Once the eggs hatch, the maggots begin to tunnel along the roots, making their way to the end closest to the root. Vegetables infected by this fly turn black from the burrows the larvae dig, and the leaves turn yellow.

How can I get rid of carrot flies?
To get rid of this pest, it is important to first rotate crops. This is a type of vegetable rotation where the location of the vegetables changes each season. In addition, some carrot varieties are more resistant to carrot flies than others, for example, Sytan, Flyaway, or Tilques. Make sure that no wild carrots are planted in the vegetable garden. If this happens, you must remove them immediately, as they attract even more flies.
