Scale Insects on Weeping Figs (Ficus benjamina)
Falling leaves on weeping figs is common with a change of season. It’s also a common response to insect feeding.
Take a close look at the leaves and stems of your ailing weeping fig. If you find a clear sticky substance, your plant is being attacked by one of several insects.
Examine the stems, undersides of the leaves and the place where the leaf stem, petiole, joins the plant stem. Check for brown bumps that can be scraped off with your finger. These are adult scale insects, a common pest of weeping figs grown indoors. Gently scrape off the scale using your fingernail or an old toothbrush. Then spray the plants with insecticidal soap or Neem to kill the translucent immature scale that are sure to be present. Continue the treatment once a week or so until the scale are no longer present.
Persistence is the key to successfully controlling this pest.
A bit more information: Aphids and mites also secrete honeydew, but are less common problems on weeping figs. Dislodge small populations with a strong blast of water. Make several applications, one week apart, of insectidical soap or Neem if needed to control these pests.
