Thereby, insects such as cockroaches are completely killed while keeping tableware, etc., in an intact state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insecticidal method capable of almost completely erasing insects such as cockroaches inhabiting indoors of restaurants, restaurants and the like, and an apparatus used for the method.

[0002]

2. Description of the Related Art Conventionally, as a cockroach exterminating method, there are known a method of attracting cockroaches into a container made of paper and the like, a method of exterminating the cockroaches by capturing them with an adhesive in the container, and a method of spraying a drug. Was there. However, with the former method, it was practically impossible to completely eliminate the cockroaches because the number of cockroaches that could be captured in one container was limited, and with the latter method, dishware, food Since other instruments are contaminated with chemicals, there is a problem that tableware and the like have to be cleaned up before the treatment or washed after the treatment.

Particularly, in restaurants and restaurants,
Since the cockroaches prefer to store a large amount of bait, if many cockroaches appear and disappear, and small cockroaches mix in the stored materials such as vegetables, they may accidentally mix in the dishes, Although there has been a strong demand for a method to eradicate the cockroaches, it was impossible to completely eradicate the cockroaches even with the method of spraying the drug, because most of the cockroaches lie in places where the drug does not hit.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and can kill insects such as cockroaches almost completely while being able to kill insects without any trouble even when the tableware etc. is left as it is. It is an object of the present invention to provide an insecticidal method that can be performed and an apparatus used for the method.

[0005]

Means for Solving the Problems As a result of earnest research to achieve the above-mentioned object, the inventors of the present invention have noticed that air is uniformly agitated and mixed by an air conditioner, and an insecticide is aired by the same principle as that of an air conditioner. The present invention has been found to be able to eradicate cockroaches and the like extremely effectively because the drug spreads to the location where the cockroaches and the like are lurking in a very short time by mixing them substantially uniformly.

That is, according to the present invention, a container filled with a gaseous insecticide is housed in a housing having an air inlet and an air outlet, and air is passed through the housing while ejecting the gaseous insecticide. A mixed air of the gaseous insecticide and air is formed, and the mixed air is ejected from the inside of the housing into the room to circulate the room air. Further, the insecticidal device of the present invention accommodates, in a housing having an air inlet and an air blower for blowing the sucked air, a rotary blade that is rotated by a motor to blow air and a container filled with a gaseous insecticide. And a storage unit for storing the gas, and the mixed air of the indoor air and the gaseous insecticide is circulated in the room by the rotary vanes.

The gaseous insecticide used in the present invention is not particularly limited as long as it becomes a gas or a mist at room temperature and forms a mixed gas with air. Examples of such substances include dimethyl dichlorovinylphosphate and ethyl chloride, but for the purpose of controlling cockroaches,
Dimethyldichlorovinylphosphate is particularly preferred. Dichlorodivinylphosphate is a dichlorvos (DDV
P), which is commercially available as an insecticide, is filled in a cylinder with a non-combustible gas such as CFC or carbon dioxide as a carrier gas, and a commercially available product may be used. Similarly for ethyl chloride, together with nonflammable gas,
It is good to use by filling the inside of the cylinder.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a sectional view showing an insecticidal device of the present invention,
Rotating blades 3 which are rotated by a motor 2 and suck air and blow it below a housing 1 formed in a quadrangular cylinder.
A cylinder 4 filled with insecticide is housed in a cylinder container 5 above the rotary blade 3. At the upper end opening of the housing 1, slender plate-like fins 6 are rotatably fixed to the inner wall of the housing 1 by pivotally fixing rod-shaped parts at both ends, and blow air according to the size of the room or the like. You can choose the orientation. Air is designed to flow into the apparatus through the opening at the bottom of the housing 1 and the vent hole 7 formed in the outer periphery of the lower portion of the housing 1 as indicated by the arrow.

The air flowing into the apparatus is blown upward as shown by the arrow and forms a mixed gas with the gaseous pesticide ejected from the cylinder 4, and the mixed gas is guided by the fins 6 to the inside of the room. Is squirted out, circulates in the room, and flows into the device again. The cylinder container 5 is fixed on a net-shaped shelf 8 fixed to the housing 1. Reference numeral 9 in the drawing denotes a door for loading and unloading the cylinder, which can be opened and closed by a hinge 10.

When the device shown in FIG. 1 is applied to a restaurant having a counter, it becomes difficult for the mixed gas to circulate in the counter, so that the effects of the present invention cannot be sufficiently exerted. FIG. 2 is a perspective view showing an example of the insecticidal device of the present invention used in such a case, in which a rotary blade 3 which is rotated by a motor is internally provided in a cylindrical housing 1 having a wire net 11 stretched at one end. The flexible tube 12 is fitted and connected to the other end of the cylindrical housing 1,
A fin 6 is rotatably fixed to the tip of the container 2, and a cylinder 4 is housed in a container 5 fixed to the tip of the housing 1. Using the above device, only the flexible pipe 12 is put in the counter, and if the mixed gas of the pesticide and air is jetted from the tip of the flexible pipe 12, the air is evenly distributed inside and outside the counter. Circulate.
In this case, the device shown in FIG. 1 may be used together if necessary.

Using the apparatus shown in FIG. 1, 300 m ²
The inside of the cafeteria was slaughtered. While rotating the rotary vane 3, the cylinder 4 containing 9.7% of dichlorvos in the carrier gas of CFC was opened, and a gas having an internal capacity of 50 g was added to 2 to 3 parts.
The mixture was mixed with air for a minute, and the mixture of dichlorvos and air was ejected from the upper end of the device while being guided by the fins 6, and the operation of the device was continued for 1 hour to circulate the mixed gas in the cafeteria.

As a result, it was confirmed that since dichlorvos having a substantially uniform concentration circulated in the cafeteria and the gaps, about 1500 cockroaches came out in the cafeteria and were killed. One week before the above test, 5 cans of balsan commercially available were used to exterminate the cockroaches in the same dining room as above, and it was confirmed that about 300 cockroaches had been killed.
If you have removed the cockroaches with Balsan as described above,
It was observed that cockroaches appeared and disappeared again after 1 day, but according to the method of the present invention, no appearance of cockroaches was observed even after 10 days. This confirmed that the method of the present invention was able to almost completely eliminate cockroaches. It was also confirmed that about 80% of the bacteria in the cafeteria were killed by the method of the present invention. This is unexpected because dichlorvos has not been used as a fungicide.

[0013]

According to the method of the present invention, the cockroach-controlling agent and the air are sufficiently stirred and mixed and circulate in the room according to the same principle as that of the air conditioner, so that the cockroach-controlling agent also enters the place where the cockroach is lurking. , It seems that an unprecedented excellent effect of eradicating cockroaches was achieved.

[0014]

As described above, according to the present invention, the insecticide is mixed with air to control insects such as cockroaches in the room according to the same principle as that of the air conditioner. Since it will enter the place where it is present, not only can a great insecticidal effect be achieved, but bacteria in the cafeteria can also be killed.If a gas insecticide at room temperature is used, it can be used for tableware, food, etc. Since there is no residual adhesion, there is no need to clean up tableware or the like when disinfecting or to wash the tableware or the like after disinfection, which is a remarkable effect not seen at all in this conventional insecticidal method.
