Hygienic insecticides can be divided into three categories: chemical insecticides, biological insecticides, and insect growth regulators. Among them, chemical insecticides are the most frequently used, and the fastest-acting ones, and are the core of sanitation pest control.
The use of hygienic insecticides to kill various types of flying insects and reptiles is a major means. Hygienic insecticides work quickly, can control a variety of pests, are suitable for a wide range of applications, and have relatively low relative costs. They are powerful weapons for vector control.
Hygienic pesticides belong to a category of pesticides used for sanitary pest control, also known as public health pesticides. Different from agricultural pesticides that act to protect crops and kill agricultural pests, hygienic pesticides directly act on the living environment of human beings, some varieties (such as mosquito coils) even contact people for a long time. They are highly efficient, have low toxicity, and have less environmental pollution due to the protection of human beings. Therefore, hygienic pesticides have special requirements in terms of variety, purity, and impurities. In practical applications, agricultural pesticides cannot be replaced by hygienic pesticides because of their high efficiency and low price, especially now that people are paying more and more attention to the environment, and the impact of the use of pesticides on the environment is becoming more and more popular.
At present, to assess the pros and cons of a pesticide, whether it can be used as a hygienic pesticide, in addition to its high toxicity to sanitary pests and moderate price, the environmental impact should also be used as a measure of whether a drug can be used as a sanitary pesticide.
