considering the prevalence of flying biting bugs (weta exluded)
I have been looking into mosquito abatement and traps.

In the U.S there are a few top end models @$400-$600. a pop that will rid mosquitos up to an area of near a 1/2 acre.

The,"mosquito deleto" uses propane to release carbon dioxide-what we breath out- coupled with small amounts of heat. This device sits near a vacuum that you keep plugged in 24/7.

Bugs think they see a warm human, fly by for a quick bite,and get sucked up

Anything like this in N.Z. They make cheaper models $150 U.S but they require replacement parts every 2 months or so. I would rather have the vacuum type as it appears to be highly effective.
