mealybugs on Philodendron
Quick answer
If your Philodendron has mealybugs, the most likely cause is: Mealybugs (Pseudococcidae) can infest both the foliage (white cottony clusters in axils) and the root zone (root mealybugs). Philodendrons' fibrous, moisture-retentive roots and large leaf nodes provide ideal hiding spots. Soil-borne infestations often present as systemic decline or yellowing without visible leaf pests.
Start here:
- 1. For leaf mealybugs: dab individuals with 70% isopropyl alcohol on a cotton swab.
- 2. For root mealybugs: remove the plant from the pot, discard all soil, and rinse roots thoroughly in 120°F (49°C) water or a 1:4 hydrogen peroxide solution.
