My variegated dieffenbachia has this white creamy stuff in spots on its leaves and stems. Can you tell me what to do? It wipes right off but that's not solving the problem.

This is a mealybug infestation on your dieffenbachia. Purchase a ready to spray houseplant insecticide at your local nursery and use it following label directions. Thorough coverage is important, and expect it to take a number of sprays for complete control.
