The production process and raw materials of mosquito-repellent incense have always been a concern. The traditional method of making mosquito coils is really troublesome and requires specific materials. First of all, the original mosquito coil appeared in the Song Dynasty, and its production raw material is mainly realgar, which is a kind of arsenic sulfide ore, which has a strong insecticidal effect. Duckweed collected during the Dragon Boat Festival is dried in the sun and mixed with realgar to make paper rolls to burn, which can effectively repel mosquitoes.

In modern times, the production methods and raw materials of mosquito coils have changed. Modern mosquito coils are usually made by mixing wood flour and starch, then adding spices and colorants. This method is simple and quick, and different spices can be added as needed to achieve the purpose of mosquito repellent and fragrance.

However, there are also methods of making mosquito coils by hand, which are more natural and pollution-free. Only wormwood powder and Xiangnan powder (the natural adhesive of nanmu bark) can be made into natural non-polluting mosquito coils. This method is troublesome, but it is more reassuring to use.

In general, the raw materials and processes of mosquito coils change with the times. From traditional realgar and duckweed, to modern wood flour, starch, spices and colorants, to handmade wormwood powder and vanilla powder, each method has its own characteristics and advantages.

Mosquito repellent coil is a popular and practical product for warding off mosquitoes. It is designed in a coiled shape, which is both unique and functional.

This mosquito repellent coil contains special ingredients that have a strong repelling effect on mosquitoes. When it is lit, it starts to burn slowly and continuously release a certain smell that mosquitoes dislike. The smoke produced spreads in the air, creating a zone where mosquitoes are reluctant to approach.

The great thing about the mosquito repellent coil is its ease of use. You can simply place it on a stable surface or in a dedicated holder. It provides relatively long-lasting protection, allowing you to enjoy a mosquito-free environment for a period of time.

It is suitable for various occasions, such as outdoor activities like camping and picnicking, as well as indoor spaces like rooms and porches. It offers a convenient and cost-effective way to deal with mosquito problems.

Moreover, some mosquito repellent coils may also come with additional features like a pleasant fragrance to make the experience more enjoyable. However, it's important to ensure proper ventilation when using it to avoid excessive smoke build-up.

In conclusion, the mosquito repellent coil is a reliable and accessible solution for those who want to keep mosquitoes at bay. It provides an effective means of protecting yourself and your family from the annoyance and potential harm caused by mosquitoes. Whether you're in the garden or at home, it can help create a more comfortable and mosquito-free space.
