I had some late flowering spider mites this season. I did damage control with water in a good misting spray bottle. I would spray/wash all leaves top and bottom (only leaves, not flowers) with a blast from the sprayer and run my fingers over the leaves. Starting at the top, and working down. This is really time consuming, and not completely effective, but it's safe for you, knocks most of them off and saves some of your hard work from being messed with.
After I chopped more hatched, and they started congregating at the tops of the cut branches, and I killed them all within a day. There was no detriment to my crop.
Good luck!
