SC Johnson USA is a family-owned company with more than 100 years of history, mainly dealing in household cleaning products, personal care products and insecticide products. Rado is a series of sanitary pest control products of SC Johnson in the United States, with business in more than 100 countries, high brand recognition, and a market share of more than 13% in China's sanitary insecticide products. Radar electric mosquito coils have the largest market share in the Chinese market, reaching more than 20% in 2016, and are widely distributed in supermarkets and e-commerce platforms, making them easy to buy.
 
Mosquito coils can be said to be one of the first hygienic insecticide forms used to prevent mosquito bites, and people have developed electric mosquito coils by applying PTC materials that can stabilize heat generation to heaters. Compared with traditional mosquito coils, electric mosquito coils have the advantages of smokeless, no ignition, and safe use, and are gradually replacing mosquito coils.
 
Although electric mosquito coils are an advanced product of mosquito coils, the mosquito killing ingredient is still pyrethroids, and the insecticidal principle is the same. Radar electric mosquito coil liquid mainly uses tetrafluoromethrin or chlorofethhrin, due to the dosage form, mosquito coil liquid single product only has one insecticidal ingredient, can not be compounded, mosquito coil tablets can be compounded with a variety of ingredients.
 
Tetrafluoromethrin is an pyrethroid drug developed by Sumitomo in Japan in 2001, which is more effective than the popular drugs such as promethrin in the 70s, and has promoted the innovation of pyrethroid insecticides in the Chinese market. The radar electric mosquito coil is mainly formulated with 0.62% tetrafluoromemethrin, and the dosage of the children's product Jia'er Care is halved, which is promoted to be safer for children. However, such mosquito killing products need to be approved by the pesticide management department, and the safety of pyrethroids is also fully verified, and the content of ingredients in the civil mosquito coil liquid is usually treated with a low dose to achieve the effect of knocking down mosquitoes, which is safe for the human body under normal use, and is also for children, and there is no need to deliberately use low doses. Lowering the dose may also result in a decrease in mosquito killing effectiveness, which is more to imply that the product is safer and promote consumption.
 
In actual use, we may often use electric mosquito coils all night, and forget to turn them off after getting up, which is easy to waste the medicine. The radar mosquito coil is also available in a smart version, with a timer and switch function, which can not only preset the use time, but also adjust the heating level, and turn it off without plugging and unplugging. The smart model is not much more expensive than the ordinary model, and its smart heater is priced at 25 yuan for 68 nights, which is more convenient to use.
