Why mosquito-repellent incense can kill mosquitoes? What principle?
Principle: Mosquito-repellent incense has a long history and is the earliest pesticide used. Similar mosquito repellent sticks made of traditional Chinese medicine appeared in the Southern Song Dynasty thousands of years ago. Mosquito repellent incense slowly releases pesticides into the air by burning at high temperature, and its mosquito repellent effect is greater than that of mosquito killer.
Disadvantages: A study also found that mosquito-repellent incense synthesized from sawdust and rice bran will produce a substance after being ignited and oxidized, which may cause cancer.
Suggestion: Experts suggest that mosquito-repellent incense is best used outdoors, such as around the home, at the door or in a well-ventilated area. Lighting mosquito-repellent incense at night and before dark is the best way to repel mosquitoes.
Electronic mosquito repellent principle: Mosquitoes are repelled by burning insecticidal substances such as tianduowei and DDT and emitting insecticidal substances.
