Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a repellent and a method for repelling mites, especially indoor mites and house dust mites that are harmful when they occur inside houses. is a repellent containing chlorinated metaxylenol and/or paraoxybenzoic acid ester compound as an active ingredient, and treatments such as spraying, adding, coating, impregnating, etc. with it on objects (objects to be prevented from generating or breeding mites). This relates to a method of repelling mites that prevents mites from attaching to them.
Due to the increased airtightness of fft structures and the introduction of heating systems in the past, it became possible for them to proliferate to a certain extent even in the winter, resulting in a significant increase in damage caused by these.

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

Among them, woolly mites are caused by reinforced concrete houses that are kept closed for a long time before the occupants move in, and also because the indoor humidity remains high even after the tenant moves in, such as during the rainy season.

Things that had grown in the tatami mats were crawling out and causing unpleasant harm to the residents.

In addition, the number of tick M4b, which is a prey of the white mite, increased.
It also caused a lot of harm because it stung people. .

On the other hand, Chillidae are generally found most often in the indoor dust of schools and homes, and often make up the majority of the dust. Paper and textile products containing insecticides are known.

The use of repellents is a safe and economical method, and the known repellents for insects and mites include N and B1.

In view of the above-mentioned tubes, the inventors of the present invention conducted extensive research and found that chlorinated meta-xylenol and/or.

The inventors have completed the present invention by discovering that puffoxybenzoic acid ester compounds are extremely effective in repelling mites.

That is, the present invention provides a mite repellent containing a chlorinated metaxylenol and/or a puff oxybenzoic acid ester compound as an active ingredient, and a method for applying, spraying, or containing the repellent on an object to be protected from damage by mites. The present invention provides a method for repelling mites characterized by the following.

Puffoxybenzoic acid ester compounds, which are one of the active ingredients of the present invention, include Patsuoki V5R-methyzoate, Patsuoki V ethyl benzoate, puffoxybenzoic acid butylate,
Puffed propylene benzoate, puffed oxybenzoate, etc. are used.

The method of the present invention is effective against the generation of goo, by applying the active ingredient to the object or its surroundings, which is likely to inhabit, or by dissolving or emulsifying the active ingredient in a solvent such as Kijirol.
4. It may be formulated by a conventional method and applied, applied to cloth, or contained. Examples of the object or surrounding objects include rugs such as tatami mats and carpets, flooring materials for houses, cages, feed/grain bags, and furniture such as sofas. In addition, the active ingredient can be contained not only in am or resin, but also in paste JP.
It may be included in the paint in advance. 6 Its content angle varies depending on the processing method, but it is desirable to include it at 0.05 f/n1 or more, and the method of the present invention can be used with other repellents. Needless to say, you can also do it.

According to the repellent and repellent method of Akira Kinki, the repellent effect is far superior to that of the methods using known repellents as mentioned above, and the effect is more durable.

It is advantageous in terms of economy, safety, FC resistance, etc.

The present invention will be explained in the following examples.

Example 1 Puff chloromethaxylenol α to the outer paper of a 7-ton bag of feed for rows.
Three bags coated at a rate of 5v~ were left in a warehouse where there were a lot of woolly mites, with two untreated bags as a control. After one month, 5 x 5 cm sections were cut from 5 locations on each bag, and the number of mites was counted under a microscope and the average value was calculated. As a result, as shown in Table 1, almost no mites were attached to the tA treated according to the present invention.

wS1 Table Example 2 Using 8B footwear mixed with the active ingredient of the present invention, a polypropylene primary base fabric was coated with acrylic/l/inner p'a.
Glue the wotufting to jute and then glue it to eight fabrics to make a carpet? l! Built. As a control, a substance known to repel insects and mites was treated at the same temperature (°f5).

Cut each piece into 5 x 5 d pieces and leave Rike-naga-konada-2 for 50
Five pieces were placed in a 20 x 10 cIl container, and the adhesion was quenched after 24 hours. As a result, as shown in Table 2, there was almost no adhesion of mites to the products using the repellent of the present invention.

The surface of the tatami floor was sprayed with puffed chloromethaxylenol, which is the active ingredient of the present invention, and a Kinrol solution of N,N-diethyltriamide at °C as a control at a ratio of 27/d of the active ingredient, and then the tatami surface was attached.

They laid two untreated tatami mats and two reinforcing steel concrete tatami mats in the 6 tatami room of their apartment building, placed two containers of water on top of the tatami mats, and closed off the room.

After 5 months and 5 months, six petri dishes each filled with water were placed on a tatami mat for observation, and 24 hours later.

The number of mites floating on the water surface was counted under a microscope.

As a result, as shown in Table 5, the number of mites in the Petri dish placed on the tatami mat treated with the present invention was significantly lower than in the other dishes.

'n 5s Number of mites in a petri dish (average of 5 mites) Example 4 Apply a solution of butyl puffoxybenzoate in ethyl alcohol to the surface of a cloth sofa Active ingredient: IN 19
It was sprayed at a rate of /d and placed in the living room along with untreated products.

After 6 months, use a suction vacuum cleaner, add the collected dust to saturated saline, stir, remove the dust mites from the gourds, suction, filter, collect on filter paper, and do it! 'I Counted under a microscope. That l? As a result, as shown in Table 4, the sofa treated according to the present invention had significantly fewer mites attached to it.
