Check these first

  1. Inspect the undersides of the leaves for tiny moving insects.
  2. Look for fine webbing between the stems or leaves.
  3. Check for sticky residue on the leaves or the surface below the plant.

Likely causes

  1. Aphids

    Most likely

    How to tell: Small green or black insects cluster on the new growth and undersides of leaves. You might also see a sticky residue called honeydew.

    What to do: Wipe the leaves with a damp cloth or spray them with a gentle stream of water. For larger infestations, use insecticidal soap once a week until they are gone.

  2. Spider Mites

    Possible

    How to tell: Fine webbing appears between leaves or stems, and the foliage looks stippled or pale. These pests thrive in dry, warm conditions.

    What to do: Increase the humidity around the plant to discourage mites. Wipe the leaves down with neem oil or insecticidal soap every 7 days.

When to worry

It is normal to see an occasional stray bug, but an infestation that covers the plant requires immediate action. Worry if the plant shows signs of stunted growth or yellowing.

Stopping it coming back

Keep the plant healthy with proper light and moisture, and ensure good air circulation to prevent pest buildup.

Questions people ask

Can I use household soap to kill the bugs?

How do I stop pests from coming back?
