Description

TECHNICAL FIELD The present invention relates to a fly outbreak prevention aerosol product for exterminating fly flies and a fly fly prevention method.

BACKGROUND ART Conventionally, pest control agents have been known that exterminate pests by physically inhibiting their behavior (for example, see Patent Document 1). The pest control agent of Patent Document 1 is a flying pest control agent that is sprayed toward flying pests. In order to drop the flying pests to which the flying pest control agent is attached, the flying pest control agent is composed of a liquid with a kinematic viscosity of 4 cst or more, and the above insecticide is further dropped onto the upper surface of the beeswax layer. Sometimes, it has lipophilicity such that the contact angle determined by the θ/2 method is 70° or less. Specifically, several examples containing polyoxyethylene, sorbitan monolaurate, sodium dodecyl sulfate, xanthan gum, neothiozole, and edible oil are disclosed, and in these examples, house flies, Aedes mosquitoes, A falling effect can be obtained against butterflies, fruit flies, etc.

On the other hand, Patent Document 1 describes a liquid formulation containing 100% neothiosole as a comparative example. Patent Document 1 states that in this comparative example, there is no falling effect on small flies such as butterflies and fruit flies, and that in an example in which edible oil is added to neothiosole, a falling effect on small flies can be obtained.

Japanese Patent Application Publication No. 2018-177686

Incidentally, fly flies may occur indoors, and in that case, it is desirable to exterminate them indoors, but the repellent of Patent Document 1 contains non-volatile edible oil etc. in order to obtain a dropping effect against fly flies. However, there is room for improvement in that it requires wiping after use indoors.

In addition, spraying with aerosol etc. is not always effective against small and quickly flying pests such as small flies, but the pesticide of Patent Document 1 requires that the sprayed droplets do not sufficiently adhere to the insect bodies. It is considered that a sufficient falling effect cannot be obtained.

The present invention has been made in view of the above, and an object thereof is to provide an aerosol agent for exterminating small flies that provides an immediate effect when sprayed directly against pests.

In order to achieve the above object, the present invention provides an aerosol agent containing neothiosole, and the average particle diameter range and the particle concentration range are set to predetermined ranges.

A first aspect of the present invention is an aerosol agent for exterminating small flies stored in an aerosol container, in which the average particle diameter of particles sprayed from the aerosol container is 20 μm or more and 120 μm or less, and the particle concentration sprayed from the aerosol container is 2000 μm or more. It is characterized by the above.

According to this configuration, when a fly extermination aerosol agent is injected toward a fly such as a butterfly or fruit fly while it is flying, the particles tend to adhere to the fly and the number of particles attached to the fly increases. This inhibits the fly's behavior and gives it an immediate falling effect.

In addition, in the comparative example of Patent Document 1 (in the case of only neothiosol), an immediate falling effect was not obtained, but this is because particles sprayed from an aerosol container are difficult to hit small and fast-moving insect pests such as fly flies. This is thought to be due to insufficient adhesion of neothiozole. In the present invention, since the particle diameter and particle concentration are within the above ranges, the particles sprayed from the aerosol container are more likely to hit the flies, and neothiosole provides an immediate effect on the flies. This eliminates the need for non-volatile components such as edible oil as in the comparative example of Patent Document 1, making it easier to use indoors, for example.

The aerosol agent for killing fly flies can be composed of a stock solution containing neothiosole and a propellant containing liquefied petroleum gas (LPG), dimethyl ether (DME), or the like. The stock solution may contain only neothiozole, or may contain drugs other than neothiozole. The propellant may be liquefied petroleum gas only, dimethyl ether only, or a mixture of liquefied petroleum gas and dimethyl ether.

A second invention is characterized in that the average particle diameter is 25 μm or more.

A third invention is characterized in that the average particle diameter is 115 μm or less.

By setting the average particle size injected from the aerosol container to 25 μm or more, and by setting the average particle size to 115 μm or less, the instant drop effect of the flies is further enhanced.

A fourth invention is characterized in that the particle concentration is 2500 or more.

According to this configuration, most of the particles sprayed from the aerosol container are likely to hit the flies, so that the immediate falling effect of the flies is further enhanced.

