Tiny flies, not fruit flies?

[FrostyMoanyWind]

Don't think they're fruit flies. Well, if they are, they're clever ones at any rate as none have yet gone into my usually successful fruit fly trap.

They're really annoying, centred around my new plant and the other side of the room by the snail tank. I can only assume they've hatched from the soil I used to line the tank and fill the plant pot. So probably nothing will change if I renew the soil, I'll just get a fresh batch of flies.

They are tiny and annoying. How to get rid?

Ginky yes, if it's the soil/fungus gnats, the sand really does work. I had bloody loads of the little buggers every single day, but within a day of putting 2 inches of sand in the pot, they were all gone, never to return.

Help! I'm bumping this because I have loads of this bastards but no flowers! Help!!
