Description

The present invention relates to a Drosophila outbreak preventive agent and a Drosophila outbreak aerosol product that prevent the outbreak of Drosophila.

Conventionally, there have been pests that live by using kitchen waste as a habitat, spawning place, and food, and aerosol agents used for such pests are known (see, for example, Patent Document 1). The aerosol agent of Patent Document 1 contains a pyrethroid insecticide such as allethrin and phthalthrin, and is used by spraying it on a plastic container containing garbage mixed with meat, fish, and vegetables discharged from ordinary households. Is something that can be done. In addition, Patent Document 1 also describes test results regarding the presence or absence of spawning of pests due to spray treatment or non-treatment of an aerosol agent, the presence or absence of a killing effect, and the like.

Japanese Unexamined Patent Publication No. 4-247004

By the way, for example, in Test Example 6 of Patent Document 1, it has been confirmed that the effect of the aerosol agent on preventing spawning of houseflies lasts for 5 hours, but the longer-lasting effect is unknown. In addition, in Test Example 7, the number of emergences after 10 days was observed, but since it was only confirmed that the housefly larvae were definitely dead after 10 days, the sustained effect of the aerosol agent for 10 days was confirmed. Not what I did.

On the other hand, in the home, the outbreak of so-called flies (Psychodidae, Drosophila, etc.) becomes a problem. In this respect, it is unclear how long the effect of preventing the occurrence of flies is sustained by the aerosol agent of Patent Document 1.

The present invention has been made in view of the above points, and an object of the present invention is to provide an agent capable of preventing the outbreak of Drosophila for a long period of time.

In order to achieve the above object, in the present invention, a drug having a repellent action and a solvent having low hydrophilicity are used.

The first invention is characterized in that it contains a drug that exerts a repellent action against flies and liquid paraffin in which the drug dissolves.

According to this configuration, since the hydrophilicity of liquid paraffin is low, it is possible to suppress the outflow and decomposition of chemicals even when used in a place with a large amount of water such as kitchen waste, and it is possible to prevent flies from approaching for a long period of time. .. Moreover, at this time, for example, eggs and larvae that have already been laid on the kitchen waste can be exterminated, so that it is possible to prevent the generation of flies on the kitchen waste for a long period of time. Examples of the drug exhibiting a repellent action include transfluthrin and the like.

The second invention is characterized by containing an insecticide that exerts an insecticidal action on flies.

According to this configuration, for example, when used for kitchen waste, the flies that have approached the kitchen waste can be killed by the insecticidal action of the insecticide.

The third invention is characterized by containing transfluthrin and phenothrin.

According to this configuration, phenothrin is less likely to transpire than transfluthrin and has a long-term residual effect. Therefore, for example, after the repellent action of transfluthrin diminishes, the insecticidal action of phenothrin continues. Therefore, the high outbreak prevention effect can be maintained for a longer period of time.

The fourth invention is characterized by containing an antibacterial agent.

According to this configuration, when used for, for example, kitchen waste, the generation of the odor of kitchen waste can be prevented for a long period of time.

A fifth invention is an aerosol product for preventing the occurrence of flies, which comprises an aerosol agent containing the agent for preventing the occurrence of flies and an aerosol container in which the agent for preventing flies is contained.

According to this configuration, the flies generation preventive agent can be sprayed from the aerosol container and used, and for example, the flies generation preventive agent can be attached to a wide range of the kitchen waste or the container containing the food waste.

A sixth invention relates to an aerosol product for preventing the occurrence of flies.
It is characterized by including a fixed-quantity injection valve that injects a certain amount of the aerosol agent in the aerosol container by one injection operation.

Since the so-called fixed-quantity injection valve does not inject an amount exceeding a certain amount when the user performs an injection operation, it is possible to inject a necessary amount that can prevent the occurrence of flies and an insecticidal effect, which makes it easier to use. .. The fixed amount is not the total amount of the aerosol agent contained in the aerosol container, but less than the amount of the aerosol agent contained in the aerosol container, for example, set in the range of 0.09 ml to 3.0 ml. Can be left.

The seventh invention is characterized in that the average particle size of the particles ejected from the aerosol container is 20 μm or more and 120 μm or less, and the particle concentration ejected from the aerosol container is 2000 or more.

