Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides pests that are suctioned and captured using a vacuum suction cleaner,
Concerning methods for exterminating mites.

[Conventional technology]

In recent years, due to changes in lifestyle, more and more rooms are being carpeted, and highly moisture-absorbing tatami mats are also being laid on concrete floors, causing the occurrence of mites such as mites, mites, lice mites, and mites. However, this has caused problems such as discomfort. In particular, house dust mites, which are found in large numbers in indoor dust and all types of house dust, are said to be an allergen for inhalation allergic diseases such as childhood asthma and asthma, and are a problem. Furthermore, when dogs and cats are kept indoors, fleas and flea eggs may fall onto carpets, etc., and these fleas may cause biting disease.

Therefore, the above-mentioned mites, fleas, etc. are exterminated by suctioning them with a vacuum suction cleaner (hereinafter referred to as a vacuum cleaner). but.

Normally, the garbage in the dust collection bag of a vacuum cleaner is not thrown away until it is full of garbage, but in that case, the mites that are sucked in will breed in the dust collection bag and the dust collection bag will be filled with garbage. There is a possibility that it will come out. In addition, dead bodies of Dermatophagoides mites pass through the dust collection bag and are discharged together with the discharged air, causing a problem of asthma. In order to prevent this, it is possible to use a paper dust collection bag and throw it away every time you clean it, but this is expensive and takes time to replace, and it is difficult to kill pests and mites. Since it cannot be done, it cannot be called a fundamental extermination method.

Therefore, organic phosphorus agents (fenitrothion, diazinon, etc.) are used in disposable dust collectors of vacuum cleaners, so-called paper packs.
Recently, products coated with insecticides and acaricides have been developed. The paper pack coated with this insecticide and acaricide is attached to a vacuum cleaner and sucks in insects and mites, thereby killing insects and mites.

[Problem that the invention seeks to solve]

However, the method of exterminating pests and mites that uses paper packs coated with insecticides and acaricides as described above can only kill insects and mites that come into contact with the paper packs, and dust may remain. , when a large amount of garbage is sucked in, pests,
There is a problem in that mites cannot be killed or killed because they do not come into direct contact with paper packs coated with insecticides or miticides. Furthermore, since the insecticide and acaricide are only thinly applied onto the paper, there is a problem in that the insecticide and acaricide decompose over time.

The present invention is intended to solve the above-mentioned problem, and uses a dust powder containing an acaricide to kill pests and mites that have been sucked up with a vacuum cleaner and captured in a paper pack. The purpose of this invention is to provide a method for exterminating pests and mites that can be reliably exterminated even if they remain.

[Means for solving problems]

The method for exterminating pests and mites of the present invention involves injecting or suctioning a powder containing insecticides and acaricides into a paper pack for a vacuum cleaner, and then suctioning and trapping the insects and mites into the paper pack using a vacuum cleaner. It is characterized in that the powder is applied to the pests and mites.

According to the method of the present invention, a powder containing an insecticide or acaricide is introduced into a dust collection paper pack used for a vacuum cleaner before, after, and/or at the same time as sucking pests such as mites and fleas. Alternatively, the pests and mites trapped in the paper pack can be exterminated by suction using a vacuum cleaner.

The particle size of the powder used in the present invention is such that when the powder is sucked up by a vacuum cleaner, it dances in the paper bag that is a dust collection bag due to the air flow generated by the suction, and evenly contacts pests such as ticks and fleas. The particle size is preferably from 100 to 10 mesh, depending on the speed of the suction air flow.

In addition, house dust mites have a size of 0.2 to 0.4 layers and cause allergic rhinitis and asthma, but their dead bodies also act as allergens, and their bodies are even smaller.
It is necessary to prevent the carcasses from passing through the paper pack. Therefore, it is preferable to set the particle size of the powder to a size that does not pass through the openings of the paper pack and causes clogging of the paper towel, and such particle size depends on the size of the openings of the paper pack. It is preferable that the particle size is 300 to 100 meshes, and it is also preferable to use powders with the above two types of particle sizes in combination.

The paper pack used in the present invention is not only paper but also a dust collecting filter made of a porous sheet of non-woven fabric or synthetic resin.

'( is prepared by a conventional method together with a carrier. For example, clay, karyon, zeolite, etc. can be used as the carrier, and if desired, PAP may be mixed therein to improve slippage.

