How do you recognise the infestation?

It is possible that the damage caused by the fungus gnat is not immediately recognised. This is because the larvae are active in the soil. They are particularly fond of the stems and roots of seedlings, young plants and cuttings. This damage to the plant prevents nutrient uptake and weakens it further. Damaged roots are also more susceptible to bacteria and fungi. Wilting and reduced plant growth are common symptoms of a fungus gnat infestation. We use the following glue trap from Andermatt Biogarten for control:

How can (further) damage be prevented?

Removing dead plant debris can prevent further damage to the plant. Also take care not to overwater the plant. The fungus gnats prefer to lay their eggs in moist soil. Another tip is to cover the base of the plant with a layer of sand. Fungus gnats cannot penetrate this layer and therefore cannot lay eggs in the soil. If the larvae are in the soil, the best way to combat them is with biological beneficial organisms.
We recommend the following organic products from Andermatt Biogarten:
- Solbac
- Nematoden
 

The animal

Fungus gnats are small, dark-coloured gnats with long antennae and legs. They are between 3 and 5 millimetres long. They prefer to stay in a warm and humid environment, close to plants. In greenhouses they can also occur all year round. After mating, the females lay between 50 and 200 eggs, which hatch within two to three days.
