The comments saying that other sources of water need to be removed are spot on.

Another technique I've tried which works (observably) well is described in this video: https://www.youtube.com/watch?v=6BhV-o77RqQ

tl;dw: Get a big drum fan with a screen on the back, attached with small/powerful magnets. Mosquitos are such poor flyers that they get pulled against the screen and can't escape, and they pretty quickly desiccate and die. Most other flying insects don't get caught, although there is a bit of collateral (some moths and lacewings, unfortunately). Another benefit of the fan is that you can hang out in front of it and mosquitos mostly won't bother you there either.

I did this in our shared backyard space in Brooklyn and would catch hundreds/thousands of mosquitos per week. Despite that, there were still a ton of mosquitos in the area so it's best combined with other methods of control.

The fans in that video are probably 200-400W, running that nonstop seems pretty wasteful.

Fun to see Dan's videos :) (he made a lot about solar concentration too)

On a larger scale, there's this https://www.youtube.com/watch?v=AI3HE7BcIBk&pp=ygUQbW9zcXVpd... about mosquito factories

Unclear from the video: do you need to use any sort of bait or lure to attract mosquitoes upstream of the fan?

I have a bug catcher that kind of looks like a Dyson bladeless fan but runs in reverse. Inside the ring, there's UV (?) LEDs to attract bugs. Once they fly in, the fan sucks them down into the base where there's a sticky paper. The base has a tight mesh around it so they are trapped if they somehow manage to not hit the sticky paper immediately. We use it for soil gnats but I've also seen some houseflies in there too.

Mosquitos are mostly attracted by CO2, not UV. Mosquito traps often have a bit of smoldering coal in them.

I changed the video link to an updated version where he goes into much more detail. You don't need any lure (I didn't use any), but you can see in the updated link that he places the fans around where his dog sleeps and also uses a bottle of soda with the cap slightly unscrewed to slowly leak CO2.

In general though, if there are enough mosquitos around they will get caught in it without any additional effort.

Nope. They're so light that when they enter the airspace, they get sucked into the net (back) or blown away (front).
