Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often experienced by Begonias, producing fine silk webbing to create a protective habitat for themselves. This webbing usually covers the undersides of leaves and can lead to stippling (tiny white dots) on the scarlet foliage.

Very Common

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

Low Humidity (Environmental Stress)

Begonia Havana Scarlet prefers higher humidity; extremely dry air can cause the plant's natural secretions or dust to clump, mimicking a web-like appearance. While not a true pest, low humidity weakens the plant's cuticle, making it more susceptible to actual mite attacks.

Common

How to confirm: Check if the fine webbing is accompanied by crispy, brown leaf edges or if the soil surface is extremely dry.

1 Increase ambient humidity around the plant to prevent the dry air from mimicking web-like patterns and to strengthen the plant's cuticle.

2 Inspect the undersides of leaves closely for actual spider mites, as low humidity makes the plant vulnerable to these pests.

3 Use a pebble tray or a humidifier to maintain a consistent moisture level in the air around your Begonia.

warning

Tetranychus urticae (European Red Spider Mite)

A specific variant of spider mite that is highly aggressive on Begonia cultivars. They create dense, heavy webbing that can eventually drape over the entire plant, significantly reducing the vibrant scarlet color of the leaves.

Common

How to confirm: Inspect the leaf undersides closely for small, reddish or orange moving dots within the webbing.

2 Wipe the leaves with a damp cloth to physically remove the dense webbing and any remaining spider mite eggs.

3 Increase local humidity around the Begonia, as spider mites thrive in dry conditions, and monitor soil moisture using a meter to prevent plant stress.
