Description

  The present invention relates to a termite control method and a termite creeping prevention induction sheet used therefor.

  Conventionally, as a method of preventing damage due to the invasion of termites (especially subterranean termites), chemicals are sprayed on the soil surface under the building floor, or chemicals are injected or sprayed onto wood such as pillars and foundations. It is common. Moreover, there existed the idea which installed the sheet | seat containing a transpirationable termite control component in a building member, and made the termite control component evaporate from there, and prevented the entry of a termite (for example, refer patent document 1 and patent document 2).

  However, since the termite movement route cannot be specified in advance, the conventional method described above cannot prevent invasion at a place where the chemical treatment is insufficient. For this reason, in order to control termites, there was a problem that a large amount of drugs had to be used. In addition, since the worker is forced to perform chemical treatment work in a closed space under the building floor, there is a problem that even if the protective equipment is worn, the safety problem remains even if the worker is exposed to the risk of exposure. In addition, the residents may feel uncomfortable due to the effect of the ant repellant that evaporates, the solvent used, etc. due to the use of the transpirant ant repellant.

  A main object of the present invention is to provide a termite control method capable of safely and effectively controlling termites with a minimum amount of medicine and a termite scooping prevention guide used therefor.

In the present invention, first, a sheet-like material formed by applying or mixing a termite repellent having a vapor pressure of 1.0 × 10 ⁻⁶ hPa or less is attached to a building member constituting the building, and the termite creeps up. It is a termite control method characterized by preventing.

  Eleventhly, the present invention is the above-described method for removably attaching a sheet-like material.

  Twelfth aspect of the present invention is the above-described method in which a sheet-like material is a roll-like sheet having an adhesive on one side and a release paper on the surface, and adheres to a building member while peeling the release paper at the time of use. It is.

In the thirteenth aspect of the present invention, a termite repellent having a vapor pressure of 1.0 × 10 ⁻⁶ hPa or less is mixed or applied on one side, and an adhesive layer and a release paper are arranged in that order on the other side. This is a termite creeping prevention induction sheet obtained by rolling a long belt-shaped plastic sheet.

  According to the present invention, the termite is not controlled by the chemical treatment on the soil surface or the xylem surface that requires a large amount of the drug, but in the form of a sheet containing a termiticide that is repellent to termites. By installing it in a place that is estimated to be the termite's movement route, the termite's movement is controlled to prevent the termites from entering the building material, and the termite control agent is guided to kill the insect. Termites can be controlled stably and effectively with a limit amount of drugs.

In the present invention, a termite repellent having a vapor pressure of 1.0 × 10 ⁻⁶ hPa or less is applied to a base of a building, a base, etc. It has been found that the creeping prevention and the guidance guide effect can be demonstrated to a high degree.

Further, by including a termite repellent having a vapor pressure of 1.0 × 10 ⁻⁶ hPa or less, it can remain in the sheet-like material for a long time and prevent the entry of termites.
As the termite repellent used in the present invention, any drug can be used as long as it has a repellent vapor pressure of 1.0 × 10 ⁻⁶ hPa or less.

Specific examples include pyrethroids such as bifenthrin (2.4 × 10 ⁻⁷ hPa, 25 ° C.), permethrin (6.8 × 10 ⁻⁹ hPa, 25 ° C.), cypamethrin (4.1 × 10 ⁻¹¹ hPa). , 20 ° C.), alpha cypamethrin (4.1 × 10 ⁻¹¹ hPa, 20 ° C.), zeta cypamesulin (2.5 × 10 ⁻¹¹ hPa, 25 ° C.), non-ester pyrethroids: 0.5 × 10 ⁻⁸ hPa, 20 ° C.), natural product type: for example, pyrethrin (5.3 × 10 ⁻⁷ hPa, 25 ° C.) and the like.

In the present invention, pyrethroids are more preferred, and bifenthrin is particularly preferred among them.
Examples of the sheet-like material used in the present invention include a plastic sheet, non-woven fabric, paper, wire mesh, metal sheet and the like, and a plastic sheet is particularly preferable.

  Examples of the plastic that is the base material of the plastic sheet include thermoplastic resins such as polyester, polyethylene, ethylene vinyl acetate resin, and vinyl chloride resin.

  These sheet-like materials may be coated with a termite repellent on one surface thereof when it is impossible or undesirable even if the termite repellent is kneaded and mixed when molding the sheet-like material. it can. In application, an appropriate binder (adhesive) can be used in combination for adhesion. The concentration of the termite repellent is usually about 0.00002 to 2%, and it shows an inhibitory effect not only on termites but also on pests such as ants, centipedes, and rubber bugs.

These sheet-like materials are usually attached (installed) at predetermined positions on the building member as belt-like sheet-like materials having a width of 2 mm to 50 cm and a thickness of 0.01 to 2 mm.
The installation location is preferably the vertical surface of the building member near the floor under the building and / or the back surface (lower surface) of the floor structure.

  Examples of vertical surfaces include concrete foundations, foundations, boulders, floor bundles, roots, large draws, joists, firebeds, water supply and drainage pipes, electrical wiring, etc. Examples of back surfaces (bottom surfaces) include floor boards, There are undersides such as foundations, boulders, floor bundles, gallows, large draws, joists, firebeds, water supply and drainage pipes, and electrical wiring.

