Two-Spotted Spider Mite Infestation

The presence of fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often found around Anthuriums. These pests pierce plant cells to suck out sap, causing stippling and eventual leaf drop.

Very Common

Low Humidity / Desiccation

While not directly causing webbing, extremely low humidity can stress Anthurium andraeanum, making them more susceptible to mite outbreaks. Dry air causes the leaf edges to crisp and creates an environment where silk-spinning pests thrive.

How to confirm: Check if the air temperature is high and use a hygrometer to see if humidity levels are below 50%.

Broad Mites (Eriophyid Mites)

Unlike spider mites, broad mites are microscopic and do not produce large webs, but their presence can lead to secondary webbing from other opportunistic pests. They cause characteristic distorted, stunted, or 'blistered' new growth on the Anthurium leaves.

Common

How to confirm: Inspect the newest, most tender leaves for puckering, curling, or abnormal growth patterns.
