Likely causes
Spider Mites
Most likelyHow to tell: You will see fine webbing between leaf stems and tiny yellow stippling on the leaf surface. Look closely at the underside of the leaves for tiny moving specks.
What to do: Wipe the leaves down with a damp cloth to remove the mites. Spray the entire plant with neem oil or insecticidal soap every 5 to 7 days until the pests are gone.
Low Humidity
PossibleHow to tell: The plant looks stressed and the air in your home feels very dry. Mites thrive in these conditions.
What to do: Increase humidity by grouping plants together or using a humidifier. Mist the leaves occasionally to discourage mites from settling in.

When to worry
If the webbing covers the entire plant and leaves are turning yellow, the infestation is severe. A few mites are manageable, but do not wait to treat them.
Stopping it coming back
Keep your plant healthy with consistent watering and wipe the leaves with a damp cloth once a month to remove dust and potential pests.
