Because mosquito coils have entered thousands of households, they can help us to repel mosquitoes very well. However, we have found that there are many types of mosquito coils sold on the market. So many people don’t know which one they should choose, or which mosquito coil is non-toxic and harmless. So now let us specifically understand and learn about the hazards of smokeless mosquito coils. In fact, the active ingredients of most mosquito coils are pyrethroid insecticides, as well as organic fillers, adhesives, dyes and other additives. Therefore, the smoke from burning mosquito coils contains many substances that are harmful to the human body and may induce diseases such as asthma. It is estimated that the amount of particles released by lighting a roll of mosquito coils is roughly the same as the amount of particles released by burning about 100 cigarettes. The ultrafine particles released can enter and remain in the lungs, which may cause asthma in the short term and cancer in the long term. Secondly, there are carcinogens produced by incomplete combustion of the mosquito coil base material, as well as some compounds that irritate the upper respiratory tract, which can poison the human nervous system. It is best to use safe and natural methods to repel mosquitoes in summer, such as using mosquito nets or screens to keep mosquitoes out; or placing a few opened boxes of cooling oil and wind oil in the bedroom. Of course, if you want to eliminate mosquitoes at the source, it is best to clean up places where mosquitoes can easily breed and reproduce, especially standing water and blocked sinks.

The mixture is put into a tubular mold and squeezed into thin strips in the same shape as incense. After shearing and air-drying, it becomes incense. Although mosquito coils are easily accessible in our daily lives, we all need to pay attention to their correct use and how to make scientific choices. We must also abide by the principles of using these mosquito coils so that we can better reduce some hazards, help ourselves maintain health and prevent the occurrence of diseases. |
