Spray plants to kill adult flies before they can lay their eggs. Adult flies are most active late afternoon to early evening, so spraying at these times will be most effective. Any adult flies sprayed will be killed, as will any flies which land on treated foliage for up to 2 weeks after application.
Carrot flies can survive the winter in a variety of different ways. The adults can survive by sheltering in warm protected environments, the pupae can overwinter in the soil or the larvae can survive in the roots of host plants, especially in crops which have been covered with straw for protection from cold weather.

Grains, carrots, and potatoes are prime targets for wireworms. There are no effective insecticides against wireworm. Crop rotation will reduce damage. Keep the garden area free from weeds – particularly grasses.
Adult vegetable weevils, which are beetles with well-developed snouts, and their larvae feed on all parts of carrot plants. Vegetable weevil larvae are about 1/3 inch long, green, worm-like creatures that feed on carrots underground. Chewed carrot leaves could be a sign of adult weevil feeding.
Non-pesticides control Remove larvae of wireworms from soil as they are found. A mixture of nematode species for controlling vegetable pests is sold as Fruit and Vegetable Protection, the Nematode Heterorhabditis bacteriophora is also sold specifically against wireworm.
Companion planting. Completely encircling your carrot crop with allium family plants such as onions, leeks or chives is believed to literally throw carrot fly off the scent.

I feed the carrots and other veggies every three or four weeks with an organic fertilizer – currently a fish emulsion and seaweed blend, and I spray them with a solution of Epsom salts and water (1 teaspoon Epsom salts to 4 cups warm water).
