I've got REALLY tiny brown ants on the pots of my tomato seedlings, indoors under lights. I do not see them digging in the dirt, and I seldom see them actually on the plants. The seedlings look very healthy, no bites taken out of them, good shade of green, etc. What are they eating?

I have an ongoing battle with fungus gnats, although I'm winning that battle now & only see a stray gnat now & again. I use Gnatrol periodically.

My soil is Master Gardener Bumper Crop Organic Gardener's Gold Potting Soil, to which I added time-release Osmocote 15-15-15 and finely-ground eggshell. I cooked the soil before use.

Friend or foe?
