Plant problems

Spider mites on plants

Mites thrive in warm dry conditions and are easiest to confirm on leaf undersides and young growth.

Warm dry air

Heated rooms can support rapid population growth.

Hidden spread

Mites move between touching plants.

Delayed detection

Early stippling is easy to mistake for dust or stress.

Problem

What to do next

  1. 1

    Isolate the affected plant and inspect nearby plants.

  2. 2

    Rinse or wipe foliage where the species tolerates it.

  3. 3

    Use only a suitable labelled treatment and repeat checks according to its instructions.

Observation

When to act sooner

  • Webbing covers growing points.
  • Several plants are affected.
  • Leaves bronze and fall rapidly.
Important

Spider mites on plants can have several causes. Confirm the plant, conditions and recent care before choosing a treatment.
