I use Dr.Bronners Peppermint Soap. Then I follow up a week later with a dusting of diatomaceous earth. I put it in the exhaust side of a shop vac and fog the whole underside of the tree.

Note.....A healthy tree typically shuns spider mites. There is an underlying weakness in the tree. Get it looked at by an arborist for proper soil balance of pH and fertility. Something is weakening the tree.

I’ve used this too! Great results.
