Scale Insects

Scale insects attach to the underside of Anthurium leaves and suck sap, excreting a sugary substance known as honeydew which creates a sticky residue. This often leads to secondary issues like sooty mold growth on the leaf surfaces.

Aphid Infestation

Aphids are soft-bodied insects that congregate on new growth and leaf undersides, feeding on plant fluids and secreting sticky honeydew. They are particularly attracted to the tender, emerging spathes and leaves of Anthuriums.

Very Common
