Abstract

PROBLEM TO BE SOLVED: To provide a method for exterminating small animals, which has a large and persistent effect for exterminating the small animals, does not pollute environments, and is harmless. SOLUTION: This method for exterminating small animals comprises charging ozone gas generated from an ozone generator 5 into a small animal-infesting space and maintaining the ozone gas in a prescribed concentration. In addition, the method for more effectively exterminating the small animals comprises synchronously charging the ozone gas and lighting a UV light lamp 6 to recognize and memorize the relation in the small animals, and then lighting the UV light lamp.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for controlling harmful rats and other small animals using ozone gas. The present invention also relates to a method for more effectively exterminating small animals by using both supply of ozone gas and lighting of an ultraviolet lamp.

[0002]

2. Description of the Related Art Rats inhabit dark places such as ordinary houses, warehouses, and culverts in drains, and appear and disappear at night, eating food, biting surrounding items, and polluting the environment. A harmful animal that damages. Home kitchens, restaurants, food production factories, etc. must always be kept in good hygiene. In these environments, there is a large amount of foodstuffs to feed, so that rats and the like can settle in and cause various harms such as eating foods, wooden boxes, pillars, and the like, and polluting those sites with food waste and feces.

Conventionally, in order to exterminate such rats, various methods have been used, such as closing a hole through which the mouse enters and exiting, setting up a rat cage, arranging bait containing a rodenticide, and generating electromagnetic waves and sound waves hated by rats. The rats are exterminated or exterminated by the above method. In addition to rats, harmful small animals such as cockroaches and weasels are highly susceptible. If they sense an unusual odor in the active area, they will be alert and repelled, and will not appear in that area. The present invention focuses on its properties, and uses ozone gas to control harmful small animals. In addition, ozone gas also has a bactericidal action, and prevents the propagation of various germs and the generation of putrefactive odor accompanying the emergence of harmful small animals. Therefore, the use of ozone gas is preferable from that point of view.

[0004]

However, the conventional methods as described above have drawbacks in that they are complicated and costly. In addition, the control effect and sustainability are not sufficient, and there is no satisfactory method for controlling harmful small animals.

For example, even if the hole through which the mouse enters and exits is closed, a hole is made again at or near the closed position, and even if a rat cage is set up, the effect of the mouse is perceived and the capturing effect is reduced. You. In addition, even if a bait with a rodenticide is set, other rats will not see the poisoned bait by seeing the distress of the ingested rat. Devices that generate ultrasonic waves or light waves that repel small animals have also been tried for extermination of small animals, but harmful small animals become accustomed to them and lose their control effect over time. In addition, the method of setting up a bait containing a rodenticide or an insecticide is not safe because there is a concern that infants and other animals, such as domestic dogs and cats, may eat. Furthermore, disposal of captured and dead small animals is not easy.

Accordingly, an object of the present invention is to provide a method for exterminating small animals having the following features in order to solve the above problems. I. Easy removal of harmful small animals and no harm to the environment. B. The extermination effect is large and the effect is permanent. C. There is no risk of polluting the environment. D. Do not harm human animals.

[0007]

According to the method for controlling small animals of the present invention, ozone gas generated from an ozone generator is supplied to a space where small animals appear and disappear, and the concentration of ozone gas is reduced to 0.1 p.
It is characterized by controlling small animals by maintaining it in the range of pm to 10 ppm.

In the method for controlling small animals according to the present invention, the ozone gas is supplied to the space where the small animals appear and disappears, and the concentration of the ozone gas is maintained in the range of 5 ppm to 10 ppm, so that the small animals can recognize and memorize the ozone gas. After that, small animals are controlled by supplying ozone gas at a concentration lower than the concentration of the ozone gas.

Further, in the method for controlling small animals according to the present invention, the supply of the ozone gas and the lighting of the ultraviolet lamp are synchronized by using an ultraviolet lamp, and the supply of the ozone gas and the lighting of the ultraviolet lamp are associated with each other to recognize the small animal. -After storing the information, the small animals are effectively exterminated by turning on the ultraviolet lamp.

