Oleander Scale (Aspidiotus nerii) will attack oleander, orchid vine, palm, peach, olive, pear, and ivy. They inject toxins into the plant, which causes delayed maturity and deformed fruit. Females lay eggs underneath their armor, and crawlers hatch. The adult female is 2.5 mm long and oval shaped with a yellowish body. The adult male is elongate with a brownish yellow body.
Oleander scale can be controlled by natural enemies and does not usually cause economic damage. Preserve the natural enemies by using insecticides for other pests that do not kill beneficial insects. Chemical treatment for oleander scale isn't usually necessary unless the biological control is disrupted by the use of pesticides used for other pests.
