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 spiral repellent is an innovative and effective product designed to keep mosquitoes at bay. This unique item takes the form of a spiral coil that is carefully crafted to provide reliable protection.

The mosquito spiral repellent works by releasing a specific blend of substances that are unpleasant or deterrent to mosquitoes. When lit, the coil begins to slowly burn, emitting a gentle smoke that spreads through the air. This smoke creates a sort of barrier that mosquitoes find difficult to penetrate, effectively reducing their presence in the area.

One of the great advantages of the mosquito spiral repellent is its ease of use. It can be simply placed in a suitable holder and ignited, and it will start working immediately. It is suitable for use in various settings such as homes, gardens, porches, and even while camping.

The spiral design of the repellent ensures a consistent and long-lasting effect. It allows for a controlled release of the active ingredients over time, providing continuous protection. The duration of its effectiveness can vary depending on factors such as the environment and the quality of the product.

In addition to its mosquito-repelling capabilities, some mosquito spiral repellents may also have a pleasant fragrance, which can enhance the overall experience. However, it's important to ensure proper ventilation to avoid excessive smoke build-up.

Whether you're enjoying a peaceful evening outdoors or trying to get a good night's sleep without being disturbed by mosquitoes, the mosquito spiral repellent is a valuable tool. It offers a practical and relatively inexpensive way to create a mosquito-free zone and enjoy your time without the annoyance of these pesky insects.
