Mites attack

Nowdays I am busy fighting mites on my paphs. Good thing they are on totally different level, isolated from my other orchids.
I never saw the actual bugs but here are the symptoms.
Rusty orange traces on the leaves:



And underside:



Indented damages on the leaves:



All the above pictures are of one plant - Paphiopedilum emersonii II, it took the most damage.
I am annoyed at the bugs for ruining my paphs and mad at myself for not paying attention - I probably could check on them more often and notice those pests traces before it's gone so far.

I have used the Safer's Endall insecticide on Monday, then yesterday. Then I freaked out that insecticide could collect in the media and damage the roots. So I unpotted each of them, washed thoroughly plant and pot and potted into fresh chc.

I think I am going to repeat Endall next weekend, meanwhile - will use cotton swab with alcohol to wipe the plants every third day.

I don't know what else can I do.
