Also there are some comments on that the poison they use is really harmful for marine life, so you shouldn't use it near water. Also personally not sure I like to have poison diffuser next me all time.
The point about harmful poison is very valid though. Definitely good to know and to avoid extended use. I'm less keen on buying it now, even though the protection from bites sounds promising.

At a distance, its CO2 (30 feet away). Closer in, its the sweat. Even closer to target, its body heat.
The CO2 itself doesn't need to be warm or sweaty. Just when the mosquito is close to a target, it switches from the general vicinity (CO2) approach to one that will give it a better lock on.
About 10:35 into it it's about the mosquitos that feed on humans... but its zefrank, you're going to watch it all and chuckle at the humor.
Do you just open it and leave it there?
Anyone tried using those for mosquitoes?
The ecosystem impact is still super important to understand, but it's reasonable to think that other mosquitos, or similar insects, could fill the niche left behind.
Sure, but as with climate change, you may not like the result. I guess there's a fair chance that it won't be "just like now, but no mosquito bites". Mosquito larvae are a big source of food for others, and extensively prey on larvae of other species, keeping those in check. Adult mosquitos are important pollinators, too, and as we're currently discovering with bees, taking out an important pollinator has big consequences and while the ecosystems will adapt, it may well end up shedding very desirable species entirely, ecosystems take a long time to bounce back, and may be a lot less appealing to us afterwards.
Frogs and fish might suffer, too, they'll have to make do with a lot less food when you take mosquitos out, and what takes their niche may not be as palatable. You push these below a sustainable population size in an area, you probably lose them entirely, and their function of keeping insect larvae and adult insects in check. Since we'd like to enjoy mosquito-free summers ourselves, and soon, the time scales we'd typically do such interventions on is way too short for much adaptation in vertebrates to take place, generation times even of frogs and small fish are too long for that. You may end up with ponds that are way emptier and more silent, and with lots more creepy crawlies and possibly a long-term balance that has, say, way more rats, roaches, etc.
I guess it depends on whether the device is durable enough to last that long, and whether or not you’re careful enough to avoid burns with the spoon method!
Assuming your leisure time is worth 20p per minute, the cost is quickly amortized.
On the other hand, I'm put off by this rejection of differing viewpoints:
"While contrarianism is a valuable american (and human) trait, in this situation it is misplaced, mis-informed, and dangerous. An educated man's anti-vaxx, if you will."
... which employs a fairly lazy pejorative to dismiss (people that think perhaps we shouldn't eliminate mosquitos).
I believe I quote Will Durant: "The mosquito is the enemy of civilization" and I am intrigued, generally, by the idea of eliminating mosquitos ... but I also adhere to the precautionary principal.
Maybe save a breeding stock and frozen eggs, etc., in case there is some hidden consequence we didn't think of ?
Some mayflies may look like mosquitoes, but they don't bite and are mostly harmless. It doesn't mean they are not annoying, especially when there are lots of them, and if that's a problem, UV light traps work great.
Thinking about it:
If I leave the window open with the light on in summer there will be hundreds of mosquitoes in the room (together with ~50% other critters). Even if no one was inside.
Window open without light: a dozen mosquitoes at max (as counted by suddenly switching the light on).
Whatever is known about other species is not correct about our breed.
Or fish food.
