Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a repellent and method for repelling mites, particularly indoor mites such as mites and house dust mites that cause harm when they occur inside houses. is a repellent containing as an active ingredient one or more selected from isobonylthio V anoa heptatate, ortho-phenylphenol/%/, o-tophenylphenol alkali salts, dehydroacetic acid, and dehydroacetic alkali salts. Then, add and apply this to the target object (the object that should be prevented from generating or breeding mites).

This relates to a method for repelling mites by applying treatments such as impregnation to prevent mites from adhering to them.

In recent years, the damage caused by indoor mites has increased significantly as house structures have become more airtight and heating installations have become more widespread, allowing them to proliferate to a certain extent even in the winter.

Other factors that are thought to be contributing factors to the increase in damage include not doing much cleaning recently and not exposing bedding to enough sunlight.

Of these, woolly mites can be found in large numbers in reinforced concrete houses, etc., which are kept closed for a long time before the tenant moves in, and even after the tenant moves in, the indoor humidity remains high during the rainy season. The things that had grown on the ground started crawling out.

caused unpleasant harm to the occupants. In addition, the number of mites, which are the predators of mites, has increased, and their bites have become more harmful to humans.

On the other hand, dust mites are most commonly found in the indoor dust of schools and homes, and often make up the majority of the dust mites.The damage caused by dust mites is said to be the cause of allergies, etc., and their prevention and treatment are essential. Therefore, paper and fiber products containing insecticides are known.

The use of repellents is a safe and economical method, and the known repellents for insects and mites include 11,
N-diethyltoluamide, 2. ? +, 4゜5-via (delta-butylene) tetofhydrofurfur tool,
Sheets: Maru-globyl isocincomeronate, di-normal fluorophyl succinate, 2-hydroxyethyl octoxide, pyrimidine derivatives, phthalic acid esters, piperidine derivatives, xanthate conductors, acehine derivatives, pipecoline derivatives, 7p Folin derivatives, pyrrolidine derivatives, quinone dihydric alcohols, glyco-ethers, or octac-di-10-vinyl ether, biveronyl ptoxide, -2,5 dicarboximide, 1i-(2-ethyloxy/L/)-
1-inpropyl/I/-4-methylbicyclo[2,2,
2]] Octo-5-ene 2,3-dicarboximine is an example, but at present no product with satisfactory efficacy has been obtained for indoor mites.

In view of the above-mentioned circumstances, the present inventor has conducted extensive research and found that one or two selected from the group consisting of inbonylthiocyanoacetate, otophenylphenol, orthopheny/I/phenol alkali salts, dehydroacetic acid, and dehydroacetic acid alkali tombs. The present invention was completed based on the discovery that more than one species of mites are extremely effective in repelling mites.

That is, the present invention provides inbonyl thiocyanoacetate,
A da=i repellent containing one or more active ingredients selected from orthophenylphenol, an alkali salt of orthophenylphenol, dewFo acetic acid, and an alkali salt of dehydroacetate, and the repellent used to protect against mites. The present invention provides a method for repelling ticks S, which is characterized by applying, spraying, or containing the product on an object to be protected from being collected.

To carry out the method of the present invention, the active ingredient is applied to an object or its surroundings where mites tend to grow or inhabit, or the active ingredient is dissolved or emulsified in a solvent such as ethyl alcohol or xylol.

All you have to do is formulate it according to the usual method, apply it, spray it, or contain it, and target or surrounding objects include rugs such as tatami mats, carpets, house flooring, closets, and feed in general! Furniture such as h-bag, n-7a, etc. can be mentioned.

In addition, in order to contain the active ingredient, it can be used not only by including it in fibers and resins, but also by including it in advance in size liquid and paint.The content varies depending on the processing method, but 0.05F/ It goes without saying that the method of the present invention can be used in combination with a repellent.

The repellent and repellent method of the present invention exhibits a much higher repellent effect than the methods using known repellents as described above, and also has advantages such as long-lasting efficacy, economical efficiency, safety, and non-drug resistance. It is advantageous in this respect.

The present invention will be explained below with reference to Examples.

51! Example 1 A solution of ethyl alfur containing the active ingredient of the present invention was applied to kraft paper for chicken feed bags, cut into diameter SaI pieces, and woolly mites were left on the paper. # Five species were placed in a container, and the adhesion situation was predicted with a sullen look after 24 hours rKJ. As a result, as shown in Table 1, the Khufu 7F paper coated with the active ingredient of the present invention had significantly fewer mites (R).

Table 1* Number of mites in 1d -0++ 11~5°± 5 or less 100+ 51 or more + 5~10 Example 2 Ortho 7z2A, the active ingredient of the present invention, was applied to the surface of the tatami floor.
A tatami mat was sprayed with phenol and a solution of N,N-dimethyltriamide as a control at a ratio of 21/kg of active ingredient, and two untreated tatami mats and two tatami mats each were applied to a 6-tatami mat in a reinforced concrete apartment building. Lay it open,
To humidify the room, a bowl of water was placed on the tatami mat and the room was closed off. After 5 months and 5 days of P5, I placed 3 petri dishes filled with water on the tatami mat for observation.

After 24 hours, check the number of mites floating on the water surface! I counted under the mirror. As a result, as shown in Table 2, the number of goo in the petri dish placed on the tatami mat treated according to the present invention was significantly smaller than in other dishes.

! j! Example 3 An ethyl alcohol solution of sodium dehydroacetate was sprayed on the surface of a sofa covered with cloth at a ratio of 1 tlP of active ingredient/filter, and the untreated product was placed in a living room.

After 6 months, a suction-type vacuum cleaner was applied, and the collected dust was added to saturated saline and stirred, and the dust mites were separated from the dust, filtered with suction, collected on F paper, and counted under a microscope. As a result, as shown in Table 5, the number of mites adhering to the sofa 5#C, treated according to the present invention, was significantly less.
