Carrot Root Fly Nematodes are microscopic worms which seek out Carrot Root Fly larvae and eggs in the soil then feed and multiply inside to stop them feeding on your carrots. Nematodes are naturally found in the soil, by using this product you are simply topping it up.
Carrot root fly emerges from the soil between April to June and again from August to October. During these periods, they lay fresh eggs in the soil, which hatch into creamy-coloured larvae in just 7 days. These larvae feed on the roots of your carrots, eventually burrowing into them and causing extensive damage. The larvae of carrot fly are slim and have a creamy-yellow colour. As the plant roots develop and enlarge, the larvae mine into the roots, leaving unsightly characteristic reddish/brown tunnels below the skin surface. Initial signs include wilting and reddened leaves. Nematodes products contain Nematodes (microscopic worms) which are renowned biological control products, providing many benefits over traditional gardening chemicals and are a key ally for organic gardeners.
