If you look at the leaves with a magnifier and see tiny orange dots, you have false spider mites. That's what the damage looks like, in my opinion - you can also wipe the leaves with a tissue to see if any bugs come off. Make sure this plant is quarantined, and any others close by. False spider mites can be treated with repeated applications of pyrethrin.

A good suggestion from philohela. Also wipe the underside of the leaves with a damp cotton ball. If you see tiny dots, it's insects.

Good call. I found the orange dots. Sadly that meant a death sentence. This orchid was in my office. I cannot fuss with spraying etc at work.

That is a pretty heavy infestation. Hope you might find something orchidaceous to lift your spirits (but clean up the area for any stragglers before placement).

How about alcohol?

aww Just read about the death sentence about the orchid. :( Hope you do find another to keep those spirts up.
