Nematodes for houseplants

What are nematodes and how do they work?

Nematodes are microscopic, living organisms that naturally occur in soil. They have been used for many years as a biological solution to control pest insects in plants. Econema nematodes penetrate the larvae of harmful insects and eliminate them from the inside. They are completely safe for people, pets and plants.

For houseplants, nematodes mainly work in the potting soil, where many pests spend their larval stage. By applying the nematodes evenly, the infestation is tackled at its source.

When should you use nematodes for houseplants?

Nematodes are suitable for houseplants affected by, among others:

• fungus gnats
• thrips (larvae in the soil)
• mealybugs (partly in the potting soil)
• aphids (nymphs around the stem and pot edge)

Use nematodes as soon as you notice weakened plants, small flies around the pot, or damage to leaves and roots. The earlier you start, the more effective the treatment.

Step 2 – Preparing the base solution

Dissolve the entire packet of nematodes in 1 litre of water.

• Stir gently but thoroughly
• Make sure the nematodes are evenly distributed
• Let the solution rest for a few minutes

Always use the full package per treatment. Storing partial doses is not recommended, as nematodes are living organisms.ige verpakking per behandeling. Deelverpakkingen bewaren is niet aan te raden, omdat aaltjes levende organismen zijn.

Step 3 – Diluting and applying

Mix the base solution with the water you normally use to water your plants.

Guideline per plant

• Small houseplant: approx. 200 ml
• Medium houseplant: approx. 300 ml
• Large houseplant: approx. 400 ml

Distribute the solution evenly over the potting soil so the entire root zone is reached.

Only use what you apply the same day.

Step 4 – Aftercare and repetition

After application, it is important that the nematodes remain active.

• Keep the potting soil lightly moist for at least two weeks
• Avoid direct sunlight on the soil
• Do not use chemical products

Initial improvement is usually visible within 1 to 2 weeks.
If the infestation persists, the treatment can be repeated after a few weeks. is vaak zichtbaar binnen 1 tot 2 weken.
Bij een aanhoudende plaag kan de behandeling na enkele weken worden herhaald.

Important tips for best results

• Ideal temperature: 10–25 °C
• Use nematodes as fresh as possible
• Store unused packages in a cool place
• Overdosing is unnecessary, but underdosing reduces effectiveness
• Good plant hygiene helps prevent reinfestation
