Plants infested with mites lose their green color and appear bronzed or washed out. In severe cases, the mites will form a fine webbing that may cover all or part of the plant. Once a plant is infested with mites, control will be difficult. Mite infested leaves may have a gritty feel, or look like they are covered with a fine coat of ashes. Aphids are common on house plant insects but fortunately, are easily controlled.
Aphids 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 cover the plants with a sticky syrup called honeydew. Aphids can be controlled with most commonly available house plant insect sprays. Mealybugs look like little white tufts of cotton so are often mistaken for a disease. They are normally found on the undersides of leaves or on stems at the point where a leaf joins.
