Description

The present invention relates to a small animal repellent material and a small animal repellent method that are installed in a predetermined place to control crows, pigeons, and mice (hereinafter referred to as small animals) , and particularly to a technique suitable for controlling crows.

  Conventionally, damage caused by small animals such as devastation of garbage collection sites by pigeon droppings and crows has occurred, and various methods have been used to prevent such damage. For example, as a method of preventing crow damage at a garbage collection site, a method of enclosing the entire garbage collection site with a net, or a method of spraying repellents of components that the crow avoids directly onto a garbage bag can be exemplified.

  In the method using the net, the entire garbage collection site where crows are damaged is surrounded by a net without any gaps, thereby preventing the entry of the crow into the garbage collection site. Therefore, if there is a gap between the nets, the crow enters through the gap, so the entire garbage collection site must be surrounded by the net without any gaps. For example, every time the net is opened or closed, such as when throwing away trash, the net must be arranged without any gaps, which is troublesome. In addition, when the net is damaged, there is a possibility that the crow may enter from the damaged portion, so that it is necessary to frequently maintain the net.

  Moreover, the method using the spray is, for example, a method of spraying mint containing menthol as a main component and controlling crows by the pungent odor of the mint. According to this method, it is only necessary to blow a solvent having an irritating odor to a place where crows are to be controlled, and maintenance work can be saved compared to a method using a net. However, once the repellent material is sprayed, the effect cannot be obtained if the irritating odor is eliminated, and therefore a long-term effect cannot be expected. On the other hand, while the effect lasted, people often felt discomfort due to the pungent odor.

The present invention has been made in view of such problems, and can be used for a long period of time without being restricted by the place of use, has little influence on the body, and can be used safely . It is a technical problem to provide a repellent material and a repellent method for pigeons and mice .

The present invention employs the following means in order to achieve the above object. That is, the present invention is a small animal repellent material, in which a base material impregnated with naphthenic acid is covered with a water-resistant cover, and a spacer for forming a predetermined space is disposed between the cover and the base material. And an air flow passage is formed between the substrate and the cover . In the test described later, it was confirmed that small animals can be repelled by this naphthenic acid . In here, a naphthenic acid, cyclopentane derived from petroleum, cyclohexane is a generic name for carboxylic acid derivatives of descriptors such as cyclohexane, generally used in paint drying agent, wood preservatives, metal fabrication such as It has been. The acute toxicity of naphthenic acid is LD50 = 3000 mg / kg (oral administration in rats), which is a low toxicity and highly safe substance.

  The base material is not particularly limited as long as it can absorb naphthenic acid, and its material, shape, size, thickness and the like are not limited. Examples of the substrate include cloth and sponge. In particular, a cloth can be preferably used from the viewpoint of ease of handling and the like, and a naphthenic acid can be held for a long time by using a cloth having high water absorption.

The present invention also relates to a method for avoiding crows, pigeons and mice, wherein naphthenic acid is diluted with an organic solvent, a base material impregnated with the diluted solution of naphthenic acid is brought into contact with the outside air, and naphthenic acid is introduced into the outside air. It may be characterized by dissipating acid. An organic solvent in which naphthenic acid is dissolved is absorbed by the base material, and the base material is placed in a place having good air permeability. According to this method, the naphthenic acid can be vaporized and the small animals can be controlled by bringing the substrate into contact with the outside air.

  Naphthenic acid is usually in the form of a gel, and it is considered that it is difficult to absorb the naphthenic acid only by naphthenic acid. Naphthenic acid is insoluble in water, but is soluble in organic solvents. Therefore, naphthenic acid is dissolved in an organic solvent to improve fluidity and make it easier for the substrate to absorb it.

  The organic solvent is a liquid organic compound, and examples thereof include benzine and xylol. However, the organic solvent is not limited to these as long as it can dissolve naphthenic acid.

