Hi CG, Yes, Safer's Insecticidal Soap is a nice safe one to try and is readily available, almost any store that has a plant section. Or you might look for something that is labelled as a miticide -- even better. I've never used Neem Oil so can't be of help there. If you have any way of upping the humidity, that would be worthwhile as mites love it hot and dry. If there aren't too many plants, wiping the leaves, particularly on the underside with isopropyl alcohol and water half and half is also a help.
