How to get rid of:
The first step is to kill the adult mealybugs. Dip a q-tip, cotton bud, cotton ball or cotton pad in rubbing alcohol (not 100% isopropyl alcohol). Press that on to every adult you can find, wiping them off the leaves as you go. It works instantly and those evil fluff-balls will turn orangey-brown when dead.
You can also use it weekly for a preventative at 50/50 with alcohol/water.
