I don't know what they are but they have been building up over the years. Here is what I have on so many plants lately. (not a mealy bug) Thought it was a wooly aphid but I don't think it is.

I have these on many plants including lilies, hydrangeas, solanums, and several other plants.

I sprayed with Bayer Complete Insect Killer yesterday (24 hour contact, 3 months in the ground) and most are gone but some are still here that I must've missed. Here are some photos from this morning. Number 1, 2, and 5 are the same bug and I believe it is an adult. The other two are different bugs but I think they are nymphs.
