@Shades-of-Oregon These are 4 starts with the 'root riot' beginnings. How do they look to you?

Side - yes, those are bugs. Right before rinse/spray

Perhaps they've laid eggs in the soil and are hatching.

Exactly. This is why sprays could never rid me of them, the next generation waits in the soil. In order to break the cycle the soil has to be dealt with, that's the tricky part.

DW is a fan of green house plants. Summertime, they can be carried out to the greenhouse or under the shade of the porch roof. Divided, repotted – Autumn, back they come in the house. Back come the fungus gnats.

Bacillus thuringiensis soil surface treatment seemed to have been mostly ineffective on them. Yellow, sticky traps catch lots of the gnats but green house plants are intended to be attractive. Sticky traps aren't.

We think of the pests as "fungus gnats," only one kind, but they are not. This year and last, they are smaller than usual. Even to my untrained eye, I see the difference.

Aphids. We see the eggs on the underside of leaves, "ah, ha, aphids!" Is this the only place to find aphid eggs? Are there more than one aphid species? Of course there are.

One year, we had a population explosion of black aphids here at home. Never before but that year, they were everywhere! That has been about 6 or 8 years ago and never since. Are all the  green aphids here the same species? I strongly doubt it. The University of Wisconsin says that worldwide, there are about 5,000 aphid species. Cabbage aphids can be a special problem in my garden. The University of Florida says the eggs overwinter in debris on the soil surface. You know, mulch ... humus, compost. Darn them!

can you get some lady bugs for the greenhouse? they often will do a number on many small bugs.

That's not a bad idea. I'll look into it!

DD potted up the experimental plants today. She did much better then the last time she tried. Instead of grasping the very top of the plant she grasped about 3 inches from the root. We looked at the root structure, and DD got to see an air pocket from not tamping the dirt down hard enough the last time.

We saw that there were no roots in the air pocket. DD compared the size and health of the one with the air pocket to the one that didn't, and found it to be less healthy.

Everyone was tamped down most carefully and watered and put back in the greenhouse. Even if they expire from these efforts--which I believe this time were good enough that this is unlikely--they've done a wonderful service in learning for DD.

I use sticky tape for catching gnats other flying insects .or just use a vaseline on paper hang around plants to snag adults. Also use my coffee grinder to grind eggs shells into powder and place a thin layer over the top of the soil so gnats can’t escape or get in the soil. Let soil dry out on the top layer and keep surrounding areas free of standing water. Use a fan over the plants keep a flow of air if possible. All else fails and there is a gross infestation I use a fogger in the greenhouse to eliminate insects. Works great. Unless your greenhouse is heated or warm temps at least 60F lady bugs will not be active.

You have probably seen them before, fluttering through your greenhouse: fungus gnats or sciarid flies. These little mosquito-like...
