Abstract

PURPOSE:To control flea, mite, mosquito, etc., parasitic on pet by using a carrier supporting a substance volatile at normal temperature and free from pet repellen cy and applying the substance to a pet-container such as kennel, thereby converting the atmosphere in the container to the atmosphere of the above volatile substance. CONSTITUTION:A substance volatile at normal temperature and free from pet repellency (e.g. 1-ethynyl-2-methyl-2-pentenyl cis/transchrysanthemate) is used as a vermin-controlling agent component and is supported on a carrier. The carrier is applied to a pet-container such as a kennel to fill the container with the volatile component atmosphere and control the vermin such as flea, mite and mosquito parasitic on the pet. The carrier is wood (e.g. Japanese yew, fir and white fir), a paper material (e.g. corrugated cardboard), a synthetic resin material (e.g. polyester), etc., and an animal house is constructed of the material impregnated with 5-200g/m<2> of the agent.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for controlling pests, and more particularly, to a new method for effectively controlling pests parasitic on pets.

Conventional technology Conventionally, as a method of controlling pests such as fleas that parasitize pets such as dogs, there have been methods of applying pest control agents such as flea powder directly to the animal body by spraying or spraying as appropriate. A method is known in which a so-called pet collar, in which a pest control agent component is kneaded into a collar, is applied to an animal body.

However, the method of applying pest control agents is itself complicated and has the disadvantage that it is temporary and has no lasting effect. On the other hand, pet collars control pests by utilizing the fact that when applied to an animal's body, the pest control ingredients in the collar gradually transfer to the animal's body hair and come into contact with the pests parasitic on the body hair. Although it has a certain degree of sustained effect, it has the drawback that the transfer of the above-mentioned pest control agent to body hair is uneven, and the contact between the pest control agent and insect pests is still low, and a sufficient pest control effect cannot be achieved.

As mentioned above, all conventional pet pest control methods merely control pests through contact with a pest control agent, and have various disadvantages.

Problems to be Solved by the Invention In view of the above-mentioned current situation, the inventors of the present invention have developed a pest control agent that is volatile at room temperature, instead of the conventional method of controlling pests by contact, which has various disadvantages. We have been conducting extensive research with the aim of providing a new method for controlling pests for pets, which uses so-called paper action, which involves the volatilization of chemicals.

In the process, it was recognized that dichlorvos (DDVP), which is volatile at room temperature, exists among the ingredients used as insect repellent ingredients for conventional pet colors. Almost no pest control effect was observed by action, and only a pest control effect by contact was observed. In addition, if we use the above DDVP to control pests by paper action, it is necessary to use a fairly large amount of DDVP, and it is difficult to create pet collars using such a large amount of DDVP. It has been recognized that when such a large amount of DDVP is used, it becomes repellent to pets, and the pets themselves are reluctant to apply it, and if the application is forced, DDVP has an adverse effect on the pets themselves.

However, in subsequent research, the present inventors used a specific room-temperature continuous failure substance as a pest control agent component, and when creating a pet housing such as a large shed using a carrier holding this substance, the atmosphere inside the housing was The atmosphere created is sufficient for the paper action of the pest control agent volatilized from the carrier to be effective, and fleas, ticks, mosquitoes, etc. that parasitize the pets in the container are successfully controlled, which is truly surprising. Despite the atmosphere in which the above chemicals were highly concentrated, pets did not show any repellency and did not release them (from the contents).
Therefore, there is no need to forcibly confine the pet in a container, and there is no adverse effect on the pet itself, and the pest control described above can be carried out naturally, and this pest control effect can be sustained over a very long period of time. I discovered a fact.

The present invention has been completed based on the discovery of the above facts.

