I have found a pest, or pest eggs or 'something' on my urban yamadori peach I dug up last year. I first noticed these little white patches, some looking like white scale near buds and shoot bases, and some white almost ant-like eggs in cracks in the bark.
I have checked through all my bonsai books pests sections and even online, and can't seem to find what the pest might be? Or possibly it's a reaction the peach is having itself? I brushed it all away 3 months ago and gave the tree a good spray to ward it off, but it's returned.
thanks so much for any input!

for scale, the little white 'eggs' are around 2.5mm long.
