Positive phototaxis Insects
Biological phototaxis is a habit of organisms moving closer to or away from light. It is also a type of biological stress and is the result of long-term natural selection. Insects that are active at night like to gather under lights because of their phototaxis. We often say that moths fly into the flame because moths have positive phototaxis.

Mosquitoes prefer white light to yellow light
Studies have shown that mosquitoes are most sensitive to light with a wavelength of 360-450mm. Combining the spectrum, we found that the range of 360-450mm is mainly blue-violet light. This shows that mosquitoes are more sensitive to blue-violet light.
Spectrum chart
Mosquitoes are sensitive to blue-violet light. What is the connection between this and white light?
The color of light is mainly determined by the color temperature. When the color temperature rises to a certain level, the color of light begins to change from dark red to light red to orange to white to Blue, gradually changing. Generally, the higher the color temperature of , the color of light will tend to be cold white, and the content of blue light and will be higher. Yellow light is warm color light, and the content of blue-violet light is less than that of white light.
Night light
In life, whether it is a desk lamp for a desk or a night light for a room where you sleep at night, use as little white light as possible, so that fewer mosquitoes will come to you and cause trouble.
