I'm growing oranges, lemons, and grapefruit for the first time. What pests will I have to spray for?

A number of common pests attack citrus. The usual suspects include the following. Whiteflies are small white insects that flutter around plants. Scale insects, which resemble bumps on plant stems, leaves, and fruit, and are difficult to spot.  Mealybugs look like small clusters of cotton. Mealybugs particularly like hiding out where stems meet the trunk or along the veins of a leaf. Sooty mold looks like a powdery black substance on the leaves. Sooty mold typically grows on the honeydew left by aphids or scale insects. Combat pests outdoors by using horticultural oil or insecticidal soap applied directly to the foliage. Indoors, use insecticidal soap or an insecticide designed for indoor use. Note any limitations on the use of fruit after spraying with a pesticide.
