The Science Behind Insects' Attraction to Light Bulbs in Your Home.
Scientists at Imperial College London have discovered that insects are not actually attracted to light bulbs, but rather their navigational abilities are disrupted by artificial lighting. Using high-resolution motion capture cameras and stereographic video recording, the scientists found that insects turn their backs towards the light source, creating flight paths perpendicular to it. The multitude of artificial lights causes confusion in their navigation, trapping them in a flight path around the bulb without being able to escape.
