A while back someone wanted a light made to attract bugs specifically. Here’s the thread. IIRC, it was said that bugs are mostly attracted to the blue spectrum. Like Lightbringer said above, you need to remember that ALL white lights are going to have some blue spectrum light in them. If you truly want to avoid attracting bugs, you need to emit zero blue light. Green, Amber, and Red LEDs should be fine for that. A lot of LED “bug lights” (the ones made to NOT attract bugs) use amber LEDs exclusively.
