Aphid Infestation

Aphids are small, soft-bodied insects that pierce the succulent leaves of Kalanchoe to suck out sap, excreting a sugary substance known as honeydew. This residue is characteristically sticky and can lead to secondary fungal growth like sooty mold.

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaves of Kalanchoe, feeding on plant fluids and producing honeydew as a byproduct. Unlike aphids, these may appear as stationary, waxy bumps that are harder to detect at first glance.

Very Common

Mealybug Infestation

Mealybugs are slow-moving pests that produce a sticky residue and are often covered in a white, cottony fluff. They thrive in the crevices of Kalanchoe leaf junctions and can cause significant plant decline if left untreated.

Common

Excessive Liquid Fertilizer Residue

Applying water-soluble fertilizers too frequently or in high concentrations can leave dried mineral and sugar deposits on the leaf surface. This creates a tacky film that mimics insect honeydew but lacks living pests.

Common

How to confirm: Wipe a leaf with a damp cloth; if the stickiness disappears completely without seeing insects, it is likely residue.