The fifth invention is characterized in that it contains an insecticide that exhibits an insecticidal action against fly flies.

According to this configuration, not only the immediate falling effect but also the insecticidal effect of the insecticide on the flies can be obtained, and the exterminating effect is further enhanced. In other words, if the sprayed particles do not hit the insect body, the instant fall effect may not be sufficient, but even in this case, highly lethal agents (insecticides) such as phenothrin are added. By doing so, it is possible to finally kill the insect, and a more reliable extermination effect can be obtained.

Furthermore, a drug having a knockdown effect such as transfluthrin may be added. As a result, a high extermination effect can be achieved because the flies that fall immediately after being hit by the particles are immediately knocked down.

A sixth aspect of the present invention is characterized in that it comprises the aerosol agent for exterminating small flies and an aerosol container in which the aerosol agent for exterminating minor flies is accommodated.

A seventh aspect of the present invention is an aerosol product for exterminating flies, characterized by comprising a metered injection valve that injects a fixed amount of the aerosol agent for exterminating flies in the aerosol container with one injection operation.

So-called metered injection valves do not spray more than a certain amount when the user performs the injection operation, so they can spray the necessary amount to achieve immediate fall effect and insecticidal effect on fly flies, making them easier to use. . The certain amount is not the entire amount of the aerosol agent for killing flies contained in the aerosol container, but is less than the amount of the aerosol agent for killing flies contained in the aerosol container, for example, 0.09 ml to 3.0 ml. It can be set within the range.

According to the present invention, since the aerosol agent contains neothiosole and the average particle diameter range and particle concentration range are set within predetermined ranges, immediate effects can be obtained when sprayed directly against flying pests.

FIG. 1 is a front view of an aerosol product for exterminating fly flies according to an embodiment of the present invention. It is a graph showing the fly attack prevention rate of Examples and Comparative Examples.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Note that the following description of preferred embodiments is essentially just an example, and is not intended to limit the present invention, its applications, or its uses.

FIG. 1 is a front view of an aerosol product 1 for exterminating fly flies according to an embodiment of the present invention. The aerosol product 1 for exterminating mites includes an aerosol agent for exterminating erect flies, an aerosol container 10 in which the aerosol agent for exterminating erect flies is stored, an injection button 11, and a metered injection valve 12.

The aerosol container 10 is made of a pressure-resistant material, and its content can be set, for example, between about 80 ml and 200 ml. A metered injection valve 12 is provided at the top of the aerosol container 10 . The metered injection valve 12 is a valve configured to inject a predetermined amount of the fly-killing aerosol agent in the aerosol container 10 with one injection operation. Since this quantitative injection valve 12 is conventionally well known, detailed explanation thereof will be omitted.

An injection button 11 is connected to the metered injection valve 12 . When the user presses the injection button 11 downward, the metered injection valve 12 is opened. When the user presses and holds the injection button 11, a certain amount of the aerosol agent for killing flies is injected from the metered injection valve 12, and then the valve is closed and further injection is suppressed. In other words, when the user performs the spray operation, the amount will not exceed a certain amount, so it is possible to spray the necessary amount to obtain immediate fall effect, insecticidal effect, and prevention effect on fly flies, making it easier to use. . The certain amount is not the total amount of the aerosol agent for killing flies contained in the aerosol container 10, but is less than the amount of the aerosol agent for killing flies contained in the aerosol container 10, for example, from 0.09 ml to 3 ml. It can be set in the range of .0ml. In this example, it is set to 1 ml.

An injection port 11a is opened in the front part of the injection button 11. The injection port 11a communicates with the metered injection valve 12 via a flow path (not shown) provided inside the injection button 11. Therefore, the aerosol agent for killing flies that flows out of the aerosol container 10 when the metered injection valve 12 is opened flows through the flow path of the injection button 11 and is ejected from the injection port 11a. The shape and structure of the injection button 11 are not particularly limited, and may be any shape or structure.

