How to Get Rid of Mealybugs
Last Updated: May 2026 · Plant Care Answer
Direct Answer
To get rid of mealybugs, isolate the plant, remove visible cottony clusters with a cotton swab dipped in 70% isopropyl alcohol, rinse or wipe foliage, then repeat treatment weekly. Heavy infestations may need insecticidal soap or a labeled houseplant spray.
How to Identify Mealybugs
- ->White cottony clusters in leaf joints, stems, or undersides.
- ->Sticky honeydew on leaves or nearby surfaces.
- ->Yellowing leaves, weak growth, or distorted new growth.
- ->Ants may appear if plants are outdoors or near entry points because they feed on honeydew.
Treatment Plan
- ->Move the plant away from the rest of your collection.
- ->Dab visible bugs with 70% isopropyl alcohol, testing a small area first on sensitive leaves.
- ->Prune heavily infested stems if the plant can handle it.
- ->Wash the plant and pot rim; mealybugs hide in crevices.
- ->Repeat weekly for at least 3-4 weeks because eggs and crawlers are easy to miss.
When to Give Up
Mealybugs are persistent. If an inexpensive plant is heavily infested and sits near rare or valuable plants, discarding it can be the most practical way to protect the rest of the collection.
