Spider Mites (Tetranychidae)

The presence of fine, silk-like webbing is a hallmark symptom of spider mite infestations. These microscopic pests pierce the cell walls of Ficus microcarpa leaves to suck out nutrients, causing stippling and eventual leaf drop.

Very Common

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

2 Wipe the leaves thoroughly with a damp cloth to physically remove webbing and dislodge remaining pests.

Low Humidity/Desiccation

Ficus microcarpa is native to tropical environments; extremely dry indoor air can cause the plant to produce more silk-like strands or trap dust in a way that mimics webbing. This often coincides with physiological stress and leaf curling.

Common

How to confirm: Check if the ambient humidity is below 50% and observe if the leaves feel brittle rather than just dusty.

2 Gently wipe the leaves with a damp cloth to remove any dust or silk-like strands that may be mimicking spider mite webbing.

3 Monitor soil moisture levels closely to ensure the plant is not experiencing drought stress alongside low humidity.

Broad Mites

While broad mites do not produce visible webbing themselves, their feeding causes leaf distortion and puckering that can trap dust and debris, creating a web-like appearance on new growth.

Common

How to confirm: Inspect the youngest, most tender leaves for abnormal twisting, curling, or bronze discoloration.

1 Inspect the undersides of new leaves for distorted, puckered, or thickened growth and treat the plant with an organic insecticide to eliminate mites.

2 Prune away any heavily distorted or severely infested new growth to reduce the pest population and prevent further spread.

3 Increase humidity around the plant and ensure good airflow to make the environment less hospitable for mite-related debris buildup.
