Two-Spotted Spider Mite (Tetranychus urticae)

These microscopic arachnids thrive in the warm, dry conditions often experienced by Viola cornuta. They pierce the leaf cells to feed on sap, leaving behind characteristic fine silken webbing and stippling.

Very Common

1 Immediately spray the plant with an organic miticide to eliminate existing spider mites and their eggs.
2 Increase humidity around the plant and wipe leaves with a damp cloth to physically remove webbing and disrupt the mites' dry habitat.
3 Monitor soil moisture levels to ensure the environment does not become too dry, which encourages mite outbreaks.

Tetranychid Mite Infestation (Bladder Mites)

In high humidity or specific microclimates, other species of mite may produce webbing that appears as a fine mesh across the violets' foliage.

1 Apply an organic miticide/insecticide spray to the foliage to eliminate the mites and their eggs.
2 Gently wipe the leaves with a damp cloth to physically remove the fine webbing and any remaining mites.
3 Monitor soil moisture levels to ensure the environment does not become overly humid, which can favor certain mite species.
warning

Thrips Infestation

While thrips do not produce webbing themselves, heavy infestations can cause leaf scarring and silken debris from their movement and feeding damage that may be mistaken for fine webs.

Common
