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 introducing Hypoaspis Miles predators to target the eggs and larvae of Sciarid Fly.
Hypoaspis Miles is a tiny predatory mites that lives in the soil / compost around the plant stem and feeds on the eggs and larvae of sciarid fly and on the pupae of thrip. Hypoaspis needs a daytime temp of 15c and prefers moist conditions (but not waterlogged) and comes in a shaker tube containing vermiculite which is simply sprinkled over the affected plants. Hypoaspis can survive for approx 4 weeks without food, so it is ideal for introducing as a preventative treatment. Once the pest is present, each Hypoaspis can eat 8 sciarid fly larvae per day making it a very effective control. Apply 100 Hypoaspis per sqm as a preventative treatment i.e. a pack of 10,000 will treat 100 sqm, but apply double for mild infestations or even 500 Hypoaspis per sqm for heavy infestations i.e. 10,000 hypoaspis will treat 20 sqm. For heavy infestations it is good idea to treat with Sciaird Nematodes as well - CLICK HERE to find out more. Hypoaspis is a living predator, so order when you are ready to use and insecticides have not been used. Available in shaker tubes of 10,000 (treats up to 100 sqm) or 25,000 (treats up to 250 sqm).
