2. Grasp the application opportunity. The colony of Reticulitermes flavipectus often appears in rainy days in February and March, when the weather suddenly turns fine, the temperature rises rapidly to above 20 degrees (the first temperature rise in early spring), and the air pressure drops to 10 134Pa, generally at 106 1 Pa. In an area, it is generally divided into 2~4 groups a year, and it is better to apply the medicine after the first group 10 day to the last group, and the effect of applying the medicine on the same day is the best.
3. Choose the best place to apply.
4, daub should be deep, uniform and scattered.
5. Review the following year and apply continuously. Because there are many termite groups in a certain area, some of them have no grouped holes and signs of harm in that year, so they are easy to be left behind when applying pesticides.
Third, control termites piled in the sand.
Sand-piling termites belong to the family Termitotidae, belonging to the family Termitotidae. There are 9 species in China, distributed to the south of latitude 28. It has been found in Taiwan Province, Fujian, Zhejiang, Guangdong, Guangxi, Yunnan, Guizhou and Sichuan in China. The main hazards of sand termites are internal wooden components and wild trees and fruit trees. The found parasitic plants are litchi, coconut, banyan, maple, ruojun and Lagerstroemia indica.
Four, termite control, control points
1. fumigation: this is an important method to control sand termites. Fumigating agents must undergo special technical training. Staff should wear gas masks. For wooden furniture corroded by sand termites, small ones can be fumigated in fumigation room or fumigation box. The doors and windows of the fumigation room must be sealed with kraft paper, and the fumigated articles can also be covered with plastic film, and sand should be pressed around to prevent air leakage.
2. High-temperature termite control method: Termites piling sand will die in a few hours at a high temperature above 60 degrees. Therefore, using various methods to generate high temperature and treat rotten wood can prevent and control this kind of termites. Furniture corroded by sand termites can effectively kill termites if it is treated at 65℃ for 65,438+0 hours and 30 minutes or at 60℃ for 4 hours.
3. Soil treatment method: Because termites mostly penetrate the soil and enter the house. Therefore, it is necessary to treat the soil and establish toxic soil areas.
4. Wood treatment method: Wood parts of houses, such as beams, columns or slabs, which are in direct or indirect contact with the underground, must be treated.
5. Cleaning and treatment method: In the place where termites have corroded, holes can be drilled and termites can be injected for mass killing. Other places, such as wood surfaces, soil and building foundations, must be thoroughly treated.
