Our pest control put in a bucket called In2Care that has a little net with some powder suspended above the water - mosquito lands on the net, gets the powder on 'em, carries it to the next site and that site gets neutralized. They're designed for commercial campuses but for ~$200/yr it's well worth it for residential also.

They do take a while to take effect, and they do take maintenance, but my experience so far is that they're super effective.
