JP6924345B2 - Termite extermination method using crystallization of disodium octaborate tetrahydrate powder - Google Patents

Description

The present invention relates to a new method for preventing termite damage at the stage of building foundation work.

Conventionally, pesticide-based insecticides and soil treatment agents have been the mainstream of preservatives and termiticide, and even if the pesticide "based" is actually used, the pesticide itself is simply diverted for residential use. In building foundation work, these chemicals have been infiltrated into a part of the foundation concrete and used.
The crystal of 100% pure disodium octaborate tetrahydrate (hereinafter referred to as DOT) has a strong toxic active ingredient and contact poison, and has an effect of exterminating termites. Has been published.
In the foundation heat insulating method, a method of applying a solution of DOT to the foundation wall to which the heat insulating material is bonded is also known (see Patent Document 1). Further, there is also known a control method in which a base material such as a carpet is impregnated with a solution of DOT, dried, the crystals are coated on a diet, and the fleas and insects are brought into contact with the exoskeleton to kill them (Patent Document 2). reference).

Japanese Unexamined Patent Publication No. 2013-234484 U.S. Pat. No. 5,314,699

Pesticide-based preservatives and termites have a short effect of up to 5 years, and even if they are reprocessed, there are still many parts that cannot be treated. The state that is not strange will continue.
Even more problematic is that these drugs contain chemicals that cause allergies and sick building syndrome, and are volatile. Therefore, similar to the effects of formaldehyde used for furniture and indoor cloth upholstery, even under the floor, it invades and drifts into the living space where people live, and inhaling it causes similar health hazards. It ends up. Then, even if it has the effect of exterminating termites, it can exterminate even humans, and it is a complete fall as to what the treatment is for.
The method of infiltrating a part of the building foundation concrete, which has been widely used, with a termite extermination agent solution, the moisture generated from the foundation concrete itself stays under the floor and gradually infiltrates into the wall, and the moisture from the foundation to the house also It will continue to be supplied, and the environment for termite habitat will be guaranteed for the entire house through corrosion due to dew condensation inside the wall and propagation of decaying bacteria. On the other hand, if a waterproof material is applied to the surface of the infiltrated foundation concrete, the ant-proof construction will be ruined.
Therefore, we have installed equipment that keeps the temperature and humidity constant throughout the year, installed special equipment to prevent the humidity inside the wall from trapping, and installed a ventilation fan, but what is a drastic measure? is not.
The prior art shown in Patent Document 1 will offset the anti-termite effect by the amount covered with the heat insulating material, and does not block the moisture, so that the above-mentioned problems remain largely.
The prior art shown in Patent Document 2 is aimed at exterminating fleas and insect larvae and adults, and how to apply it to ant control in building foundation work is not assumed at all.
It was experimentally confirmed that the substance obtained from DOT powder, salt and water also had the same termite extermination effect as the 100% pure DOT crystal.

The fundamental problem is how to prevent the flooring and foundations from being exposed to the growth and condensation of decay fungi due to humidity, the progress of corrosion, and the constant preparation of the best habitat for termites. It is the establishment of a method that effectively combines strong termite-proofing and waterproofing without the use of volatile pesticides that cause serious health hazards. The method will be described below.
i-Instead of the conventional method of infiltrating the foundation concrete with termiticide, when the formwork of the foundation is removed (formwork removal), the surface of the foundation is waterproofed with a non-breathable waterproof material (agent). Install (waterproof construction).
Prepare ii-DOT powder: salt: water ≒ weight ratio 1: 1: 1 (preparation stage for crystal formation).
Thoroughly mix iii-DOT powder and salt (first stage of crystal formation).
Add water little by little to iv-iii. Crystallization begins immediately (second stage of crystal formation).
v- Apply a little more water to the surface of the waterproof material constructed with i with a flat brush so as not to be overtaken by the speed of crystallization (ant-proof construction).
vi-Soon, the surface of the waterproofing material will be covered with crystals, but these crystals are not decomposed or volatile (combination of waterproofing and anti-termite construction).
Thus, termites approaching here come into contact with crystals containing DOT and are surely exterminated, and at the same time, moisture that is generated from the foundation and travels along the wall to promote corrosion of the house and establish a perfect habitat for termites. The extermination effect lasts semi-permanently as long as it is completely blocked by a waterproof material, there is no concern about serious chemical contamination of the living space due to termite prevention construction, and the house is not collapsed or washed away due to a natural disaster.
This is a method for exterminating termites using the crystallization of disodium octaborate tetrahydrate powder, which is characterized by the above.

Since ant-proof construction is performed using crystals made from DOT powder that is not decomposed or volatile, unlike conventional ant-proof construction, chemical substances that are harmful to the human body continue to invade the living space and continue to drift, which is disastrous. There is no need to worry about developing sick building syndrome. In addition, since the waterproof construction of the foundation can be completed without any contradiction with the anti-termite effect, the supply of moisture from the foundation to the inside of the wall can be cut off, and the establishment of the termite habitat can be fundamentally prevented.
As a result, it is possible to use ordinary heat insulating materials that have not been treated with anti-termite treatment on the floors and walls of houses, which leads to a large cost reduction.
Above all, the health of the people who live there will be protected, and the life of the house will be greatly extended.

Hereinafter, embodiments of the present invention will be described with reference to FIG.
The basic construction process of the present invention is (1) waterproofing (2) and anti-termite construction (6) that start when the work is completed. Before the stage of removing the mold (1), prepare a non-breathable waterproof material (agent) to be used for waterproofing (2). Immediately after the work of removing the mold (1) is completed, waterproof construction (2) is performed on the surface of the foundation concrete using the prepared non-breathable waterproof material (agent).
After that, the ant-proof construction (6) process is started.
First, a crystal preparation preparation stage (3) in which DOT powder, salt and water are prepared in a weight ratio of 1: 1: 1. Next, the first step of making crystals by thoroughly mixing DOT powder and salt (4). Water is added little by little into this mixture, and at the same time, the crystallization phenomenon begins immediately in the second stage of crystal formation (5). In that case, to avoid being overtaken by the speed of crystallization, while adding a generous amount of water, hold a flat brush and quickly apply it to the surface of the waterproof material that has already been completed. (6). The surface of the applied waterproof material will soon be covered with crystals, and the combination of waterproof construction and anti-termite construction (7) will be realized. When the termite's body touches the resulting crystals, the seriali is instantly killed by the powerful toxic active ingredient of DOT.
When making a mixture using DOT powder here, the amount of water is greatly related to the temperature and humidity of the day, so it is desirable to adjust while adding water and use the ratio of water in the mixture as a basic guideline. In particular, the vertical surface of the foundation wall needs to be carefully adjusted with water. Although the mixed weight ratio of DOT powder: salt: water is basically 1: 1: 1, crystals can be formed even with slight changes, but the time difference in the extermination effect varies depending on the amount of salt. You should know that it will happen.
