GREEN GUARDIA Cryptolaemus larvae – Australian ladybird larvae against mealybugs & scale insects
Australian ladybird larvae are the larval stage of Cryptolaemus montrouzieri, a beneficial organism that specifically tracks down and devours mealybugs and scale insects, including their egg clusters. They are a biological alternative to chemical sprays and are safe for children, pets, and plants.
Ladybird larvae against mealybugs: preventing the damage from returning
At first, it’s just one white dot in the leaf axil, then there are many. Mealybugs leave behind sticky honeydew, which later encourages the growth of sooty mold. Both suck plant sap and stunt growth. Wiping and rinsing with water gets rid of the insects you can see – but the egg clusters hidden in the crevices remain. Ladybird larvae against mealybugs tackle the problem at the root: they search through the hiding spots themselves.
Ladybird larvae against scale insects – windowsills, conservatories, greenhouses
Scale insects form white, cotton-like coatings on stems and leaves and love to hide in leaf axils. The location of the plant is key to success. Ladybird larvae (Cryptolaemus) need it warm: they work best between 20 and 30 °C. This makes houseplants, conservatories, and greenhouses typical environments, as well as ornamental and container plants and sensitive species like orchids, where sprays could cause damage. Ladybird larvae against scale insects are worthwhile wherever the temperature remains constant – but not in a cool outdoor environment.
How the larvae work
Once released, the larvae immediately begin foraging, crawling into leaf axils and crevices to eat mealybugs, scale insects, and their eggs. They leave no residues behind and are harmless to humans, children, and pets.
Buy Australian ladybird larvae: 25 larvae for up to 10 m²
One tube contains 25 larvae and is sufficient for about 10 m² of plant area in cases of light to moderate infestation; staggered options are available up to ten tubes for around 100 m². In cases of severe infestation, a second release after a few weeks is helpful. Delivered alive in a shipping tube from German breeding – it is best to release the larvae immediately upon receipt. If you would like to buy Australian ladybird larvae and need to cover a larger area, we also offer adult beetles and lacewing larvae.
When are Australian ladybird larvae the right choice?
Choose these larvae if you find white cottony patches or sticky honeydew on your houseplants, container plants, or orchids and want to take a biological approach instead of using chemicals. They are also the right choice if there are children or pets in the household and you do not want to spray sensitive plants. They are most effective at 20 to 30 °C.
When Australian ladybird larvae are not the right solution
Activity is limited below 18 °C, so they are not worth using in cool outdoor areas – the product is designed for interiors, conservatories, and greenhouses. The larvae are specialized for mealybugs and scale insects and will not help against other pests. And if you have used chemical pesticides, you must wait at least six weeks, otherwise the larvae will not survive.
🌿 Verdict: With Australian ladybird larvae from GREEN GUARDIA, you can tackle mealybugs and scale insects right where they hide – biologically, residue-free, and safe for children, pets, and plants.

Wie viele Larven brauche ich?
Wenn du Australische Marienkäferlarven kaufen willst, richtet sich die Menge nach der Fläche: Ein Röhrchen mit 25 Larven reicht bei leichtem bis mittlerem Befall für etwa 10 m². Wähle die Menge entsprechend deiner Pflanzenfläche.
Anwendung & Tipps: So nutzt du Australische Marienkäferlarven richtig
- Röhrchen öffnen: Das Versandröhrchen vorsichtig direkt am Einsatzort öffnen, nicht vorher.
- Larven ausbringen: Die Larven möglichst direkt an den befallenen Pflanzenteilen, in den Blattachseln oder nahe der Wolllausnester aussetzen.
- Wirken lassen: Die Larven suchen selbstständig nach Wollläusen und Schmierläusen und beginnen unmittelbar nach dem Aussetzen mit der Nahrungssuche.
- Temperatur: Optimal zwischen 20 und 30 °C. Deshalb vor allem für Innenräume, Wintergärten und Gewächshäuser geeignet.
- Direkt einsetzen: Die Larven nach Erhalt möglichst zeitnah ausbringen.
- Keine Chemie: Mindestens sechs Wochen vor und während des Einsatzes auf chemische Pflanzenschutzmittel verzichten.
- Bei starkem Befall: Eine zusätzliche Ausbringung nach einigen Wochen unterstützt die Ansiedlung.
- Vorbeugen: Pflanzen regelmäßig kontrollieren, besonders Blattunterseiten, Stängel und Triebspitzen. Bei den ersten Anzeichen früh Nützlinge einsetzen – und die Pflanzen stärken, denn gesunde Pflanzen sind widerstandsfähiger.
Geeignete Einsatzbereiche
- Zimmerpflanzen: Ideal bei Befall mit Wollläusen und Schmierläusen.
- Wintergärten & Gewächshäuser: Optimale Bedingungen für die Entwicklung der Larven.
- Zierpflanzen & Kübelpflanzen: Unterstützt die natürliche Regulierung von Wolllauspopulationen.
- Orchideen & empfindliche Pflanzen: Schonende Anwendung ohne chemische Rückstände.
