Description

  The present invention relates to a bee control aerosol that prevents a bee from approaching an object, and a bee control method using the same.

  In Japan, about 3000 types of bees are known, and among them, about 20 types of bees with a strong bite property are said. In recent years, residential land has been developed in hilly areas around cities, and as a result, human damage caused by bees with strong bites is increasing. For this reason, there is an increasing demand for extinguishing bees not only in mountainous areas but also in urban areas. In order to control bees, methods of knocking down and killing them by directly acting on the bees are widely used, and as a product for that purpose, the control of bees that consists of an aerosol containing an insecticidal component sealed in a pressure-resistant container Aerosols are commercially available.

  Conventionally, there has been an aerosol for bee control containing 2-methyl-4-oxo-3- (2-propynyl) cyclopent-2-enyl chrysanthemate as an active ingredient (for example, see Patent Document 1). . According to Patent Document 1, 2-methyl-4-oxo-3- (2-propynyl) cyclopent-2-enyl chrysanthemate is dissolved in kerosene and filled into an aerosol can together with LPG as a propellant. It constitutes an aerosol for bee control.

  Moreover, there existed what prepared the composition containing metofluthrin and tetramethrin as an active ingredient in the aerosol agent (for example, refer patent document 2). According to Patent Document 2, the above composition is dissolved in a saturated hydrocarbon solvent and filled with an LPG as a propellant into an aerosol can to constitute a bee-controlling aerosol.

  Bees are insects that form a nest at the entrance, under the eaves, or on the veranda of a house and are active in a wide range. Bees have a habit of sticking to a place once they have built a nest and trying to build a nest in the same place once the nest is removed. Therefore, when the bees are exterminated, it is not sufficient to spray the aerosol agent directly on the flying bees to knock down and kill them, and it is important to prevent the bees from nesting.

  In this regard, the aerosol of Patent Document 1 or Patent Document 2 is an agent that attaches an aerosol agent to a bee and knocks it down and kills it. However, in a product that was developed to prevent bee nesting activity, Absent. Therefore, even if the aerosol of Patent Document 1 or Patent Document 2 is sprayed toward a place where bees are likely to form a nest and the aerosol agent is applied, the bees may actually come in contact with the insecticidal component contained in the aerosol agent. Without it, the bees cannot be knocked down and killed. In addition, if bees build a nest avoiding the spot where insecticidal components are attached, a large amount of bees will eventually be generated, and it may be difficult to remove them unless they are specialists.

  The present invention has been made in view of the above problems, and in addition to knocking down and killing bees, bees capable of fundamentally controlling bees by preventing bee nesting activity. An object of the present invention is to provide a control aerosol and a bee control method using the bee control aerosol.

An aerosol for bee control that prevents a bee from approaching an object,
In a pressure-resistant container, encapsulated an aerosol containing a non-volatile pyrethroid insecticide component, a bee repellent component, an organic solvent, and a propellant,
When the aerosol spray particles sprayed toward the object adhere to the object, the bee repellent component is prepared to be volatilized around the object from the spray particles. .

  According to the bee-controlling aerosol of this configuration, an aerosol agent containing a non-volatile pyrethroid insecticide component, a bee repellent component, an organic solvent, and a propellant is used. The non-volatile pyrethroid insecticide and bee repellent component are enclosed in a pressure vessel in a dissolved state (aerosol solution) in an organic solvent, so both components are integrated with the organic solvent immediately after injection. Released into the atmosphere in particulate form. And when the spray particle | grains of an aerosol agent adhere to a target object (bee or building), since the non-volatile pyrethroid type insecticidal component contained in the said spray particle is hard to volatilize, the state adhering to the target object is maintained. Therefore, the non-volatile pyrethroid insecticidal component attached to the bee can knock down and kill the bee quickly, and the non-volatile pyrethroid insecticidal component attached to the building Stopping (contacting) can avoid or knock down the bees and even kill them. On the other hand, the bee repellent fragrance component contained in the spray particles of the aerosol agent has volatility unique to the fragrance. Therefore, when the spray particles adhere to the object, they gradually evaporate into the surrounding atmosphere. Therefore, the bee repellent fragrance component adhering to the object volatilizes with time and drifts around the object, and exhibits a repelling action that does not attract bees over a long period of time. As described above, by using the non-volatile pyrethroid insecticide component and the bee repellent fragrance component together as an aerosol agent, not only is the bee knocked down and killed directly, but also a repellent effect that does not attract the bee is exhibited at the same time.