According to this configuration, if an aerosol agent is sprayed toward a flies such as Drosophila and Drosophila while they are flying, the particles are likely to adhere to the flies and the number of particles adhering to the flies increases. Drosophila can be exterminated by the effects of liquid paraffin and chemicals. That is, with the above configuration, the effect can be suitably exhibited not only as an agent for preventing the occurrence of flies but also as an aerosol agent for directly spraying and exterminating flies.

According to the present invention, since it contains a drug that exerts a repellent action against flies and liquid paraffin in which the drug dissolves, the occurrence of flies can be prevented for a long period of time when used for kitchen waste, for example. can.

It is a front view of the flies prevention aerosol product which concerns on embodiment of this invention. It is a graph which shows the flies approach prevention rate of an Example and a comparative example.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is essentially merely an example and is not intended to limit the present invention, its application or its use.

FIG. 1 is a front view of an aerosol product 1 for exterminating flies according to an embodiment of the present invention. The Drosophila extermination aerosol product 1 includes an aerosol agent for exterminating Drosophila, an aerosol container 10 containing an aerosol agent for exterminating Drosophila, an injection button 11, and a fixed-quantity injection valve 12.

The aerosol container 10 is made of a pressure-resistant material, and the content can be set between, for example, about 80 ml to 200 ml. A metering injection valve 12 is provided above the aerosol container 10. The fixed-quantity injection valve 12 is a valve configured to inject a fixed amount of the Drosophila extermination aerosol agent in the aerosol container 10 by one injection operation. Since the fixed-quantity injection valve 12 has been well known in the past, detailed description thereof will be omitted.

An injection button 11 is connected to the metering injection valve 12. When the user pushes the injection button 11 downward, the metering injection valve 12 is opened. When the user keeps pressing the injection button 11, a certain amount of the aerosol agent for exterminating Drosophila is injected from the fixed quantity injection valve 12, and then the closed state is obtained, and further injection is suppressed. That is, when the user performs the injection operation, an amount exceeding a certain amount is not injected, so that the necessary amount that can obtain an immediate drop effect, an insecticidal effect, and an outbreak prevention effect on the flies can be injected, which facilitates use. .. The fixed amount is not the total amount of the flies exterminating aerosol agent contained in the aerosol container 10, but is less than the amount of the flies exterminating aerosol agent contained in the aerosol container 10, for example, 0.09 ml to 3 It can be set in the range of 0.0 ml. In this example, it is set to 1 ml.

An injection port 11a is opened in the front portion of the injection button 11. The injection port 11a communicates with the metering injection valve 12 via a flow path (not shown) provided inside the injection button 11. Therefore, the aerosol agent for exterminating flies that has flowed out of the aerosol container 10 when the fixed-quantity injection valve 12 is opened flows through the flow path of the injection button 11 and is injected from the injection port 11a. The shape and structure of the injection button 11 are not particularly limited, and any shape and structure may be used.

The average particle size of the particles ejected from the injection port 11a is 20 μm or more and 120 μm or less. The size of the average particle size can be changed depending on the diameter of the injection port 11a, the shape and length of the flow path, the amount of the propellant, and the like. The average particle size is preferably 25 μm or more. The average particle size is preferably 115 μm or less. The basis for setting the average particle size will be described based on the test results described later. As the average particle size measuring device, a laser light diffraction type particle size measuring device Microtrac Aerotrac LDSA-SPR 1500A (manufactured by Microtrac Bell Co., Ltd.) was used. The particle size of the aerosol for exterminating flies was measured under the conditions of a temperature of 25 ° C. and an injection distance of 30 cm, and the 50% particle size (D50) in the volume integration distribution was taken as the average particle size.

The particle concentration (CNC) injected from the injection port 11a is 2000 or more. The particle concentration injected from the injection port 11a is preferably 2500 or more. It is considered that the higher the particle concentration, the easier it is for the particles to hit the insect body and the higher the effect, but the practical upper limit of the particle concentration can be 5000 or less, and 4500 or less is more preferable. The basis for setting the particle concentration will be described based on the test results described later. The LDSA-SPR 1500A was used as the particle concentration (CNC) measuring device, and the measurement was performed under the conditions of a temperature of 25 ° C. and an injection distance of 30 cm. The particle concentration (CNC) is a concentration index calculated from the light intensity scattered by the particles, and can be measured by using the particle size measuring device of the laser light diffraction method.

