Description

The present invention relates to a method for repelling rats using smoke and a repellent .

  Conventionally, the damage caused by rats scolding food, wall materials, electric cables and the like has been a problem, and various rodenticides and repellents have been studied to prevent such damage. However, the desired effect can be obtained only at the place where the rodenticide or repellent is treated, and it is difficult to expel the mouse from a wide space such as a room, a warehouse, or under the floor.

Conventionally, it has been studied to avoid animal pests with smoke. For example, ignite a molded product made of wood powder, starch, etc., smoke it to avoid birds (see Patent Document 1), smoke the pest habitat, expel the pest, and use the adhesive material installed Capture and extermination (see Patent Document 2) and the like are known.
However, birds, pests, and rats differ in habits, behaviors, responses to stimuli, etc., and the above document does not describe application to mice.
And about the mouse | mouth, the repelling method using smoke is not examined, but what impregnates the member with the smell of smoke components, such as tar (refer patent document 3) is a grade known. .

Therefore, in the present invention, after all, to exhibit a strong repellent effect on rats without using a repellent, and provides a repelling methods and repelling agent murine using smoke.

As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention have , as an active ingredient, smoke generated by thermal decomposition of azodicarbonamide , which does not contain a repellent, and the smoke has a height from the floor surface. but in 10 to 30 cm, the average amount of dust per minute was measured with a digital dust meter reaches the heading invention repellency method murine, characterized in that to generate such a more smoke volume 45 cpm.
Furthermore, the present invention contains azodicarbonamide, does not contain a repellent, and generates smoke as an active ingredient that repels rats when thermally decomposed by heating, and the smoke generates a smoke amount of 45 cpm or more. It is intended to provide a mouse repellent characterized by the above.

According to the present invention, to exert a strong repellent effect against murine when azodicarbonamide without using the memorial避剤is only smoke produced by thermal decomposition and having a smoke of more than 45cpm it can.

  The method for avoiding a rat according to the present invention uses smoke generated by thermal decomposition of azodicarbonamide as an active ingredient, and diffuses the smoke so as to have a smoke amount of 45 cpm or more, preferably 100 cpm or more, more preferably 200 cpm or more. Thus, mice can be repelled without using a so-called repellent. In particular, it is preferable to directly expose the smoke amount to mice. This can surely avoid (purge) the rat.

  As the azodicarbonamide, those that thermally decompose at around 200 ° C. to generate smoke are preferable, and examples thereof include Uniform AZ (manufactured by Otsuka Chemical Co., Ltd.), Cellmic CE (Sankyo Kasei) and the like.

The smoke amount in the present invention means an average dust amount (cpm) measured for 1 minute with a digital dust meter when the height from the floor surface is about 10 to 30 cm indoors, in a warehouse, under the floor, etc. Can be measured by, for example, a digital dust indicator model P-3 (manufactured by Shibata Chemical Co., Ltd.).
In the present invention, for example, measurement is performed a plurality of times at arbitrary intervals for 30 minutes from the generation of smoke, and the average value is defined as the amount of smoke.
In repelling methods and repelling agent of murine present invention, azodicarbonamide to generate a predetermined smoke amount smoke generated by thermal decomposition, 0.2 g or more with respect to 20 to 50 m ^3, preferably 1 to 30 g may be used.

  In addition, in an apparatus using a double container as shown in FIG. 1 below, smoke is slightly generated just by heating the container. Therefore, the amount of smoke generated by thermally decomposing azodicarbonamide is azo The amount of smoke is measured when dicarbonamide is present in the container and when it is not present, and the difference is defined as the amount of smoke generated by thermally decomposing azodicarbonamide.

  In the murine repellent method of the present invention, the thermal decomposition of azodicarbonamide is carried out by, for example, storing azodicarbonamide in the container of the smoke generator shown in FIG. 1 and heating it by heating means arranged outside the container. It can be carried out.

  Examples of the container include a plastic container, a paper container, a metal container, a ceramic container, and a glass container. In addition, as a heating means, for example, a hydrothermal exothermic method using a reaction between a hydrothermal exothermic substance such as calcium oxide, magnesium oxide, magnesium chloride, aluminum chloride, calcium chloride, iron chloride and water (see FIG. 1), iron carbide, Air oxidation heat generation method using metals that generate heat due to oxidation reaction such as a mixture of iron powder and ammonium chlorate, a mixture of iron and potassium sulfate, electric heating method using heaters such as nichrome wire, positive temperature coefficient thermistor, semiconductor heater, A platinum catalyst system etc. are mentioned.

The illustrated smoke generating apparatus 1 includes a cylindrical outer container 2 with a bottom, and a hydrothermal exothermic substance A is accommodated from the bottom to the side. Further, the inside of the outer container 2 is partitioned into two spaces by a partition member 4. The outer container 2 has a plurality of water holes at the bottom, and the water holes are closed by a member having water permeability, for example, a nonwoven fabric sheet 3. In use, the smoke generator 1 is placed in a container 20 containing water W, so that the water W flows into the outer container 2 through the water passage hole, and further penetrates the nonwoven fabric sheet 3 to come into contact with the hydrothermal substance A. The azodicarbonamide B is heated and decomposed by the generated reaction heat, and the generated smoke is released to the outside (inside the room) through the vent of the hot melt film 7 and the opening of the lid member 6.