In the bee control aerosol according to the present invention,
After the spray particles adhere to the object, the period during which the bee repellent component is volatilized from the spray particles is set to be 1 to 30% of the effective period of the hardly volatile pyrethroid insecticide component. Preferably it is.

  According to the aerosol for bee control in this configuration, the bee repellent component evaporates from the aerosol spray particles over a certain period during the effective period of the non-volatile pyrethroid insecticide component, so the target is immediately after using the aerosol. The repellent effect permeates around the object. Therefore, the bees can be reliably controlled at the initial stage when the bees start the nesting activity.

In the bee control aerosol according to the present invention,
The organic solvent is preferably normal paraffin or isoparaffin.

  According to the bee control aerosol of this configuration, since the above-mentioned appropriate organic solvent is used, the spray particles of the aerosol agent can be reliably attached to the object, and the bee repellent fragrance component is volatilized. The property is also good.

In the bee control aerosol according to the present invention,
The repellent effect sustaining component is preferably at least one selected from the group consisting of isopropyl myristate, butyl myristate, hexyl laurate, and isopropyl palmitate.

Hereinafter, each component of the aerosol agent used for the aerosol for bee control of the present invention will be described. However, the present invention is not intended to be limited to the configurations described in the embodiments and drawings described below.

[Non-volatile pyrethroid insecticide]
The non-volatile pyrethroid insecticidal component that is one of the main components of the aerosol stock solution is a pyrethroid insecticidal component having a vapor pressure of less than 1 × 10 ⁻⁵ mmHg at 25 ° C.

Further, when there are optical isomers and geometric isomers in the molecular structure of the bee repellent fragrance component, these are also included in the present invention.

[Continuous component of repellent effect]
In order to maintain the repellent effect of the bee repellent fragrance component, the aerosol stock solution can contain a repellent effect continuous component. As the repellent effect sustained component, higher fatty acid esters having a total carbon number of 13 to 20, preferably 16 to 20, are used, and examples thereof include isopropyl myristate, butyl myristate, hexyl laurate, and isopropyl palmitate.

Ingredients will continue to evaporate into the atmosphere in a well-balanced manner over a long period of time. In addition, the above-mentioned repelling effect continuous component is not limited to the use alone, and two or more kinds may be used in combination.

〔Organic solvent〕
The aerosol stock solution contains an organic solvent capable of dissolving a non-volatile pyrethroid insecticide component, a bee repellent fragrance component, and a repellent effect sustaining component used as necessary. By dissolving each of the above components in an organic solvent, an aerosol stock solution having both an insecticidal action and a repellent action against bees is prepared. Since the characteristics of the organic solvent affect the formation of spray particles when the aerosol agent is sprayed, those adjusted to an appropriate viscosity are used. The viscosity of the organic solvent is preferably less than 10 mPa · s at 20 ° C., more preferably less than 5 mPa · s.

In addition, the above-mentioned organic solvent is not limited to the use by itself, You may use it in combination of 2 or more types.

[Propellant]
As the propellant, in order to vigorously inject the aerosol stock solution into particles, a gaseous one is used at normal temperature and pressure. In addition, the propellant is required to have stability that does not alter the non-volatile pyrethroid insecticide component, the bee repellent fragrance component, the repellent effect sustained component, and the organic solvent in the pressure vessel. Examples of such a propellant include liquefied petroleum gas (LPG), dimethyl ether (DME), nitrogen gas, carbon dioxide gas, nitrous oxide gas, and compressed air. Of these, LPG and nitrogen gas, which are easily available and easy to handle, are preferably used. In addition, the above-mentioned propellant is not limited to the use by itself, You may use it in combination of 2 or more types.

[Other ingredients]

Examples include aromatic components such as ethyl alcohol, amylcinnamic aldehyde, cuminaldehyde, and benzyl acetate, and a fragrance component containing green leaf alcohol and green leaf aldehyde called “green fragrance”.

  Moreover, in addition to the above-mentioned non-volatile pyrethroid insecticide component, other insecticide components can be added to the aerosol stock solution as long as the bee control effect is not impaired. Illustrative examples include volatile or weakly volatile pyrethroid insecticide components such as empentrin, transfluthrin, metfluthrin, profluthrin, terrareslin, allethrin, praletrin, pyrethrin, neonicotinoid insecticide components such as dinotefuran, and organic phosphorus such as fenitrothion. Carbamate insecticide components such as system insecticide components and propoxurs. In addition, praretrin, imiprothrin and the like can be blended as a fast-acting insecticidal component in order to directly act on bees and beehives.

