Often, if you go to the right retail store, the associates will mention something along the lines of “LED bulbs tend not to attract insects” as an informal sales pitch - the manufacturers certainly never state this.
Anecdotally, I use a 5000K 1600 lumen porch lamp, and the bug attraction is far lower than the previous bulb (a warmer CFL bulb, not sure if ~800 or ~1200 lumens). There are still some bugs, but it seems to be limited varieties… The warmer-white LED bulbs, in my experience, attract even fewer bugs, but I like having a big harsh daylight porch lamp.