The average particle diameter of the particles injected from the injection port 11a is set to be 20 μm or more and 120 μm or less. The average particle diameter can be changed depending on the diameter of the injection port 11a, the shape and length of the flow path, the amount of propellant, etc. The average particle diameter is preferably 25 μm or more. Further, the average particle diameter is preferably 115 μm or less. The basis for setting the average particle diameter will be explained based on the test results described below. The average particle size was measured using a laser light diffraction type particle size measuring device Microtrac Aerotrac LDSA-SPR 1500A (manufactured by Microtrac Bell Co., Ltd.). The particle size of the fly-killing aerosol was measured at a temperature of 25° C. and a spray distance of 30 cm, and the 50% particle size (D50) in the volume integrated distribution was defined as the average particle size.

Further, the particle concentration (CNC) injected from the injection port 11a is set to be 2000 or more. The concentration of particles injected from the injection port 11a is preferably 2500 or more. It is thought that the higher the particle concentration is, the easier it is for the particles to hit the insect bodies and the higher the efficacy, but the practical upper limit of the particle concentration can be 5,000 or less, and 4,500 or less is more preferable. The basis for setting the particle concentration will be explained based on the test results described below. The particle concentration (CNC) was measured using the above-mentioned LDSA-SPR 1500A at a temperature of 25° C. and a spray distance of 30 cm. Note that the particle concentration (CNC) is a concentration index calculated from the intensity of light scattered by particles, and can be measured using the particle size measuring device of the laser light diffraction type.

The aerosol agent for exterminating small flies contains neothiosole, which is liquid paraffin, and a propellant, and is used while being contained in the aerosol container 10 described above. The aerosol agent for killing flies can be composed of a stock solution containing neothiosole and a propellant. The stock solution may contain only neothiozole, or may contain drugs other than neothiozole. The propellant may be liquefied petroleum gas (LPG) only, dimethyl ether (DME) only, or a mixture of liquefied petroleum gas and dimethyl ether. The propellant may be other than liquefied petroleum gas and dimethyl ether, as long as it can achieve the above-mentioned average particle diameter and particle concentration.

The aerosol agent for killing fly flies may contain an insecticide that exhibits an insecticidal effect on fly flies, a repellent that exhibits a repellent action against fly flies, and a synergist that enhances the insecticidal effect. Examples of the insecticide include allethrin, tetramethrin, pralethrin, phenothrin, resmethrin, cyphenothrin, permethrin, cypermethrin, deltamethrin, tralomethrin, cyfluthrin, flamethrin, imiprothrin, etofenprox, fenvalerate, fenpropathrin, cilafluofen, methofluthrin, 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, fenitrothion, tetrachlorobinphos, fenthion, chlorpyrifos, diazinon, etc., carbamate compounds such as propoxer, carbaryl, methoxadiazone, fenobucarb, lufenuron, chlorfluazuron, hexaflumuron, diflubenzuron , cyromazine, chitin formation inhibitors such as 1-(2,6-difluorobenzoyl)-3-[2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]urea, Examples include juvenile hormone-like substances such as pyriproxyfen, methoprene, hydroprene, and phenoxycarb, and N-phenylpyrazole compounds such as fipronil.

Examples of repellents include N,N-diethyl-m-toluamide, limonene, linalool, citronellal, menthol, menthone, hinokitiol, geraniol, eucalyptol, indoxacarb, caran-3,4-diol, 2-( Examples thereof include 2-hydroxyethyl)-1-piperidinecarboxylic acid 1-methylpropyl ester, 3-(Nn-butyl-N-acetyl)aminopropionic acid ethyl ester, and P-menthane-3,8-diol. Note that some insecticides also have a repellent action, and examples of such insecticides include transfluthrin and the like.

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

The aerosol agent for killing flies can be used by directly spraying it on the flies, and in this case, it exhibits an instant fall effect that causes the flies to fall immediately. This is because the neothiosol contained in the aerosol for killing fly flies attaches to the body of the fly, thereby inhibiting the flapping of its wings and making the fly heavier, causing it to fall. Compared to the case where the drop is caused by the action of a chemical such as an insecticide, the dropping effect can be obtained extremely quickly.

In addition, when containing an insecticide or repellent as described above, the aerosol agent for killing fly flies also exhibits the effect of preventing the occurrence of fly flies by spraying it onto garbage or the like, for example. That is, the insecticide or repellent contained in the aerosol agent for killing flies and liquid paraffin can constitute an agent for preventing the occurrence of flies.

