mealybugs on Hoya Finlaysonii P
Quick answer
If your Hoya Finlaysonii P has mealybugs, the most likely cause is: Hoyas, including Hoya carnosa and its relatives such as Hoya finlaysonii with their thick leathery succulent leaves and vining habit, are explicitly listed by houseplant authorities as prone to mealybug infestation, where the insects gather as cottony wads on stems, leaves, and at the nodes of the vine.
Start here:
- 1. Physically remove as many mealybugs as possible with a soft toothbrush, then dab any remaining insects with a cotton swab drenched in isopropyl alcohol so the alcohol dehydrates the bugs on contact; repeat the applications until no more pests show up.
- 2. Follow up with insecticidal soap, All Seasons Horticultural Oil, or Neem sprayed on stems and the undersides of leaves, and if root mealybugs are suspected, remove the plant from its pot, soak the rootball in insecticidal soap for a few hours, and repot into a clean pot with fresh potting material.

Keep mealybugs off this Hoya Finlaysonii P
Inspect new Hoya plants carefully before introducing them and isolate them from the rest of the collection for several weeks, keep the vine well-spaced so air circulates around the leathery leaves, and check leaf axils and stem nodes regularly because the early cottony masses are easiest to remove before the population builds.
