GREEN GUARDIA nematodes against ants
Natural and targeted action against ants in the garden: GREEN GUARDIA nematodes are microscopic threadworms that detect ant larvae in the soil and biodegrade them – completely without chemicals, without residues and harmless to humans, pets and beneficial insects.
The nematodes are simply applied with water and thus reach the ant nests directly. There, they interrupt the ant's development cycle, weaken the colony, and lead to a sustainable reduction in infestation – ecologically and effectively.
Areas of application for nematodes against ants
- Terraces, paths & paving joints: Ideal for targeted treatment of nests in cracks and crevices.
- Garden beds & lawns: Nematodes penetrate deep into the soil and reach the ant nests.
- Raised beds & planters: Safe for edible plants and young seedlings.
- Compost heaps and cracks in walls: where ants often settle undisturbed.
- Living area: Natural protection without toxins near children or pets.
Application & Tips
- Application: Mix nematodes with water and pour directly into the nest openings or onto infested areas.
- Soil temperature: Optimal between 10–28°C – do not apply in frost or direct heat.
- Moisture: Keep soil moist before and after application – nematodes need water to survive and move.
- Repetition: In case of heavy ant infestation, treat again after 7–14 days.
- No pesticides: Avoid chemicals – they can impair the effectiveness of the nematodes.
- Storage: Store in a cool place (4–8 °C) for a maximum of 1 week – ideally applied immediately after receipt.
🌿 Conclusion: With GREEN GUARDIA nematodes you can declare war on ants – environmentally friendly, effective and without risk to children, animals or your garden plants.
Ameisen natürlich bekämpfen – mit GREEN GUARDIA Nematoden
Ameisen im Garten, Hochbeet oder Gewächshaus sind nicht nur lästig – sie fördern auch die Ausbreitung von Blattläusen und schädigen empfindliche Pflanzenwurzeln durch ihre unterirdischen Bauten. Mit GREEN GUARDIA Nematoden gehst du gezielt gegen Ameisennester im Boden vor – biologisch, effektiv und ganz ohne Chemie.
Wie viele Nematoden benötige ich?
Wähle die passende Packungsgröße entsprechend deiner Gartenfläche und Wassermenge. So stellst du sicher, dass sich die Nematoden optimal im Boden verteilen:
Packungsgröße | Fläche | Anzahl Pflanzen | Wassermenge |
---|---|---|---|
2 Mio. | 4 m² | 20 | 2 l |
3 Mio. | 6 m² | 30 | 3 l |
4 Mio. | 8 m² | 40 | 4 l |
5 Mio. | 10 m² | 50 | 5 l |
6 Mio. | 12 m² | 60 | 6 l |
10 Mio. | 20 m² | 100 | 10 l |
15 Mio. | 30 m² | 150 | 15 l |
20 Mio. | 40 m² | 200 | 20 l |
25 Mio. | 50 m² | 250 | 25 l |
50 Mio. | 100 m² | 500 | 50 l |
Einfache Anwendung in 3 Schritten:
- Anmischen: Löse das Nematodenpulver in der passenden Wassermenge vollständig auf.
- Ausbringen: Gieße die Lösung direkt in und um die Ameisennester oder auf betroffene Pflanzflächen.
- Nachsorge: Halte den Boden für mindestens 14 Tage feucht, damit die Nematoden aktiv bleiben und die Ameisenlarven abtöten.
Geeignete Anwendungsbereiche:
- Terrassen & Gartenwege: Nematoden wirken direkt gegen Ameisenkolonien unter Steinplatten oder Fugen.
- Beete & Pflanzkübel: Verhindere das Untergraben von Wurzeln durch Ameisennester im Boden.
- Gewächshäuser & Hochbeete: Effektiver Einsatz auch in geschützten Anbausystemen.
- Balkonkästen & Topfpflanzen: Besonders geeignet für urbane Begrünung mit natürlichem Schutz.
- Ökologischer Gartenbau: Ohne Chemikalien – sicher für Mensch, Tier & Umwelt.
🐜 Tipp: Ameisen verschwinden nicht sofort – gib den Nematoden 1–2 Wochen Zeit, um im Nest zu wirken. Eine Wiederholung nach 3–4 Wochen kann sinnvoll sein.
Was tun bei Ameisen im Garten oder Haus?