[Aerosol formulation]
Each of the above-mentioned components used in the aerosol agent is prepared so as to be optimally blended in the pressure resistant container in order to exhibit the insecticidal effect and the repellent effect against bees simultaneously and in a balanced manner. The content of the non-volatile pyrethroid insecticide component is the content in the aerosol stock solution (non-volatile pyrethroid insecticide component, bee repellent component, (if necessary) repellent effect sustaining component, and organic solvent mixture) 0.01 to 3.0 w / v%, preferably 0.1 to 1.0 w / v%. When the amount of the non-volatile pyrethroid insecticidal component is less than 0.01 w / v%, the insecticidal effect of bees cannot be sufficiently obtained, and even if it exceeds 3.0 w / v%, the insecticidal effect is hardly changed. It becomes uneconomical. The compounding amount of the bee repellent fragrance component is 0.01 to 5.0 w / v%, preferably 0.1 to 2.0 w / v% as the content in the aerosol stock solution. When the amount of the bee repellent perfume component is less than 0.01 w / v%, the effect of bee repellent is not sufficiently obtained. When the amount is greater than 5.0 w / v%, the relatively non-volatile pyrethroid insecticidal component is included. Since the amount is reduced, there is a possibility that the insecticidal effect by the non-volatile pyrethroid insecticidal component may not be sufficiently obtained when the effect of the bee repellent fragrance component disappears. The compounding quantity of a repellent effect continuous component is 2.0-50 w / v% as a content in an aerosol stock solution, Preferably it is 5.0-30 w / v%. When the compounding amount of the repellent effect sustaining component is less than 2.0 w / v%, the effect is not so much obtained, and even if it exceeds 50 w / v%, further extension of the duration of the repellent effect cannot be expected, which is not economical. . In addition, the ratio (x / y) of the blending amount (x) of the bee repellent fragrance component and the blending amount (y) of the repellent effect sustaining component is preferably adjusted to about 0.005 to 0.5, and more preferably. It is adjusted to about 0.01 to 0.2. By adjusting the blending amount of the bee repellent component and the repellent effect sustaining component within the range of the above ratio (x / y), the repellent effect by the bee repellent component can be realized quickly, and further, the repellent effect can be realized over a long period of time. Can be sustained. The compounding amount of the organic solvent is 50 to 97 w / v%, preferably 60 to 95 w / v% as the content in the aerosol stock solution. When the amount of organic solvent is less than 50 w / v%, spray particles are difficult to adhere to the target, so the insecticidal effect and repellent effect do not last long. In addition, since the volatilization of the bee repellent fragrance component is promoted, it is difficult to obtain the sustainability of the repellent effect. The propellant is adjusted so that the volume ratio (a / b) of the aerosol stock solution (a) and the propellant (b) is 40/60 to 80/20. When the volume ratio (a / b) is smaller than 40/60, the propellant becomes excessive, so that the relative amount of the aerosol stock solution in the pressure vessel is reduced, and a single bee-controlling aerosol is used. In some cases, the spraying process cannot be performed on all of the regions. When the volume ratio (a / b) is greater than 80/20, the propellant is insufficient, and there is a possibility that the spray particles of the aerosol agent do not reach the object. When the volume ratio (a / b) is adjusted to the appropriate range, the internal pressure of the aerosol agent in the pressure vessel is 0.25 to 0.70 MPa (25 ° C.).