Specifically, the details are as follows. That is, by spraying this fly fly prevention agent onto a place where fly flies are likely to occur, such as food waste, eggs and larvae that have already been laid on the food waste can be exterminated. In addition, the insecticide or repellent contained in the fly outbreak preventive agent can kill or repel the flies that come to garbage, thereby preventing them from spawning. Among the ingredients that make up the fly prevention agent, liquid paraffin has low hydrophilicity, so even when used in areas with high moisture content, such as garbage, the insecticides and repellents will not leak out or decompose. It can be suppressed and prevent flies from coming in for a long period of time. In this way, eggs and larvae that have already been laid can be exterminated, and furthermore, spawning can be prevented for a long period of time, so that, for example, it is possible to prevent the occurrence of fruit flies in garbage for a long period of time.

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

(Immediate drop test)
Table 1 shows the composition of the aerosol agent for killing fly flies according to the example.

Table 2 shows the instant drop test results of Examples 1, 2, and 3 and Comparative Examples 1 and 2.

Example 1 is an example in which an aerosol container 10 is used in which the diameter of the injection port 11a of the injection button 11 is 1.5 mm. Example 2 is an example in which an aerosol container 10 is used in which the diameter of the injection port 11a of the injection button 11 is 1.2 mm. Example 3 is an example in which an aerosol container 10 is used in which 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. . Moreover, Comparative Example 2 is an example in which a commercially available hand sprayer was used to spray, and the composition was the same as the stock solution of Examples 1, 2, and 3.

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

In Examples 1, 2, and 3, the average particle diameter 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 a plurality of flying flies were sprayed, the majority of the flies fell immediately. That is, a sufficient instantaneous falling effect was obtained. The test insects are Drosophila melanogaster adults and Butterfly flies adults.

Comparative Example 1 has an average particle diameter of less than 20 μm, specifically less than 10 μm, and a particle concentration of less than 400 μm. In this case, even if the fly was injected toward the flying fly, it hardly fell down and continued flying, so the instant fall effect was extremely weak.

Comparative Example 2 has an average particle diameter of more than 80 μm and a particle concentration of less than 2,000. In this case, even when spraying at flying flies, there were few that fell, and many that continued to fly, so the immediate falling effect was weak.

As shown in the above results, it has become clear that the instant drop effect can be obtained only when the average particle diameter is within a predetermined range and the particle concentration is above a predetermined value. The reason for this is not fully understood, but in addition to the fact that it is thought that a particle concentration above a certain level is necessary for insects that fly around quickly, such as fly flies, particles that are too small to begin with are small. It is thought that this is because particles that are too large are difficult to contact, and the turbulent airflow that occurs around them will blow away the light bodies of the flies, making it impossible for them to come into contact with them.

In this way, the average particle diameter of the particles injected from the injection port 11a is set to be 20 μm or more and 120 μm or less, and the particle concentration is set to be 2000 or more, so compared to the case where particles exceeding this range are injected. , can significantly enhance the immediate falling effect. By setting the average particle diameter to 25 μm or more, the immediate falling effect can be further enhanced, and by setting the average particle diameter to 115 μm or less, the instant falling effect can be further enhanced.

Further, by setting the concentration of particles injected from the injection port 11a to 2,500 or more, the immediate falling effect can be further enhanced. By setting the upper limit of the particle concentration to 5,000 or less, unnecessary increases in concentration are suppressed, and the effect of the aerosol agent for exterminating black flies can be sufficiently obtained without increasing the amount of the aerosol agent for exterminating black flies. By setting the upper limit of the particle concentration to 4,500 or less, the aerosol agent for killing fly flies can be used efficiently.

This immediate fall effect is a physical effect in which neothiozole attaches to the fly's body, preventing it from flapping its wings and making it heavier, causing it to fall. It is alive and may move around. In this regard, the fly extermination aerosols of Examples 1, 2, and 3 contain transfluthrin, an insecticide with an excellent knockdown effect, so that the fallen flies soon stop their activity due to the knockdown effect. and ultimately leads to death.