The aerosol agent for exterminating flies contains neothiosol, which is a liquid paraffin, and a propellant, and is housed in the aerosol container 10 for use. The flies exterminating aerosol agent can be composed of a stock solution containing neothiosol and a propellant. The undiluted solution may contain only neothiosol, or may contain a drug other than neothiosol. The propellant may be a mixture of liquefied petroleum gas (LPG) only, dimethyl ether (DME) only, liquefied petroleum gas and dimethyl ether. The propellant may be other than liquefied petroleum gas and dimethyl ether, and may be any propellant capable of achieving the above-mentioned average particle size and particle concentration.

The Drosophila extermination aerosol agent may contain an insecticide that exerts an insecticidal action against Drosophila, a repellent that exerts a repellent action against Drosophila, and a synergistic agent that enhances the insecticidal effect. Insecticides include, for example, aresulin, tetramesrin, pyrethrin, phenothrin, resmethrin, cyfluthrin, permethrin, cypermethrin, deltamethrin, tralomethrin, cyfluthrin, flamethrin, imiprothrin, etofemprox, fenvalerate, phenproprin Mepafluthrin, dimefluthrin, transfluthrin, 2-methyl-4-oxo-3- (2-propynyl) -cyclopent-2-enyl-3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate Pyrethroid compounds such as dichlorvos, fenitrothione, tetrachlorobinphos, fentione, chlorpyriphos, diazinon and other organic phosphorus compounds, propoxer, carbalyl, methoxadiazone, phenocarb and other carbamate compounds, lufenuron, chlorfluazuron, hexaflumron, diflubenzuron. , Cyfluthrin, 1- (2,6-difluorobenzoyl) -3- [2-fluoro-4- (1,1,2,3,3,3-hexafluoropropoxy) phenyl] urea and other chitin formation inhibitors, Examples thereof include immature hormone-like substances such as pyriproxyfen, metoprene, hydroprene and phenoxycarb, and N-phenylpyrazole compounds such as fipronil.

Examples of the repellent include N, N-diethyl-m-toluamide, limonene, linalol, citronellal, menthol, menthon, hinokithiol, geraniol, eucalyptol, indoxacarb, kalan-3,4-diol, 2-( 2-Hydroxyethyl) -1-piperidincarboxylic acid 1-methylpropyl ester, 3- (Nn-butyl-N-acetyl) aminopropionic acid ethyl ester, P-menthane-3,8-diol and the like can be mentioned. Some insecticides also have a repellent effect, and examples of such agents include transfluthrin and the like.

Examples of the synergist include piperonyl butoxide, MGK264, S421, IBTA, cinepyrin 500 and the like.

The Drosophila extermination aerosol agent can be used by directly injecting it onto the Drosophila, and at this time, it exerts an immediate drop effect of immediately dropping the Drosophila. This is because neothiosol contained in the aerosol agent for exterminating Drosophila adheres to the insect body of Drosophila and causes it to fall by a physical action such as inhibiting flapping or making the insect body heavier. The dropping effect can be obtained extremely quickly as compared with the case of dropping by the action of a drug such as an insecticide.

Further, when the insecticide or the repellent is contained as described above, the aerosol agent for exterminating Drosophila also exhibits the effect of preventing the occurrence of Drosophila by spraying it on, for example, kitchen waste. That is, a flies outbreak preventive agent can be composed of an insecticide or a repellent contained in an aerosol agent for exterminating flies and liquid paraffin.

Specifically, it is as follows. That is, by spraying this agent for preventing the development of flies on a place where flies are likely to occur, such as kitchen waste, eggs and larvae already laid on the food waste can be exterminated. In addition, the insecticide or repellent contained in the flies development preventive agent can kill or repel the flies that come to the kitchen waste, so that spawning can be prevented. And, among the components that make up the Drosophila outbreak preventive agent, the hydrophilicity of liquid paraffin is low, so even if it is used in a place with a lot of water such as kitchen waste, the outflow and decomposition of insecticides and repellents will occur. It is suppressed and can prevent flies from approaching for a long period of time. In this way, eggs and larvae that have already been laid can be exterminated, and spawning can be prevented for a long period of time, so that, for example, the occurrence of flies on kitchen waste can be prevented for a long period of time.

The aerosol agent for exterminating flies may contain an antibacterial agent. By containing an antibacterial agent, it is possible to prevent the generation of the odor of kitchen waste for a long period of time when the aerosol agent for exterminating flies is used for, for example, kitchen waste. Examples of the antibacterial agent include isopropylmethylphenol, chlorine dioxide, iodine, thymol, formaldehyde, glutaraldehyde, ethanol, propyl alcohol, phenol, cresol, phenoxyethanol, cetylpyridinium chloride and the like.

