The trademark of Golden Bird was registered in 1910, but its history can be traced back to 1885, pyrethrum is one of the world's three major insecticidal plants, affected by the First World War, the origin of pyrethrum Yugoslavia was severely hit, and after the war a new cultivation center was transferred to Japan. During this period, Golden Bird developed the world's first spiral disc mosquito coil and electric mosquito coil liquid.
 
Golden Bird started with pyrethrum business, but the natural ingredients of pyrethrum are photosensitive, easy to be oxidized by the air and cause the active ingredients to fail, so Golden Bird has gradually adopted synthetic pyrethroids in the development process, making the product more in line with people's needs. Goldbird's existing electric mosquito coil liquid uses a relatively rare flumethrin formula. Trimethoprim fluthrin is a new generation of products developed by Sumitomo Corporation of Japan, its vapor pressure is 1.96×10-3Pa, 25 °C, which is 2 times that of d-allethrin, good volatility, strong insecticidal activity, under experimental conditions, the knockdown effect on Culex mosquitoes and Aedes mosquitoes is 60 times that of d-almethrin, a common mosquito coil component.
 
As the founder of mosquito coil products, in addition to the high effectiveness of the formula, its electric mosquito coil liquid is also better than common brands in solvent, and uses safer water-based solvents. Electric mosquito coil liquid usually uses deodorized kerosene (purer n-tetradetane, which is an organic solvent) as the solvent, which has a flammable risk, while water-based solvents do not have this problem and are healthier for people. The use time of the Golden Bird is very long, 45ml liquid medicine is divided into 720 hours and 1080 hours, the price is 90 yuan for two bottles and 130 yuan for two bottles, respectively, which is more expensive than similar Chinese brand products.
 
However, the Golden Bird Electric Mosquito Recoil does not have a "60 times" killing effect in practical applications. The national standard GB/T 13917.10-2009 simulated on-site efficacy of electric mosquito coil liquid is based on the evaluation of the mosquito knockdown rate within one hour, and the mosquito cannot be knocked down in a short time in the actual environment. Mosquito coil products are used to defend against mosquitoes by contact, mosquitoes will not actively avoid mosquito coils, and the immediate mosquito prevention ability is poor, on the other hand, affected by external factors such as air flow, the actual effect is different.
 
Mosquito repellent is the most commonly used anti-mosquito product in East Asia, although its anti-mosquito effect is not as good as mosquito repellent water and mosquito nets, it is still a reliable anti-mosquito means, easy to use, and affordable. Electric mosquito coils overcome the shortcomings of traditional mosquito coils, such as open flame hazards and choking smells, and are more in line with the needs of modern people. Use electric mosquito repellent in a space of 15~20 square meters, knock down mosquitoes, close the screen window or plug the room gap in time to prevent mosquitoes from entering, and give full play to the anti-mosquito effect. If the air convection in the room is fast, the mosquito repellent liquid volatilizes and disperses evenly, which can also better play the anti-mosquito effect.
 
It is a pity that although Golden Bird Electric Mosquito Repellent has great advantages in products, it has not entered the Chinese market at present, and it is inconvenient to buy, so it needs to be purchased through overseas shopping or purchasing channels.
