Likely causes
Mealybugs
Most likelyHow to tell: You see small, white, cottony masses in the leaf axils or under the leaves. The plant may look sticky or have stunted growth.
What to do: Dip a cotton swab in rubbing alcohol and touch it directly to the bugs to kill them on contact. Repeat this every few days until you see no more pests.
Scale
PossibleHow to tell: Small, hard brown bumps appear on the stems or leaves that look like tiny shields. They do not move and are hard to scrape off.
What to do: Gently scrape the bumps off with your fingernail or a soft brush dipped in soapy water. Wipe the leaves down with a damp cloth to remove any sticky residue.

When to worry
If you see a heavy infestation covering the whole plant, it is serious and requires immediate treatment. A few isolated bugs are easy to manage with regular checks.
Stopping it coming back
Inspect your plant every time you water it. Keep new plants away from your Hoya for two weeks to ensure they do not bring pests into your home.
