What are these nodules that are underneath the leaves and on the stems of this bush everywhere?

I'm in Georgia in April 2020.

I don't know what kind of bush it is, but you can see from the inset photo that it grows back within months after being pruned.

I don't recall seeing these dots in years past.

Should I be doing anything about this?

If these are pests we should get rid of, we'd prefer an organic way, if possible.

Looks like aphids, sucking fluid from the plant. I would use Malathion but I think it is politically incorrect. One alternative is to buy a very large number of lady bugs online.

  • Thanks blacksmith37. I added a new photo; these looks like bugs but not exactly like aphids (google.com/search?q=aphids&source=lnms&tbm=isch) but I guess there are varieties. – Ryan Apr 24 '20 at 15:33

    Malathion would still fix them. – blacksmith37 Apr 25 '20 at 2:21
