Predatory fish. Chironomid midges are a major component of the diet of
many fish species. In particular, bottom-feeding fishes, such as
catfish and carp, consume large numbers of midge larvae. However, the
feeding of these fishes has, generally, not been shown to reduce adult
midge populations below nuisance levels adjacent to habitats where
there were large larval populations. You might want to contact your
local NC Wildlife Resources Commission office for advice on stocking
The effectiveness of this approach is going to depend entirely on the habitat in which the fish are introduced and if it is large enough to sustain them.
Other options to deal with the existing adult population might include bats or dragon flies (I have no sourced reference of the effectiveness of either of those for this use).
Bait lights will work to the degree you scale it to. By that I mean, if the neighborhood continues using flood lights/yard illumination, you will likely be proportionally splitting off some of the horde from where they normally group up. If you can gain the cooperation of the neighborhood in shutting off most of their lights for a few nights while you bait them, you should get more of a turnout.
Lighting Issues. If you live in a near a pond or in a lakeside
community, you might try getting advice from your local government or
from a lighting consultant concerning the type of public lighting in
your neighborhood. It may be possible to reduce lighting or switch
from the typical metal halide streetlight to one that is less
attractive to midges, such as the use of high-pressure sodium lamps.
There might be a situation where you would use brighter lights in an
non-occupied area to attract them away from houses or where people are
active outdoors. On the personal front, reduce or eliminate exterior
lighting at night around your house. Close window shades. Use subdued
walkway/landscape type lighting if you wish. Don’t burn lampposts or
floodlights except when needed. (source)
After having successfully baited the mass of them away from the neighborhood, you will still need some way to deal with the overgrown population (capture/kill) or else they will likely return to the neighborhood after the situation normalizes.
