Method for killing dam termite and used smoke generating device

Abstract

A dam termite killing method and a smoke generating device thereof relate to a method for killing insects. The invention aims at providing a method of being capable of killing main termites in main termite caves of dams. The technical proposal of the invention is a dam termite killing method. Firstly, the entrances and exits of a termite cave are found out, and smoke without termite control drugs is blown in any entrance and exit of the termite cave; observing the surroundings, when the entrances and exits of the termite cave are smoked, a cave mouth is artificially plugged; the entrances and exits of the termite cave are plugged one by one by the method; when the smoke pressure inside a smoke feeding pipe is raised, smoke feeding is stopped; secondly, smoke with termite control drugs is blown in the entrances and exits of the termite cave for feeding smoke so that each plugged smoke exit is opened; when the entrances and exits of the termite cave are smoked, the smoke exit is plugged; after all smoke exits are smoked and plugged, smoke feeding in the termite cave is continued; after the pressure inside the smoke feeding pipe is raised and stabilized, the smoke feeding is stopped. The invention is used for dam termite killing.

Description

Technical field: [0001] The invention relates to a method for killing insects, in particular to a method for killing dam termites and a smoke generating device used therein. Background technique: [0002] The termites in the dams are very harmful to the safety of the dams due to their strong reproductive ability. In order to kill the termites in the dams, people have adopted various methods, such as biological methods, artificial methods, physical methods, etc., to kill the termites. The drug has long been available, and the killing effect is also very good. The reason why ant extermination is difficult is that it is difficult to determine the orientation of the main ant nest where the main ant is located. Only when the main ant nest is found and the main ant is killed can the fundamental problem be solved. Since the ant tunnels are three-dimensional curved in the embankment, and the distribution range is as large as tens of meters, it is very labor-intensive to find them b...

AI Technical Summary

Problems solved by technology

Because the ant tunnels are three-dimensional curved in the embankment, and the distribution range is as large as tens of meters, it is very labor-intensive to use manual excavation to find them, and it will cause damage to the embankment

Foreign countries use radar detection to find the main cave. Generally, the effect is better for the main cave within one meter. If the main cave is more than one meter or even reaches 2-3 meters, it cannot be detected. This kind of detection radar is expensive, and the cost of extermination too high

There is a method of killing by irrigation. Because the ant tunnel is curved and widely distributed, a large amount of medicine needs to be applied, but the medicine liquid can not be accurately tanked to the main cave. Due to the large amount of application, it is easy to cause the medicine to penetrate and pollute the water body.
