Default Mites on echinacea

Hello!
I was wondering if any of you could offer any advice on dealing with mites that damage the flower buds of echinacea? This problem happened to me last year, and I'm seeing it on new plants I raised from seed last year. The buds come out deformed and some have no petals left at all.

I have had some problems with aster yellows on purple coneflower transmitted by leafhoppers but pale purple coneflower has not been affected. Mites also affect purple coneflower, the coneflower rosette mite.

I've just about given up on purple coneflower because of all the problems, I don't use any chemical means to defeat pests and pathogens but it is disheartening to lose a beloved plant in my garden because of these problems.

Hmmmm, looks like there's not much one can do then, huh? It's ironic because everything you ever read about purple coneflower talks about how care free they are. The plant isn't technical native to my region, anyway, so I guess I'll just let them fend for themselves.
I was thinking of trying neem oil, but I don't know if that would cause problems for other critters later on. Does anyone know about that? I'll also commend them to Saint Fiacre for a blessing and hope that the predatory mites catch up.

Washing them off with some soapy water should reduce them a bit, and doesn't leave a lasting effect on the leaves.
