This invention relates to a termite control method that can prevent termites from entering through gaps between the ground beneath the floor of a building and the pile stones or foundations. In general, termites nest at a depth of about 30 cm below the soil surface, build ant trails in the soil, prefer poor ventilation, warm, humid, and dark places, and do not damage wood in damp conditions. , is a well-known place. In addition, in houses, the areas under the floors, especially bathrooms, kitchens, washrooms, toilets, areas with leaking rain, and under the eaves where rain falls are ideal for termites, and the wooden parts such as foundations and pillars in these areas are ideal for termites. becomes the food of The damage caused by these termites is so severe that if you do not notice that you are infested with termites, your house may even collapse. Even in less extreme cases, it is common for houses to be left in a state beyond repair due to direct attack on the foundation. Therefore, the conventional method for controlling termites in buildings is that, as mentioned above, the termites build an ant trail in the soil, invade through the pile stones and foundations under the floor, and feed on damp wood (foundations, pillars, etc.). The following two methods have been implemented, focusing on their habits. In other words, the control agent is applied to the soil under the bed, piles of stones,
There are two methods: by soaking, coating, and spraying into the foundations and wooden foundations such as pillars (hereinafter referred to as "soil treatment method"), and by pouring concrete under the floor to achieve a moisture-proofing effect ( (Hereinafter, it will be abbreviated as the concrete pouring method). In the above-mentioned soil treatment method, over time, the control agent in the soil may be washed away by rain or the like, or the agent may lose its effectiveness due to deterioration over time. This, combined with the fact that gaps tend to form where the piles of stones under the floor or the foundation contact the ground, allow termites to pass through after a certain period of time. Furthermore, since it is impossible to prevent the wooden parts under the floors of buildings from getting damp, there is a risk that they will be damaged by termites after a certain period of time. on the other hand,
Although the concrete pouring method has a moisture-proofing effect compared to bare soil, it is not as effective as expected, and the concrete itself either cracks or is eaten by termites, so it is not perfect for termite control. do not have. This invention was made in view of the above circumstances,
The purpose is to provide a termite control treatment method that can maintain a sufficient termite control effect even after a long period of time. It is designed to fill the gaps where the stones and foundations contact the ground. This invention will be explained in detail below. The termite-proofing bituminous mixture used in the termite-controlling treatment method of the present invention is prepared by selecting one or more of the following insecticidal and repellent chemicals and adding 0.001 to 2% by weight of the same to the bituminous mixture shown below. It is added and mixed with the above bitumen mixture. ``Bitumen mixture'' A bituminous mixture that has particularly good pourability among heated asphalt mixtures, asphalt emulsion mixtures mixed at room temperature, and cutback asphalt mixtures used for paving general roads and premises. "Insecticides and repellents" Organochlorine, organophosphorus, carbamate, organotin, boron, chlorphenol, arsenic, chlornaphthalene, dichlorobenzene,
Organic fluorine-based, yellow phosphorus-based, tobacco-based, pyrethrum-based,
Derris-based insecticide and insect repellent. The amount of the above-mentioned insecticidal/insect repellent agent to be added is appropriately determined within the above range depending on its effectiveness and economical efficiency. Moreover, the above-mentioned amount added is indicated by the amount of the active ingredient of the drug. The drug may be mixed with the active drug ingredient alone, or may be prepared in the form of an oil, emulsion, or powder with appropriate diluents, solvents, emulsifiers, fillers, etc. Next, regarding the method of mixing the above-mentioned agent into an asphalt mixture, for example, a method of adding it to a fastening material such as heated and melted asphalt and adding it to the aggregate, or a method of adding it to the aggregate, or a method of adding it to the asphalt mixture at room temperature to improve long-term storage stability and workability. For this purpose, a light component oil is used, and the above-mentioned chemicals are added to this light component oil and sprayed onto the asphalt mixture at room temperature.Alternatively, an emulsion-type drug is added directly to the asphalt emulsion and this asphalt emulsion is used. Alternatively, a powder agent is added to the filler in the aggregate.In addition, an oil agent or a powder formulation is separately added to a long-term shelf-stable room-temperature mixture that has already been manufactured and stored, and then mixed and coated using a mixing device. Secondary processing such as this is also possible. Another method is to spray and mix the chemical over the general asphalt mixture spread on the site. Then, the steps of the pest control treatment method are to excavate a predetermined area and depth of the pile stones and foundation under the floor of the building, clean the area around the pile stones and foundation, and then pour the termite-proofing bituminous mixture. be done. EXAMPLES Hereinafter, the present invention will be specifically explained with reference to Examples. Example 1 Composition 60-80 straight asphalt 16.7% Chlordane 0.3% Limestone powder 28.0% Sand 55.0% The above composition was excavated in the soil around the pile stones and cloth foundations under the floor of a general house in a trench 15 cm wide and 30 cm deep. Pour the termite-proof asphalt mastic manufactured in After that, the following room-temperature termite-proofing mixture was applied to the entire surface of the subfloor to a thickness of 3 cm.
There were no gaps at the interface between the pile stones and the foundation and the termite-proofing asphalt mastic, and the adhesion became strong. Furthermore, no form of termite invasion such as construction of termite trails was observed over a long period of time. "Room-temperature mixture for termite prevention" Mixed aggregate shown in the table below is heated to 110℃, and cutback asphalt heated to 70℃ is added to this mixed aggregate.
Add 5.7% of MC800 and mix, then patent No. 598311
A room-temperature mixture for termite prevention that can be stored for a long time and manufactured by spraying 0.6% of the light component oil used in No. 1 with 2% chlordane mixed into the above mixture.

[Table] Example 2 The same termite-proofing asphalt mastic as in Example 1 was poured onto the pile stones under the floor and around the foundation, and then the chlordane emulsion was diluted with water so that the main component, chlordane, had a concentration of 2%. When I sprayed it on the entire surface under the floor at a rate of 5 parts per square meter, I was not harmed by termites for a long period of time (3 years). There were also cases where large numbers of dead termites were found around the pile stones and foundations. As can be seen from the above results, the termite control treatment according to the present invention has the effect of preventing termites from entering the lower part of the building floor, especially from the bundle stones and around the foundation, which are the route for termites, and killing termites. .
