Is the Carrot Fly done yet

It is still possible that carrot fly could be around but as the weather cools the pupae are more likely to remain in the ground for the Winter rather than hatching into adults and laying eggs on your crops.

Lift the mesh. Weed and pull some carrots. You could probably leave the mesh off now but as you have it there you really might as well replace it.

I will keep mine in place until the end of the month and then remove it.
