From what you described and what I see...these are definitely fungus gnats. I'm trying to be careful about how much I water and how often, ect....but these things were on my plants when they dried out....but they definitely multiply when I water....I never soak the soil, just get it moist.

These things are pissing me off. I was thinking, what about using an insecticide like Sevendust for Vegetables and fruits? If they won't harm veggies or fruit plants, shouldn't harm these right?
