Check these first
- Inspect the undersides of leaves with a magnifying glass.

- Check for webbing between leaf joints.
Likely causes
Spider Mites
Most likelyHow to tell: You see fine, silky webbing between the leaves and tiny yellow stippling on the foliage. The leaves may eventually look dusty or bleached.
What to do: Wipe the leaves down with a damp cloth to remove the webs. Spray the plant with insecticidal soap every 5 days for 2 weeks to kill any remaining mites.
Aphids
PossibleHow to tell: Small green or black insects cluster on the new growth and flower buds. They leave behind a sticky substance called honeydew that can attract ants.
What to do: Blast the insects off with a gentle stream of water from a spray bottle. If they persist, apply neem oil to the affected areas once a week.

When to worry
A few stray insects are easy to manage, but a full infestation that covers the stems requires immediate treatment. It is normal to see an occasional bug outdoors, but indoor plants should be kept pest free.
Stopping it coming back
Keep the plant in a well ventilated area and wipe the leaves with a damp cloth monthly to discourage pests.
