Often affected plants are sticky, as mealy bugs produce honeydew. Overfertilizing, particularly in winter, can produce succulent growth that is very weak and prone to infestation. Over the past half-century, insecticides have become the main weapon of choice against insect pests. They’re more closely related to scales, mealy bugs, and aphids. The second is indirect damage, where the insects themselves do little or no harm, but transmit bacterial, viral or fungal infection to a crop. These are called "complexes."
