Lanju was the first to open up the market with mosquito coils, and its smokeless mosquito coils occupy a large share of the mosquito coil market and are the most popular among consumers. Lanju is also the earliest manufacturer of electric mosquito coils in China, and at the same time participated in the drafting of national standards for household insecticide products. Its technology R&D center is known as the "mosquito bank" in the industry, and there are mosquitoes "purchased" from different regions to carry out targeted product development and testing.
 
Starting with mosquito coils, its product line has also been derived from household insecticides, and there are currently two products, namely quick-kill insecticides and children's health insecticides for children's families.
 
The main components of the quick-kill insecticide were 0.07% cypermethrin and 0.05% dextrotrans-chloropropylene, with a total content of 0.12%. Compared with the previous brand, the ingredients are more low-concentration potency, of which cypermethrin has a strong effect, the insecticidal spectrum includes flies, mosquitoes, cockroaches, bed bugs, ants, etc., mainly to contact killing, stomach toxicity, more use in agriculture, as a household insecticide ingredient, 0.04% content can achieve a lethal effect on pests, such content is less harmful to the human body, but it is still necessary to pay attention to avoid eyes, nose and mouth when using.
 
In addition, there is an alcohol-based Erbaojian insecticide, which uses food-grade alcohol as a solvent and sprays it without leaving a trace. A can of 600ML is priced at about 20 yuan, and the shelf life is 2 years, but many online shopping products are about to expire, and you need to ask customer service to determine the date when purchasing.
