Back! Good tip on the alcohol.
I used dishwashing soap and hydrogen peroxide and sprayed neem oil on just the base and on top of the soil. One of my old grafted had aphids too but I think I caught it early.
I think the spider mites came from my new desert rose purchases. I normally separate them from the old ones but they might have jumped to my other adeniums.
(Note: I read somewhere not to use neem oil on adenium leaves.)
