Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often found with Anthuriums. They pierce plant cells to feed on sap, leaving behind fine silk webbing as they build colonies across the leaf undersides.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap it to see if tiny crawling specks fall off.

3 Gently wipe leaves with a damp cloth to physically remove webbing and any remaining mite colonies.

warning

Broad Mites

While they do not produce large webs, heavy infestations can cause structural changes in new growth and subtle silk-like textures. They are much smaller than spider mites and harder to see with the naked eye.

Common

How to confirm: Inspect the newest, most tender leaves for distorted, thickened, or puckered growth patterns.

2 Isolate the affected Anthurium from other houseplants immediately to prevent the mites from spreading via air currents or contact.

3 Gently wipe the leaves with a damp cloth to physically remove any remaining mites and debris from the plant surface.

warning

Low Humidity causing leaf desiccation

Extreme lack of humidity can cause the edges of Anthurium leaves to become brittle and fray. In some cases, these tiny broken leaf fibers can be mistaken for fine web-like structures.

Common

How to confirm: Check if the webbing is actually just dried, shriveled leaf margins and use a hygrometer to check ambient humidity.
