Fine spider-mite webbing on the underside of a leaf

Problems

Spider Mites

Tiny sap-sucking mites that leave fine webbing on foliage.

Symptoms

  • Fine webbing on new growth or the undersides of leaves
  • Yellow speckling or stippling on leaves
  • Leaves fading, drying, and dropping
  • Tiny moving dots visible with a hand lens

Causes

  • Warm, dry indoor air
  • Bringing in an infested new plant
  • Dusty leaves that don't get cleaned
  • Poor airflow

Treatment

  1. 01Isolate the plant immediately — spider mites spread fast.
  2. 02Take the plant to a shower or sink and rinse both sides of every leaf.
  3. 03Spray thoroughly with insecticidal soap, neem oil, or a mix of water and mild dish soap.
  4. 04Repeat every 4–5 days for at least 3 weeks to catch newly hatched mites.
  5. 05Boost humidity — mites hate damp air.

Prevention

  • Keep humidity above 50%.
  • Wipe leaves monthly and inspect the undersides.
  • Quarantine new plants for two weeks.
  • Never let dust build up on foliage.
