JPH01319401A - Extermination of white ant - Google Patents

Abstract

PURPOSE:To form a receiving hole in a wooden attractor, inserting a detector into the receiving hole, laying the attractor in the ground, examining the detector at proper time intervals and, when the presence of white ants is confirmed, exchanging the inserted detector with an ant-exterminating agent to exterminate the white ants. CONSTITUTION:A receiving hole 2 is formed in a wooden (e.g., pine tree or Japanese cedar) attractor 1 and a detector 3 is inserted into the hole. The wooden attractor 1 is laid in the ground in a region having a possibility of white ants lying there. Totally >= eight of the attractors are preferably laid in the ground near an entrance, kitchen, toilet, bath room, other corner portions of a house, etc. The detector 3 is taken out from the attractor 1 and the presence of the white ants or the existence of traces eaten by the white ants is checked at least two - three times a year. When the presence of the white ants is confirmed, a slow-acting and non-repellent ant-exterminating agent is put in the receiving hole in an amount of 60-80% and the hole is, if necessary, stopped with a wooden stopper and further covered with a cover 4. The ant- exterminating agent is carried by the white ants to their nest ant and the nest is soon destroyed.

Description

[Detailed Description of the Invention] [Industrial Application Field] Architectural structures made of wood etc. may suffer from corrosion damage due to white matter, but in the case of houses, the damage rate is between 40% and 50%.
It is said to exceed the percentage.

In particular, modern wooden houses tend to use wood that has a small cross-sectional area, is not sufficiently dried, and has a low floor structure, making them more susceptible to damage from whitening.

The present invention relates to a method for detecting white spots around a wooden building and then injecting a pesticide to exterminate the white spots.

[Conventional technology]

Conventional methods for exterminating white ants have involved coating or injecting repellent pesticides onto wood or soil to avoid access of white ants to building structures.

[Problem to be solved by the invention]

The above method reduces the effectiveness of the pesticide due to aging,
After a certain period of time has elapsed, it is necessary to reapply or inject the pesticide again. However, in general, if a pesticide is applied or injected at the time of new construction, it is often left untreated until it suffers from feeding damage.

Although this method can avoid the approach of white ants, it cannot kill or injure them.

Therefore, the present invention aims to eliminate white spots that exist around architectural structures.
The goal is to detect white ants before they invade architectural structures and destroy their nests.

[Failure 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, and bury it underground.
Dosho Kanai Society φ Hand Hitomi, inspect the detector, and if there are white spots on the attractant or detector, and if there are food marks due to white spots or other traces of life with piles, remove the detector and store it. This method of exterminating white ants involves putting a white mite repellent or a substance containing a white mite repellent into the hole to exterminate the white ants.

As the attractant, a material that is preferred by white ants should be selected, and pine and cedar wood are particularly good.

Although the shape of the attractant is not particularly limited, cylinders, prisms, etc. are preferable.

The diameter (or width) and length of the attractant are not specified, but for example, the diameter is around 100 m, the length is around 300 m, and the attractant storage hole is a cylindrical hole with an inner diameter of 30 m +++ The thickness of the bottom of the hole is around 10 mm.

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 degrees.

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.

The pesticide is poured into the storage hole after the detector is pulled out, and the amount should preferably be about 60 to 80% of the volume of the storage hole.

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 is made of wood, which 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, they move the attractant along the growth rings from the bottom of the attractant, that is, from the mouth surface. will invade.

Inspect the placed detectors 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,
Predicting damage to the wooden building and estimating the invasion route of white ants, etc. Based on this, a slow-acting, non-repellent white ants insecticide is injected 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 return to its nest.

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

White ants have a habit of cleaning themselves of foreign substances that have adhered to their bodies, cleaning the bodies of other white ants, and 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〕

The present invention will be described in detail below based on the drawings.

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

The detector 3 has a rod shape (cylindrical shape) as shown in FIG. 1, and is made of pine or cedar.

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

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

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 Shield 4
cover with

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. can.

〔Effect of the invention〕

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