Check these first

  1. Look closely at the underside of the leaves for tiny insects.
  2. Check for a sticky residue on the foliage.
  3. Inspect the new growth at the tips of the stems.

Likely causes

  1. Aphids

    Most likely

    How to tell: You see small clusters of green or black insects on the undersides of leaves or near the stem tips. The leaves may also look sticky or distorted.

    What to do: Spray the plant with a gentle stream of water to knock the aphids off. Follow up by wiping the leaves with a mild solution of water and a few drops of dish soap every few days until they are gone.

  2. Low Humidity

    Possible

    How to tell: The plant looks stressed and attracts pests more easily in dry indoor air.

    What to do: Mist the leaves occasionally or place the plant on a pebble tray with water. This keeps the environment comfortable and less inviting to certain pests.

When to worry

If the infestation covers the entire plant and the leaves are curling or dying, you need to act fast. A few stray bugs are common and easy to manage with a quick wipe down.

Stopping it coming back

Check your plant weekly for any signs of insects. Keep the leaves clean by wiping them down with a damp cloth once a month.