(Immediate drop test)
Table 1 shows the composition of the aerosol agent for exterminating flies according to the examples.

Table 2 shows the results of immediate drop tests of Examples 1, 2 and 3 and Comparative Examples 1 and 2.

The first embodiment is an example in which the aerosol container 10 is used when the diameter of the injection port 11a of the injection button 11 is 1.5 mm. The second embodiment is an example in which the aerosol container 10 is used when the diameter of the injection port 11a of the injection button 11 is 1.2 mm. Example 3 is an example in which the aerosol container 10 is used when the diameter of the injection port 11a of the injection button 11 is 0.9 mm.

On the other hand, Comparative Example 1 is an example in which the aerosol container 10 is used when the diameter of the injection port 11a of the injection button 11 is 0.5 mm, and the composition of the aerosol agent is the same as in Examples 1, 2 and 3. .. Further, Comparative Example 2 is an example of spraying using a commercially available hand spray, and the composition is the same as that of the stock solutions of Examples 1, 2 and 3.

The test method is as follows. Ten test insects were released into a glass ring having a diameter of 10 cm and a height of 5 cm, and the reagent agent was sprayed once from a distance of about 30 cm. Then, it was confirmed whether or not the test insects would fall.

In Examples 1, 2 and 3, the average particle size is in the range of 20 μm or more and 120 μm or less, and the particle concentration is 2000 or more. In Examples 1, 2 and 3, when sprayed toward a plurality of flying flies, the majority of flies immediately fell. That is, the immediate drop effect was sufficiently obtained. The test insects are adult Drosophila melanogaster and adult Psychodidae.

In Comparative Example 1, the average particle size is less than 20 μm, specifically less than 10 μm, and the particle concentration is less than 400. In this case, even if it was sprayed toward the flying fly, it hardly fell and continued to fly, so that the immediate drop effect was extremely weak.

In Comparative Example 2, the average particle size exceeds 80 μm and the particle concentration is less than 2000. In this case, there were few individuals that fell even if they were sprayed toward the flying flies, and many individuals continued to fly, so the immediate fall effect was weak.

As shown in the above results, it was clarified that the effect of immediate drop can be obtained for the first time by setting the average particle size in a predetermined range and the particle concentration above a predetermined range. The reason for this has not been fully elucidated, but in addition to the fact that it is thought that a certain level of particle concentration is required for insects that fly around quickly, such as fruit flies, the particles of fruit flies are too small due to their small size. It is thought that it is difficult to hit the particles, and if the particles are too large, the light insects of Drosophila will be blown away by the turbulence of the airflow generated around them and cannot be contacted.

As described above, the average particle size of the particles ejected from the injection port 11a is 20 μm or more and 120 μm or less, and the particle concentration is 2000 or more. , The immediate drop effect can be significantly enhanced. By setting the average particle size to 25 μm or more, the immediate drop effect can be further enhanced, and by setting the average particle size to 115 μm or less, the immediate drop effect can be further enhanced.

Further, by setting the concentration of the particles ejected from the injection port 11a to 2500 or more, the immediate drop effect can be further enhanced. By setting the upper limit of the particle concentration to 5000 or less, an unnecessary increase in concentration is suppressed, and the effect of the aerosol agent for exterminating flies can be sufficiently obtained without increasing the amount of the aerosol agent for exterminating flies. By setting the upper limit of the particle concentration to 4500 or less, the aerosol agent for exterminating flies can be used efficiently.

It should be noted that this immediate drop effect is a physical action of neothiosol adhering to the insect body of the flies to prevent flapping or to make the insect body heavier, so that the flies immediately after the fall are still present. It is alive and may move around. In this regard, since the aerosol agent for exterminating flies in Examples 1, 2 and 3 contains transfluthrin, which is an insecticide having an excellent knockdown effect, the fallen flies will soon stop their activity due to the knockdown action. And finally death.

(Spray test from a long distance)
Next, a spray test from a relatively long distance will be described. The test method is as follows. Twenty test insects were released into a glass ring having a diameter of 9 cm and a height of 6 cm, and the reagent agent was sprayed once from a distance of 150 cm. Then, the case fatality rate after 24 hours was calculated. The test insect is an adult Drosophila. As the reagent agent, the above-mentioned Example 2 and the one obtained by removing phenothrin from the Example 2 (Comparative Example 3) were prepared.

