- Check the new growth tips for clusters of small insects.
Likely causes
Whitefly
Most likelyHow to tell: You will see tiny white moth like insects flying up when you disturb the plant. They leave behind a sticky residue called honeydew on the leaves.
What to do: Spray the entire plant with insecticidal soap every 5 to 7 days. Make sure to coat the undersides of every leaf thoroughly. Repeat this for at least 3 weeks to catch new eggs hatching.
Aphids
Most likelyHow to tell: These are small green or black insects that cluster on new growth and flower buds. They cause leaves to curl and stunt the overall growth of the plant.
What to do: Wash the plant off with a strong stream of water in the shower or sink. Follow up with a neem oil spray applied once a week until the insects are gone. Keep the plant away from other houseplants while you treat it.

When to worry
If the leaves are turning yellow and dropping rapidly, the infestation is severe. Small numbers are manageable, but do not wait to treat them.
Stopping it coming back
Keep your plant healthy with consistent watering and good airflow. Regularly wipe down leaves with a damp cloth to remove dust and potential hitchhikers.