[0010]

DETAILED DESCRIPTION OF THE INVENTION In the method of the present invention, an ozone generator is used to open an empty attic, a kitchen,
Ozone gas is supplied to a place where small animals appear, such as a culvert, to maintain a predetermined concentration. By repeating this operation for several days, the small animal escapes the ozone gas, and escapes from the place and does not appear.

[0011] Specifications of the ozone generator used in the process of the present invention, when depending on and out of the volume or air in the processing space (the degree of sealing), to carry out disinfection of the rats in the space, for example 100 m ³ Is usually as follows: Ozone discharge concentration: 1 to 20 ppm Ozone generation capacity: 150 to 1000 mg / hr Ozone concentration in a steady state: 0.1 to 10 ppm Ozone generators of various specifications are already commercially available. Further, the amount of ozone gas used varies depending on the size of the processing space and the amount of air flowing in and out.

EXAMPLES <Experimental Example 1> Exterminating Rats with Ozone Gas Ozone gas oxidizes and decomposes various substances with a strong oxidizing power, and when its concentration is high, it acts as a poisonous gas even for humans and animals. Prior to the experiment described below, several rats were left in a closed cell, and ozone gas was supplied therein. After aeration at a concentration of 50 ppm for about 60 minutes, the majority of rats died over time. (It was presumed that bronchial disorder was caused and dyspnea occurred.)

An experiment was conducted using an apparatus as shown in FIG. The size of rooms A, B, and C is 50, respectively.
0 mm, depth: 600 mm, height: 200 mm. Room A
An ozone gas supply port 4 was provided, an ozone generator 5 was connected, and an ultraviolet lamp 6 was installed indoors. In addition, the bait 7 was placed in the center of the room A in advance. Passage 1 and room A,
Between B, the doors 2a and 2b through which rats can pass were provided. The door was made of an ozone decomposition catalyst plate to prevent ozone leakage to other places. A normal door 3 that can be opened and closed by an experimenter was provided between the room C and the passage 1.

First, one mouse is placed in room C,
The food was placed in room A, and the behavior of the mouse was observed without placing anything in room B. a. At first, the ozone was not supplied to the room A where the bait 7 was. Therefore, when the mouse recognized that the room A had the bait, the mouse went to the room A and started eating the bait. b. When the supply of ozone gas was started, the rats first responded to the smell of ozone, stopped taking food 7, and began to move actively in the room. c. When the concentration of ozone gas is increased to 3 ppm, passage 1
Tried to return to room C where he was originally, but moved to room B because door 3 of the passage was closed. d. After moving into room B, the rat tried to go to room A with food, but immediately returned to room B.

E. The supply of ozone gas to the room A was stopped, and after about 90 minutes had elapsed, it was confirmed that the ozone concentration in the room A had become 0 (zero), and the mouse was returned to the room C.
The behavior of the mouse was observed by replacing the feed 7 with a new one. f. A few minutes later, the rat went to room A and began to eat but seemed restless. g. When the ozone gas was supplied again at a low concentration, the rats stopped feeding and immediately moved from the aisle to room B. h. When the operation of the above item g was performed again, the mouse moved to the room B without eating the food. Thereafter, as a result of repeating this several times, the mouse once went to room A, but returned to room B without emitting ozone gas. Based on the above, rats have recognized the dangers of ozone,
It seems that they have begun to avoid.

I. This experiment was performed on the same rat in the pattern of the next day and three days later.
She went to room A, but came to room B after eating without eating.

Next, a mouse (red) and a new mouse (white), which were subjected to the same experiment for three days, were simultaneously placed in the room C to observe the behavior. j. The mouse (red) tries to go to room A where the bait 7 is located, but wanders in front of the passage and room B, and the mouse (white) enters room A while watching the mouse (red), but cannot rest, I was at a loss to eat food. (Here, the behavior of the mouse (red) approaching the mouse (white) frequently is presumed to convey the danger of the room A.) k. When a thin ozone gas was flown into the room A, the mouse (white) was at the door of the ozone decomposition catalyst plate, the door was opened halfway, and the ozone gas flowed through the passage. At the same time, a mouse (red) first enters room B, followed immediately by a mouse (white).
And two rats were moving around in room B in a restless manner.

