Answer:Ficus trees can become host to scale insect and mealy bugs when grown indoors. Scales look like little bumps on the stems and undersides of the leaves; mealybugs look like little tufts of cotton and they tend to congregate on the undersides of leaves and in crotches where stems and branches meet the trunk of the tree. Both these pests are classified as sucking insects; they excrete a sticky substance known as honeydew. This sticky substance falls on lower leaves and you'll see a shiny residue on the upper surfaces of these leaves.
