Are they ever really all gone? I may not be that critical about them I guess. If a few are floating around it is no big deal. If things are damp a lot the numbers rapidly multiply and get out of hand. At that point it is a problem with me.

I use 50/50 perlite/peat and they are no problem the first planting. I re-use the soil twice and it is the second go-round that the gnats get bad.

If'n your pots go dry every 2-3 days the gnats wont get too thick...at least here at 8000 ft. altitude. I try to use the smallest pot so I can feed a lot, the soil gets dryer faster, I use less soil, and things are easier to move around. Indicas seem to like to go dry between feedings rather than moist all the time and this helps with the flies. Also, an acid growing medium promotes fungus, moss, and mold and that is what the little devils are eating. Bigger pots stay wetter, and are colder in the winter too, and this can cause slow growth and Ph/Nutrient problems.

To me, fungus gnats are like washing my truck...why bother because it is just going to get dirty again anyway. Unless they are slowing the ventilation fan down I just let em buzz.
