Mealybugs look like small blobs of white cotton tucked into leaf joints, stem crevices and leaf undersides. They’re common on hibiscus, ornamentals and many indoor plants, and their waxy coat makes them stubborn — which is where neem oil’s repeat action pays off.
Why mealybugs are tricky
That waxy, cottony coating repels many sprays and protects eggs. Neem works by disrupting the insects that feed and by coating and smothering the colony over repeated applications.
How to apply
- For small outbreaks, dab visible clusters with a cotton bud first.
- Spray water-soluble neem oil thoroughly into every crevice and leaf joint. See the dilution chart.
- Repeat every 5–7 days for several cycles to catch newly hatched crawlers.
- Check nearby plants — mealybugs spread easily.
Will neem oil kill mealybug eggs?
It smothers eggs and crawlers over repeated sprays; persistence is key.
Is neem safe for indoor plants with mealybugs?
Yes, and it’s one of the best indoor options — low odour and no toxic residue.
