Scale Insects

Scale insects are stationary pests that pierce the thick, succulent leaves of the Hoya compacta to suck sap, excreting a sugary substance known as honeydew. This residue is the primary cause of stickiness on the tightly curled foliage.

Very Common

Mealybugs

Mealybugs attach to the nodes and leaf junctions of the Hoya, feeding on plant fluids and producing sticky honeydew as a byproduct. Their presence is often accompanied by white, cottony clusters.

Very Common

Aphids

Aphids are mobile sap-sucking insects that congregate on new growth or tender parts of the Hoya compacta, leaving behind sticky honeydew residue as they feed.

Common

Excessive Liquid Fertilizer Residue

Over-application of water-soluble fertilizers can lead to salt and sugar buildup on the leaf surface, which becomes tacky as the water evaporates.

Common
lightbulb
How to confirm: Wipe a leaf with a damp cloth; if the stickiness disappears but returns after fertilization, it is likely mineral/fertilizer residue.

2 Flush the soil with plenty of fresh water to leach out excess fertilizer salts and prevent further buildup.
