Silent design, night use will not affect sleep. Without any harmful substances, it can be used by infants and pregnant women at home. The nine-leaf vortex catches mosquitoes in a large area, and the silent DC fan rotates at high speed. The spiral airflow is formed by large suction, which improves the mosquito absorption rate and prevents mosquitoes from escaping. Upgrade UV violet light, 360 light wave induction, reflection technology, so that the frequency conversion light wave coverage is wider, the distance is longer, and the mosquito attracting effect is doubled. The mosquito killing effect is improved by 200% Mosquitoes have phototaxis, and they love light with wavelength of 365NM. Their eye structure is different from that of human beings. Light invisible to human eyes is a dazzling light source for mosquitoes. The special LED lamp with 365NM wavelength UV purple light wave is adopted by the Star Mosquito Killer to attract mosquitoes efficiently, which has more outstanding mosquito attracting effect. Double mosquito killing, strong suction and high electric shock, new black technology mosquito killer, strong suction and deadly electric shock make mosquitoes have nowhere to escape. The mosquito killing effect is obviously improved by 80%. quantity of delivery:1pc size of product:11.8*18.8cm color of product:white
