There was a discussion about this a few months ago, and someone posted about a homemade contraption. He caught pounds of bugs. Zappers dont get many mosquitos, but lots of heavier insects. They dry up and weigh next to nothing shortly after dieing. The no AC is not a big problem, just read posts about solar aerating etc. All you need is solar panels, deep cycle battery and DC to AC inverter.
I have lots of small BG and shiners, and lots of skeeters and other insects.
