Are there all sorts of things flying around your houseplants, or is your plant deteriorating for no apparent reason?
Houseplants can be affected by various pests, often without you realising it straight away. The damage starts underground or on the leaves, whilst the plant slowly deteriorates. On this page, you can see which pest corresponds to which symptoms and how to get rid of them quickly and without using pesticides.
Protect your houseplants with the right nematodes
What pest does your houseplant have?
Houseplants can suffer from various pests, often without you noticing immediately. These are the most common culprits.
- Fungus Gnats - Small black flies that fly up when you touch the plant. The larvae feed on the roots in the potting soil, causing the plant to slowly deteriorate.
- Thrips - Barely visible but their damage is. Silvery spots on the leaves and discoloured flowers are the most recognizable signs.
- Fruit Flies - Small brown flies with red eyes that fly around plants and fruit. They lay their eggs in moist potting soil and rotting organic matter.
- Aphids - Small soft insects that accumulate on young shoots and leaves. They suck plant sap and quickly weaken the plant.
- Spider Mites - Almost invisible but recognizable by fine web-like threads on the leaves and yellow-speckled leaves. Primarily occurs in dry indoor air.
Nematodes for healthy houseplants
Nematodes are microscopic roundworms that naturally live in the soil. They seek out larvae, penetrate them, and stop the pest. No chemicals, no fuss. Just nature doing its job, even in your potting soil.

How to use nematodes for houseplants?
Applying nematodes is easier than it sounds. Dissolve them in water and pour the mixture directly into the potting soil of the affected plant. Make sure the potting soil is moist before and after application; this will allow the nematodes to quickly penetrate the soil and start working immediately.
Frequently asked questions
Yes. Nematodes are a proven biological method to control larvae in potting soil. They actively seek out the pest and kill it without toxins or chemicals, safe for your plant.
The first results are often visible within 1 to 2 weeks. With fungus gnats, you'll notice this because fewer gnats fly up when you touch the plant. The plant then gradually recovers.
In case of a severe infestation, or if the pest returns, a repeat treatment is recommended after 2 to 3 weeks. Nematodes target the larvae but not the eggs, so a second treatment ensures that the new generation is also controlled.
Yes, completely. Nematodes are naturally present in the soil and pose no risk to people, animals, or plants. You can also use them preventatively without any harmful effects.
That depends on the number of plants and the size of the pots. On our product page, you can find out exactly how much you need for your situation per product.
Yes. Because houseplants are indoors, the temperature is suitable for the nematodes to be active all year round. You do not have to wait for a specific season.
