Spider Mites (Tetranychidae)

The presence of fine, silken webbing is a classic diagnostic sign of spider mites, which thrive in the warm, low-humidity environments often provided to Dracaena sanderiana. These pests pierce plant cells to suck out sap, leading to stippling and eventual yellowing of the leaves.

Two-Spotted Spider Mites

A specific subspecies of spider mite that is particularly aggressive on indoor tropicals like Lucky Bamboo when air circulation is poor. They create dense webs around the leaf junctions and stem nodes to protect their eggs.

High Humidity/Mold Growth

While rare to see 'webbing' from mold, certain fungal hyphae can appear as fine, white, hair-like structures in extremely stagnant, high-humidity environments. This is usually accompanied by a musty smell and dark spotting on the leaves.

Common

How to confirm: Check if the 'webbing' feels fuzzy or organic rather than silken and if there is an odor of decay.