As a result, in Example 2, the mortality rate after 24 hours was 100%, whereas in Comparative Example 3 in which phenothrin was removed, the mortality rate after 24 hours was 80%. As described above, when sprayed from a relatively long distance, the final mortality rate can be improved by adding phenothrin. In addition, when sprayed from this distance, some flies were not able to obtain the effect of immediate drop.

That is, when sprayed from a relatively long distance, the spray particles may not adhere sufficiently, so that the effect of immediate dropping cannot be sufficiently obtained, and the knockdown effect and lethality of transfluthrin are also insufficient (compared to the above). It is probable that it was (in the case of Example 3). In this respect, since the phenothrin contained in Example 2 is an insecticidal component excellent in a reliable lethal effect even in a small amount, it can finally lead to death even when the spray particles do not sufficiently adhere to the flies. In this way, even when spraying from a long distance where it is difficult to drop immediately, the final extermination effect can be ensured by adding phenothrin.

(Fixation prevention effect confirmation test)
The colonization prevention effect confirmation test is an effect confirmation test for the prevention of flies. Explaining the test method, first, the aerosol agent for exterminating Drosophila of Example 4 shown in Table 3 and the aerosol agent of Comparative Example 4 shown in Table 4 were prepared. In each case, the injection button 11 used was the same as that of the second embodiment (the diameter of the injection port 11a was 1.2 mm).

Example 4 contains kerosene (neothiosol), and Comparative Example 4 contains a synthetic alcohol instead of kerosene.

An orange according to an example in which the aerosol agent for exterminating flies of Example 4 was sprayed once on the cut surface, an orange according to a comparative example in which the aerosol agent of Comparative Example 4 was sprayed once on the cut surface, and an untreated orange. Prepared. Fourteen days after preparing these oranges, the oranges according to the examples, the oranges according to the comparative examples, and the untreated oranges were allowed to stand in a 25 cm × 25 cm acrylic box, and the test insects (Drosophila melanogaster) were placed in the acrylic box. Drosophila) was released, and 2 hours later, the number of test insects approaching each orange was confirmed. In addition, 21 days after preparing the above oranges, the number of test insects approaching each orange was confirmed in the same manner. Then, the approach prevention rate (also referred to as the fixing prevention rate) was calculated based on the following formula. The number of flies that are close to the orange refers to the number of flies that are close to the orange in a living state, and the flies that die in contact with the orange are not counted.

Anti-slip rate (%) = (number of unprocessed leans-number of processed leans) / number of unprocessed leans x 100

As is clear from Table 5 and FIG. 2, the approach prevention rate is higher in Example 4 containing kerosene than in Comparative Example 4 containing synthetic alcohol, and the difference is particularly widened after a long period of time. is doing. This is because kerosene, which is a liquid paraffin, has low hydrophilicity, so even when it is used in a place with a lot of water such as orange, the outflow of pesticides or repellents (transfluthrin in this test) can occur. This is because it is possible to suppress decomposition and prevent flies from approaching for a long period of time.

Moreover, when the same test was carried out with the aerosol agent for exterminating flies of Example 2, it was confirmed that the approach prevention rate after a long period of time was further higher than that of Example 4. That is, as compared with the case of transfluthrin alone (Example 4), a long-term approach prevention effect can be obtained by further containing phenothrin (Example 2). Transfluthrin has a spatial repellent effect and a knockdown effect, so it can be expected to have a high anti-adhesion effect especially in the early stage, while phenothrin has a high lethal effect even in a small amount, so it is expected to have an effect of maintaining the anti-adhesion effect for a longer period of time. can.

The test insect used in the above-mentioned anti-fixation effect confirmation test was Drosophila melanogaster, but similar results can be obtained with flies such as Psychodidae. Further, although orange was used in the above-mentioned anti-fixation effect confirmation test, the same result can be obtained by performing the above-mentioned test using kitchen waste such as meat, fish, and vegetables other than orange.

