What's the verdict on these things? *Are they effective?
I've seen no independent testing results that indicated they're more
effective than alternatives tested--which is pretty much why they're
not particularly widespread; it appears that most of the glowing
testimonials are either sponsored "research" (read advertising hype)
or self-justification of the $$ spent to avoid admitting have been suckered.
It's been a while since I looked but google found several studies a
while back from various land-grant universities, etc., that
concluded they're of minimal help if any...
That can only be because some werent that well designed.
Its been known for a long time now what attracts mosquitos.
May be so;
No maybe about it.
You're taking that away from the rest of the sentence it was modifying to infer a totally different meaning from what
I said...

You're lying.

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.

as noted the testing results I remember seeing didn't demonstrate significantly higher preferential capture rates
for the devices.
Higher than what ? *If they capture anything,
they must be working better than no device at all.
Than the other devices in the test, obviously...

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

Particularly, they weren't effective for anything even
remotely approaching the acreage coverage claims iirc...
Different matter entirely.
But still a portion of the test and how effective they are for practical use.

Wrong on that last.

So what if even if they were 100% effective in a small radius--you going to limit your position into that area?

You havent established that they only work over a small area.

The devices are typically advertised as covering sizable fractions of an acre.

Irrelevant if you dont need as much as that.

There are likely newer studies available; others are welcome to pursue it. *Seems like it was LSU extension
maybe(???) that had some of the
most extensive that I saw previously but I'm not certain of that any longer....
Sounds like you are comprehensively garbling what they actually said.
No;

Yep.

the conclusions were they were no more effective than other traps tested w/o the CO2 attractants...

Easy to claim. Have fun actually substantiating that claim.

As they say, "you can look it up"...

As they say,

YOU made that claim about what they purportedly said.

YOU get to demonstrate that any actually said what you claim they said.

THATS how it works.

That's how the ignorant think it works. More knowledgeable persons
simply refute, then may or may not chastise.

Any device may kill tons of mosquitoes. Whether those kills provide
adequate relief is another story entirely.

Gas/smoke/heat emitting devices are obviously dependent on the speed
and direction of the wind, a severe limitation of effectiveness.

As a former PCO who lives in the woods with a SO who is outdoors
morning to usually late night I recommend materials that both kill and
repel. I use Tempo Ultra WP (available on eBay at nearly PCO $)
applied at a 0.10 concentration with a Birchmeier 2-1/2 gallon sprayer
(the Cadillac of sprayers).

The big downside is that pyrethrin insecticides, while safe for
mammals, aren't selective; they kill pretty much everything.

They are also quickly degraded by UV light (@48 hrs direct sunlight)
and while they will stick pretty good during a heavy rain, two rains
and they're in the dirt (it's been a tough year here in this regard,
it's rained twice every 3-4 days).

Another consideration is swimming pools. Get much in one by spray or
tracking) and you'll have algae growing like you've never seen before.

I spray everything in the vicinity; trees, grass, bushes, walls, deck
railing, being careful of overspray drift in the pool.

SWMBO sits out in her bikini unmolested by anything but me.

No "electronic" pest repellent/killer has been demonstrated to have
much effectiveness outdoors.

(I once met a client at a pet store and we put his new $50 electronic
rodent device in an aquarium full of mice. They immediately crawled
all over it.)
