White Lightbulbs
Generally, insects can see three different colors—ultraviolet, blue, and green—so they’re primarily attracted to lights that emit cool tones, according to David Moore of Dodson Pest Control, which operates in the Mid Atlantic and southern regions of the U.S.
So, if you have LED lights that emit a white or blue color, your space is likely much more attractive to pests. To make things less inviting, invest in yellow and “warm” lightbulbs, especially outdoors.
