1.Due to mosquitoes are sensitive to light and heat sources. They like dark, humid, and warm places, so when nobody is at home, it is more effective to put the mosquito killer lamp in the kitchen, storage room, etc. 2.Mosquitoes usually infest at night, and mosquitoes are the most rampant at 7~8PM in bedroom. You can turn on the mosquito killing lamp in advance to remove mosquitoes in advance for your bedroom and enjoy a mosquito-free night. 3.Within one Month, please do not open the chassis of the mosquito killer container to prevent undehydrated mosquitoes from escaping. Working Principle :Using the phototaxis of mosquitoes, the mosquito trap lamp beads emit light to lure mosquitoes, plus the micro-temperature effect to simulate the humid atmosphere of carbon dioxide, the fan stirs the surrounding air to form a vortex. Once the mosquito is sucked into the capture window, it will not escape the vortex and captured. After about a month, the mosquitoes were dehydrated to death.