[Three-dimensional control effect of aerosols]
The bee-controlling aerosol of the present invention constituted by sealing the aerosol agent prepared as described above in a pressure resistant container has an insecticidal effect and a repellent effect which are further evolved from conventional aerosols. FIG. 1 is a model diagram showing the behavior of spray particles 10 of an aerosol agent when the bee-controlling aerosol 100 of the present invention is sprayed toward an object (building B). As shown in FIG. 1 (a), the non-volatile pyrethroid insecticidal component 1 and the bee repellent component 2 which are characteristic components in the aerosol 100 for bee control of the present invention are dissolved in the organic solvent 3 before injection. The aerosol stock solution 4 is enclosed in the pressure vessel 6 together with the propellant 5. As shown in FIG. 1A, the user prepares for injection by directing the bee-controlling aerosol 100 toward the building B that is the target (injection preparation step). Although not shown, when the bee A has already arrived in the vicinity of the building B, the bee-controlling aerosol 100 may be directly directed to the bee A to prepare for injection. Next, as shown in FIG. 1B, the user injects the aerosol agent with the bee-controlling aerosol 100 directed toward the building B. In this case, the spray force of the bee control aerosol 100 is preferably set to be 25 gf or more at 25 ° C. at a position 20 cm ahead of the spray port of the bee control aerosol 100. Is preferably set so that the aerosol stock solution adhering to the object (building B) is 10 to 250 mL / m ² . When the aerosol agent is injected, immediately after the injection, the non-volatile pyrethroid insecticide component 1 and the bee repellent component 2 are integrated with the organic solvent 3 as shown in the enlarged portion in FIG. As a result, the particles are released into the atmosphere in the form of particles, and spray particles 10 are formed in which droplets of the organic solvent 3 contain the non-volatile pyrethroid insecticidal component 1 and the bee repellent component 2. The size of the spray particles 10 is set to 20 to 70 μm, preferably 30 to 60 μm, as a volume integrated 10% particle diameter at 25 ° C. If the 10% particle diameter is less than 20 μm, the spray particles 10 are likely to be scattered and the adhesion efficiency to the building B is deteriorated. If the 10% particle diameter exceeds 70 μm, the reach of the spray particles 10 may be shortened. is there. Eventually, as shown in FIG. 1 (c), the spray particles 10 adhere to the bee A1 to be removed or the building B to be treated (injection treatment step). Then, since the hardly volatile pyrethroid insecticidal component 1 contained in the spray particles 10 is difficult to volatilize, the state of adhering to the bees A1 and the building B is maintained even after a certain amount of time has passed. Therefore, as shown in FIG. 1D, the non-volatile pyrethroid insecticidal component 1 attached to the bee A1 flying around the building B quickly knocks down and kills the bee A1. Moreover, about the non-volatile pyrethroid type insecticidal component 1 adhering to the building B, when another bee A2 that has come from the vicinity of the building B accidentally stops at the adhering site, the bee A2 is non-volatile. The pyrethroid insecticidal component 1 can be contacted and repelled or knocked down, and can also be killed. On the other hand, since the bee repellent fragrance component 2 contained in the spray particles 10 has volatility unique to the fragrance, when the spray particles 10 adhere to the building B, the bee repellent fragrance component 2 gradually evaporates into the surrounding atmosphere. Therefore, as shown in FIG. 1 (e), the bee repellent fragrance component 2 contained in the spray particles 10 attached to the building B is volatilized over time and drifts around the building B, and the nest from a remote location. It exerts a repellent action that keeps the bee A3 who is asked to make the

  Thus, when the aerosol 100 for bee prevention is sprayed toward the building B {FIGS. 1 (a) to (b)} and the spray particles 10 of the aerosol agent are adhered, {FIGS. 1 (c) to (d) }, A repellent barrier C by the bee repellent component 2 is formed three-dimensionally around the area where the volatile pyrethroid insecticide component 1 is attached {FIG. 1 (e)}, and powerful bee control The effect will be demonstrated. Although the repellent barrier C continues to be formed over a period in which the bee repellent fragrance component 2 is volatilized, a period in which the bee repellent fragrance component 2 is volatilized from the spray particles 10 after the spray particles 10 adhere to the building B is preferable. Is set to 1 to 30% of the effective period of the non-volatile pyrethroid insecticide component 1. Generally, the effective period (use period) of the non-volatile pyrethroid insecticide component 1 outdoors is set to about 1 to 3 months. Therefore, it is preferable that the period during which the bee repellent fragrance component 2 evaporates is set to about 8 hours to 30 days. The ratio of the volatilization period of the bee repellent component 2 to the effective period of the non-volatile pyrethroid insecticide component 1 can be adjusted by devising a combination of both components or by selecting the organic solvent 3 that dissolves both components. For example, if the non-volatile pyrethroid insecticidal component 1 and bee repellent fragrance component 2 usable in the present invention are adjusted to the above-mentioned preferable blending amounts, the bee repellent flavor component 2 for the effective period of the non-volatile pyrethroid insecticidal component 1 is adjusted. The ratio of the volatilization period is generally in the range of 1-30%. The bee-control aerosol 100 in which the effective period of the non-volatile pyrethroid-based insecticidal component 1 and the bee-repellent perfume component 2 is appropriately set has a repellent barrier C around the building B immediately after its use. Since the repellent effect is exerted, the bee can be surely controlled particularly at the initial stage when the bee starts nesting activity. Therefore, by using the bee control aerosol 100 of the present invention, bee approach and nesting activity are prevented, and fundamental bee control is possible.

