The main food of termites is wood fiber, which can eat all plants while secreting formic acid in the body. In daily life, wood and wood products are indispensable articles for us. Termites, including paper and clothing made of wood, prefer to erode. Therefore, some collected newspapers, books and periodicals, even some cultural relics are often damaged by termites. In addition, plastic, rubber and other products are also damaged by termites, such as underground cables for communication or power supply, electrical appliances and the like. Therefore, the termites not only damage our furniture and houses, but also affect many departments such as telecommunication, cultural relics, factories, army national defense and the like. The termite-proof agent has a larger influence on agricultural, forestry, water conservancy and other departments, and some transportation departments such as steamships, trains, automobiles and the like also have termite damage, so that the termite damage is ubiquitous in daily life. The damage of the termites to the house buildings, particularly to the brick-wood structure and the wood structure buildings is serious. Because the house is hidden in a wood structure, bearing points of the house are damaged or destroyed, the house is often collapsed suddenly, and great attention of people is attracted. The severity of termite damage to river dikes has been recorded in more detail in ancient literature in China, and the recent records are more detailed. The method is characterized in that the method is used for densely nesting in a dam, rapid propagation is carried out, the field is distributed by adopting the star-and-go chess, ant paths are all-round, some ant paths even penetrate through the inner slope and the outer slope of the dam, when the water level rises in the flood season, the danger of pipe leakage often occurs, and the dam collapse and dam collapse are caused by the more violent ant paths.
For a long time, the method for preventing and controlling the termites is drug prevention, the adopted pesticide can cause environmental pollution and harm to human health when being applied to soil. Accordingly, there has been proposed no-drug prevention, and a termite control device has been devised in which a bait strip preferred by termites is placed as a bait in a housing having an opening, the device is taken out after a certain period of time to see whether the bait strip is corroded or not, and to determine whether termites exist or not, and since the device is installed every several meters in a building, the amount of work is very large.
