GREEN GUARDIA HB nematodes – Biological help against vine weevils & grubs
Controlling vine weevils and protecting roots
The favorite midnight snack of beetle larvae? Your favorite plants, of all things. Gnawed leaf edges, weakened plants, and suddenly dying roots. The vine weevil doesn't just leave unsightly notches on the leaves; the real damage happens underground. Its larvae feed unnoticed on the delicate plant roots. Grubs and other soil-dwelling pests behave similarly destructively, ruining the root zones of lawns, flowerbeds, and fruit trees. Therefore, if you want to effectively control the vine weevil, you should eliminate the larvae directly in the soil.
Vine weevil nematodes – come to drive them away
The problem affects ornamental gardens as well as balconies, greenhouses, raised beds, and planters. Rhododendrons, yews, strawberries, perennials, cherry laurel, and fruit trees are particularly susceptible to the vine weevil. White grubs, on the other hand, prefer to infest lawns, potted plants, or containers. If you notice that your plants are stunted despite adequate care, an infestation in the soil is very likely. An infestation of both white grubs and vine weevils in the same garden is not uncommon and requires targeted biological treatment. No one is safe from this feeding frenzy.
Also combat grubs, completely naturally
This is where our tiny helpers come in. Heterorhabditis bacteriophora (HB nematodes for short) are microscopic roundworms that act as natural enemies in the soil. They penetrate the larvae of the pests, thus interrupting their life cycle. After a few days, the pests die, while the nematodes continue to reproduce as long as they find food. Anyone wanting to successfully control grubs will find our beneficial nematodes to be the perfect, chemical-free, and residue-free solution – ideal for organic gardening. They are completely harmless to humans, pets, bees, birds, plants, and other beneficial insects.
Order nematodes against vine weevils conveniently online
With our vine weevil nematodes, you're choosing safe, sustainable pest control. You can buy them directly online from us. Delivered ready to use, they quickly restore the biological balance in your pots, containers, and beds. Who has the biggest nose now?
🌿 Conclusion: With GREEN GUARDIA HB nematodes, you are choosing an effective, sustainable and residue-free solution against soil-dwelling pests such as vine weevils and grubs – completely without chemicals and safe for the environment and beneficial insects.

- Bodenfeuchtigkeit & Bodentemperatur: Den Boden für 1–2 Wochen durchgehend gleichmäßig feucht halten. Die optimale Bodentemperatur für die Anwendung liegt zwischen 12 und 28 °C.
- Keine Chemie: Sowohl vor als auch nach der Anwendung vollständig auf chemische Pflanzenschutzmittel verzichten, um die Wirkung der Nützlinge nicht zu gefährden.

FAQ Nematodes
Do you have questions about our products, application, or shipping? Here you will find the most important answers at a glance. Should anything remain unclear, please feel free to contact us!
Nematodes are microscopic roundworms that specifically target and biologically control soil-dwelling pests such as fungus gnat larvae, vine weevils, or white grubs.
Depending on the species, nematodes combat fungus gnat larvae, vine weevils, white grubs, mole crickets, garden chafer larvae, ants, flea beetles, slugs, or crane fly larvae.
No, nematodes are completely harmless to humans, pets, and plants. They are specialized in specific pests and do not cause any damage.
The nematodes actively penetrate the pest larvae and release bacteria that kill the pest. The nematodes then reproduce inside the dead larva.
As a rule, the first effects become visible after about 5–7 days. Complete control takes up to 3 weeks, depending on the pest and the intensity of the infestation.
Yes, nematodes can be used regularly in at-risk areas to prevent pests – especially if there are recurring problems with fungus gnats or white grubs.
Nematodes have proven to be more robust against heat than often assumed. Thanks to secure shipping packaging, our SF-nematodes can easily survive unrefrigerated shipping for up to a week, even in the summer months. Therefore, we opt for environmentally friendly delivery without cooling pads and unnecessary packaging waste.
The nematodes are delivered directly to your letterbox 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, nematodes unfortunately cannot be delivered to parcel stations (Packstationen).
Yes, ideally nematodes should be applied immediately upon receipt. Storage in the refrigerator at 4–8°C is possible for a few days (see packaging).
Our nematodes are enriched with a biological substrate that sometimes changes form during transport and due to temperature fluctuations. This can make them look mushy or clumpy, but this is completely normal and they are fully functional.
If you add the product to water and stir well, you will notice that everything dissolves nicely and can be applied without any problems.
Live beneficial insects are excluded from exchange. However, we are happy to assist you if there are any issues.
Shipping information
- Fresh shipping: Orders placed from Monday to Friday before 5:00 AM are shipped fresh daily.
- Weekend orders: Orders placed after Friday 5:00 AM will be shipped on the following Monday to ensure the freshest beneficial insects.
Nematodes are mixed with water and applied to the infested areas using a watering can or a spray system. The soil should be well-moistened beforehand.
One application is usually sufficient. In cases of severe infestation or re-occurrence, a second application can be performed after approx. 2 weeks.
Nematodes require soil temperatures between 12–25°C and a consistently moist environment – for at least several hours after application.
Nematodes are suitable for use in flower pots, flower beds, on lawns, and in greenhouses – both indoors and outdoors.
After they have controlled their host larvae, the nematodes gradually die off when there are no more pests present.
Yes, nematodes can be combined with other beneficial insects such as predatory mites or parasitic wasps, provided their habitats do not overlap.
Please contact us directly with a photo of the delivery and your order number.
Yes, every shipment includes instructions on how you can download them digitally on our website.
Yes, our nematodes can also be used for pest infestations on crops such as vegetables. They are completely harmless to humans and pose no health risk even if accidentally ingested.
No, our nematodes cannot be overdosed. They control pests until there are no hosts left, and then die off naturally. The exact application quantities can be found in our digital instructions.
Yes, nematodes are an approved method of biological pest control and are suitable for organic farming.
The clay powder or gel is harmless and can simply be spread in the garden or disposed of with household waste.