(Hatching prevention effect confirmation test)
The hatching prevention effect confirmation test is the same as the above test, and is an effect confirmation test for prevention of the outbreak of flies. Explaining the test method, first, three oranges as a fixing substance were prepared, and each of them was allowed to stand in a room where Drosophila breeded for 3 days to lay eggs on Drosophila. Next, one of the three oranges spawned was sprayed with the aerosol for exterminating the flies of Example 2 once, and the other one was sprayed with the aerosol for exterminating the flies of Example 4 once, and the remaining 1 was sprayed. One was unprocessed. Each orange was stored for 14 days, and the presence or absence of adult Drosophila was confirmed.

As a result, more than 200 flies were generated in the untreated oranges, whereas the number of oranges according to Example 2 was 0 and the number of oranges according to Example 4 was 5. That is, by treating the source of Drosophila with an aerosol agent for exterminating Drosophila, it is possible to prevent the hatching of eggs that have already been laid or to exterminate the larvae that have already hatched.

As described above, by treating the source of Drosophila with an aerosol agent for exterminating Drosophila, eggs and larvae that have already been laid can be exterminated. After that, as shown in the colonization prevention effect confirmation test, it is possible to prevent the imago from approaching for a long period of time, so that it is possible to prevent the flies from spawning at the source. As described above, the outbreak of flies can be prevented for a long period of time.

(Action and effect of the embodiment)
As described above, according to this embodiment, when a small and fast-moving pest such as Drosophila or Drosophila is flying, when an aerosol agent for exterminating the flies is sprayed toward the flies, the particles become flies. In addition to being more likely to adhere to the flies, the number of particles adhering to the flies also increases, and an immediate drop effect can be obtained. This eliminates the need for non-volatile components such as cooking oil, which makes it easier to use, for example, indoors. Further, the fixed-quantity injection valve 12 can spray only the amount necessary for dropping the flies in the place without waste.

In addition, if the ejected particles do not hit the insect body, the immediate drop effect may not be sufficiently obtained, but even in this case, since a highly lethal drug such as phenothrin is arranged. , It can be lethal in the end, and a more reliable extermination effect can be obtained.

Further, by blending a drug having a high knockdown effect such as transfluthrin, a high extermination effect can be realized because the flies that have fallen immediately by hitting the particles are knocked down immediately.

Further, since the liquid paraffin contained in the aerosol agent for exterminating flies has low hydrophilicity, it is possible to prevent flies from approaching for a long period of time even when used in a place having a large amount of water such as kitchen waste. Moreover, at this time, for example, eggs and larvae that have already been laid on the kitchen waste can be exterminated, so that it is possible to prevent the generation of flies on the kitchen waste for a long period of time.

As described above, by using an aerosol agent having a predetermined particle size in which transfluthrin, phenothrin and kerosene are blended, it is possible to provide an aerosol having excellent preventive effect by direct spraying on Drosophila and objective treatment.

Further, since the particle size in the above range is likely to spread in an indoor space or the like, the aerosol product 1 using the fixed-quantity injection valve 12 can be used as a space treatment agent for treating the entire indoor space with a single spray treatment. It can also be used. That is, in this case, by injecting the Drosophila extermination aerosol agent once toward the indoor space, the spray particles containing transfluthrin and phenothrin spread throughout the space, so that a space without Drosophila can be realized.

Conventionally, as a space treatment agent for flies, ethanol has been used as a solvent. In this respect, since kerosene is used as the solvent in the present invention, the diffusibility is inferior to that of the highly volatile ethanol preparation. Therefore, in the present embodiment, the fixed-quantity injection valve 12 is used to inject 1 ml of an aerosol agent having a larger capacity than the conventional one. By using such a large-capacity fixed-quantity injection valve 12, the contents are sprayed vigorously at one time, so that the diffusibility is improved. As a result, even in the present embodiment using kerosene as a solvent, it is possible to realize diffusivity equal to or higher than that of a conventional quantitative spray agent using ethanol as a solvent.

The above embodiments are merely exemplary in all respects and should not be construed in a limited way. Furthermore, all modifications and modifications that fall within the equivalent scope of the claims are within the scope of the present invention.

The airborne agent for exterminating flies can be an aerosol agent for kitchen waste that is directly sprayed on kitchen waste indoors or outdoors, or can be an aerosol agent for kitchen waste that is directly sprayed on a container that contains food waste. It can also be sprayed directly onto a kitchen sink or trash can. These are sources of flies, but they can also be sprayed into indoor spaces such as kitchens, dining rooms, and living rooms. It can also be used against flies flying in outdoor spaces.

As described above, the present invention can be used for exterminating, for example, Drosophila melanogaster and Psychodidae.
