Ecologist Michael Justice performed an experiment to determine the type of residential light that attracts the least amount of bugs. He used six lighting types inside of an insect trap each night during the summer. Justice also made efforts to equalize the effects of weather and the moon's irradiance. His findings were presented at the 2016 American Association for the Advancement of Science (AAAS) conference. Justice wrote, “The incandescent bulb had the highest capture rate, followed by CFL, halogen, LED with a cool color temperature, and the “bug” light.
An LED with a warm color temperature had the lowest capture rate.” To sum up his findings, Justice added, “From an ecological perspective, LEDs with a warm color temperature should be favored because they attract the fewest insects
