Aphid Infestation

Aphids are small, soft-bodied insects that pierce the tender stems and leaves of Gerbera daisies to suck sap. As they feed, they excrete a sugary substance known as honeydew, which creates the characteristic sticky residue on the foliage.

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaf bases of Gerbera plants, feeding on phloem sap. Like aphids, they produce honeydew as a byproduct of their digestion, leading to sticky leaves and potential sooty mold growth.

Common

How to confirm: Look for small, stationary, bump-like structures firmly attached to the stems or leaf petioles.

Whitefly Infestation

Whiteflies congregate on the undersides of Gerbera leaves to feed on plant fluids. Their feeding activity results in honeydew accumulation, which can also attract secondary fungal issues like sooty mold.

Common

Mealybugs

Mealybugs are slow-moving pests that secrete a waxy, white coating and excrete honeydew. While they primarily target nodes and leaf junctions in Gerberas, the resulting sugar residue can coat surrounding leaf surfaces.

Common
