Nematode Duo for Gnat and Thrip Control + 20 Free Sticky Traps - 10 Million Nematode Pack for Each

The pack contains two distinct strains of nematodes, each specialized for a specific pest.

The midge nematodes (Steinernema feltiae) target the larvae that live in the moist substrate, where they feed on the roots. The thrips nematodes act on the foliage where these sap-sucking insects hide.

Apply the midge control products by watering the substrate, and the thrips control products by foliar spray at the end of the day to avoid rapid evaporation.

Never mix the two sachets: each strain has its optimal environment of action.

Water temperature and application time are crucial for treatment effectiveness.

Use water between 15 and 20°C, never chlorinated. Let tap water sit for 24 hours or use filtered water. Dilute one sachet in 2 to 5 liters depending on the surface area to be treated.

For midges: water a substrate that is already moist; nematodes need moisture to move. For thrips: spray in the evening; the sun's UV rays deactivate them.

Keep the substrate moist for 2 weeks after application, but never soak it.

Nematodes are compatible with all houseplants without exception, from the most robust to the most delicate.

These microscopic organisms only attack targeted insects thanks to symbiotic bacteria they release. Your roots and leaves remain perfectly intact.

They are particularly recommended for Calatheas, Alocasias and other sensitive plants that cannot tolerate chemical treatments.

However, be aware that nematodes need moisture to survive. On xerophytic plants (cacti, succulents), their effectiveness will be limited by a dry substrate.

Reinfestation generally indicates a life cycle that is not completely interrupted or a persistent external source.

Nematodes eliminate the larvae but not the eggs already laid or the flying adults. This is why yellow traps are essential: they capture the adults while the nematodes work deeper inside the soil.

A second treatment after 15 days targets the new generation emerging from the surviving eggs. Without this booster, the cycle begins again.

Also check for sources of stagnant moisture: full saucers, overly compacted substrate or decomposing organic matter attract new midges.

Nematodes are compatible with most treatment practices, but certain combinations render them ineffective.

Avoid any treatment with black soap or insecticides in the 48 hours before and after application: these products can kill the nematodes.liquid fertilizercan be used one week after treatment.

The ideal combination: continuous yellow traps + nematodes every 2-3 weeks until complete eradication. A well-draining substrate such asUniversal SubstrateIt also limits conditions favorable to midges.

Nematodes coexist perfectly with the beneficial microorganisms in our enriched soils.

Nematodes offer targeted and long-lasting action where insecticides act on the surface and temporarily.

A chemical spray kills visible adults but does not affect the larvae buried in the substrate. The midges reappear as soon as the effect wears off. Nematodes, on the other hand, actively hunt the larvae in their habitat and multiply there as long as prey is available.

Another major advantage: no resistance develops, unlike with insecticides which populations eventually come to tolerate.

The only drawback: nematodes require patience and optimal conditions. Expect to see the first results in 2 to 3 weeks, compared to the immediate but short-lived effect of sprays.
