Default Propane-powered Mosquito Traps: What's the deal? Do they work?

FOAD, dickhead...

Certainly it's know what attracts skeeters to live critters; what's
not so clear is that the artificially-generated attempts are effective.


Corse its perfectly possible to provide the CO2, heat and
odours etc that are the same as what live humans produce.


Not w/o the same generating mechanism, no...there's more than just CO2
and the odors aren't all that simple to generate.

....

That means that those other devices are perfectly viable mosquito traps, stupid.


But it also means the CO2-baited traps ain't worth the extra expense
which I presumed anybody w/ the least amount of intelligence would
realize is all that was said....

....

Field trials for commercially available and experimental mosquito
traps variously baited with light, carbon dioxide, octenol, or
combinations of these were evaluated ...The total number of
mosquitoes and number of each species captured during the test were
compared using 8 × 8 and 5 x 5 Latin square designs based on trap
location. ... Traps baited with octenol captured significantly fewer
Cx. pipiens than those not baited with octenol. Likewise, no Cx.
orientalis were captured in octenol-baited traps. Host-seeking
activity showed a similar bimodal pattern for all species captured.
... Significantly greater numbers of mosquitoes were captured with
mosquito traps using counterflow technology when compared to standard
light and carbon dioxide-baited traps.


IOW, just a fan to suck the critters in and trap 'em was more effective
than the expensive, fancy traps.
