Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to repellents for animals such as rats, stray cats, stray dogs, crows, pigeons, ants, cockroaches, weevils, mites, house dust mites, fleas, termites and aphids.

[0002]

2. Description of the Related Art Conventionally, rats, stray cats, stray dogs,
Crows, pigeons, ants, cockroaches, weevil, mites,
There is a need to repel non-preferred animals from house dust mites, fleas, termites, aphids and other sanitary, horticultural cultivation and pollution.

[0003]

In particular, it has been seen in various places that animals kept as pets during the bubble growth period are discarded and walk around for food. These have emerged not only in fields and warehouses, but also in gardens and verandas, and prevention of their intrusion is required.

[0004] In addition, crows litter and litter at garbage collection points, and pigeons act collectively to cause fecal pollution. Ants and cockroaches are also unwelcome animals. Small insects such as aphids and termites attached to weevil and plants are also great enemies for rice, plants and houses. As these repellents, repellents containing, for example, M-bentonite, zeolite and the like as active ingredients are commercially available, but these have slightly different odor qualities, but for example, the strong rotten odor of fish and vegetables or the intense odor of lemon. It emits an unpleasant odor or the like, and it is difficult for humans to endure it, and its durability is short, and most of them have an effective period of at most several weeks.

An insect repellent comprising naphthalene as an active ingredient,
There are insect repellents containing paradichlorobenzene as an active ingredient, and insect repellents containing camphor as an active ingredient, all of which use the active ingredient naphthalene or the like in combination with a large amount of a filler such as calcium carbonate or talc. Thus, the amount of the active ingredient was small, and the degree and duration of the repellent effect were insufficient. An object of the present invention is to provide an animal repellent which is extremely excellent in repellent effect, has immediate effect and long-term persistence, and can effectively prevent invasion of pests and animals.

[0006]

SUMMARY OF THE INVENTION The present invention provides an animal repellent comprising a residue obtained by adding naphthalene to a solvent containing a denatured alcohol comprising an ethanol / isopropyl alcohol mixture in an amount of at least a saturated solubility and stirring, and then removing the supernatant solution. Pertaining to the agent. The present invention also relates to an animal repellent obtained by adding a solvent containing a denatured alcohol composed of an ethanol / isopropyl alcohol mixture to naphthalene.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a mixture of ethanol / isopropyl alcohol is used as a denatured alcohol. The ratio of ethanol / isopropyl alcohol can be selected from a wide range, but usually, the weight ratio of ethanol / isopropyl alcohol is 50 to 99/1 to 50,
Preferably it is about 70 to 95/5 to 30. As the solvent, one obtained by blending at least one selected from methanol, butanol, acetone, methyl ethyl ketone, benzene, toluene, gasoline, kerosene, olive oil, and terpene oil with the denatured alcohol comprising the above-mentioned ethanol / isopropyl alcohol mixture is used. You can also. The amount of these components is about 0.1 to 50 parts by weight, preferably about 1 to 20 parts by weight, based on 100 parts by weight of the denatured alcohol.

[0008] The animal repellent of the present invention can be obtained by adding naphthalene to a solvent containing the above-mentioned denatured alcohol in an amount of at least a saturated dissolution amount, stirring, and then removing the supernatant solution.
Further, this residue may be dried. Alternatively, the animal repellent of the present invention can be obtained by adding a solvent containing a denatured alcohol composed of an ethanol / isopropyl alcohol mixture to naphthalene, and drying if necessary.

According to the method of the present invention, a high-concentration naphthalene impregnated with a solvent can be easily obtained. In this case, if the solvent evaporates during use, 100% of naphthalene is produced.
Alternatively, the solvent may be removed in advance by drying. In the present invention, natural camphor or synthetic camphor may be used as a part of naphthalene. It is preferable that a fragrance is further added to the animal repellent of the present invention because the odor is alleviated. The fragrance may be added at the time of production or after production. Any fragrance can be used, for example, jasmine, lemon, lavender, mokusei, etc., and the amount of addition can be determined as appropriate, but usually about 0.0001 to 0.001 to the product.
The content is preferably about 2% by weight, but is not limited thereto.

The animal repellent of the present invention may have any shape and form, for example, a form stored in a tube, a plastic bag, a glass container, or the like. In addition, a paste can be added to the repellent of the present invention. By adding glue, the film spreads on the place where it was sprayed, applied or placed,
The effect lasts longer. Any paste such as a synthetic paste or a natural paste can be used as the paste, and particularly preferred are CMC (carboxymethylcellulose), PVA (polyvinyl alcohol), and vinyl resin. The amount of the paste added is appropriately determined, but is usually about 0.5 to 20% by weight, preferably about 1 to 5% by weight, based on the repellent.

The repellent of the present invention can contain a high concentration of naphthalene. Conventionally, as described above, there have been insect repellents using naphthalene in a solid state, but in that case, the amount of naphthalene was small. On the other hand, since the repellent of the present invention can contain a high concentration of naphthalene, the repellent effect is extremely excellent, and has an immediate effect and a long-lasting effect. In addition, when the solvent evaporates when a paste is used, 10
0% of naphthalene is wrapped in a glue film, and its durability is extremely excellent.

The repellent of the present invention is effective in various fields, for example, rats, stray cats, stray dogs, crows, pigeons, ants, cockroaches, weevil, mites, house dust mites,
It has a repellent effect on fleas, termites, aphids, and other animals, including weevil, mites, house dust mites, fleas,
It has an insecticidal effect on small animals such as termites and aphids. The repellent of the present invention is, for example, a living room, a corner of a kitchen, a clothesline, a handrail such as a veranda, an underside of a ceiling, a gap portion such as a drain pipe, a narrow passage which becomes a passage of a rat, an under the ceiling, a gap portion such as a drain pipe and the like. It is preferably applied, but not limited to.

[0013] It can also be used for the passage of small animals. In this case, small animals such as aphids that attach to plants may be repelled and die at the same time. Even small rice weevil can be repelled and die at the same time in rice. The repellent of the present invention does not have a bad smell, is extremely excellent in repellent effect, and has immediate effect and long-lasting effect, and the effect lasts for several months, for example.
