How to get rid of the carrot fly?
To get rid of this pest, it is important to first rotate crops. This is a kind of vegetable rotation by changing the location of the vegetables each new season. Also, some varieties of carrots are more resistant than others to the carrot fly, such as Sytan, Flyaway or Tilques. Be careful not to have wild carrots in the vegetable garden; if this is the case, they must be removed immediately, as they attract more flies.
It would also be wise to place insect nets when the vegetables start to emerge from the ground. The net or protection put in place must remain in place until October. A mulch of wormwood, rosemary or lavender around the carrots can also keep carrot flies away thanks to the odors given off by these plants.
Finally, spraying onion or garlic manure undiluted in water applied to the carrots twice a week can stop the start of contamination. This will also fertilize the soil and care for the plants and vegetables.
