Parasitic wasps against codling moths
Naturally effective – without chemicals: Our GREEN GUARDIA parasitic wasps are highly effective, biological beneficial insects for the targeted control of codling moths (Cydia pomonella) and other moth species – ideal for use in orchards, on apple trees, plums and pears .
What are parasitic wasps?
Trichogramma parasitic wasps are tiny insects, measuring only 0.3–0.4 mm, that specifically parasitize pest eggs . They are completely harmless – they don't sting, don't fly , and leave no residue . Their sole purpose: to detect and destroy codling moth eggs .
How do parasitic wasps work in the orchard?
- The parasitic wasps hatch from carrier cards that you hang directly in the tree.
- They actively search for leafroller eggs on leaves, twigs and fruits .
- The eggs are parasitized – no new larvae can hatch.
- Once their work is done , the beneficial organisms disintegrate without leaving any residue .
Application & placement in the garden
Place the carrier cards directly into the fruit trees early during the egg-laying period (from approximately mid-May). We recommend one card per tree or every 2–3 meters in the stand, depending on the size and density of the planting.
Which crops is it suitable for?
- Apple trees (against codling moth)
- Plum and damson trees (against plum moth)
- Pears & other stone fruits
🌿 Tip: For optimal effect, the application should be carried out several times at intervals of 2-3 weeks in order to cover the entire egg-laying phase.
Einzellieferung zur Apfelwickler-Bekämpfung – wann sinnvoll?
Die Einzellieferung unserer GREEN GUARDIA Schlupfwespen eignet sich ideal als ergänzende Maßnahme zur Verlängerung einer bereits durchgeführten Schlupfwespenbehandlung – besonders dann, wenn noch einzelne Apfelwickleraktivität beobachtet wird.
Wichtig: Die Einzellieferung ersetzt keine vollständige Kur! Eine alleinige Anwendung ist nicht ausreichend, um den Apfelwickler dauerhaft zu bekämpfen.
Warum eine 9‑Wochen‑Kur mit 3 Lieferungen?
Unsere GREEN GUARDIA 9-Wochen-Kur mit Schlupfwespen wurde entwickelt, um den kompletten Entwicklungszyklus des Apfelwicklers zuverlässig zu unterbrechen.
Der Apfelwickler durchläuft mehrere Stadien – vom Ei zur Larve, Puppe und schließlich zum erwachsenen Falter. Um alle Generationen zu erfassen, erfolgt die Anwendung in drei aufeinander abgestimmten Lieferintervallen.
Ablauf der Kur:
- 1. Lieferung (1–3 Tage nach Bestellung): Parasitiert vorhandene Apfelwicklereier.
- 2. Lieferung (nach 3 Wochen): Bekämpft neu abgelegte Eier durch die nächste Faltergeneration.
- 3. Lieferung (nach 6 Wochen): Finaler Schutz zur nachhaltigen Reduzierung des Apfelwicklers.
Dein Vorteil:
- Nur 1x bezahlen – du erhältst automatisch 3 zeitlich abgestimmte Lieferungen.
- Kein Abo, keine versteckten Kosten.
- Optimale Langzeitwirkung gegen Apfelwickler in Hausgärten und im Obstbau.
🍏 Tipp: Starte die Behandlung frühzeitig im Jahr (ab Mai), um der ersten Eiablage zuvorzukommen. So schützt du deine Ernte von Anfang an – ganz ohne Chemie.
Was sind Apfelwickler?
Apfelwickler (Cydia pomonella) zählen zu den häufigsten und hartnäckigsten Schädlingen im Obstbau – insbesondere an Äpfeln, Birnen und Pflaumen. Die unscheinbaren Falter legen ihre Eier direkt auf Blätter und junge Früchte ab.
Nach dem Schlüpfen fressen sich die Larven ins Fruchtinnere und hinterlassen Bohrlöcher, braune Fraßgänge und Kotkrümel. Oft wird der Befall erst spät erkannt – wenn die Frucht bereits beschädigt ist oder vorzeitig abfällt.
Wie kann ich Apfelwicklerbefall vorbeugen?
- Frühzeitige Ausbringung von Schlupfwespen zur Unterbrechung des Entwicklungszyklus
- Befallene Früchte frühzeitig entfernen und entsorgen – nicht auf dem Kompost!
- Klebefallen oder Pheromonfallen zur Überwachung der Flugzeit verwenden
- Baumumgebung sauber halten, z. B. Fallobst regelmäßig aufsammeln
🐛 Tipp: Auch nach der Ernte lohnt sich eine Schlupfwespen-Nachbehandlung, um überwinternde Eier zu bekämpfen und den Druck im nächsten Jahr zu minimieren.

