Fungus gnat larvae can build up quickly in damp compost, particularly around houseplants, seed trays and indoor containers. These nematode pods provide a practical way to treat the problem directly in the growing media where larvae develop. Each pod contains live beneficial nematodes held inside a biodegradable capsule. Once placed into moist compost, the capsule begins to break down and releases the nematodes into the soil. They move through the compost to find fungus gnat larvae, helping reduce pest numbers below the surface where root damage begins. This treatment focuses on the larval stage of the pest lifecycle, making it useful for reducing repeat infestations in indoor growing spaces, greenhouse propagation trays and potted plants. The pods are easy to apply and give a measured way to distribute nematodes evenly across the soil surface, helping support healthier roots and stronger young plants. Fungus Gnat Larvae Damage Plant Roots Although adult fungus gnats are often the most visible sign of an infestation, the larvae in the compost cause the main problem. They feed on fine roots and organic matter in the soil, which can lead to weak growth, poor establishment and damaged seedlings. These nematode pods help reduce larvae populations before more adults emerge. How to Use Nematodes Pods for Fungus Gnat Control Water the soil first, then press a pod into a small hole every 3cm across the surface. Cover lightly and water again. Keep the compost moist for at least 4 weeks so the nematodes can remain active. Use before the expiry date and keep refrigerated to help extend product life. Please note: Expiry date is around two weeks, this is a live product and is non returnable. Use the whole pack before the expiry date of the product. Targeted Application for Pots and Indoor Containers Each pack contains 200 nematode pods suitable for both small and large pots. These pods provide a slow release method for fungus gnat control in houseplants, greenhouse trays and propagation systems. They can be used as a preventative treatment or applied when fungus gnat activity is first noticed. Sizes Pack Size: 200 Nematode Pods Specifications Application Area: Up to 20 small pots (12cm) or 8 large pots (20cm) Storage: Refrigerate, use within 8 weeks Release Method: Slow release biodegradable capsule Frequently Asked Questions What are nematodes for fungus gnats? Nematodes are microscopic organisms that naturally target fungus gnat larvae in compost. They help interrupt the pest lifecycle by attacking the larvae before they develop into adults. How do I apply nematode pods for fungus gnat control? Place one pod every 3cm across moist soil, then cover lightly and water. Keep the compost moist for at least four weeks so the nematodes can move through the soil effectively. How long do nematodes last once applied? After release into the compost, nematodes remain active for up to 4 weeks. Moist soil conditions are important so they can continue moving through the growing media and locating larvae. Do nematodes kill adult fungus gnats? No, nematodes target the larval stage rather than the adult flies. By reducing larvae in the compost, they help lower the number of adults that appear later. Are these nematode pods suitable for indoor plants? Yes, they are suitable for houseplants, seed trays and potted plants where damp compost creates suitable conditions for fungus gnat breeding. How should I store unused pods? Keep unused pods refrigerated and use them within 8 weeks of purchase. Do not freeze them or leave them exposed to heat.
