Many people with mosquito issues around here (Sweden) uses something like https://www.clasohlson.com/se/Mosquito-Magnet/p/31-7190 which burns propane to produce Co2 to lure in mosquitoes and then sucks them in with a fan towards a metal grid to zap them with electricity.

Non-poisonous and from what I've heard fairly effective. Not sure if these exists in the US?

I used one of these for two weeks. It killed many mosquitos, yes, but it killed far, far more non-mosquito pollinators which ultimately is not acceptable to me. If I didn't care about the other insects, I'd just spray my yard with poison and be done with it.

As always, YMMV

I tried one of these once. It was annoying, seemed kind of dangerous, and wasn't especially effective. This is much better:

Admittedly, it is more annoying to refill.

That being said, depending on your mosquito species, the Biogents chemical attractant may be even more effective than CO2.

We have one with a fan and a coated UV light that does similar, it just sucks them in till they dehydrate/starve

catches moths as well, so it's not as eco friendly.

Does it actually attract mosquitoes? I didn't think they'd be attracted to UV light.

you usually use a chemical attractant insert along with the device. I have one of these. Success seems to be hit or miss. I've run one for a year and it seems to only accidentally catch mosquitos, and that's not a unique outcome. But then others seem to have massive success.

I'm going off-topic, but what's up with that font with the ugly square-bottomed lower-case g's? I've been seeing it everywhere. It's not good.

I thought it couldn't be that bad but wow, that's bad. The first font-family entry is Clas Ohlson Sans Web, so presumably a font developed for Clas Ohlson? Looking at samples online, J and to a lesser extend t are similarly hideous.

You might even say it's... Grotesk.

Very cool where can I get on?

I have seen a similar thing at https://us.biogents.com/

Haven't used it so I can't comment on its effectiveness

My in-laws use a system like this, maybe the same one. It uses a CO2 tank rather than burning propane. He runs it 24/7 and he needs to refill the CO2 tank every 1-2 weeks iirc so it's definitely more expensive to run than the death bucket. I think it's a 20 pound tank like you'd see on a homebrew keg system. When he showed it to me, it had caught an absolutely nightmarish number of mosquitoes over the course of a couple days. Like maybe half a liter to a liter in volume squirming around in the net. It made me queasy honestly. I didn't notice anything like bees or butterflies in the trap but I didn't look very closely.

Don't worry, when you press them into a party and fry em up, they're quite moreish

How is that better than what the article describes? You need gas, electricity (outdoors!) and get constant fan noise.

I guess it depends a lot on your situation, but for OP's method to be effective you need to out-compete other breeding grounds in not only your backyard but also X feet/meters away (whatever distance mosquitoes typically fly to "hunt").

If there's a nice shallow pond on the property line 100 feet from your porch (or water filled tires at the sloppy neighbour or whatever it might be), I seriously doubt the efficacy of the method in the article.

This thing would lure in any mosquitoes (and unfortunately other things, as per sibling comment) that fly in your backyard, wherever they come from.

For electricity: That also of course depends, but around here it's not uncommon to have an outlet on the outside of some garage or outbuilding or something. The product I linked have a 50 feet cord as well. The fan noise has not been noticeable at all when I've seen it.
