Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling pests, a pest control material and an underfloor structure.
More specifically, a pest control method that can be reliably removed with simple construction and does not harm human bodies or pets,
It relates to pest control materials and underfloor structures.

[0002]

2. Description of the Related Art Pests such as termites, cockroaches, slugs, and hundred feet are easily invaded under the floor of buildings such as houses. It was unsanitary because it invaded the kitchen or living room from under the floor and spread bacteria. In particular, when termites enter under the floor or the like, they damage the wooden members of the building, reduce their strength, and cause serious damage such as shortening the life of the building. In any case, it is necessary to eliminate the above-mentioned pests from entering the underfloor and the like, and the following extermination method is usually employed. One is a method in which a pesticide such as an organic phosphorus compound is used as an emulsion and sprayed on soil under the floor. The other one is
This is a method in which a hole is drilled in a wooden member of a floor set such as a floor, a large-scale floor, a joist, and the like, filled with an organophosphorus pesticide, and plugged with a cork or the like. This method is generally used for controlling termites and the like. However, in the former method, if the ventilation is not sufficiently good, moisture is trapped under the floor, causing the wooden members of the floor group such as the floor, the large-scale and the joist to rot. Further, in the latter method, there is a possibility that the strength of a wooden member of a floor group such as a floor, a large floor, a joist or the like may be reduced due to the opened hole, and the life of the building may be shortened. Further, in any of the above methods, there is a possibility that harmful gas is generated from the organophosphorus pesticide or the like as time passes, and the harmful gas enters the room and causes toxic symptoms to humans and pets.

Therefore, in consideration of the above-mentioned problems, for example, an effective extermination method for termites has been considered.
One of the methods is to use a repelling action of copper by wrapping a copper plate on the side and underside of a wooden member of a floor group such as flooring, pulling, joist and the like. Another method is to use a copper tape in place of the copper plate and use the repelling action of copper in a similar manner.

[0004]

However, in the former method, when a building is already existing, considerable skill is required to accurately wind a copper plate on the side and lower surfaces of a wooden member of a floor set. . For this reason, a gap or the like is often formed between the side surface of the copper plate and the wooden member of the floor group or between the lower surface and the upper surface of the foundation, and there is a risk that termites will enter from the gap and eat the wooden member of the floor group. was there. In particular, when winding a copper plate on a portion of the lower surface of the wooden member that is in contact with the foundation, it is necessary to lift the wooden member, and it has been difficult to wind the copper plate on the lower surface. Also, in the latter method, the copper tape is more easily deformed than the copper plate. Therefore, it is somewhat easier to wind the copper tape around the side surface of the wooden member of the floor set as compared with the former method. However, similarly to the former method, a similar gap is formed in the same place, and there is still a risk that termites may enter the gap and eat and erode wooden members of the floor set.

The present invention has been made to solve the above-mentioned problems, and includes a method of including a termite of a wooden member such as a floor of a building by a simple method without any skill even if the building is already installed. It is an object of the present invention to provide a pest control method, a pest control material and an underfloor structure capable of reliably preventing damage caused by pests.
