The Carrot Root Fly (Psila rosae) is a small black fly that lays eggs which develop into creamy-yellow coloured larvae. There are normally two generations of Carrot Root Fly each year, one from May to June, and the next from August to September.
Carrot Root Fly larvae damage Carrots and other vegetables such as Parsnips and Celery. The larvae burrow into the vegetables, making tunnels. Symptoms of infestation will show as rusty brown scars on the produce. Damage can become so extensive that vegetables become inedible. An early sign of infestation can be identified by a blue-purple colouring on Carrot plant foliage.
Our Carrot Root Fly Traps help monitor Carrot Fly populations, and reduce the number of egg laying adults, by catching them on the specially coloured sticky traps which act as an attractant to the pests.
If you suspect Carrot Root Fly are already present, our Carrot Root Fly Nematodes can be applied to the soil or raised beds where the vegetables are growing. The nematodes will move through the soil to locate the Carrot Fly larvae and will help to significantly reduce their numbers. The nematodes remain active in the soil for three weeks, so repeat applications may be required. Applications should be made for each crop of vegetables. There is no harvest interval required as our nematodes are harmless to humans.