In order to solve the problem, the present invention uses a room-temperature volatile substance that does not substantially have repellency to pets as a pest control agent component, and uses a carrier holding the room-temperature volatile substance to accommodate pets. apply to things,
A pest control method characterized by controlling pests such as fleas, mites, and mosquitoes that parasitize pets by creating an atmosphere in the container as a volatile component atmosphere that evaporates from the carrier, and retaining the room temperature volatile substance. This invention pertains to insect-proof dog kennels and animal kennels made from carriers made of

As mentioned above, the pet pest control method of the present invention is a new method that uses paper action using a room temperature volatile pest control agent, and is not repellent to pets.
It has no adverse effect on pets and can maintain a sufficient pest control effect over a long period of time. In addition, the insect-proof dog house or animal house according to the present invention is particularly suitable for carrying out the method of the present invention described above, and can exhibit the same excellent pest control effect.

The room-temperature volatile substance used as a component of the pest control agent used in the present invention does not show repellency to pets such as dogs in the large hut of the present invention obtained using the same, and is sufficient to prevent pests by paper action. It is selected from drugs that can exert a pesticidal effect, specifically 1-
Ethynyl-2-methyl-2-pentenyl cis/trans-chrysanthemate Common names: empenthrin, eucalyptus oil, DEET, melissa, peppermint, 4-methylacetophenone, 3-allyl-2-methylcyclopenta-2 -en-4-one-1-yl 2
, 2,3.3-tetramethylcyclopropanecarboxylate (common name niterarethrin), 1-ethynyl-2-
, methyl-2-pentenyl 2,2,3.3-tetramethylcyclopropanecarboxylate and 1-ethynyl-2methyl-2-pentenyl 2,2-dimethyl-3-
(2,2-dichlorovinyl)cyclopropane-1-carboxylate may be mentioned.

Through the above-mentioned paper action, these drugs have an excellent control effect on fleas, ticks, etc. that live in the pet's body hair, as well as flying pests such as mosquitoes that carry the Phylanoa pathogen, and can cause the insects to fall off from the pet's body hair. , can be controlled. One type of the above-mentioned specific drugs can be used alone in the present invention, or two or more types can be used in combination. The amount to be used is not particularly limited, and the type and amount of the carrier used to continue to hold the drug according to the present invention, the size of the animal housing such as a large shed to be made with the carrier, etc. It is determined as appropriate depending on the type and size of the pet to which it is applied, the required pest control effect, etc.

Generally, the amount of impregnation is selected from up to saturation with respect to the carrier for holding the drug, and the amount of impregnation is approximately 0.1 to 500 g, preferably approximately It is appropriate to select from a range of about 5 to 200 g.

Further, in the present invention, the carrier used to retain the above-mentioned specific pest control room-temperature volatile substance may be any material as long as it is capable of retaining the above-mentioned agent. Wood, paper, synthetic resin materials, etc. that are commonly used are suitable. Typical examples of the above-mentioned carriers include yew, fir, Sakhalin fir, rainbow pine, Japanese red pine, Japanese black pine, Japanese pine, hemlock, cedar, Japanese walnut, Japanese walnut, Japanese staghorn, Japanese oak, Japanese oak, beech, Quercus oak, Chinese elm, Japanese zelkova, camphor tree, Japanese elm 1 , Hiba,
Compression made by compressing various types of wood such as cypress, Japanese cedar, Aodamo, Shioji, Kiri, Pencil fern, Myatou 1, Jongkon, Chirophyllum, Town, Zientol, Agatis, etc., plywood, plywood, and wood powder and hardening them with a binder. Examples of the material include paper materials such as cardboard boards and wood II boards, and synthetic resin materials such as polyester, polyethylene, polyvinyl chloride, polyurethane, polyacetal, polyvinylidene chloride, and polycarbonate. The various materials mentioned above may be in the form of, for example, hollow resin, hollow wood, hollow wood filled with resin, or the like.

In the present invention, the room-temperature volatile substance is retained on the carrier by first dissolving, emulsifying, and dispersing the drug directly or, if necessary, in an appropriate solvent, and then applying the resulting solution to the carrier. This can be carried out by means such as impregnation (under normal pressure, reduced pressure, or increased pressure), coating, or spraying.

