Visible pests or webbing

Direct pest clues deserve close inspection.

Visible insects, webbing, or sticky residue are reasons to inspect closely. Identify what you see before choosing a treatment, and keep the plant separate while you check it.

Quick visible pests or webbing guide

Check first

  • Inspect leaf undersides, new growth, stem joints, pot rims, and saucers in good light; a magnifier can help with very small pests.
  • Look for direct clues such as fine webbing, stippling, cottony deposits, raised bumps, eggs, or shiny sticky residue.
  • Separate the plant from nearby plants while you identify the pest and check neighbouring plants for the same signs.

Common causes

  • Possible pest pressure

Good to know

  • Webbing, sticky residue, and raised bumps are different clues.
  • Pest identification matters before choosing a treatment.
  • Nearby plants may show earlier or clearer evidence.

What to do next

  1. Move the plant away from nearby plants while inspecting it.
  2. Photograph or identify the visible pest as precisely as possible.
  3. Check leaf undersides, stem joints, and nearby plants.
  4. Use only an indoor-plant treatment labelled for the identified pest.

When to act fast

  • Fine webbing with stippling or bronzing, or a rapidly increasing number of insects, calls for prompt identification and appropriate action rather than a general-purpose treatment guess.
  • A plant with pests plus severe leaf drop, distorted new growth, or major loss of vigour may need more than a surface rinse; follow product labels and seek local advice if the issue persists.

Common questions

Frequently asked questions

Does webbing on a houseplant always mean spider mites?

Webbing is an important clue, but inspect it closely with other signs such as stippling or tiny moving pests before deciding what it is.

Why should I separate a plant with visible pests?

Isolation makes inspection easier and helps limit contact with nearby plants while you identify the pest and choose an appropriate response.

Can I use any insect spray indoors?

No. Use only a product labelled for the plant and indoor setting, identify the pest first where possible, and follow every label direction.
