Mountain Wutai Center of Disease Control and Prevention recently launched a campaign to eliminate the four pests (rats, bedbugs, flies and mosquitoes) in a bid to create a comfortable and health living environment.

Adhering to the "resolving the current problem and eliminating the root causes" principle, the campaign integrated environment, physics, and chemistry approaches such as painting and hanging drugs, residual spraying, and smoking. In addition, the center actively promoted garbage bags closed storage and strengthened storehouse and garbage management.
