Hebei Kangda Co., Ltd. is the largest insecticidal aerosol manufacturer north of the Yangtze River, and is also one of the northern health insecticide research and production bases.
 
The Gunner Electric Mosquito Recoil is all formulated with 0.9% chlorfluthrin, which is divided into three types: odorless, lavender, and fragranced. Gunner's odorless electric mosquito coil liquid sells the best, the smell of mosquito coil is not obvious when used, and its predecessor product uses 1.24% tetrafluoromemethrin, which now uses a unified formula, and the mosquito killing effect is almost the same.
 
Although the operation of the electric mosquito repellent is simple, the actual efficacy has a great correlation with the correct way of use. Gunner's electric mosquito repellent products kill mosquitoes by volatilizing liquid, and the effect is better in a relatively closed space of 15~20 square meters, and the effect is poor in larger spaces such as living rooms. Use electric mosquito coil 1~2 hours before going to bed, and close the screen window to prevent external mosquitoes from entering, which can kill indoor mosquitoes, and there is no need to turn on the electric mosquito coil all night. In a ventilated and open environment, it is difficult for electric mosquito repellent to defend against mosquitoes all the time, and people will inevitably be bitten.
