Aphid Infestation

Aphids are small, sap-sucking insects that pierce the tender leaves of Kalanchoe Passion Thalia to feed. As they consume nutrients, they excrete a sugary substance known as honeydew, which creates the characteristic sticky residue.

Scale Insects

Scale insects attach themselves to the stems and leaf surfaces of Kalanchoe, extracting sap via a proboscis. Similar to aphids, they excrete honeydew that coats the plant in a sticky film.

Sooty Mold Development

While not a direct cause of stickiness, sooty mold is a black fungus that grows specifically on the honeydew left by pests. If your sticky leaves also have a dark, powdery coating, it is a secondary symptom of an existing insect problem.

Common
