How Steinernema feltiae Works

✔ Fungus Gnat Control - Targets larvae in the soil, stopping the life cycle before adults emerge.✔ Root Pest Control - Attacks larvae of soil-dwelling insects like shore flies and certain thrips species.✔ Prevents Recurring Infestations - Continues working in the soil, providing long-term protection.✔ Safe for Plants and Pets - Does not harm beneficial insects, houseplants, or humans.

Highly effective: Best results occur in moist soil conditions at 15-25°C.

Best Conditions for Use Indoors

✔ Temperature: 10-28°C (optimal 15-25°C)✔ Soil Moisture: Keep soil damp for at least 2 weeks after application.✔ Apply in the evening or during low-light hours to protect nematodes from UV exposure.

🌱 Tip: Water plants before application to ensure nematodes can move freely through the soil.

How to Apply Steinernema feltiae on Houseplants

✔ Mix the sachet contents with lukewarm, chlorine-free water.✔ Stir gently and let the mixture settle for a few minutes.✔ Drench the soil of each plant using a watering can or sprayer.✔ For small pots - Use approx. 100 ml per plant.✔ For large plants - Apply up to 250 ml per pot.✔ Reapply every 4 weeks if pest pressure remains high.

What Pests Do Steinernema feltiae Control?

✔ Fungus gnats (larvae) - Stops infestations at the source.✔ Thrips (soil-dwelling larvae) - Reduces populations before emergence.✔ Shore flies and other soil pests - Targets larvae in damp conditions.

❌ Not effective against adult insects or pests that don’t inhabit soil.

🔹 For adult fungus gnat control, use sticky traps in combination with nematodes.

Storage and Handling for Indoor Use

✔ Use immediately upon arrival for best results.✔ Store in the refrigerator (4-8°C) for up to 2 weeks if necessary.✔ Do not freeze - extreme cold kills nematodes.

Pesticide Compatibility for Houseplants

Steinernema feltiae is sensitive to certain chemical treatments.

🚫 Avoid using:

Soil drenches with chemical pesticides - May kill nematodes.
High concentrations of hydrogen peroxide - Can harm beneficial organisms.

✔ Best Practice: If chemical treatments were recently applied, wait 5-7 days before introducing nematodes.

Common Issues and Troubleshooting

❌ Nematodes don’t seem to work?

Check soil moisture - Dry soil reduces effectiveness.
Monitor temperatures - Below 10°C or above 28°C may reduce nematode activity.
Was the application fresh? - Expired or improperly stored nematodes may not be viable.

❌ Still seeing fungus gnats?

Nematodes target larvae, not adults - Use sticky traps to catch flying gnats.
Repeat application every 4 weeks - Ensures coverage of new larvae hatching in soil.
Eliminate excess moisture - Overwatering encourages fungus gnat breeding.

Why Choose Steinernema feltiae for Houseplants?
