Young third nymphs that have not completely secreted their waxy covering are also susceptible. Nymphs pass through a couple of moults before becoming adults. This will force ants to climb the ficus trunk and get stuck in the sticky material. As females age, they become a uniform brown colour.

Settled nymphs may spend their entire life in the same spot without moving as they mature into adults. 1. Pruning infected branches is often the easiest and surest solution if you catch the infestation while it is still light. Inspect the plant thoro Even after the insects are killed, many of the scales and the sooty mold will remain on the plants and continue to disfigure them. Infested plants appear water stressed, leaves turn yellow and may drop prematurely, and plant parts that remain heavily infested may die. The brown soft scale is an exception; it has multiple generations and females and nymphs can be present throughout the year. However, conserving resident natural enemies is a more efficient and longer lasting strategy than buying and releasing beneficials in gardens and landscapes. It's important to treat the entire plant, as scale can be present on stems, the undersides of leaves, and along the base of the plant.
