Applying neem directly does have a chance to damage the stems, as I pointed out earlier on in the thread. Just water can be used to dislodge, and use neem watered in for systemic action.

Applying neem directly to the cacti stems can remove the waxy layer so take it easy if you use that method. Some species suffer more than others, and the oily water can dirty your lophs tufts. I'd dislodge them with a clean forceful jet of water. Maybe they all need to go for a shower :grin: And then start to use the neem to for systemic protection/future prevention.
Many insecticides are no good for dealing with mites, and all the worthwhile miticides end up banned.