  Such a device can be placed in a place where a mouse lives or is active, or in a narrow place such as an attic or under the floor, smoke generated in another place can be supplied by a pipe or the like.

The mouse repellent method and repellent of the present invention is a smoke that is generated by thermal decomposition of azodicarbonamide without using a repellent, and exhibits a repellent effect of the mouse sufficiently by the predetermined amount of smoke. It is . Moreover, a fragrance | flavor, a deodorizing agent, etc. can also be used together with respect to a mouse | mouth as needed .

EXAMPLES The present invention will be described in more detail with reference to examples below, but the present invention is not limited to these examples.
[Test Example 1]
Using the test apparatus shown in FIG. 2, the repellent effect of mice by the repellent method of the present invention was confirmed as follows.
A bat (length 1 m, width 1.5 m, height 1 m) was installed in Room A (length 3 m, width 4.5 m, height 2.5 m). Next, a cage (length 40 cm, width 25 cm, height 20 cm) was installed in room B (length 3 m, width 4.5 m, height 2.5 m). The bat and cage were connected by a pipe (diameter 7.5 cm, length 50 cm) penetrating the wall so that the mouse could move freely.
Furthermore, the room A was darkened and the cage of the room B was irradiated with 300 W illumination (mice don't like light, so the condition was that they would normally not enter the room B). Then, 5 mice (mouse) were released in the A room and the B room side was observed.
Smoke was generated from the test specimens listed in Table 1 installed on the floor of Room A, and the number of mice that entered Room B over 30 minutes was counted as the number of mice evaded, and the residence time at that time Was observed. The mice that entered the B room and returned to the A room were counted in the same manner when they moved to the B room again.
The test specimens, Examples 1 to 3, housed in a partition member of the smoke apparatus azodicarbonamide amounts described (dose) Table 1, the outer container so as to be located outside the partition member Storing 65 g of calcium oxide, adding water to generate heat at about 300 ° C. and heating, pyrolyzing azodicarbonamide to generate smoke.
In Comparative Example 1, nitrocellulose, which is a commercially available smoke agent in the amount (dose amount) shown in Table 1, was stored in a container and ignited to generate smoke.
As a control, azodicarbonamide was not housed in the partition member of the example, and heated in the same manner as in Example 1 with calcium oxide in an empty state.

The test results are shown in Table 1.
In Examples 1 to 3 using azodicarbonamide, the total value of the repelled mice increases as the dosage increases. Further, even when the amount used was 0.2 g, a clear difference was recognized as compared with the control. When the nitrocellulose which is a comparative example was used, there was no big difference compared with control.

[Test Example 2]
For Examples 1 and 2, Comparative Example 1, and Control used in Test Example 1, the amount of smoke was measured with a digital dust indicator model P-3 (manufactured by Shibata Chemical Co., Ltd.).
The smoke amount was measured by placing each specimen on the floor surface of the room A of Test Example 1 to generate smoke, measuring the smoke amount at intervals of 5 minutes for 30 minutes from the generation of smoke, and obtaining the average value.
As a result of the measurement, even if it was a control, the container was heated, and the average amount of dust was about 309 cpm. Therefore, the average dust amounts of Examples 1 and 2 and Comparative Example 1 were corrected by subtracting the control value, and the value is shown in Table 2.
The test results are shown in Table 2. When azodicarbonamide was used, the amount of smoke was almost proportional to the amount used. The amount of smoke when the nitrocellulose of the comparative example was used was about 7 times that when azodicarbonamide was used.
From this result, it is understood that the amount of smoke is not necessarily large, and smoke generated by thermal decomposition of azodicarbonamide is effective in avoiding rats with a small amount of smoke as compared with the comparative example.

[Test Example 3]
In addition to the sample of Example 3, mint oil 10% ( Reference Example 1 ), mint oil 10% and essential oils 2% ( Reference Example 2 ), mint oil 8% and essential oils 4% ( Reference Example 3 ) The test specimens were manufactured and tested in the same manner as in Test Example 1 to confirm the repellent effect of mice.
The essential oils are oils containing 40% rosemary oil, 10% terpineol, 10% terpinene, 10% P-cymene and 5% hexyl acetate.
Mentha oil is an oil containing 40% l-menthol and 20% menthyl acetate.
The test results are shown in Table 3. When mint oil was blended ( Reference Example 1 ) and when mint oil was blended with 2% essential oils ( Reference Example 2 ), there was no difference in repellent effect. When the amount of essential oil added was increased ( Reference Example 3 ), a clear improvement in repellent effect was observed.

It is sectional drawing which shows one form of the apparatus which thermally decomposes azodicarbonamide and generate | occur | produces smoke. It is the schematic of the apparatus used for the test example of this invention.
