Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often found with indoor Calla Lilies. They pierce the leaf cells of 'Captain Solo' to feed, leaving behind fine silken webbing as they create colonies on the undersides of leaves.

Very Common

How to confirm: Hold a white piece of paper underneath a leaf and tap the leaf firmly to see if tiny crawling specks fall onto the paper.

Tetranychus urticae (European Red Spider Mite)

While similar to the two-spotted variety, this mite is particularly aggressive in low-humidity environments. It causes the characteristic fine webbing and leads to stippling (tiny yellow dots) on the broad foliage of the Calla Lily.

Common

How to confirm: Inspect the undersides of the leaves for tiny reddish or orange moving dots near the web structures.

High Humidity/Stagnant Air Micro-colonies

In rare cases, extremely high humidity combined with lack of airflow can cause fungal hyphae to resemble fine webbing, though this is usually accompanied by leaf spotting. However, true spider mite webbing is much more structurally organized and 'silky' than fungal growth.

Common

How to confirm: Check if the 'webbing' feels structural/tough like silk or if it looks more like fuzzy, disorganized mold spores.

1 Increase airflow around the plant by using a small fan or moving it to a more ventilated area to disrupt micro-colony formation.

2 Monitor the plant closely for any signs of actual spider mites, such as organized silky webs or stippling on leaves; if found, treat with an organic insecticide.

3 Reduce humidity levels and ensure the soil surface is not staying excessively damp to prevent fungal growth.
