GREEN GUARDIA Cryptolaemus – Australian ladybirds against mealybugs, scale insects & aphids

Mealybugs, scale insects and aphids can significantly weaken plants and often leave behind sticky honeydew secretions as well as typical white deposits on leaves, shoots, and stems. The Australian ladybird (Cryptolaemus montrouzieri) is a natural beneficial insect that specifically tracks down these pests and uses them as a food source.

Both the larvae and the adult beetles feed primarily on mealybugs and scale insects. Aphids can also occasionally serve as an additional food source. This makes Cryptolaemus ideal for naturally supporting the biological balance of your plants – without the need for any chemical agents.

Suitable areas of application

  • Houseplants: Especially suitable for infestations of mealybugs, scale insects, or aphids.
  • Conservatories & greenhouses: Ideal conditions for using these beneficial ladybirds.
  • Ornamental plants & potted plants: Supports the natural regulation of pest populations.
  • Orchids & sensitive plants: A gentle method without chemical residues.
  • Indoors & protected areas: Particularly suitable for constant temperatures.

How to use

  1. Open the tube: Carefully open the shipping tube directly at the site of application.
  2. Release the beneficials: Carefully place the beetles near the infested plant or position the open tube in the immediate vicinity.
  3. Let nature take its course: The beneficial insects will actively search for mealybugs, scale insects, and other suitable food sources and will begin their search independently after release.

Important notes

  • Temperature: Optimal at temperatures between 20 °C and 30 °C.
  • No chemicals: Do not use chemical pesticides before or after release.
  • Use immediately: Release the beneficial insects as soon as possible after receipt.
  • Delivered in a tube: The ladybirds are delivered securely in a shipping tube.
  • In case of severe infestation: An additional release may be useful.

🐞 Tip: Release the ladybirds as close as possible to the infested parts of the plant – this allows them to find mealybugs and scale insects particularly quickly.

FAQ's

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.
