The problem of mosquito coils, how to improve the shortcomings of mosquito coils

You must know that ordinary mosquito coils (lit mosquito coils) are non-toxic in themselves, and they are not poisonous until they are packaged and sprayed with mosquito coils (poisonous).

And the electric mosquito coil liquid is also a mosquito coil medicine, I think, its harm is not less than ordinary mosquito coils!

Because, I myself make mosquito coils!

Therefore, I personally think that the ignition mosquito coil is less harmful!

I think that electric mosquito coils are less harmful to the human body, and buying a mosquito net is a good idea.

I think it's better to buy a mosquito net, which is not harmful to the human body.

Hello dear, happy to answer your <>

Answer: The disadvantages of mosquito coils are improved in this way: 1

The insecticide formula of mosquito coil can be adjusted at will, mosquitoes are not easy to adapt, and the mosquito repellent effect is good; 2.The first insecticide form is evenly distributed on the mosquito coil strip, and the insecticide is evenly dispersed by gradual heating, and the mosquito repellent effect is stable; 3.No power supply required; 4.

**Cheaper disadvantage 1, the gas smell released is obvious 2, you need to keep the room extremely ventilated, if you don't ventilate, it is easy to cause respiratory tract infections 3, mosquito coils are heated, and a certain amount of poison will be released when burning so please pay attention to keep the room extremely ventilated when using it!

In general, mosquito coils can repel mosquitoes or smoke them. Mosquito coils in China have a very long history, and the traditional mosquito coils are divided into two types: incense sticks and incense.

The smoke burned by mosquito coils contains four types of substances that are harmful to the human body, namely ultrafine particles - soot (particulate matter with a diameter of less than microns), polycyclic aromatic hydrocarbons (PAHs), carbonyl compounds (such as formaldehyde and acetaldehyde) and benzene. At the same time, in addition to these four obvious harmful substances, there are also a large number of organic fillers, adhesives, dyes and other additives in mosquito coils, so that mosquito coils can be smoldered without flames.

Ancient primitive mosquito coil origins.

The invention of mosquito coils may be related to the hygiene customs of the Dragon Boat Festival and the customs of burning incense and sacrificing incense in ancient times. "Jing Chu Years Chronicles" recorded: "The four people of the Dragon Boat Festival stepped on a hundred grasses, picked wormwood as people, hung on the household, and poisoned gas."

In the early years of the Dragon Boat Festival, in addition to inserting wormwood at the door, people often soaked realgar wine and applied it to their bodies. Doing so may make the air a little fresher and, secondly, prevent mosquito bites.

The invention of mosquito coils may also be related to the ancient custom of burning incense for sacrifices. China has long begun the custom of burning incense and sacrificing, and the earliest record of this custom is "Poems, Zhou Song, Weiqing": "Weiqing Jixi, the canon of King Wen, Zhaoyu."

It means that the Zhou people sacrificed to the sky by burning some firewood and smoked, which was called "禋" or "禋祀".

Stun the mosquitoes.

But if the mosquito coil is used more often and for a long time, the mosquito will have no effect.

The effect of mosquito coils on mosquitoes is to drive away stuns.

Now the main ingredient of mosquito coil is pyrethroid, which is a low-toxicity insecticide, it will make mosquitoes very uncomfortable, run quickly if you can run, and stun if you can't run.

If there are children, the elderly, and pregnant women at home, it is best to use mosquito nets, although mosquito coils are low-toxicity, they are still toxic and not good for human health.

The following is an excerpt from the wiki:

Pyrethroids, which are found in the leaves, stems, and especially flowers of pyrethroids (a plant of the Asteraceae family), have a strong poisoning effect on insects. Collect the flowers of pyrethrum to dry, mix with sawdust, spices, etc. to make a fumigant, after ignition, pyrethroid can be emitted with the smoke, once the flying mosquito touches it, it will be poisoned, this fumigant is an excellent natural "mosquito coil".

Pyrethroids are new products of modern chemical insecticides. Its contents are similar to pyrethroid essence contained in pyrethrum, which has the function of killing mosquitoes, and its insecticidal components are divided into pyrethrin I and II. The former is the main ingredient of insecticide, while the latter can have the effect of fainting ordinary insects.

This type of natural insecticide can be obtained from the powder of pyrethrum flowers, but it was not used in large quantities in the early days due to the high cost of extracting pyrethrum, the scarcity of production, and its easy photolysis properties.

Pyrethroid has a wide insecticidal spectrum, can kill many sanitary and agricultural and forestry pests, and has no resistance, and has little toxicity to humans and other warm-blooded animals, and no residual poison pollutes the environment. Its disadvantage is that the stability of light is poor, and it is easy to decompose and fail when exposed to sunlight, so it is only suitable for indoor use for mosquitoes, flies, cockroaches and other sanitary pests, and is not suitable for spraying in the field as a pesticide.

1. Gently push the two ends of the center of the mosquito coil with your fingers to divide the pure mosquito coil into two pieces, and if it is written in the instructions that you can light one piece without separating, you do not need to separate it.

2. Light the mosquito coil and put it on the mosquito coil holder.

3. If the mosquito coil is accidentally broken, it can be sandwiched in the incense shelf groove for use.

4. Mosquito coils should be placed on the wind inlet side, which can have a good effect of repelling mosquitoes.

1. The main ingredient of mosquito coil is an insecticidal agent, including benzene, phenol and xylene. These substances have some toxicity. Once a person inhales an excessive amount of toxic substances, it can lead to serious diseases, such as disorder anemia and even leukemia.

2. At the same time, when the mosquito coil is burned, a certain amount of soot will be produced, and the incense ash contains a part of the plant ash, and will also contain a small amount of heavy metals such as lead and chromium. The dust of mosquito coils is also very bad for people's health.

The harm of mosquito coils is very great, there are some organic fillers, adhesives, dyes and other additives in mosquito coils, these things are harmful to the human body, will cause asthma and so on, especially some of the elements in it, for example, there are some organophosphorus and pyrethroids, of which organophosphorus is the most toxic, pyrethroid toxicity is the weakest, and it is slightly toxic, these are toxic substances, which are obviously harmful to human beings.

In summer, many people will use mosquito coils, because mosquito coils are very lethal to mosquitoes, as long as you use mosquito coils, you will not be bitten by mosquitoes when you sleep at night, but mosquito coils are actually very harmful to the human body.
