Combating fungus gnats (fern fungus gnats) with nematodes

Fungus gnats: What are they and how do you combat them effectively?

Fungus gnats(Sciaridae), also known as fungus gnats, are small black flies that are often found around houseplants and potted plants in damp environments. While the adults are not directly harmful, their larvae can cause significant damage by feeding on the roots of plants. Fortunately, you can control fungus gnats naturally usingnematodes(nematodes).

How do you recognize damage caused by fungus gnats?

Fungus gnats are most damaging in their larval stage. The larvae feed on the roots of young plants, which can lead to weakened or dying plants. Here are the most common signs of a fungus gnat infestation:

• Presence of flies: Small black flies that hover around the base of plants or above the potting soil, especially in damp areas such as greenhouses and living rooms.
• Damage to roots: The larvae of fungus gnats feed on the fine roots of plants, resulting in wilting and poor growth of young plants.
• Poorly growing or wilting plants: Root damage can cause plants to wilt, not grow well, or in severe cases, die.

Indirect damage and additional risks

The damage caused by the larvae of fungus gnats to the roots weakens the plant, making it more susceptible to other pests and diseases. Young seedlings and cuttings are particularly at risk from root damage, which can seriously hamper plant growth.

Choose a natural approach

The most effective way to combat fungus gnats is to usenematodes. Nematodes, such asSteinernema feltiae,are natural enemies of the fungus gnat larvae and penetrate them to kill them from the inside. For optimal control, choose to use yellow sticky traps that are very effective for catching adult fungus gnats so that they can no longer lay eggs in combination with the nematodes against the fungus gnat larvae, you will be rid of your plague within a few weeks.

The advantages of this biological control method are:

• Environmentally friendly: Nematodes specifically target the larvae of fungus gnats and do not harm other beneficial organisms.
• Effective and sustainable: Under the right conditions, nematodes can significantly reduce the larval population of fungus gnats without the need for chemical pesticides.
• Safe for humans and animals: Nematodes are completely safe for children, pets and other animals, making them ideal for use in indoor and outdoor environments.

When to use nematodes against fungus gnats?

The best time tonematodescan be used against fungus gnats when the soil temperature is between10°C and 25°Cis.Steinernema feltiaeNematodes work best in humid conditions, such as in potted plants or greenhouses, where fungus gnat larvae are common. Mix the nematodes with water and apply to affected plants. Keep the soil moist after application so that the nematodes can spread well and effectively control the larvae.
