Scale Insects

Scale insects are stationary pests that pierce the plant tissue to suck sap, excreting a sugary substance known as honeydew. This residue creates the characteristic sticky film on the leaves of Ficus microcarpa.

Aphid Infestation

Aphids are soft-bodied insects that congregate on new growth and leaf undersides, feeding on plant fluids and producing honeydew. This can cause the leaves of your Chinese Banyan to become sticky and eventually distorted.

Very Common

Sooty Mold

While not a primary cause, sooty mold is a fungus that grows specifically on the sticky honeydew left by other pests. It appears as a black, powdery coating that can block light from reaching the Ficus leaves.
