Scale Insects

Scale insects attach themselves to the canes and leaves of your Dendrobium, secreting honeydew as they feed on plant sap. This sugary residue is what creates the sticky coating on the leaf surfaces.

Very Common

How to confirm: Inspect the crevices of the pseudobulbs for small, hard, brown or white bumps that do not move.

Aphid Infestation

Aphids are soft-bodied insects that cluster on new growth and flower buds of Dendrobium kingianum, excreting honeydew as a byproduct of digestion. This substance coats the leaves in a sticky film.

Very Common

How to confirm: Look for tiny, pear-shaped insects, often green or black, clustered on the tender tips of new shoots.

Mealybugs

Mealybugs produce honeydew while feeding on the orchid's nutrients, which can lead to a sticky residue and secondary sooty mold growth. They are often accompanied by a white, cottony appearance.

Common

How to confirm: Search for white, fluffy masses in the leaf axils or at the base of the canes.

3 Improve air circulation around the orchid to prevent secondary sooty mold from developing on the sticky leaves.
warning

Sooty Mold

While not a primary cause, sooty mold is a black fungus that grows specifically on the sticky honeydew left behind by pests. It can eventually coat the Dendrobium leaves, blocking photosynthesis.

Common

How to confirm: Check if the sticky residue is accompanied by a dark, soot-like film covering the leaf surface.
