Small gray bugs
Okay, these are tiny little guys, only a few mm long, they're gray, and kind of football shaped, if you elongated the football to about twice its normal length. They look more like seeds than bugs. But, seeds don't come running out of the soil when the plant is watered. Neem oil and "garden safe" pesticides have not worked so far. Any clue as to what these things are and how to get rid of them? Currently, they're only in my Grewia, which is surprising since my collection is fairly close quartered. There's nothing different about the soil in this pot. The only difference is that this tree is a semi-cascade, so the pot is a bit deeper.
Okay... root aphids, a search lead me to this page:

The picture looks very much like the aphids in question. Now, how do you get rid of them? It says there's no know chemical control for this particular root aphid species, but does that include all root aphid species? And why are they only in the one pot?
