Two-Spotted Spider Mite (Tetranychus urticae)

These microscopic arachnids thrive in the warm, dry conditions often experienced by Lilium bulbiferum during summer. They pierce cell walls to suck sap, leaving behind fine silk webbing as they create protective colonies on the undersides of leaves.

Very Common

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

1 Apply an organic miticide or insecticide spray to the plant, ensuring you thoroughly coat the undersides of the leaves where the mites reside.
2 Increase local humidity and reduce dry heat by misting the foliage regularly to create an environment less hospitable to spider mites.
3 Gently wipe the leaves with a damp cloth to physically remove webbing and any remaining mite colonies.

Thrips Infestation

While thrips are more known for silvery scarring on lily petals and leaves, high-density populations can occasionally produce silk-like strands or debris that mimic fine webbing during their movement through foliage.

Common

How to confirm: Check the flower buds and leaf crevices for small, slender, dark-colored insects moving rapidly.

1 Apply an organic insecticide spray to the foliage to eliminate existing thrips and prevent further damage to the lily petals.
2 Place yellow sticky traps near the plant to capture adult thrips and monitor the population density.
3 Inspect the undersides of leaves and remove any heavily infested or damaged foliage to reduce the pest's breeding grounds.

Southern Yellow Stock Spider Mite (Phytoseiulus persimilis) infestation/Uncontrolled pest population

While predatory mites are beneficial, a sudden presence of fine webbing in lilies often indicates an explosion of prey species that has overwhelmed the natural predators in your garden.

Common

How to confirm: Inspect the leaf undersides for much larger, slower-moving orange mites which indicate a biological control attempt is underway.

1 Apply an organic insecticide spray to eliminate the spider mite population and break the life cycle of the pests.
2 Increase humidity around the lily foliage by using a fine mist spray to create an environment less favorable to spider mites.
3 Carefully prune and dispose of heavily infested or webbed leaves to prevent the mites from spreading to healthy parts of the plant.