L. Next, the supply of the ozone gas to the room A was stopped, and after confirming that the ozone concentration was 0 (zero), two identical rats were re-entered into the room C, and their behavior was observed. m. After two mice have left room C, the mouse (white) has room A
However, he was cautious as he was alert, and when the mouse (red) approached the mouse (white) two or three times, he moved to room B together. n. While two rats were in room B, ozone gas was supplied to room A, room A and the door 2a of the passage were opened, and the state of the rats was observed. o. When the mouse (white) tried to open the door 2b of the room B, he moved to the back of the room B as if he felt an ozone smell. The two rats moved around frequently, but did not try to approach door 2b.

<Experimental Example 2> a. A new mouse was put into the room A from the passage 1 and the door 2a of the experimental apparatus, and the door 2a was closed and fixed. At this time, no food was placed in room A, ozone gas was supplied, and the behavior of the mouse was observed. b. About 3 ppm of ozone gas was supplied to the room A for about 10 minutes, and the elapse of time and changes in the state of the mouse were observed. c. When the mouse started to supply the ozone gas, it moved around in the room A, approached the ozone supply port 4, but seemed to be away immediately and looking for an exit. d. After 15 minutes had passed, the movement of the rat became much slower and crouched in the corner near the door 2a of the room A. e. After 30 minutes, he sometimes went to the opposite corner and crouched, but almost stopped moving. At this point, the supply of ozone gas was stopped, the rats were moved to another room, and the experiment was terminated on this day.

On the next day, the rats were observed to confirm that they had regained energy, and then an experiment was performed. f. The experimental conditions were the same as in Experimental Example 1, with room 7 containing bait 7
The experiment was started after placing the mouse in the room C. g.
After leaving the room C, the mouse went to the room A and ate. 2
After about 3 minutes, when a very small amount of ozone gas was supplied to the room A, the door 2a at the exit was opened instantly, and the person went out into the passage, and went near the room B in a restless manner. Took about 2 minutes. In room B, as in the previous day, it crouched near the corner and did not move much.
(The fact that they did not enter Room B immediately seems to be cautious because the doors in both rooms had exactly the same appearance.) Also, perhaps because they remembered being exposed to the ozone gas atmosphere the day before, Instantaneously responded to the supply of ozone gas.

Three hours later, the rats were started from room C in the same manner, and the appearance was observed. h. The mouse took a considerable amount of time to enter room A, and occasionally went to room B. After 20 minutes, it entered room A, and while watching food 7, repeated the gesture of constantly smelling the ozone gas supply port. i. After flowing ozone gas of 0.5 ppm for about 10 minutes, the rat runs around the room like a rampage, exits the passage from the exit door 2a, enters the room B, moves around in a restless manner even in the room B, and after about 5 minutes Stopped crouching at the corner. As can be understood from the above results, the behavior of avoiding the danger of the mouse appeared earlier in Experimental Example 2 in which the danger of ozone gas was sufficiently recognized than in Experimental Example 1.

Next, an experiment on rat extermination using ozone gas and short-wavelength ultraviolet rays was conducted. Ultraviolet light is also harmful to humans at certain wavelengths, and exposure to ultraviolet light for a long period of time can cause irritation to eyes and skin. It seems that rats also instinctively sense that.

<Experimental Example 3> In the same manner as in Experimental Examples 1 and 2, a mouse is started from the room C, and an ultraviolet lamp 6 is used in addition to the ozone generator 5 to see how the mouse reacts. Was observed. The supply of ozone and the irradiation of ultraviolet light started simultaneously. In this experimental example, a test is performed to determine how the ultraviolet light affects the mouse and whether the mouse recognizes that the supply of ozone is started when the ultraviolet lamp is turned on.

