Founded in 1994 and located in Zhangshu, Jiangxi, Shanfeng Daily Chemical Co., Ltd. has a history of producing mosquito coils for more than 20 years, and is the vice chairman unit of the China Family Health Insecticidal Products Committee, and participates in the formulation of national standards for sanitary insecticides.
 
At present, there are three main products of mountain mosquito coils, all of which are incense mosquito coils. Among them, the herbaceous strong mosquito coil has a herbaceous fragrance, and the content of 0.08% of the permethrin is the active ingredient for mosquito prevention, and the anti-mosquito effect of this concentration is very strong, and the packaging is 50 trays plus trays, which can burn for 12 hours, which is consistent with the long-term time of Golden Bird and Ansu. The disadvantage is that this mosquito coil is a smoked type, and the amount of smoke produced is slightly more, which may choke the nose when using it while sleeping, affecting the quality of sleep.
 
The active ingredient of Doll Le smokeless mosquito coil is tetrafluoromethrin, with a content of 0.03%, the performance is decent, and the price of 30 trays is 12 yuan, which is also a choice for consumers who have no special requirements.
