Aphid Infestation

Aphids are sap-sucking insects that excrete honeydew, a sticky substance, onto the leaves of Anthuriums. This honeydew can lead to the growth of black sooty mold on the white spathes and foliage.

Very Common

How to confirm: Inspect the undersides of the leaves and new growth for tiny, pear-shaped insects.

Scale Insects

Scale insects attach themselves to the stems or leaf undersides and secrete honeydew as they feed on the plant's vascular system. This residue creates a persistent sticky film on the Anthurium foliage.

Very Common

How to confirm: Look for small, hard, brownish bumps firmly attached to the petioles or leaf undersides that cannot be easily wiped off.
