You could remove all the soil and put in new soil. Even doing this the pest can return and/or be on the roots of your plants.

there is a biologicol control...it is a beetle that feeds on all stages of mealybugs called crypts. http://www.buglogical.com/mealybug-destroyer-cryptolaemus/

Chemical controls would require a systemic type insecticide such as thiacloprid, sold as Provado Ultimate Bug Killer Ready-to-Use or Provado Ultimate Bug Killer Concentrate 2,or acetamiprid (Scotts Bug Clear Ultra concentrate or Bug Clear Ultra Gun) and/or thiamethoxam (Westland Plant Rescue Bug Killer Ormanental Plants). I would recommend a drench treatment.
