What's with the anti-nature attitude? Bugs perform tons of ecosystem services like pollination, food, decomposition, eating pests, fertilization, etc. A complete food web is dynamically stable, preventing infestations. This is why monoculture agriculture necessitates pesticides/herbicides/fungicides, btw.

Insects could live without us. We couldn't live without the insects. My interest is entirely selfish. ;)

Of course, this is getting into much bigger issues than just streetlights...
