Been doing a bit of research and it seems like this is what I would need for my climate in the Central Valley of CA:

It's way more than I need but seems like I could keep them cool in a dedicated small refrigerator we have in the garage to put them into semi-hibernation as described and get a number of applications out of the order.
Unfortunately can't find any available with free shipping and have to ship overnight so they'd be pretty pricey (about $75 for me), but if they worked well all season, and I didn't have to spray, it would probably be worth it.
I suppose than if I go to biological (need to do more research), I can't go with various pesticides and would have to get biological for other pests, too....
What do you all (or anyone
) think?
ON EDIT: Found a much better price here:

$45 including overnight shipping
BTW, Hydro-Gardens seems to list this species as first choice for Russet Mites (as well as being effective on spider mites).
