Description

[Detailed Description of the Invention] [Industrial Application Field] Architectural structures made of wood etc. may suffer from damage caused by white matter, but in the case of residential buildings, this damage rate exceeds 40% to 50%. It is said that.

In particular, modern wooden houses tend to use wood that has a small cross-sectional area and is not sufficiently dried, and the structure of the house has a low floor space.
Easily susceptible to damage from white ants.

The present invention detects white spots around wooden buildings,
The invention relates to a method for exterminating white ants by subsequently introducing a repellent.

[Conventional technology]

The conventional method of exterminating white mites uses repellent pesticides,
It was applied or injected onto wood or soil to prevent white ants from accessing building structures.

[Problem to be solved by the invention]

In the above method, the effectiveness of the pesticide decreases over time, and after a certain period of time has elapsed, it becomes necessary to reapply or inject the pesticide. However, in general,
When a pesticide is applied or injected at the time of new construction, it is often left untreated until it is damaged by white ants.

Also, with this method, although it is possible to avoid the approach of white ants, it is not possible to kill or injure white ants.

Therefore, the object of the present invention is to detect white ants existing around a building structure before they invade the building structure, and to destroy the nest of white ants.

[Means to solve the problem]

The gist of the present invention is to provide a storage hole in an attractant made of wood, insert a detector into the hole, bury it underground, inspect the detector, and check whether the attractant or the detector is white. If the presence of white ants, feeding marks due to white ants, or other traces of the life of white ants are observed, remove the detector and inject a white ants exterminator or a substance containing a white ants into the storage hole to exterminate the white ants. This is a method of getting rid of white ants.

As the attractant, a material that is preferred by white ants should be selected, and pine and cedar wood are particularly good.
Further, the shape of the attractant is not particularly limited, but cylinders, prisms, etc. are preferable.

Although the diameter (or width) and length of the attractant are not specified,
For example, the diameter is around 100 mm, the length is around 300 mm, the attractant storage hole is a cylindrical hole, and the inner diameter is around 100 mm.
It is around 30mm, and the thickness of the bottom of the hole is around 10mm.

The detector is made of wood such as pine or cedar, and has a rod shape such as a cylinder or a prism, although its shape is not particularly limited. It is desirable that the difference between the outer diameter of the cylindrical detector and the outer diameter of the cylindrical detector be approximately 2 mm.

The shield is made of mortar, synthetic resin, etc., has a disk shape, for example, and is provided with a recess inside so as not to interfere with the detector.

As the white mosquito repellent, a slow-acting and non-repellent repellent is used.

Remove the detector and put the pesticide into the storage hole, but the amount should be around 60% to 80% of the volume of the storage hole.

Also, if necessary, after adding a pesticide, seal the storage hole with a stopper made of wood or the like.

[Effect]

The present invention has a method as described above, but first, an attractant or the like is placed underground in an area where there is a possibility that white spots may exist, for example, around a wooden building structure. This placement can be done when a new wooden building is constructed. As an example of placement, in the case of a general house, it is recommended to bury a total of eight or more locations underground near the entrance, kitchen, toilet, bathroom, and other corners of the house.

The attractant has a woody texture that white ants prefer, so it has the effect of attracting the surrounding white ants, and when the white ants have a habit of invading the attractant, the attractant moves along the growth rings from the bottom of the attractant, that is, from the mouth surface. will invade.

Inspect each placed white detector at appropriate time intervals. Inspect at least two or three times a year.
Be sure to check especially between spring and autumn. For inspection, the detector is pulled out from the attractant and checked to see if there is white on the inside of the attractant or on the detector, or if there are any signs of eating damage caused by the white.

As a result of the inspection, if no white spots or feeding damage marks due to white spots are found, place the detector in the same position as last time. If there is white or damage caused by white on either or both of the attractant and the detector, conduct a detailed investigation to determine which position of the detectors has been damaged and to what extent. , write the results on the floor plan of the wooden building, estimate the expected damage to the wooden building and the invasion route of white ants, and use a slow-acting, non-repellent white ants insecticide based on this. Insert into the storage hole. After loading, plug the storage hole if necessary, and then cover it with a shield.

On the other hand, even if a white ant ingests a pesticide or has a pesticide attached to its body surface, the white ant will not die immediately and will simply return to its nest.

In other words, the white ant carries the pesticide to its own nest.

White people clean themselves of foreign substances attached to their bodies, clean the bodies of other white people, and
They have a habit of exchanging nutrients.

Due to this interaction between the white ants, the insecticide spreads within the nest, which eventually kills the reproductive insects (the queen of the white ants and others) and destroys the nest of the white ants.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 1 and 2, a cylindrical attractant 1
Provide a storage hole in the core. The storage hole has a circular cross section. As the material of the attractant 1, pine or cedar wood is used.

The detector 3 is rod-shaped (cylindrical) as shown in Figure 1.
The material used is pine or cedar.

As shown in FIGS. 1 and 2, the shield 4 has a concave portion 7 formed on the lower side and has a circular plane.

Next, the detector 3 is stored in the storage hole 2 of the attractant 1 and received at the bottom 8.

After that, it is buried in the ground G in the area where white spots are to be detected and exterminated, and the shielding body 4 is placed on top of this.
An example of burial is shown in Figure 3.

The arranged detector 3 is inspected periodically. As described above, the inspection is performed from the viewpoint of whether there is white in the housing hole 2 of the detector 3 or the attractant 1, and whether there are eating marks or the like caused by the white.

As a result of the inspection, if the presence of white or any trace thereof is not recognized, the detector 3 is placed again at the same position as last time.

On the other hand, if traces of the presence of white are found, pour powder of pesticide 5 (slow-acting, non-repellent) or a substance containing pesticide into the storage hole 2, seal the top with plug 8, and then Cover with shield 4.

As a result, the white ant ingests the insecticide 5 orally and the insecticide 5 adheres to its body surface, thereby achieving the same effect as spraying the insecticide 5 on the nest of the white ant. .

〔Effect of the invention〕

According to the present invention, white spots can be simply, easily, and completely exterminated.