Furthermore, the method for avoiding crows, pigeons, and mice according to the present invention may be characterized in that a base material that has absorbed an organic solvent in which naphthenic acid is dissolved is suspended from above, and the base material is rotatably installed. By suspending the base material from above, it is possible to make a large amount of contact with the surrounding air. Furthermore, by rotating the base material, it is possible to efficiently vaporize naphthenic acid.

  In the present invention, the base material impregnated with the naphthenic acid is covered with a water-resistant cover, and a spacer for forming a predetermined space is provided between the cover and the base material. It is desirable to form an air flow passage between the cover and the cover. According to the present invention, the small animals to be controlled are also small outdoor animals such as crows. Therefore, a base material impregnated with an organic solvent in which naphthenic acid is dissolved is often installed outdoors. However, if the base material is placed outdoors so as to be in contact with the outside air, naphthenic acid absorbed by the base material may flow out due to the weather, for example, when it rains. In such a case, the naphthenic acid can be prevented from flowing out due to rain or the like by covering the substrate with a water-resistant cover. Furthermore, for example, if the base material is covered with a cover while being in close contact with the base material, the air permeability of the base material is deteriorated, and naphthenic acid is hardly vaporized. Therefore, it is desirable to form an air flow path between the substrate and the cover. In the present invention, a spacer is disposed between the cover and the substrate. By this spacer, a space is formed between the cover and the base material, the air permeability of the base material is improved, and small animals can be controlled by efficiently vaporizing naphthenic acid.

The crow, pigeon, and mouse repellent material according to the present invention may be characterized in that the base material is fixed to a plate material having a predetermined hardness. Since the base material is fixed to the plate material, the base material has a certain form, so that it can be used, for example, for portable use.

As described above, according to the present invention, it is possible to control a small animal safely and easily without being restricted in place. Moreover, the repellent effect of the crow, pigeon and mouse repellents according to the present invention lasts for at least about one month, and can be used for a long time without the need for maintenance.

Examples of the present invention will be described below.
(Manufacturing method for small animal repellent)
First, 3 L of kerosene is prepared as an organic solvent for dissolving 3 L of naphthenic acid and this naphthenic acid. Then, the naphthenic acid and the organic solvent are stirred to dissolve the naphthenic acid in the organic solvent. Next, a belt-like cloth 1 is prepared, and the cloth 1 is dipped in an organic solvent in which naphthenic acid is dissolved, and left as it is for 3 days to be sufficiently absorbed by the cloth 1.

  After the elapse of 3 days, the cloth 1 is taken out and hung with a string 4 from above and covered with a vinyl cover 2. A wooden piece 3 as a spacer is previously provided inside the cover 2. By providing this piece of wood 3, an air flow passage 10 is formed between the cloth 1 and the cover 2, and the organic solvent is easily vaporized. Furthermore, the swivel joint 5 which can rotate freely is connected to the string 4 which suspends this small animal repellent material, It becomes possible to rotate with the force from the outside, such as a wind, and to efficiently vaporize naphthenic acid. (See FIGS. 1 and 2).

(How to use small animal repellent)
The cloth 1 covered with the cover 2 is installed in a place where a small animal is desired to be controlled. For example, when controlling a small animal entering the room from the outside, it is installed at the upper part of the door as the entrance or the upper part of the window. A relatively high place is suitable for the place of installation because repellents are distributed around. In particular, this is effective in the case of a building having a doorway, window, etc. that must be opened or opened frequently. In addition, for example, when controlling indoor small animals, it may be installed in a kitchen in which rats or the like are relatively easy to gather, and the inside of the cupboard is effective. In addition, in order to suppress or prevent damage to birds such as manure damage, crop damage, and obstruction of aircraft operation, it is effective to install near or outside facilities or buildings that need to be avoided.

  Furthermore, when installing in a relatively high place, it is better to hang it with a string etc. from above, for example, in an airport where birds are frequently damaged, prepare multiple cloths and arrange them around the airport It is effective when hung. In addition, when installed indoors or carried around for portable use, it is convenient to carry and install by fixing to a plate having a predetermined hardness.
