Founded in 1982 and located in Zhongshan, Guangdong, Lanju Group is the earliest manufacturer of electric mosquito coils in China, and has now grown into the leader of China's household health and insecticide industry, and has participated in the formulation and revision of almost all national standards and industry standards in China's household insecticide industry, including household hygiene insecticidal products, household care and personal cleaning products. Its Lanju brand disc mosquito coil has always firmly occupied the first position in the domestic market, with many product lines and wide coverage, which is convenient to purchase in major supermarkets and e-commerce platforms.
 
At present, there are six main types of mosquito coil products on the market, which can be divided into two categories according to the active ingredients, one is the high-grade, wormwood and sandalwood mosquito coils containing 0.03% tetrafluoromethrin; The other category is smokeless mosquito coils containing 0.08% of chlorofethrin, wild chrysanthemum mosquito coils, and smokeless mosquito coils for pediatric health care with a content of 0.05%.
 
Tetraflumethrin was developed by Sumitomo in Japan in 2001, with high activity and high stability, and its efficacy is about 15 times that of allethrin under the same conditions, slightly lower than that of chlorfluthrin, with high safety and basically harmless to the human body.
 
In addition to the high-end and pediatric health smokeless mosquito coils for non-fragrant mosquito coils, the other kinds of mosquito coils are all fragrant mosquito coils, but the fragrance still comes from the added essence, and the overall strength is not as natural as Golden Bird and Ansu. In terms of smoke, Lanju does a good job, and it is inseparable from radar, these products are all smoke-free, and they all use the most advanced smoke-free technology so far, which reduces the impact on the indoor environment. The combustion time is also controlled at 8 hours, which is better than the 7 hours stipulated in the national standard.
 
Smokeless mosquito coils for pediatric health care claim to be mosquito coils for children, but in fact, the content of permethrin is reduced by 40% compared with other types to promote the application to children, but it is just a gimmick, and China does not divide mosquito coils into the elderly, children, and adults according to the population. The safety of pyrethroids has been fully verified, and they are safe for the human body under normal use, and there is no need to use low doses, which are too low to affect the effect of mosquito repellent. If you have children at home, you don't need to care about the active ingredients, but should choose smoke-free and fragrance-free types and electric mosquito coils as much as possible to reduce the irritation of smoke and fragrance to children's respiratory tract.
