Sciarid Fly Control - also known as compost fly is a common pest of greenhouse plants. 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. To treat Sciarid fly, mix the nematodes with water and water directly into the affected pots / trays. Each pack of nematodes pack will treat up to 15 sqm of compost. For smaller areas just make the solution stronger (you cannot overdose)
