What is your growing medium?
If you're into soil or soil-less, then I like to use predatory nematodes. Added to the soil they're voracious hunters of gnat larvae.

worked for me.
That's because of the base material of the sand, most likely. In other words, the beach sand is likely calcareous in composition (a bit of vinegar will tell you immediately), whereas the paving sand was likely silicaceous. Completely unrelated to note, you cannot use silicaceous sands when rearing juvenile sharks as it is SO abrasive it abrades their skin to the point of infection and death. Calcareous sands only.I've found that cheap paving sand works best. I tried horticultural, flushed, beach, etc., but the paving sand has the best qualities: highly reflective, irregular sized bits of aggregate (tighter compaction), affordable, and easily obtainable.

I'm wondering if I should even say what I want to say, so right now I just won't and see what comes of it. I will say this much--when all I was dealing with were fungus gnats they were incredibly easy to control by simply putting sand on top of the pots.
Never thought about the differences in sand composition. Good point there.
I still remember being on a beautiful white sand beach once and being told that they're the result of parrotfish chomping on coral. Millions of years of pebble poops built up. Why someone would tell me that, I still have no idea...
Because everybody poops and poop is what makes the world go 'round? It's more than parrotfish. If you've ever been diving in tropical locations you'll see other fishes pooping sand, too, but I would have to guess that parrotfish make the largest contribution. They're also very tasty eating.Never thought about the differences in sand composition. Good point there.

I've had those pesky little buggers in the past and Azamax work beter than anything else but a multi level attack works best:
1. yellow, sticky traps for for the flying adults
2. Azamax drench of the soil
3. Azamax spraying down the plants.
I would continue this procedure into the next crop or two for security. Then I use it every so often just in case. No problems since.....