To make a vacuum cleaner suck up the powder, for example, you can tear the bag containing the powder and let the vacuum suck the powder into a paper pack, or tear a part of the paper bag containing the powder. It is also possible to use paper that is easy to use, place the suction port of a vacuum cleaner on the paper bag and apply suction to tear the paper, suction the powder in the paper bag, and finally suction the bag as well. A container containing powder is attached to the vicinity of the suction port of the paper pack of the machine, and the powder is sucked out from the opening provided in the container by the air flow generated when suctioned by a vacuum cleaner, and is dispersed. This method is preferable because it can be applied evenly to pests and mites.Also, the method of spraying the powder on the carpet or tatami mat to be cleaned and sucking it up with a vacuum cleaner along with the pests, mites, and dust is also preferable because the powder can be applied evenly to pests and mites. This is preferable because it mixes thoroughly and is collected on the paper pack.Also, before sucking up the dust mites, it is preferable to suck the dust and make it adhere to the paper pack in a film form, so that the dust mites, etc. This is preferred because it is captured on the powder.

The amount of powder to be applied is appropriately determined depending on the application target, application conditions, etc., but for example, when the powder is sucked or put directly into a paper bag, it is preferably 5 to 50 g, preferably 10 to 20 g. When the powder is dispersed and then sucked, the amount is preferably 5 to 30 g/rn'.

In addition, some pests, such as the Dermatophagoides mites, are very small, with a body length of 0.2 to 0.4 mm, and even if such small pests are sucked up along with paper scraps and dust, they may not reach the surface of the paper pack. Since the insecticides and acaricides are often trapped on the surface of the paper pack, it is preferable that the paper pack, that is, the dust collection bag, carry the insecticides and acaricides. A method of exterminating pests by sucking in pests and mites and then sucking in a powder agent can reliably exterminate pests of various sizes, so the preferred insecticides and acaricides to be carried in zero paper packs are:
Those used for the above-mentioned powders can be used, and the amount of active ingredient supported depends on conditions such as the size of the paper pack, but is preferably about 0.04 to 0.2 g per paper pack. Methods for supporting the active ingredient on a paper pack include applying a solution, emulsion, or rfA suspension of the active ingredient to the paper of the paper pack, dipping the paper in the solution, or double coating the paper. An example is a method in which powder is added between the two. In addition, before sucking in pests and mites, the powder may be sucked into a paper pack to form a film.Furthermore, if the entrance or side of one paper pack is loaded with an insecticide or acaricide,
Since there is not much dust embedded in the entrance or sides, pests and mites come into direct contact with these areas, so pests and mites in one paper pack are
It is possible to prevent mites from escaping from the entrance of the paper pack.

The extermination method of the present invention can be applied to carpets, rugs, clothes/tatami mats, and boards, and is not particularly limited to, but is applicable to, but not limited to, Dermatophagoides mites contained in house dust.

It is effective in exterminating woolly pests such as woolly mites, claw mites, dust mites, lice mites, burs, carp moths, Japanese carp moths, and Japanese carp bugs, as well as fleas, bedbugs, and dust mites from livestock, etc., and is effective against larval, nymph, and adult stages. Of course, it also exhibits a hatching inhibiting effect, and is also effective in exterminating grain storage pests such as cockroach nymphs and grain weevils.

[Effect]

Since the pests and mites are sucked with a vacuum cleaner and captured in a paper bag, which is a dust collection bag, pests and mites can be easily and reliably captured. And/or at the same time, a powder containing an insecticide or acaricide is applied by suction or injected into the paper pack, so the powder acts on the pests and mites to easily and reliably exterminate the pests and mites. can.

〔Example〕

The present invention will be explained in detail by examples.

Test example 1. Extermination effect test A paper pack was attached to an electric cleaner Im (suction power tsow), and acaricide powder 1 containing 1% α-7 enothrin was applied.
0g was sucked for 2 minutes to spread the powder thinly on the inner wall of a paper pack.Next, a medium containing about 5,360 crucian carp and Dermatophagoides was sucked out at a temperature of 25°C and a relative humidity of 75%.
It was left under these conditions for 3 days. Thereafter, the paper pack was cut open, the mites were collected, and the mites were separated using a saturated saline suspension method, and the number of mites was counted. As a comparative example, a paper pack whose inner surface was coated with fenitrothion was used. The results are shown in the table below.

