Any chance of a closeup photo?
I do not have any experience with the pesticide in question.
I would recommend removing all affected growth before you even think about pesticides. I don't think chemical solutions will resolve an infestation so much as mop up the mites that might be in the area after you remove it.
My solution to the aloe mite has been either surgery (removing an affected branch) or taking out the whole plant (where surgery is not a great option). I have a zero tolerance policy once I have identified a problem. Arborescens and its hybrids seem to get mites a lot, especially on the inflorescences.
Be careful where you toss your mite-infested plants/parts so the mites stay contained. I send them to the landfill in a plastic garbage bag. My spinosissima went that way a couple of years ago and there is now an Aeonium growing in its space.
And take a look at your immediate surroundings and see if you can identify other affected plants in the neighborhood, because reinfestation is a real concern down the road. The mites have to come from somewhere.