Ameisen sind wichtige Nützlinge in der Natur – doch in großer Zahl können sie im Haus, auf der Terrasse oder im Hochbeet zur Plage werden. Sie bauen weit verzweigte Nester, unterhöhlen Pflaster, dringen in Küchen ein oder schützen Blattläuse auf Pflanzen, um deren Honigtau zu sammeln.
Typische Anzeichen für einen Ameisenbefall sind sichtbare Straßen, kleine Häufchen aus Sand oder das plötzliche Auftreten in Vorratsschränken. Im Garten können sie durch ihre Bautätigkeit Pflanzenwurzeln freilegen und schwächen.
Wie kann ich Ameisen natürlich und nachhaltig vertreiben?
- Nematoden ausbringen: Mit GREEN GUARDIA Nematoden (z. B. Steinernema feltiae oder carpocapsae) kannst du Ameisen im Boden gezielt stören und die Kolonie langfristig vertreiben – ganz ohne Gift.
- Ameisennester lokalisieren: Suche gezielt nach Nestern oder Haupteingängen und gieße dort die Nematodenlösung direkt ein.
- Blattläuse kontrollieren: Entferne Blattläuse an Pflanzen – so entziehst du Ameisen eine wichtige Nahrungsquelle.
- Kücheneintritt verhindern: Verschließe mögliche Schlupflöcher, z. B. an Fensterrahmen, Türen oder Steckdosen.
- Gerüche nutzen: Ätherische Öle wie Lavendel oder Zitronengras wirken abschreckend, bieten aber keinen dauerhaften Schutz.
- Sauberkeit & Vorratsschutz: Verschließe Lebensmittel luftdicht und vermeide offene Zuckerquellen.
🌿 Tipp: Eine frühzeitige Anwendung von GREEN GUARDIA Nematoden bei ersten Anzeichen verhindert, dass sich Ameisennester dauerhaft ausbreiten – natürlich, effektiv und rückstandsfrei.

Nematodes are microscopically small roundworms that specifically combat soil-dwelling pests such as fungus gnat larvae, black vine weevils or grubs.
Depending on the species, nematodes control, among other things, fungus gnat larvae, black vine weevils, grubs, mole crickets, garden chafer larvae, ants, flea beetles, snails and meadow crane flies.
No, nematodes are completely harmless to humans, pets, and plants. They specialize in specific pests and cause no harm.
The nematodes actively penetrate the pest larvae and release bacteria that kill the pest. The nematodes then multiply in the dead larvae.
The first effects usually appear after about 5–7 days. Complete control takes up to 3 weeks, depending on the pest and the severity of the infestation.
Yes, nematodes can be used regularly in vulnerable areas to prevent pests, especially if there are recurring problems with fungus gnats or grubs.
Nematodes are proving to be more resistant to heat than often assumed. Thanks to secure shipping packaging, our SF nematodes can easily survive unrefrigerated shipping for up to a week, even during the summer months. Therefore, we rely on environmentally friendly delivery without cooling pads and unnecessary packaging waste.
The nematodes will be delivered directly to your mailbox in an envelope . Even for orders containing other products, we ship our nematodes in a separate envelope. This ensures fast and secure delivery. For this reason, unfortunately, the nematodes cannot be delivered to packing stations .
Yes, ideally, nematodes should be applied immediately upon receipt. They can be stored in a refrigerator at 4–8°C for a few days (see packaging).
Our nematodes are enriched with a biological substrate that sometimes changes shape during transport and due to temperature fluctuations. This may make them appear mushy or clumpy, but they are still perfectly normal and fully functional .
If you add the product to water and stir well, you will notice that everything dissolves well and can be used without any problems.
Live beneficial insects are non-returnable. However, we're happy to help you with any problems.

One application is usually sufficient. In cases of severe infestation or recurrence, a second application can be performed after approximately two weeks.
Nematodes require soil temperatures between 12–25 °C and a consistently moist environment – at least for several hours after application.
Nematodes are suitable for use in flowerpots, beds, lawns and greenhouses – both indoors and outdoors.
After controlling their host larvae, the nematodes slowly die when no new pests are present.
Yes, nematodes can be combined with other beneficial organisms such as predatory mites or parasitic wasps, as long as their habitats do not overlap.
