The carrot fly is a pest for all gardens, and mainly affects carrots, but can also attack parsnips, parsley and celery. Around early may the flies lay their eggs around the developing carrots; the larvae, once hatched, burrow into the root.
To help prevent against the carrot fly one can erect a barrier around the crop at least 60cm high, as female carrot flies are very low flying this will prevent them from landing on the carrots and laying eggs.
Alternatively horticultural fleece or crop protection fleece may be used as a floating mulch to cover the crop. We have different type of fleece at our base in birr and can send it via post or courier if people require it. You can view more details about it on our website.
