Spider Mites (Tetranychidae)

The presence of fine webbing is a classic sign of spider mite infestations, which thrive in the low-humidity environments often found with Anthuriums. These microscopic pests pierce plant cells to suck sap, causing stippling and eventual leaf yellowing.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap it sharply to see if tiny specks begin to crawl on the paper.

Cheyletiellus mites

While less common than spider mites, these predatory mites can occasionally overpopulate and create visible silk-like structures. They are often found in much higher densities when the environment is warm and dry.

How to confirm: Inspect the undersides of the leaves and the junctions between petioles for larger, more active moving dots.

3 Gently wipe the leaves with a damp cloth to physically remove webbing and any visible mite clusters.

warning

Extreme Low Humidity causing Desiccation

Very low humidity can cause the leaf margins to dry out and become brittle; in some cases, microscopic structural breakdown of plant fibers or secondary fungal growth can appear as fine, hair-like filaments.

Common

How to confirm: Use a hygrometer to check if your ambient humidity is consistently below 50%, which is stressful for Nevada Anthuriums.

1 Increase local humidity immediately by using a pebble tray or a humidifier to prevent further leaf desiccation.
