The Homemax Electric Mosquito Killer fly trap lamp is designed to effectively eliminate flying insects such as flies, mosquitoes, moths, and other small pests. The lamp uses UV light to attract various insects. At the same time, the device’s gentle but powerful fan creates a downward air stream that mimics human breath flow: This is a natural hunting technique for mosquitos, because of its heat and carbon dioxide appeal. Female mosquitos are attracted by heat and carbon dioxide exhaled by humans to extract human blood that is necessary to produce their offspring. As a result, the UV light used in tandem with the heat and carbon dioxide trap, is incredibly effective in leading mosquitos and other insects into the trap and eventually killing them. Here's how to use it: Placement: Put the Homemax Electric Mosquito Killer lamp in your room in advance and preferably, in the absence of a human in the room. Place it on a table or chair at a distance from the ground. Preparation: Close the windows and doors, turn off other lights in your room, and leave the mosquito killer lamp on during the night. Cleaning: The lamp is easy to clean. Simply remove the insect trap box with a simple twist. Note: This unit is not effective in areas near rivers or unmaintained pools. Keep in mind that for best results, it's essential to follow the usage instructions provided by the manufacturer.
