Which porch lights attract the fewest bugs?

Scientists tested a variety of different types of bulbs to see which wavelengths were least attractive to bugs. 

"Overall, the white incandescent light brought in the largest number of insects, about 8.2 per hour. The white LED light bulb that emitted more strongly at the reddish end of the visible spectrum attracted the fewest insects, about 4.5 per hour. Indeed, it lured even fewer insects than the yellow bug light."

I found this study interesting because our porch lights get really buggy and gross.