  The sheet-like material is installed so as to prevent the termites from creeping up due to the presence of the sheet-like material and to function as a guide for guiding the termites. For example, the above-mentioned function can be effectively shown by installing continuously in the horizontal direction with respect to the vertical plane. Termites move in all directions while detecting food such as wood, but if there is an obstacle in the direction of travel, there is a habit of moving along the edge of the obstacle. For this reason, when an object that obstructs movement is placed in the movement range, the object moves along the obstacle. This termite's movement behavior is used to prevent the termites from creeping up and to install the termites. Usually, it is installed at a position not in contact with the floor baseboard surface, preferably at least 5 cm away from the lower end.

  It is desirable that the sheet-like material is adhered to the building member so that no voids permitting the entry of termites are formed between the surface of the building member and the building member is usually constructed using an adhesive (including an adhesive). Adhere to the member.

  As the adhesive, a conventionally known appropriate adhesive can be used. Specific examples include asphalt, acrylic resin, a-olefin, urethane resin, epoxy resin, ethylene-vinyl acetate resin emulsion, ethylene-vinyl acetate resin, hot melt epoxy resin, vinyl chloride resin solvent system. And chloroprene rubber-based, cyanoacrylate-based, silicone-based, aqueous polymer-isocyanate-based, styrene-butadiene rubber solution-based, nitrile rubber-based, and polyvinyl acetate resin solution-based adhesives. In addition, it is preferable to mix a termite repellent in the adhesive.

  Moreover, when the building member which comprises a to-be-adhered surface is a building member with absorbency, such as a wooden member, a heat insulating material, and a concrete foundation, it is desirable to use the adhesive agent which has the permeability | transmittance to them. Specific examples of such permeable adhesives include adhesives such as asphalt, acrylic resin, urethane resin, epoxy resin, and chloroprene rubber.

When using the adhesive, it is desirable to select an adhesive that can remove the sheet-like material after long-term use.
As the sheet-like material used in the present invention, it is desirable to use a sheet wound in a long strip shape in which a sticky adhesive is previously applied to a surface to be attached to a building member and a release paper is arranged thereon. In particular, when constructing an already constructed building, it can be installed more easily and accurately by installing it while peeling the release paper. Also, at that time, the use of auxiliary tools that assist in rotating the roll, supporting the roll, separating the sheet, and assisting in the installation position of the sheet can further facilitate work in a narrow place such as under the floor. Can do.

Due to the presence of the sheet-like material of the present invention, the termite is controlled to move without crawling on it, and moves along the lower end of the sheet-like material. Therefore, the termites can be effectively controlled by inducing the moving termites to the termite control agent. As the termite-controlling agent, a conventionally known appropriate termite-controlling agent (insecticide, poison bait, etc.) can be used, and by placing containers containing the termite-controlling agent at a predetermined position to be guided, Colonies can be destroyed. Specific examples of termite control agents include insect growth inhibitors such as diflubenzuron (1.2 × 10 ⁻⁹ hPa, 25 ° C.), teflubenzuron (1.3 × 10 ⁻¹⁰ hPa, 25 ° C.), hexaflumuron (5 .9 × 10 ⁻¹¹ hPa, 25 ° C.), Novallon (1.6 × 10 ⁻⁷ hPa, 25 ° C.), Rufenuron (4.0 × 10 ⁻⁸ hPa, 25 ° C.), Flufenuxuron (4.5 × 10 ⁻¹⁴ hPa, 20 ° C.), chlorfluathlon (1.6 × 10 ⁻⁸ hPa, 20 ° C.), debufenozide (3.0 × 10 ⁻⁸ hPa, 25 ° C.), chromafenozide (4.0 × 10 ⁻¹¹⁾ hPa, 25 ° C.), methoxyfenozide ^{(1.3 × 10 -7 hPa, 25} ℃), Jiromajin ^{(4.2 × 10 -7 hPa, 20} ℃), neonicotinoid agents, for example A Tamipurido ^{(1.0 × 10 -8 hPa, 25} ℃), imidacloprid ^{(2.0 × 10 -9 hPa, 20} ℃), Chiamesokisamu ^{(6.6 × 10 -9 hPa, 25} ℃), clothianidin (1.3 × 10 ⁻¹² hPa, 25 ° C., dinotefuran (1.7 × 10 ⁻⁸ hPa, 30 ° C.), nitenpyram (1.1 × 10 ⁻¹¹ hPa, 20 ° C.), thiacloprid (8.0 × 10 ⁻¹² hPa) , 25 ° C.), as examples of other drugs, pyrrole series: eg chlorfenapyr (1.3 × 10 ⁻⁷ hPa, 25 ° C.), phenylpyrazole type: eg fipronil (2.0 × 10 ⁻⁸ hPa, 25 ° C.) , ethiprole ^{(9.1 × 10 -10 hPa, 25} ℃), oxa diazinon system: e.g. indoxacarb ^{(4.0 × 10 -12 hPa, 25} ℃), It can be exemplified.