In the table, almost all the mites in the medium were recovered, including the number of dead mites.

As can be seen from the test results, the extermination method of the present invention has an excellent extermination effect on Dermatophagoides mites, and the growth inhibition rate is 100%.
Met. On the other hand, it was not possible to obtain sufficient effects using paper packs coated with fenitrothion alone.

Example 1 A vacuum cleaner equipped with a paper pack containing 1% fenitrothion as an active ingredient, using clay as a carrier,
By tearing a paper bag containing 5 g of powder having a particle size of 20 G mesh and 40 mesh, sucking up the powder and spreading it thinly on the paper bag, and then cleaning a 6 tatami-sized carpet that had been infested with Dermatophagoides nigricans. The mites were sucked up along with dust and the like. After 3 days, the survival rate of Dermatophagoides mites in the paper pack was examined and was found to be less than 1%.

Example 2 Carrion powder was used as a carrier, and permethrin 0.5% and I
10 g of a powder containing 0% BTAl and having a particle size of 300 mesh and 20 mesh was spread, and the powder was sucked up using a vacuum cleaner equipped with a paper pack, and at the same time, the mites, dust, etc. were sucked into the paper pack. When the survival rate of mites in the paper pack was examined after 3 days, it was less than 1%.

Example 3 A vacuum cleaner equipped with a paper pack was used to clean a 6-tatami-sized tatami mat where mites had grown, and the mites were sucked into the paper pack along with dust. 100 mesh powder lag containing 5% and 0.5% diazinon, 5% PAPo for good slippage and zeolite powder as carrier.
The suction port 3 of the vacuum cleaner is applied to a paper bag l as shown in FIG. After suction was applied to the paper bag, the pressure by the suction port 3 was removed and the paper bag was also suctioned.

After 3 days, we checked the survival rate of mites in the paper pack and found 1
% or less. In addition, the mites did not come out of the paper pack.Example 4: 0.04 g of fenitrothion and 0.0 g of sanophenothrin
Using a vacuum cleaner equipped with a paper pack coated with 4g, a 6-tatami-sized carpet in which the Kona hypodermic mites had grown was vacuumed, and the mites were sucked into the paper pack along with dust, and then used in Example 3. 10 g of powder was aspirated in the same manner as in Example 3. When the survival rate of mites in the paper pack was examined after 3 days, it was less than 1%.

Example 5 A powder container 7 attached to the periphery of the suction port 5 of the paper pack 4 and opened to the suction port 5 as shown in FIG.
Vermetri ″′ filled with °5%・IBTAI°
A paper pack 4 containing 20 g of powder of 0%, Bp"tvyse*, 10G mesh was attached to a vacuum cleaner.
I vacuumed and cleaned the tatami mats. The dust mites and dust were sucked, and the powder 6 was also sucked out from the discharge port 8 of the powder container 7 by the air flow generated by the suction, and was sufficiently attached to the dust mites. When the survival rate of mites in the paper pack was examined after 3 days, it was less than 1%.

Example 6 5 g of a 200-mesh powder consisting of 1% fenitrothion and clay was vacuumed and deposited thinly on a paper pack. Next, the fleas were sucked out by cleaning a half-tatami-sized carpet that had fleas on them, and then 50 mesh powder of 1% phenothrin and clay was applied.
5g was aspirated for several minutes. One day later, the flea survival rate in the paper pack was examined and found to be 0%. Furthermore, no fleas escaped from the paper pack.

〔Effect of the invention〕

As described above, the present invention provides a method of suctioning with a vacuum cleaner using a powder containing a film-forming acaricide in a paper pack,
Since the pests and mites trapped in the paper pack are exterminated, the pests and mites can be easily exterminated, and the extermination effect is excellent.
Pests and mites do not come out of the paper pack, making it extremely practical.

Furthermore, the exterminated pests and mites can be disposed of along with the paper pack, which is convenient.

Furthermore, since pests and mites do not breed in the paper pack, there is no problem even if you leave the paper pack attached to the vacuum cleaner until the paper pack is full of dirt and dust. There is no need to dispose of paper packs, which is hygienic and allows paper packs to be used effectively.

Furthermore, it has many advantages, such as being able to prevent the carcasses of Dermatox mites from being redispersed, which act as allergens.
