Nematodes against thrips, mealybugs & fungus gnats
100%
Biological, no chemical substances
Packed in France
Ardèche
Fungus gnats
The main target: sciarid fly larvae that nibble at the roots in damp potting soil.
Thrips
The nematodes target their pupal stage, which takes place in the potting soil — a useful reinforcement alongside a foliage treatment.
Mealybugs & scale insects
Acts on the stages present in the potting soil; combine with a foliage treatment (neem oil) for complete action.
The species used
Living entomopathogenic nematodeA specialist in fungus gnats — its most reliable and best-documented use. It also targets the pupal stage of thrips, which take refuge in the soil to transform. Active over a wide range of soil temperatures (from about 10°C), with optimal efficacy between 14 and 26°C.
How they work
A natural mechanism, with no possible resistance01
The nematodes enter the larva through its natural openings.
02
They release their symbiotic bacterium (Xenorhabdus), which kills the larva within 1 to 3 days.
03
They reproduce on the spot: lasting protection, with no residue or resistance.
Application protocol
4 steps · no equipment1. Store
In the fridge (4 to 8°C), and use quickly after receipt.
2. Dilute
In cool water, below 25°C (ideally 15-20°C).
3. Water in the evening
In the shade: nematodes are sensitive to UV.
4. Keep moist
The potting soil, for 1 to 2 weeks, without excess water.
The combined attack
Nematodes in the soil, neem oil and traps on the foliage: a complete routine.
Frequently asked questions
Dangerous for pets or children?
No. These nematodes have no effect on vertebrates — they exclusively target certain insect larvae. Safe for humans, domestic animals and plants.
How long before results?
Once in contact, the target larva is neutralised within 1 to 3 days. The result visible on the plant depends on the level of infestation, generally within 2 weeks.
Does the treatment need repeating?
A second treatment 2 to 3 weeks after the first targets the larvae born in the meantime.
How should I store the sachet?
In the fridge between 4 and 8°C, never in the freezer. They are living organisms: use quickly after receipt.
Why water in the evening?
Nematodes are sensitive to UV and to drying out. Applying at the end of the day or in overcast weather preserves their effectiveness.
Which size should I choose if I have 4 or 5 plants?
The 6 to 12 plants size amply covers this need and works out cheaper per plant than two small sizes.
Your plants deserve better than a pesticide.
