What are the principles of mosquito coils killing mosquitoes?

In summer, when the weather gets hot, mosquitoes begin to reproduce continuously, and there will be more and more mosquitoes. At this time, if people are outdoors or sleeping at home, they will often be bitten by mosquitoes. Usually we choose to use mosquito repellent methods such as mosquito coils to repel mosquitoes. So what are the principles of mosquito coils killing mosquitoes? Next, let’s take a closer look at the main ingredients of mosquito coils and the principles of mosquito repellent.

The active ingredient in modern mosquito coils is pyrethroids, which have the effect of repelling and killing mosquitoes. Mosquito coils are the oldest natural way to repel mosquitoes. As early as the Southern Song Dynasty, mosquito repellent incense sticks made of traditional Chinese medicine appeared. The active ingredient in modern mosquito coils is pyrethroids, which have the effect of repelling and killing mosquitoes. After the mosquito coil is lit, the pyrethrin in the coil evaporates with the smoke and spreads in the indoor air, paralyzing the mosquito's nerves, so that the mosquitoes either fall to the ground and die, or flee in all directions, thus achieving the effect of repelling mosquitoes.

Pyrethrins can be excreted from the body through metabolism and are not very harmful to humans. However, some inferior mosquito coils, in addition to pyrethrins, also contain hexachlorocyclohexane powder, realgar powder, etc. These substances are toxic and even carcinogenic to the human body. Therefore, it is best to use mosquito coils outdoors, such as around the home, at the door or in places with good air circulation. Lighting mosquito coils before dark in the evening will have the best effect in repelling mosquitoes.

Electric mosquito coils also have a good mosquito repellent effect, which can generally last for 6-8 hours. The principle of repelling mosquitoes by electric mosquito coils is to absorb pyrethrum and other insects into the mosquito coils, which evaporate after heating. If a few drops of medicated oil are added, the effect will be better.

Liquid electric mosquito coils use the capillary principle to continuously heat and release insecticide substances, making them the most convenient to use. Assuming eight hours of use per day, a bottle of mosquito coil liquid can be used continuously for 30 days, eliminating the trouble of replacing electric mosquito coils every day. But whether it is electric mosquito coils or liquid electric mosquito coils, they contain organic compounds that are harmful to the human body. If used in a closed room, adverse reactions may occur. Therefore, air circulation should be maintained when using electric mosquito coils. The best time to use electric mosquito coils is half an hour before going to bed.

Through the above detailed introduction to the principles and main ingredients of mosquito coils in killing mosquitoes, those who often use mosquito coils to kill mosquitoes in summer will have a better understanding of the principles of various common mosquito coils or mosquito coils on the market. When we buy mosquito coils, we must carefully look at the main ingredients of the mosquito coils and buy them in regular stores to avoid buying inferior products.
