Nematodes

Sciarid flies (or Fungus flies) are 3-4 mm long black flies that jump or hover over the soil surface in the greenhouse and around houseplants where compost is warm and moist.

The fly can spread diseases and the larvae cause damage to seedlings and cuttings

The small white larvae live in the top few millimetres of compost, attacking rooted cuttings and seedlings.

The larvae can be controlled with nematodes.
