With that much scale, you might want to escalate to the big guns after temporarily eradicating with the "contact" treatments. Expensive, but it works... 1/4 to 1/2 teaspoon Safari granules on the surface of the medium (which over a week or two will get watered in, will get taken up by the roots, and also nail any hiding out in the medium ) is a systemic that works wonders. (Neonicotinoids are bad for bees, but bees aren't hanging out around Cymbidium pseudobulbs so they aren't harmed, you're not spraying it, part of the point of using granules on the medium). Likewise works on Catts... one application often knocks down an infestation permanently, a really bad one might need another treatment in 6 months, but that's it. Most of the time, one and done.
