- Isolate the plant from your other houseplants immediately.
Likely causes
Mealybug infestation
Most likelyHow to tell: You will see white, fluffy masses that look like tiny bits of cotton tucked into stem nodes. The plant may also develop sticky honeydew on the leaves.
What to do: Dab the bugs with a cotton swab dipped in rubbing alcohol to kill them on contact. Follow up by spraying the entire plant with neem oil or insecticidal soap once a week for 3 weeks.
Scale insects
PossibleHow to tell: These appear as small, hard, brown bumps on the stems that do not move. They act like armor and protect the insect underneath.
What to do: Gently scrape the bumps off with your fingernail or a soft toothbrush. Wipe the stems down with a cloth soaked in diluted dish soap to remove any remaining larvae.

When to worry
If the infestation covers the entire plant and the stems are turning black, the plant is in serious trouble. A few spots are easy to manage if caught early.
Stopping it coming back
Wipe down your plant leaves with a damp cloth every month to remove dust and check for hitchhikers. Keep new plants away from your Hoya for 2 weeks to ensure they are pest free.

Questions people ask
- Can I just wash the bugs off with water?
- Water alone will not kill mealybugs because they are protected by a waxy coating. You must use alcohol or insecticidal soap to break through that barrier.
- Will these bugs spread to my other plants?
- Yes, mealybugs can crawl or be carried by air currents to nearby plants. Keep your infected Hoya in a separate room until you are sure the pests are gone.
