I tried the water based approach before and didn't work, but this may be a good one. What does work for me is a CO2 based trap. I have 4 neighbors on the street using them now. Mosquitos follow CO2 to find their targets, and get sucked into the bucket. Its kind of expensive (upfront cost of about $200 then about $60 in CO2 per summer, but I have a large bag full of mosquitos regularly so i know it works. And I can tell when the CO2 runs out because mosquiotos are back.

CO2 seems to be extremely effective in general, but what I really want is for someone to create a commercial version of something I saw DIY'd on Reddit. They used safely-contained smoldering coals placed behind a high-speed outdoor fan, with mosquito netting secured loosely (but with no gaps) to the front of the fan.
The fan intakes CO2 from the coals... and blows it out into the neighborhood (I think he claimed it was detectable at 60 or 80 feet?) to essentially advertise. When mosquitos approach, they're sucked into the fan intake, and can't get out past the blades and netting. Most are dead by morning, and the rest you spray down before removal. IIRC he said he only needed to do it one night every few weeks to keep the population unnoticeable, and he'd wake up to thousands in the netting the next morning.
I'm sketched-out by the CO2 mechanism, so I've never tried it, but figuring out an extremely slow release mechanism from a small tank seems doable. Maybe one day I'll get around to tinkering with it. My neighborhood started spraying, so it hasn't been bad enough to put much effort into.
I don't have a mosquito trapping solution, but wanted to also offer help to anyone harassed by mosquitos: Despite being a magnet for mosquitos, I've found a coconut-based moisturiser to be more effective than even "tropical-strength" repellants. I used to use various repellants and still get bitten, but this moisturiser is hilariously effective. (Brand is Palmers but others might work too.)
The company has always made it as a typical moisturiser/lotion but then started hearing from RV/caravan/campers that it was keeping mosquitoes away.
