When to worry
A few pests are manageable, but if the entire plant is covered or the leaves are wilting, you need to act fast. Severe infestations can weaken the plant significantly.
Stopping it coming back
Inspect your plant every time you water it. Keep the foliage clean and avoid overcrowding to improve airflow.

Questions people ask
- Will these pests kill my plant?
- They can weaken the plant over time by sucking out sap. If left untreated, the plant may lose vigor and become susceptible to other diseases.
- Can I use dish soap to kill them?
- A mild solution of water and a few drops of dish soap can help, but be sure to rinse the leaves afterward. Horticultural oil is usually more effective for scale.
