Most Common Gold Dust Plant Pests:
Identification and Treatment Guide

Gold dust plant, also known as aucuba japonica, is a popular ornamental shrub that is commonly grown for its glossy evergreen leaves that are splashed with yellow spots. While these plants are relatively easy to care for, they are not immune to pest infestations. In this article, we will discuss the most common gold dust plant pests, how to identify them, and the best treatment options.

Spider Mites

Spider mites are a type of arachnid that feed on the sap of gold dust plants. These pests are tiny and often go unnoticed until there is a severe infestation. Signs of spider mites include yellowing leaves, webbing on the plant, and fine stippling or speckling on the leaves.

Treatment: The best way to treat spider mites is to spray the plant with insecticidal soap or neem oil. These products will suffocate the mites without harming the plant. You may need to repeat the treatment every few days until the infestation is under control.

Scale Insects

Scale insects are small, oval-shaped pests that attach themselves to the leaves and stems of gold dust plants. They secrete a sticky substance called honeydew, which can attract other pests like ants and sooty mold. Signs of a scale insect infestation include yellowing leaves, stunted growth, and a sticky residue on the plant.

Treatment: The best way to treat scale insects is to use horticultural oil or neem oil. These products will suffocate the scales without harming the plant. You may need to repeat the treatment every few days until the infestation is under control.

Mealybugs

Mealybugs are small, white insects that feed on the sap of gold dust plants. They secrete a waxy substance that can protect them from insecticides. Signs of a mealybug infestation include yellowing leaves, stunted growth, and a white, cottony substance on the plant.

Treatment: The best way to treat mealybugs is to use a systemic insecticide. Systemic insecticides are absorbed by the plant and can kill mealybugs that are hidden in crevices or protected by their waxy coating. You may need to repeat the treatment every few weeks until the infestation is under control.
