V-mart photo-catalyst mosquito traps can decoy and capture mosquitoes both in bright indoors and in dark outdoors by a tripartite system, heat and near ultraviolet rays produced from the fluorescent lamps installed inside, and carbon dioxide produced when near ultraviolet rays are radiated onto titanium dioxide. Carbon dioxide (CO2) is a gas which is completely harmless to the human body. Decoyed mosquitoes enter the exterminator through the capture windows on the upper part, and then are strongly drawn into the capture net, on the lower part. Once they are drawn into the capture net, they cannot fly away upwards due to the strong current of the ventilator. V-mart superstar photocatalyst mosquito and fly trap is a healthy and environmental friendly product. Easy to use and clean, these products are widely used in bedrooms, living rooms, farms, hospitals, schools, villas, food processing fields, and farms.
