I have an adenium obesum that is plagued by mealy bugs that have now spread to my euphorbia obesa.  They have also killed a leaf or two on my pachypodium horombensis, though they appear to have no taste for any of my cacti.  Are there any effective controls against mealy bugs that are safe to use on all these plants?
 
I keep all these plants indoors, in a south-facing window.  If necessary, now that spring has arrived, I can move them outdoors for treatment.  Otherwise, I would prefer a control agent that is safe to use indoors.