FAQ parasitic wasps
Do you have questions about our products, their use, or shipping? Here you'll find the most important answers at a glance. If anything remains unclear, please feel free to contact us!

Ichneumon wasps are tiny insects that parasitize pest eggs. They lay their eggs inside the pest eggs, destroying them and stopping the pests from reproducing.
Yes, parasitic wasps are harmless to humans and pets. They don't sting and don't contain any toxins.
A "trigram" card is a carrier material on which the eggs of parasitic wasps are attached. These cards are used to control pest infestations.
The parasitic wasps begin attacking the pest eggs within a few days of laying out the cards. The entire process can take several weeks.
When there are no more pest eggs, the parasitic wasps die on their own.
Depending on the type of pest, a pest infestation can be identified by various typical signs:
- in storage containers, shelves or wardrobes
- on fruit, wood, leaves or fruits
- near food, plants or light sources
- for house or garden plants
- in textiles, soil or plants
The earlier you detect the infestation, the more effectively you can counteract it with natural remedies – such as our beneficial insects.
The cards will be securely packaged and sent by mail. Delivery in Germany is handled by Deutsche Post. Please check your mailbox regularly.
Yes, the parasitic wasps are packaged in such a way that they can survive even in cold temperatures.
Subsequent deliveries are made automatically, so tracking is often not available. If you have any questions, please feel free to contact us at any time.
Live beneficial insects are non-returnable. However, we're happy to help you with any problems.

To use the parasitic wasps effectively against codling moths, you should place the carrier cards in a targeted manner and early in the garden or orchard:
- Start in May, as soon as temperatures are consistently above 15 °C – this is the main egg-laying period for codling moths.
- Hang the cards directly in the apple, pear or plum trees – preferably near young fruit or branches.
- Use approximately 1 card per tree or every 2–3 meters in the tree row, depending on the size and density of the area.
- Repeat the application at least three times at intervals of 2–3 weeks to capture all egg generations.
The parasitic wasps actively search for codling moth eggs, parasitize them and thus prevent new larvae from hatching – without any chemicals.
No, the cards don't need to be opened. Simply lay them out as they were delivered.
Treatment typically takes several weeks. The cards should be replaced every three weeks until the infestation is completely eliminated.
Lay out the cards immediately upon receipt and avoid using chemicals near the cards.
Please refer to the respective product descriptions. There we explain how many cards you need.
Ichneumon wasps only move short distances, so it's important to place the cards in close proximity to the infestation.
Yes, pheromone sticky traps can be used in parallel to catch adult pests.
Yes, it's possible for the parasitic wasps to be dormant in the packaging. Lay out the cards as instructed to allow them to hatch.
The treatment lasts several weeks, as the parasitic wasps must continuously parasitize new pest eggs. A shorter application is often not sufficient to completely eliminate the infestation.
Parasitic wasps only attack codling moth eggs , not hatched larvae or damage from feeding . If the larvae are already inside the fruit, they eat through the flesh and render the apples inedible.
To prevent the pests from developing further or laying eggs again, it's important to consistently remove and dispose of infested fruit – not in the compost , but in the general waste. This effectively interrupts the life cycle and prevents the codling moth from spreading further – even in the next season.
Moth species—such as the codling moth and plum moth —prefer to attack ripening fruit directly on the tree. Particularly at risk are:
- Apples
- pears
- Plums and damsons
- Apricots
- Quinces
The larvae bore into the fruit flesh, leaving brown feeding tunnels , holes , and crumbly droppings . Infected fruit often falls prematurely from the tree.
You should consistently collect these fruits from the ground and dispose of them in the household waste —not in the compost! This interrupts the development cycle and effectively prevents a more severe infestation next season.
Common types of moths in households are food moths and clothes moths.
