In the most severe cases, mites will form fine webbing that may cover all or part of the plant. Once a plant is infested, control is difficult. Mite-infested leaves may have a gritty feel or an appearance of being covered with a fine coat of ashes. To control problems, isolate your plant immediately, and dip it or spray it weekly with insecticidal soap. Systemic insecticides are sometimes effective if used quickly.
Aphids are common pests but are easily controlled.
The insects suck sap from the plant and can cause new growth to be distorted. Aphids are found on new growth and the undersides of the leaves. Heavy infestations end with the plant covered in sticky syrup called honeydew. Aphids can be controlled with commonly available houseplant insect sprays. Mealybugs look like tiny white tufts of cotton and are often mistaken for a disease rather than the insect they are.