<Preparation of bee control aerosol>
In order to confirm the performance of the aerosol for bee control according to the present invention, a control effect confirmation test was performed on multiple types of bees. An aerosol stock solution of bee control aerosol was prepared by the following formulation. As a non-volatile pyrethroid insecticidal component, 1.3 g (0.37 w / v%) cyfluthrin, and 0.25 g (0.071 w / v%) d-T80-phthalthrin, and a mixed fragrance α 0.8 g as a bee repellent fragrance component (0.22 w / v%), 20 g (5.7 w / v%) isopropyl myristate as a repellent effect sustained component, and normal paraffin (neothiozole) as an organic solvent as a balance (balance), and 350 mL of aerosol stock solution Prepared. The mixed fragrance α of the bee repellent fragrance component is a mixture composed of a plurality of types of fragrance components, and the blending amount thereof is as shown in Table 1 below.

  The aerosol stock solution (a) and the propellant (b) are prepared by sealing the aerosol stock solution prepared as described above together with a propellant (containing 150 mL of LPG gas as the main agent and nitrogen gas 0.60 MPa for adjusting the internal pressure) in a pressure-resistant container. A total amount of 500 mL of a bee-controlling aerosol having a volume ratio (a / b) of 70/30 was prepared, and this was designated as Example 1. The spray force of the aerosol for controlling the bees of Example 1 is 46 gf at 25 ° C. at a position 20 cm in front of the spray port, and the size of the spray particles of the aerosol agent is 41 μm as a volume integrated 10% particle diameter at 25 ° C. there were.

<Effect confirmation test 1 of bee control aerosol>
The bee-controlling aerosol of Example 1 was sprayed at the initial stage nest of the hornet wasp that was made under the eaves (width 2m x depth 0.5m) of a detached wooden house as an object. The processing amount of the aerosol agent at this time was about 200 mL as an aerosol stock solution. Therefore, the adhesion amount of the non-volatile pyrethroid insecticide component on the object is about 0.8 g / m ² , the adhesion amount of the bee repellent fragrance component is about 0.5 g / m ² , and the adhesion amount of the repellent effect sustained component is about 11 .6g / ^{m 2} and each is estimated.

  When the bee control aerosol of Example 1 was sprayed, the hornets that lived in and around the nest immediately died. Also, the hornets that escaped from the extermination did not return to their nests. As described above, when the bee control aerosol of Example 1 was used for the hornet wasp, it was revealed that the hornet bee exhibits a certain repellent behavior and can be knocked down and lethal. And in the nest treated with the aerosol agent and the surrounding area, no new nesting activity by the hornet wasp was confirmed for more than two months.

<Effect confirmation test 2 of bee control aerosol>
The inventors observed various behaviors of various bees. As a result, when repellent and insecticidal components such as pyrethroids are given to bees, the bees mainly (A) rub the antennae and abdomen with their legs and dress them, (B) 10 seconds on the spot. It has been newly discovered that it exhibits any one of the following three behavior patterns: behavior that keeps flapping to the extent, and (C) behavior to fly. Then, in order to examine the effect of the bee control aerosol of the present invention in more detail through the observation of the bee behavior pattern (repelling behavior), an effect confirmation test 2 described below was performed.

