They can cause yellowing and discoloration of leaves, as well as a fine webbing over the plant. Spider mites can be controlled with insecticidal soaps, horticultural oils, or miticides.

Whiteflies: Whiteflies can be found on the undersides of leaves of many ornamental plants such as poinsettias, hibiscus, and citrus trees. They feed on the sap of the plant, causing yellowing and wilting of leaves. Whiteflies can be controlled with insecticidal soaps, horticultural oils, or systemic insecticides.
