Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often found with Anthuriums and create fine silk webbing to protect their colonies. They pierce plant cells to feed on sap, leading to stippling and chlorosis on the foliage.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap it sharply to see if tiny crawling specks or debris fall onto the paper.

Tetranychus urticae (European Red Spider Mite)

While similar to the two-spotted mite, this specific strain is highly aggressive on Anthurium species and can cause rapid webbing development across the entire plant canopy. This often occurs when humidity levels drop below 50%.

Common

How to confirm: Inspect the undersides of the leaves for tiny orange or reddish dots which indicate a heavy infestation.

2 Increase ambient humidity levels above 50% and use a fine mist spray to hydrate the foliage, as low humidity triggers mite aggression.

warning

High Humidity/Stagnant Air Mold

In some cases, very fine, wispy white structures can be mistaken for webbing but are actually fungal mycelium or mold strands. This occurs in Anthuriums when there is insufficient air circulation around the dense foliage.

Common

How to confirm: Check if the 'webbing' feels more like a fuzzy coating on the leaf surface rather than structural silk threads.

1 Increase air circulation around the foliage using a small fan to prevent stagnant air and inhibit mold growth.

2 Apply a fungicide to treat the fungal mycelium and protect the plant from further mold development.
