Cryptolaemus montrouzieri

Type

Predator (mealybug destroyer)

Target pests

• Mealybug

Notes

Key predator for ornamental crops with persistent mealybug problems.

Best deployment strategy

• Use as a targeted clean-up predator where mealybug colonies are present.
• Place directly onto infested plants/areas; follow up with repeat introductions if colonies persist.
• Combine with parasitoids or cultural controls to prevent re-infestation.

Compatibility notes

• Works well with: spot treatments and sanitation to remove heavily infested plant material.
• Note: predators may disperse if prey is scarce; follow-up introductions may be needed.

Environmental preferences

• Typically performs best in warmer conditions with established mealybug colonies.
• Can be slow or ineffective in cool environments.
