Why mosquito coils and other items can achieve the effect of repelling mosquitoes

Mosquito coils repel mosquitoes, the main ingredient is mosquito repellent vanilla, which contains the chemical component of pyrethroid resin, and mosquitoes will run away or fall unconscious when they encounter this smell. Mosquito coils are a mosquito repellent that emitted smoke when lit to drive away 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 soot, polycyclic aromatic hydrocarbons, carbonyl compounds 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.

The composition of mosquito coils is different, and the harmful gases produced in the burning smoke are also different, among which ultrafine particles are the most common. Some low-quality mosquito coils also produce polycyclic aromatic hydrocarbons, carbonyl compounds and benzene when burned, all of which are toxic gases.

Huang Chaowan, a mosquito repellent product engineer, said that the difference between tasted and tasteless is whether there is any flavor, the active ingredient is the same, in fact, the fragrance is the same as the perfume people useAlthough it is divided into incense and no incense, the mosquito killing effect is still good for mosquito coils, but the smoke of mosquito coils is also killing people at the same time, I don't know if you have noticed, since you lit mosquito coils, mosquitoes are gone, but your throat is itchy and uncomfortable, and you begin to cough dryly. That's what you're inhaling from mosquito coils.

The principle of action of mosquito coil liquid and mosquito coil tablets is the same, they are smoked by smell, as long as their taste is not harmful to the human body, mosquito coil liquid is more convenient, some mosquito coil tablets have to be changed every day, these two are still mosquito coil liquid is better, in fact, both mosquito repellent effect is very good, but when it comes to safety, it is still good mosquito coil liquid, mosquito coil tablets sometimes accidentally cause a fire. Therefore, the effect is as good, and you should choose a safe product.

The use time of a plate of mosquito coils is shorter, for example, a plate of sandalwood-type incense sticks of Olive Chrysanthemum can be burned for about 5 hours, while a bottle of mosquito coil liquid such as Olive Chrysanthemum Electric Mosquito Coils can be used for about 50 nights. The mosquito repellent liquid is good, there is no smoke smell and smell, it is better than mosquito coils, mosquito coils have a smoke smell. Mosquito coils should be ordered quickly, and there will be no mosquitoes after a while after lighting the mosquito coils.

As long as the wrapping paper is opened, and then the lid is closed, it is hollowed out on the cover, mainly relying on the smell it emits to achieve the effect of mosquito repellent, and the mosquito repellent liquid needs to be energized and heated to let the smell in the mosquito repellent liquid come out for mosquito repellent. The electric mosquito coil liquid has no open smoke and flame, is safe and clean, has a good use effect, and the liquid mosquito coil can last for a long time, only need to switch on and off the power supply every day, no need to add or replace, and it is easy to use. Therefore, if you use it all night and there is a lot of space, it is recommended to use an electric mosquito repellent solution.

The harm of mosquito coils is a little smaller, the general mosquito coils are made of Chinese herbal medicine, the strength of mosquito control is average, and the mosquito killer lamp is a combination of chemical drugs and mosquito coils, which is even worse.

Mosquito coil liquid is less harmful, mosquito coils need to be lit to repel mosquitoes, smoke contains substances and smoke that are harmful to the human body, such as organophosphorus, carbamates, long-term inhalation of these substances to the body is more harmful, so it is recommended to use mosquito coil liquid.

Mosquito coils are less harmful, and they will not emit a particularly strong smell, and they will not affect the respiratory system, and the effect of mosquito repellent is also relatively good.

Mosquito coils are to kill mosquitoes, and burning mosquito coils can kill a large number of mosquitoes. Therefore, mosquito coils are particularly powerful killers, specifically killing mosquitoes.

1. The main components in mosquito coils are pyrethroids, organophosphorus, carbamates, and the mosquito coils are burned to emit the smell of these substances, and when mosquitoes feel harmful or nasty to themselves, mosquitoes will not approach the range of these smells, so as to achieve the effect of mosquito repellent.

2. However, with the evolution of mosquitoes, there will also be mosquitoes that are more tolerant to mosquitoes and unaffected, so in many cases, mosquitoes cannot be completely removed.

The most important ingredient in mosquito coils is pyrethrum.

It blooms white flowers in early summer. Before industrial mass production, the flower center part was made into powder and used as a raw material for insect control. Nowadays, more compounds with similar properties are used in the industry, called allethrin (allethrin), which can be distinguished by looking at the ingredient list, and many businesses are still selling whether they are natural or not.

Allethrin will vaporize at 250, and the smoke of mosquito coils actually helps to diffuse the active ingredients, so the mosquito coils are not actually smoke, but allethrin that is roasted to vaporize before smoking!
