I agree -- either way, defoliate them. That infestation is too far gone to get them under control at this point. They can be immune to many treatments, and eggs hatch all the time. You can leave the smallest very top leaves but spray them well with an oil-based product like Neem. Retreat in a week to get the hatched eggs. Isotox is at Home Depot and systemic and might be the best for your situation given that it is under $20. Avid and Forbid work well but are more costly. They could be the two-spotted mite or the six-spotted mite or even broad mites or all three. It is hard to say. If you have a jeweler's loop or a magnifying glass you might be able to see them better. Here is a two-spotted one. No matter what kind of mites they are, they are bad news.