First, the aerosol for bee control of Example 1 was sprayed onto a glass plate to apply an aerosol stock solution on one glass surface of the glass plate, and this was naturally dried. The coating amount of the aerosol stock solution on the glass surface was 50 mL / m ² . Next, put a phthalmon wasp into a petri dish with a diameter of 9 cm, place it on the petri dish with the aerosol solution on the glass plate facing down, and seal the phthalmon wasp between the petri dish and the glass plate. did. In this state, it was left for 1 hour to forcibly expose the non-volatile pyrethroid insecticidal component and the bee repellent component contained in the aerosol stock solution to phthalmon wasps. During the exposure period, the behavior of the staghorn wasp was observed, and then the stag bee was transferred to a clean plastic cup, and the mortality of the stag bee after 24 hours was determined. For comparison, a mixed fragrance α 0.8 g and a normal paraffin (neothiozole) residue were mixed to prepare an aerosol stock solution (Comparative Example 1) adjusted to 350 mL, cyfluthrin 1.3 g, d-T80-phthalthrin 0.25 g, Using an aerosol stock solution (Comparative Example 2) prepared by mixing 20 g of isopropyl myristate and a normal paraffin (neothiozole) residue to 350 mL, and an aerosol stock solution (Comparative Example 3) consisting of 350 mL of normal paraffin (neothiozole), respectively. An aerosol was produced and the same effect confirmation test as in Example 1 was performed. Table 1 shows the formulation of the aerosols of Example 1 and Comparative Examples 1 to 3.

  Table 3 shows the repellent behavior of phthalmon wasps observed in the petri dish during the aerosol exposure period, and the mortality of phthalmon wasps after 24 hours.

  When the bee control aerosol of Example 1 was used, all the behavioral patterns (A), (B), and (C) were clearly observed. In particular, the behavior pattern of (C) is the behavior most hated by phthalmon wasps, and this is particularly effective due to the residual effect of cyfluthrin contained in the aerosol for bee control and the repellent property of the mixed fragrance α. It is thought that he is playing. Further, the mortality of phthalmon wasps after 24 hours was 100%. On the other hand, when the aerosol of Comparative Example 1 was used, the behavior patterns of (A) and (B) were observed, but the behavior pattern of (C) was slight. And the mortality of phthalmon wasps after 24 hours was 0%, and it was not possible to kill them. When the aerosol of Comparative Example 2 was used, although the behavior patterns of (A) and (B) were slightly observed, the behavior pattern of (C) was not observed. However, since the comparative example 2 contains the same amount of the non-volatile pyrethroid insecticide as in Example 1, the lethality of phthalmon wasps after 24 hours was 100%. When the aerosol of Comparative Example 3 was used, none of the behavior patterns (A), (B), and (C) were observed. Moreover, the mortality of phthalmon wasps after 24 hours was 0%, and it was not possible to kill them.

<Effect confirmation test 3 of bee control aerosol>
Since the bees are aware of the location of their nest, even if the nest is removed, it can return to the location where the original nest existed. And it has the property of nesting again or staying there. Such bees are called “return bees” and are very excited because they have lost their nests, which may increase their aggressiveness. Therefore, the present inventors conducted an effect confirmation test 3 described below in order to confirm the immediate effect of the bee-controlling aerosol of the present invention.

Examples of multiple formed phthalmon wasps nests were removed after the queen was flying away from the nest, or when the number of worker bees in the nest decreased, and the nest was removed. 1 wasp aerosol and the aerosols of Comparative Examples 1 to 3 were sprayed and treated as an aerosol stock solution at 100 mL / m ² . One hour after the injection treatment, the number of phthalmon wasps that came to the place where the nest existed was counted, and further, one week later, it was observed whether the bees would nest again. This effect confirmation test 3 was conducted for each of three beehives.

  As a result, when the bee-controlling aerosol of Example 1 was used, a return bee within 1 hour was not confirmed, and nesting after one week was not confirmed. When the aerosol of Comparative Example 1 was used, the number of returned bees within 1 hour was 0 out of 3 sites, but nesting was confirmed at 1 site relative to the original nest after 1 week. When the aerosol of Comparative Example 2 was used, return wasps were confirmed at two locations within 1 hour. However, no nesting was observed in any one week. When the aerosol of Comparative Example 3 was used, it returned to all three places within 1 hour, and wasps were confirmed. One week later, nesting was confirmed in 2 out of 3 sites relative to the original nest.

  Thus, the bee-controlling aerosol of the present invention was effective not only in knocking down and killing bees quickly, but also in preventing bee nesting activity over a long period of time. Therefore, by repeatedly using the aerosol for controlling the bees of the present invention at appropriate intervals, it becomes possible to prevent the bees from approaching and nesting and to fundamentally control the bees.

  The aerosol for bee control and the bee control method of the present invention are used for preventing the bees from approaching the entrance, under the eaves, and the veranda of a house, but include mosquitoes, chironomids, and fly flies. The present invention can also be applied to uses for controlling flying insect pests and cockroaches such as cockroaches, ants, centipedes, and spiders.
