Answer: Ficus benjamina can sometimes be host to scale insects. These look like small brownish or grayish bumps on the stems and undersides of the leaves. Scale insects feed by sucking plant juices and exuding a sticky substance. These pests are best controlled before the populations get too large and the damage too great. Because of their hard protective shells, pesticides aren't very effective. You can squish individual scale insects, or use a cotton swab dipped in rubbing alcohol to dab each pest. Once you get the population under control you'll need to inspect your ficus on a regular basis and squish any new scales you discover. Wish there were an easier way!
