Two-Spotted Spider Mites (Tetranychus urticae)

These tiny arachnids thrive in the warm, dry conditions that Hosta plantaginea often encounters during summer. They pierce individual cells of the host leaves to suck out contents, leaving behind fine silk webbing and stippling patterns.

Very Common

Spider Mites (General)

While Two-Spotted are most common, other mite species can inhabit the underside of Hosta foliage. The webbing is a defensive structure used to protect their eggs and create a microenvironment for colonies.

Very Common

How to confirm: Look for tiny yellow or white dots (stippling) on the surface of the hosta leaves near the webbing.

2 Physically remove visible webbing and mites by rinsing the foliage with a strong stream of water to disrupt their microenvironment.

3 Monitor the plant regularly using a magnifying glass to catch any new infestations before they spread.

warning

Small Slug/Snail Trails and Silk

Certain gastropods may leave behind mucus trails that can appear as thin, silvery lines or web-like structures across the broad leaves of the Hosta. While not true 'webbing,' it is often confused with mite activity in damp shaded areas.

Common

How to confirm: Check for shiny, dried slime trails on the leaf surface or near the base of the hosta plant.

1 Inspect the undersides of leaves and the soil surface for slugs or snails, and remove any visible pests manually during damp evening hours.