(Spraying test from a distance)
Next, a spray test from a relatively long distance will be explained. The test method is as follows. Twenty test insects were released into a glass ring with a diameter of 9 cm and a height of 6 cm, and the test chemical was sprayed once from a distance of 150 cm. Then, the mortality rate after 24 hours was calculated. The test insect was an adult Drosophila melanogaster. As test drugs, the above Example 2 and a drug obtained by removing phenothrin from 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 omitted, the mortality rate after 24 hours was 80%. In this way, when sprayed from a relatively long distance, the final lethality can be improved by incorporating phenothrin. It should be noted that when sprayed from this distance, some flies were not able to obtain the immediate falling effect.

In other words, when spraying from a relatively long distance, the spray particles may not adhere sufficiently, so the immediate drop effect is not sufficiently obtained, and the knockdown effect and lethality caused by transfluthrin are also insufficient (comparison above). In the case of Example 3). In this regard, the phenothrin contained in Example 2 is an excellent insecticidal component that has a reliable lethal effect even in small amounts, so even if the spray particles do not sufficiently adhere to the fly, it can ultimately kill the fly. In this way, even when spraying from a long distance where immediate drop is difficult, the final extermination effect can be ensured by incorporating phenothrin.

(Fixing prevention effect confirmation test)
The colonization prevention effect confirmation test is a test to confirm the effect of preventing the occurrence of small flies. To explain the test method, first, the aerosol agent for killing fly flies of Example 4 shown in Table 3 and the aerosol agent of Comparative Example 4 shown in Table 4 were prepared. In both cases, the injection button 11 used was the same as in Example 2 (the diameter of the injection port 11a was 1.2 mm).

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

An orange according to the example in which the aerosol agent for killing fly flies of Example 4 was sprayed once on the cut surface, an orange according to the comparative example in which the aerosol agent in Comparative Example 4 was sprayed once on the cut surface, and an untreated orange. prepared. 14 days after preparing these oranges, the oranges according to the example, the oranges according to the comparative example, and the untreated oranges were placed in a 25 cm x 25 cm acrylic box, and the test insects (yellowfish) were placed in the acrylic box. Two hours later, the number of test insects visiting each orange was confirmed. Furthermore, 21 days after preparing the above oranges, the number of test insects visiting each orange was confirmed in the same manner. Then, the sticking prevention rate (also referred to as fixing prevention rate) was calculated based on the following formula. Note that the number of flies that approach the orange refers to the number of live flies that approach the orange, and does not count the flies that die after coming into contact with the orange.

Approach prevention rate (%) = (Number of non-processed approaches - Number of processed approaches) / Number of non-treated approaches × 100

As is clear from Table 5 and Figure 2, in Example 4 containing kerosene, the approach prevention rate was higher than in Comparative Example 4 containing synthetic alcohol, and the difference especially increased after a long period of time. are doing. This is because kerosene, which is liquid paraffin, has low hydrophilicity, so even when used on areas with a lot of moisture, such as oranges, there is no possibility that the insecticide or repellent (transfluthrin in this test) will leak out. This is because decomposition, etc. can be suppressed, and fly flies can be prevented for a long period of time.

Further, when a similar test was conducted using the aerosol agent for exterminating small flies of Example 2, it was confirmed that the rate of prevention of fly extermination after a long period of time was even higher than that of Example 4. That is, compared to the case of only transfluthrin (Example 4), by further including phenothrin (Example 2), a long-term anti-adherence effect can be obtained. Transfluthrin has a spatial repellent effect and a knockdown effect, so it can be expected to have a particularly high effect on preventing attraction in the early stages, while phenothrin has a high lethal effect even in small amounts, so it is expected to be effective in maintaining the anti-approach effect for a longer period of time. can.

The test insect in the above colonization prevention effect confirmation test was Drosophila melanogaster, but similar results can be obtained with other flies such as the butterfly. Further, although oranges were used in the above-mentioned fixation prevention effect confirmation test, similar results can be obtained even if the above-mentioned test is conducted using garbage other than oranges such as meat, fish, vegetables, etc.

(Hatching prevention effect confirmation test)
The hatching prevention effect confirmation test, like the above test, is a test to confirm the effect of preventing the occurrence of small flies. To explain the test method, first, three oranges were prepared as colonizers, and each orange was left standing in a room where fly flies breed for three days to allow the fly flies to lay eggs. Next, one of the three spawned oranges was sprayed once with the aerosol agent for exterminating small flies of Example 2, another one was sprayed once with the aerosol agent for exterminating minor flies of Example 4, and the remaining one One was left untreated. Each orange was stored for 14 days, and the presence or absence of adult fly flies was confirmed.

