In addition to targeting a specific wavelength of light and specific odor, there are a lot of mosquito habits worth knowing. The mosquito's weapon is in the head, and the mosquito's head is full of short antennae, with a series of important sensors on its undercoat. Through chemical sensors, mosquitoes can sense carbon dioxide and lactic acid gas more than 50 meters away. When mammals, birds and people breathe, they emit the gas. The humidity and temperature sensors, mosquitoes can find the wet temperature of gas flow, around the animal and the human body surface enveloped in this way, even in the dark environment, it can also locate the human and animal attack.

　　In addition, mosquitoes are cold-blooded, unable to control their body temperature, and its metabolism is subject to changes in temperature. When the temperature is below 10, mosquitoes die because they can't stand hypothermia. The temperature most suitable for mosquito activity and the temperature suitable for people's life are between 25-28 degrees centigrade. Therefore, low temperature will affect the activity of mosquitoes, through air-conditioning and other ways to reduce the room temperature, can play a certain effect of mosquito repellent.

　　Water is the mosquito to complete the process essential condition for the growth, so water and moist environment is an important reason to attract mosquitoes, promptly put the small water home clean, can effectively inhibit the proliferation of mosquitoes.
