i read you can use insecticide wipes to get rid of gnats. wipe around the edge of the pot and then put the wipe in the pot under the plant.

i hope this helps!

You can put a peeled slice of potato on the top of the soil and it will attract larvae up to it. Just pick it up and look under it after a day or so and you should see some larvae that you can pick out.

You should also buy some of these yellow sticky card traps to catch the adults. Put a couple near your plants, the yellow attracts adults and they get stuck and die, without using poisons!

I think a layer of sand on the top of your soil will suffocate the larvae as well, if you wanted to try that.
