Other Effective Methods of Protection

The most effective way of protecting carrots is to set up a barrier so that the carrot fly cannot lay it’s eggs around your carrots. There are many ways to achieve this including containing your carrots inside a 2 foot high screen. The best material for this is a fine mesh (like net curtains).

Growing your carrots in a raised bed that is over 2 foot above the ground as the carrot fly cannot fly higher than 2 foot.

I find covering the carrots in a row cover with fine mesh and burying the edges under the soil is the most effective defence against carrot fly.