A. First, the mouse recognized that there was food 7 and entered room A, and began eating food. b. After a lapse of a few minutes, the ozone supply and ultraviolet irradiation were started at the same time, and because of the surprise of the ultraviolet light, they moved around in the room A violently and approached the ozone supply port from the ultraviolet lamp 6 several times. Exit from room A and exit to room B
went inside. c. Immediately, the supply of the ozone gas and the irradiation of the ultraviolet ray in the room A were stopped, and it was confirmed that the ozone concentration had become 0 (zero). After a further two hours had elapsed, the rats were placed in the room C and observed. d. Tens of minutes later, the rat entered Room A and wandered around the freshly re-stocked bait 7, or moved around the UV lamp and ozone supply. e. Seven to eight minutes after entering room A, it was confirmed that the rats began to eat food, and the supply of ozone gas and the irradiation of ultraviolet rays were started. f. The mouse stops feeding, and then goes to the exit and moves its nose to smell the ozone.
And entered room B.

The above experiment was performed three times over two days, and the same experiment was performed five days later on the same rat. In this experiment, we turned on the UV lamp first and observed how the mouse behaved. g. The mouse that came out of room C was hesitant to enter in front of room A, but after about 30 minutes, finally entered room A,
Without eating food, he moved back and forth around the UV lamp and the ozone supply. h. Although only the ultraviolet lamp 6 was turned on, the mouse near the ozone supply port immediately came out of the door 2a of the room A, and came out of the room B.
Moved to i. The same experiment was repeated four times, but the fourth time, the mouse that was far from the UV lamp, noticed the UV lamp, but did not immediately leave room A. Seconds later, he left Room A and wandered down the aisle. After that, he sometimes tried to enter room A, but finally entered room B. j. Several days later, the supply of ozone and the turning on of the ultraviolet lamp were repeated several times, and as a result, the mouse repeated the operation of leaving the room A at the same time as the turning on of the ultraviolet lamp.

The next day, an ultraviolet lamp (not shown) is placed in room B.
Only, and observed the state of the rat. k. The mouse that left Room C did not try to go to Room A.
A few minutes later, when I went to room B, I turned on the ultraviolet lamp in room B. The rat checked the ultraviolet lamp through the door and did not enter room B, but went in the direction of room A, but also in room A He was walking back and forth without entering. l. The mouse made a gesture of opening door 3 to return to room C, but was hovering around the passage because the door did not open.

<Experimental Example 4> A new mouse was placed in the room B, the door was closed, the ultraviolet lamp was continuously turned on, and the behavior of the mouse was observed. a. After turning on the ultraviolet lamp, he or she was running around in room B for 4 to 5 minutes or approaching the lamp.
After that, as with the supply of ozone gas, the user crouched back toward the ultraviolet lamp and did not move much. In the case of only an ultraviolet lamp, there was a case that it did not come out of the room.
Therefore, it was found that the mouse could not be driven out only by ultraviolet irradiation.

[0028]

From the above experimental examples, the following effects can be expected according to the method of the present invention. 1. Since small animals such as rats avoid ozone gas and take evasive actions, it is possible to exterminate small animals by supplying ozone gas. 2. When the ozone gas and the ultraviolet lamp are used together, the supply of the ozone gas and the turning on of the ultraviolet lamp are simultaneously repeated several times, so that the ultraviolet lamp can be recognized as a signal of the ozone gas supply, and thereafter, the turning on of the ultraviolet lamp is performed. Only small animals can be exterminated. 3. When one of the small animals recognizes that only the supply of ozone gas or the simultaneous supply of ozone gas and the turning on of the ultraviolet lamp will be notified to other friends, the entire small animal will be placed in the space where these devices are installed. I will not approach. However, in the case of an ultraviolet lamp alone, the approach to the lamp is avoided, but if there is a distance from the lamp, the lamp may become accustomed and the effect of exterminating small animals may not be expected.
