Get a cheap box fan, cheap mosquito netting type material, and duct-tape.
Cut the netting to size and tape it to the fan so that anything that goes through the fan gets caught in the net.
Put it in shaded places - bonus if its around doors.
Mosquitoes are not strong flyers, and when hunting or looking for a place to rest will get sucked in and can't get out.
I've killed - without exaggeration - thousands doing this.
Not a silver bullet (what is?) but as part of a defense-in-depth strategy this is insanely easy - and kind of fun.
n.b. I've been hospitalized with west nile - this is fun :-)
Works pretty well for ventilating enclosed spaces, too—just make sure the fan points inward, pumping positive pressure into the space, so there’s a steady outward flow from the rest of the door/window/whatever.
Although it's absolute hell on plastics, DEET is incredibly effective as a mosquito repellent. At least in the US, you can buy 99%+ pure DEET at Home Depot.
I can't find it now, but I remember reading about a person that used a box fan, some type of mesh fabric, and dry ice to create an insect trap that was apparently catching pounds of bugs every week.

At home / in camp, obviosuly put nets everywhere and turn off interior lights when opening doors. If there aren't too many mosquitoes UV traps can make things bearable, but if you're near standing water at dusk you'll still get eaten alive.
Last year I came across a water-filled stump that was teeming with larvae swimming around in it. Dropped a piece of a dunk in, came back 24 hours later and the water was clear.
Thats a good idea but don't think that by covering few neighbors you are covered - they can easily fly 5km depending on species if they have reason or get carried by wind. And all you need is ie one old tire laying around on the ground.
