Product Description

Text reads 'gardening naturally SCIARID FLY NEMATODES'. Product packaging showing illustrated fly on tan and blue curved design.

Sciarid Fly Nematodes

Sciarid fly (also known as fungus gnat or compost fly) is a troublesome pest of houseplants and plants in greenhouses and conservatories.

The larval stage of the sciarid fly attacks the roots of plants and may cause the death of seedlings. These nematodes will attack the larvae which will in turn significantly reduce the Sciarid fly.

Easy to apply, just water the nematodes into the soil.

Completely harmless to children, pets and wildlife.

Suitable for use on fruit and vegetables and they can be eaten straight after application.

This is a mix of Steinernema Feltiae and Steinernema carpocapsae nematodes.