As a result, the untreated orange had more than 200 flies, whereas the orange according to Example 2 had 0 flies, and the orange according to Example 4 had 5 flies. That is, by treating the source of fly flies with an aerosol agent for killing fly flies, eggs that have already been laid can be prevented from hatching, or larvae that have already hatched can be exterminated.

As described above, by treating the source of fly flies with an aerosol agent for killing fly flies, 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 adults from approaching for a long period of time, thereby preventing fly flies from laying eggs at the source. With the above, it is possible to prevent the occurrence of black flies over a long period of time.

(Operations and effects of embodiments)
As explained above, according to this embodiment, when an aerosol agent for exterminating flies is injected toward small and fast-moving pests such as butterflies and fruit flies while they are flying, the particles are This makes it easier for the particles to adhere to the flies, and the number of particles that attach to the flies also increases, resulting in an immediate falling effect. This eliminates the need for non-volatile components such as edible oil, making it easier to use indoors, for example. Further, by using the fixed amount injection valve 12, it is possible to spray only the amount necessary to drop the flies present at the spot without waste.

In addition, if the sprayed particles do not hit the insect body, the immediate fall effect may not be sufficient, but even in this case, we use highly lethal agents such as phenothrin. , it is possible to finally kill the insect, and a more reliable extermination effect can be obtained.

Furthermore, by incorporating a drug with a high knockdown effect such as transfluthrin, it is possible to achieve a high extermination effect because the flies that fall immediately when the particles hit the target are immediately knocked down.

In addition, since the liquid paraffin contained in the aerosol agent for killing fly flies is low in hydrophilicity, it is possible to prevent fly flies for a long period of time even when it is used in a place with a lot of moisture, such as garbage. Moreover, at this time, for example, eggs and larvae that have already been laid on the garbage can be exterminated, so that it is possible to prevent the occurrence of fruit flies on the garbage for a long period of time.

As described above, by blending transfluthrin, phenothrin, and kerosene into an aerosol agent with a predetermined particle size, it is possible to provide an aerosol that is excellent in both direct spraying and prevention effects against fly flies through objective treatment.

Furthermore, since particle diameters in the above range are likely to spread, for example, in indoor spaces, the aerosol product 1 using the metered injection valve 12 can be used as a space treatment agent to treat the entire indoor space with one spray treatment. It is also possible to use That is, in this case, by spraying the fly exterminating aerosol agent once toward the indoor space, the spray particles containing transfluthrin and phenothrin are spread throughout the space, making it possible to create a space free of fly flies.

Incidentally, there have been conventional spatial treatment agents for fly flies that use ethanol as a solvent. In this regard, since the present invention uses kerosene as a solvent, the dispersibility is inferior to that of ethanol formulations, which have high volatility. Therefore, in this embodiment, the metered injection valve 12 is used to make it possible to inject 1 ml of aerosol agent, which has a larger capacity than the conventional one. By using such a large-capacity fixed-rate injection valve 12, the contents are sprayed vigorously at once, so that the dispersibility is improved. As a result, even in this embodiment using kerosene as a solvent, it is possible to achieve a diffusivity equivalent to or higher than that of a conventional metered-dose spray agent using ethanol as a solvent.

The embodiments described above are merely illustrative in all respects and should not be interpreted in a limiting manner. Furthermore, all modifications and changes that come within the scope of equivalents of the claims are intended to be within the scope of the present invention.

The fly exterminating aerosol agent can be an aerosol agent for garbage that is sprayed directly onto garbage indoors or outdoors, or it can be an aerosol agent for garbage containers that is sprayed directly into a container for storing garbage. It can also be sprayed directly into the kitchen sink, trash can, etc. These are sources of flies, but they can also be used by spraying them into indoor spaces such as the kitchen, dining room, living room, etc. It can also be used against flying flies in outdoor spaces.

As explained above, the present invention can be used to exterminate, for example, Drosophila melanogaster and butterflies.
