Also known as compost fly / fungus gnat, Sciarid fly is a common pest of greenhouse plants in the spring. Young bedding plants, especially bizzie-lizzies, can be affected with large numbers of small flies covering young plants, whilst larvae eat the roots. The Sciarid flies crawl over the compost surface and if disturbed fly on to the lower leaves. The larval stage in the compost attacks the roots and can kill young seedlings. Control sciarid fly naturally by applying Sciard Nematodes.
Sciarid Fly Nematodes are safe to use on food crops, safe for children, pets and wildlife and are easy to use - mix the nematodes with water and water directly into the affected pots / trays. Sciaird Fly Nematodes need a daytime soil temperature of 10°C. Safe for plants - will not scorch tender seedlings or young plants. Safe for you - use on plants in your living room or conservatory. The standard pack of Sciaird Nematodes pack will treat up to 15sqm of compost (for smaller areas just make the solution stronger - you cannot overdose) or for larger areas, the large pack will treat 50 sqm.
N.B. Sciaird Nematodes are a perishable product (it will keep for up to 2 weeks in the fridge), so please order when the pest is present and you are ready to treat.
