Background Mosquitoes and flies are important media for transmitting dozens of diseases such as malaria, dengue fever, cholera and the like, and form serious threat to human health. The traditional mosquito and fly prevention technology has the following systematic defects: Common chemical control methods such as spray and mosquito-repellent incense can release formaldehyde, benzene series, pyrethroid and other chemical substances, and long-term use of the chemical control methods can easily cause human health damage, such as respiratory diseases, nervous system influence and pest resistance induction. In addition, physical prevention and control methods such as fly-sticking paper and electric mosquito swatters have no chemical pollution, but the insect bodies are manually cleaned, the process is unhygienic and bacteria are easy to breed, and the products are mostly made of nondegradable plastic base materials and form white pollution after being abandoned. Meanwhile, the method has ecological and safety problems, chemical agent residues are enriched through food chains to threaten food safety, and the method has killing effect on non-target organisms (such as pollinating insects) to destroy ecological balance. More importantly, the existing products generally lack effective life indication, so that a user cannot intuitively judge the replacement time, and prevention and control failure or resource waste are easy to cause. Therefore, a next generation mosquito and fly control product which can realize high-efficiency killing synchronously, is safe to use, has visible state and is environment-friendly is needed in the market. The ideal product has the capabilities of targeted trapping, rapid harmless treatment of insect corpses, intelligent prompt replacement and complete degradation and natural return after use.