Here, the solvent used for dissolving, emulsifying, and dispersing the above-mentioned drug is a usual one, such as hexane, 3,
3. Oil-based solvents such as 4-trimethylnonane, cyclohexane, kerosene (kerosene), naphtha, normal paraffin, isoparaffin, and liquid paraffin, chlorinated hydrocarbons such as dichloroethane and trichloroethane, ethyl alcohol, isopropyl alcohol, triethylene glycol, Examples include alcohols and ethers such as polyethylene glycol and ethylene glycol, and esters such as dimethyl phthalate, diethyl phthalate, diisopropyl phthalate, dibutyl phthalate, and diethylhexyl phthalate. Among these, ethylene glycol, triethylene glycol, propylene glycol, polyethylene glycol with a molecular weight of 200 to 600,
Liquid nonvolatile solvents such as normal paraffin, isoparaffin, and liquid paraffin are particularly preferred because they improve the durability of the pet house and are not repellent to pets.

In the present invention, from the viewpoint of improving the durability of the animal house and making it easier to clean, an appropriate water repellent or the like may be added to the above-mentioned room-temperature volatile substance. Examples of the water repellent include silicone compounds, fluorine compounds, aluminum stearate, magnesium stearate, and paraffin. Furthermore, substances that improve the comfort of animals in the animal house, such as trace amounts of trimethylamine, indole, scallop, hydrogen sulfide, ammonia, etc. alone or in mixtures, fish soluble, beef soluble, chicken soluble, Pork soluble, Actinidia, meat extract, fruit flavor, meat flavor [bis(2-methyl-3-furyl) disulfide, 3,5-diisobutyl-1,2,4-trithiolane, 2-isobutyl-3,5-diisopropylpyridine It is also possible to add and use at least one of fish meat flavor, peanut oil, etc.], fish meat flavor, peanut oil, etc. Furthermore, ordinary deodorants (e.g. lauryl methacrylate-1, geranyl crotonate, etc.), surfactants, antibacterial and antifungal agents (e.g. PCMX
, TBZ, etc.), fragrances, preservatives, rust preventives, etc., may be optionally added and blended in appropriate amounts.

Regarding the retention of the room-temperature volatile substances and other additives in the carrier of the present invention, there are no particular limitations on the retention means and the timing of application of the means. In general, the above-mentioned holding means can be exemplified by the usual impregnation method, coating method, spraying method, etc., and the application period can be exemplified at any time such as the component stage before the manufacture of the animal house, the stage of the constructed animal house product stage, etc. In addition, when the carrier to hold the room-temperature volatile substance of the present invention is wood, in addition to the above, for example, appropriate holes are made in the carrier, and a solvent solution of the room-temperature volatile substance and other additives is poured into the hole. It is also possible to employ means of injection. When the carrier is a synthetic resin, the above-mentioned room-temperature volatile substances are kneaded into the molding raw material at the manufacturing stage, that is, at the time of molding the carrier.
It is also possible to support the room-temperature volatile substance in advance on a suitable carrier such as silica, and then mix it into the molding raw material. Furthermore, the silica etc. on which the room-temperature volatile substance is supported in the resulting synthetic resin member can be used. It can also be embedded.

The carrier holding the room-temperature volatile substance 1q in this way can be used as it is as an insect-proof dog house or animal house of the present invention if the carrier is in the form of an animal house, or if the carrier is a component of an animal house. An insect-proof shed of the present invention can be obtained by constructing an animal house using this in a conventional manner. Furthermore, the above-mentioned carrier holding the sexual substance of the present invention can be processed into a sheet form such as a carpet, flooring material, wall material, or other suitable form, and laid on the inner surface of an existing animal house. It can also be applied by appropriate means such as adhesion, pasting, hanging, etc. Even by applying the carrier in such a form to pet housing, the present invention can be applied in the same manner as the insect-proof dog house or animal house of the present invention. The excellent pest control effect of the invention was achieved by 1q.

Effects of the Invention The insect-proof shed of the present invention obtained in accordance with the above does not have repellency to pets, and the paper action of the specific room-temperature volatile substance used therein prevents pests such as fleas, ticks, and other mites that parasitize pets. In addition to being able to control flying pests such as insects and mosquitoes extremely efficiently, the durability of the shed itself is also improved, making it extremely useful.The present invention not only provides such a useful animal shed, but also provides the following benefits: It also provides a novel pest control method.
