Cryptolaemus montrouzieri - FAQs

Are Mealybug Destroyers effective?
Yes. Because both the adult and larval stages actively hunt mealybugs, a single release targets the pest at multiple points in its life cycle, which is part of why this species is widely used for mealybug-specific outbreaks.

Do Mealybug Destroyers eat aphids?
They can feed on aphids and soft scale opportunistically when mealybugs aren't available, though mealybugs remain their primary target and preferred food source.

Can I release Mealybug Destroyers indoors?
Yes. Indoor releases work well on houseplants as long as temperatures stay within the 60–95°F range and the area isn't disrupted by strong drafts right after release.

What's the difference between a Mealybug Destroyer larva and an actual mealybug?
Both have a white, waxy, cottony appearance, which is exactly what makes them easy to mix up. Mealybug Destroyer larvae are more mobile and elongated, while mealybugs stay clustered and largely stationary in one spot.

Do ants affect how well Mealybug Destroyers work?
Yes. Ants often protect mealybug colonies in exchange for the honeydew mealybugs produce, which can interfere with predation. Managing ant activity alongside your release improves results.
