Bugs are indeed attracted to UV, remember those bug zapper with UV neons?
Well, CFL are like compact neon lights. BUt not all light tubes emits UV. They sell those yellow CFLs (and yellow incandescent lightbulbs) for just that. Bad side effect: they are yellow. So your vision is all... yellowed?
I've read somewhere that most LED lamps don't emit UV lights, and I am about to test the theory this summer.
Many white LEDs use blue or UV light to excite phosphors, so they should attract bugs too. Here's an explanation,

Not all LED light do so, and many have a very tight light spectrum.
I tried 3 different light bulbs today. After a few hours of LED light, still no bugs whatsoever around them. I'll give this a try over the week-end, but it definitely seems to work better than CFL bulbs!
