvent, a surfactant or the like may be added if necessary. Examples of the carrier include: examples of the thermoplastic resin include various vegetable powders such as wood flour and wheat flour, base fabrics such as paper, woven fabric and nonwoven fabric, porous organic molded products such as viscoseal (japanese: ビスコパール), inorganic carriers such as kaolin, talc, calcium carbonate, silica sand and ceramics, films or molded products made of polyethylene, polypropylene, ethylene/vinyl acetate copolymer (EVA), ethylene/methyl methacrylate copolymer (EMMA), styrene-based diblock polymer, styrene-based triblock polymer, thermoplastic resin elastomers (TPE and TPO), and silicone rubber. For example, when the carrier is a nonwoven fabric, the following are listed: a method for keeping the pest repellent by a liquid medicine distribution mode and a coating mode; or embedding with paraffin. In the case where the support is a film or a molded body, there may be mentioned: a method of retaining the pest repellent by a liquid medicine dispensing manner or a coating manner; or a method in which the insect repellent is sprayed or dropped together with a solvent to be impregnated into the film or the molded body. In the case where the carrier is silicone rubber, there may be mentioned: a method in which silicone rubber containing an insect repellent at a high concentration and untreated silicone rubber are put into a closed container, left for a certain period of time, and the concentration of the insect repellent is averaged over the entire silicone rubber.

The amount of the pest repellent to be incorporated in the pest repellent product is appropriately adjusted depending on the use, the period of use, the method, and the like of the pest repellent product, but is preferably 0.01 to 20 w/v% in the case of a liquid or gel preparation, and is preferably 0.01 to 10 w/w% in the case of a solid preparation. For example, in the case of a solid agent using a carrier, it is preferable that 10 to 50mg of the pest repellent is contained in each of the pest repellent products assuming a use period of 8 to 12 hours. In the pest repellent products assuming a use period of 15 to 30 days, it is preferable that each product contains 100 to 2000mg of the pest repellent.

When preparing the pest repellent product, a solvent, a surfactant, a cosolvent, a gelling agent, a dispersant, a stabilizer, a pH adjuster, a colorant, and the like may be added as required. Examples of the solvent include water, lower alcohols such as ethanol and isopropanol, ketone solvents, ester solvents, and hydrocarbon solvents such as normal paraffins and isoparaffins. Examples of the surfactant include: nonionic surfactants such as polyoxyethylene hydrogenated castor oil, polyoxyethylene higher alkyl ethers (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, etc.), polyoxyethylene alkylphenyl ethers, polyoxyethylene higher fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene glycerin fatty acid esters, polyoxyethylene polyoxypropylene alkyl ethers, etc., and higher alkylamine oxide surfactants such as laurylamine oxide, stearylamine oxide, laurylamidopropyldimethylamine oxide, etc. Examples of the gelling agent include polyvinyl alcohol, alginic acid, and carrageenan.

The pest repellent product of the present invention is used in a wide variety of fields depending on the formulation. Pest repellent products formed as liquid preparations are used, for example, as spray products to be spread on objects or the environment. Pest repellent products formed as gel preparations are used, for example, as coating products to be applied to the skin of a human body. Pest repellent products formed as solid agents are used by being spread or placed in a predetermined amount around doorways, kitchens, toilets, living rooms, bedrooms, warehouses, vehicles, balconies, porches, courtyards, houses, and the like. In particular, in the case where the pest-repellent article is a solid agent, since a three-dimensional barrier is formed so that specific foreign ants do not come close with the pest-repellent article as a center, the repellent effect can be exerted in a wide range. The insect repellent product formed by supporting the insect repellent on the molded body or the silicone rubber can be used by wrapping the insect repellent around an ankle, a shoe, or the like as a band, or by attaching the insect repellent to a shoe in the form of a fixing tool such as a clip. In the case of a pest repellent product formed by supporting a pest repellent on a sticker or a film, an adhesive layer may be provided on the lower surface of a carrier and the product may be used by attaching the product to the lower part of trousers or shoes.

The application amount of the pest-repellent product may be appropriately adjusted according to the formulation. In the liquid or gel preparation, the application amount is preferably 10 to 50mL/m². The application amount is less than 10mL/m²In the case of the application, a sufficient repellent effect cannot be expected, and the application amount exceeds 50mL/m²In time, discomfort is increased due to stickiness. In the solid agent, the application amount is preferably 10-50 g/m². The application amount is less than 10g/m²In the case of using the composition, a sufficient repellent effect cannot be expected, and the amount of the composition to be applied is more than 50g/m²It is not economical because the repelling effect is also hardly changed.