- Innenräume & geschützte Bereiche: Besonders geeignet bei konstanten Temperaturen.
🐞 Tipp: Setze die Larven möglichst direkt an befallenen Pflanzenteilen aus. Dort finden sie Wollläuse besonders schnell und können unmittelbar mit ihrer natürlichen Nahrungssuche beginnen.
Blattläuse, Schmierläuse & Wollläuse natürlich regulieren – mit GREEN GUARDIA Cryptolaemus (Australischer Marienkäfer)
Blattläuse, Schmierläuse und Wollläuse zählen zu den häufigsten Pflanzenschädlingen an Zimmerpflanzen, Zierpflanzen sowie in Wintergärten und Gewächshäusern. Sie saugen Pflanzensäfte, schwächen das Wachstum und hinterlassen häufig klebrige Honigtau-Ausscheidungen auf Blättern und Stängeln.
Mit GREEN GUARDIA Cryptolaemus setzt du auf eine natürliche und chemiefreie Lösung. Der Australische Marienkäfer ernährt sich gezielt von Schmierläusen, Wollläusen und auch Blattläusen und hilft dabei, den Schädlingsbefall auf natürliche Weise zu regulieren.
Was macht diese Schädlinge so problematisch?
- Blattläuse: Vermehren sich sehr schnell und schwächen Pflanzen durch das Saugen von Pflanzensäften.
- Schmierläuse: Bilden weiße, watteartige Beläge an Stängeln und Blättern und verstecken sich oft in Blattachseln.
- Wollläuse: Hinterlassen klebrigen Honigtau, der häufig zu Rußtaupilzen auf Pflanzen führt.
So beugst du einem Befall vor
- Pflanzen regelmäßig kontrollieren: Besonders Blattunterseiten, Stängel und Triebspitzen prüfen.
- Frühzeitig handeln: Bei ersten Anzeichen von Befall schnell Nützlinge einsetzen.
- Pflanzen stärken: Gesunde Pflanzen sind widerstandsfähiger gegenüber Schädlingen.
- Natürliche Nützlinge einsetzen: Cryptolaemus-Marienkäfer helfen, Schädlingspopulationen auf natürliche Weise zu regulieren.
🐞 Tipp: Cryptolaemus arbeitet am effektivsten bei Temperaturen zwischen 20 °C und 30 °C. Bei stärkerem Befall kann eine zweite Ausbringung nach einigen Wochen sinnvoll sein.

Cryptolaemus montrouzieri, also known as the Australian ladybug, is a natural beneficial insect for controlling mealybugs, woolly aphids, and aphids. Both the adult beetles and their larvae feed on these pests, helping to reduce the infestation in a natural way.
A tube with 10 adult Cryptolaemus ladybugs or 25 Cryptolaemus larvae is suitable for a plant area of up to 10 m², depending on the severity of the infestation. In cases of heavier infestation or high pest density, an additional application may be advisable.
Cryptolaemus feeds mainly on mealybugs and woolly aphids. Additionally, it also eats aphids, making it versatile for use against various types of lice.
Under good conditions, the beetles can reproduce. The larvae that hatch from the eggs also consume large quantities of mealybugs and woolly aphids.
Use is particularly suitable for houseplants, conservatories, greenhouses, and protected outdoor areas.
The beneficial insects are delivered alive and securely in a ventilated shipping tube. You can choose between tubes with 10 adult Cryptolaemus ladybugs or 25 Cryptolaemus larvae. After release, the beneficial insects begin to search for suitable food sources on their own and are suitable for plant areas of up to 10 m², depending on the severity of the infestation.
The beneficial insects should be released as soon as possible after receipt so they can quickly start searching for pests.
If necessary, the beetles can be stored in a cool, shady place for 1–2 days. Ideally, however, they should be used quickly.
Yes, they are shipped in special tubes that provide sufficient air and protection during transit. We also ship the ladybugs via Express Registered Mail.
The animals are usually quieter during transit but will quickly become active again after release.
Open the box carefully right by the infested plants and release the beetles as close as possible to the affected plant parts.
Cryptolaemus works most effectively at temperatures between 20 °C and 30 °C.
The beetles stay where they find food. If there are enough pests, they usually stay in the plant area for a longer period of time.
Yes, they can be well combined with other biological beneficial insects. It is important, however, not to use chemical plant protection products.
No, it is best to release them directly on the infested plants so they can find the pests quickly.
Yes, the ladybugs are completely harmless to humans, pets, and plants.
The beetles often hide between leaves or in leaf axils, where the mealybugs are located.
The ladybugs start searching for food immediately after release. A visible reduction in infestation can occur after about 2–3 weeks, depending on the severity.
Yes, adult Cryptolaemus ladybugs can fly. If there is sufficient food supply, however, they predominantly stay in the area of the infested plants. The larvae are not capable of flight and remain directly on the plant, where they actively search for suitable food sources.
In case of very heavy infestation, an additional release after a few weeks may be advisable.
