Why mosquito-repellent incense can kill mosquitoes?

Mosquito coils can kill mosquitoes. At present, most mosquito-repellent incense on the market contains pyrethroid insecticides.

There are not many categories of mosquito-repellent incense in the market. At present, the first organophosphorus, trichlorfon and natural enemies of pests are ranked according to toxicity. The second is carbamate, propoxur and methomyl. The third kind of pyrethroids, including cypermethrin and fenpropathrin, allethrin and ES biological pyrethroids, are also important. Liquid mosquito-repellent incense is better than electric mosquito-repellent incense, and electric mosquito-repellent incense is stronger than burning coil incense.

Long-lasting mosquito-repellent incense is the earliest pesticide used. Thousands of years ago, similar mosquito repellent sticks made of traditional Chinese medicine appeared in the Southern Song Dynasty. Mosquito-repellent incense burns at high temperature, so that pesticides are slowly released into the air, and the mosquito repellent effect is greater than that of mosquito killer. Experts suggest that mosquito-repellent incense should be used outdoors, such as around houses, at doorways or in well-ventilated places.

Lighting the mosquito repellent lamp before dark at night has the best mosquito repellent effect. Based on the capillary principle, the liquid electric mosquito-repellent incense tube that continuously releases pesticides can make up for the shortage of electric mosquito-repellent incense tube. Liquid electric mosquito-repellent incense can be used continuously for about 60 days for a long time, and can even be released regularly. According to the report of the Institute of Health, there are many unknown harmful compounds besides chemicals such as Lenin and toluene.

If used in a closed room, serious allergic reactions may occur, such as sore throat, stuffy nose and headache. Therefore, when using electric mosquito coils, it is recommended to keep the air circulating. Half an hour before going to bed is a good time to use electric mosquito coils. When in use, people and pets must leave with the doors and windows closed.
