How High Do Carrot Flies Fly?

Carrot fly larvae are found in the root system of the host plant. The adult flies emerge in the early spring, after overwintering in the pupae. The female flies are found close to the susceptible hosts and may be as low as 18 inches off the ground. They lay eggs in the root surface of carrots, which are then eaten by the larvae. The transition from egg to adult takes about 3 months.

Pesticides that kill adult flies are not effective against the larvae or eggs of the carrot fly. Therefore, if you want to control the larvae population, you should consider using a barrier. This can be made of garden fleece, polythene, or a special barrier that is designed to protect against carrot flies. It is important to place the barrier at least 60cm above the ground. Once the barrier is in place, you can water the carrots to keep out the fly larvae.

If you’re concerned about the infestation of carrot flies in your garden, try sowing your carrots in the spring and harvesting them in the autumn. This will prevent them from damaging your crops. However, you need to be vigilant and check your vegetables regularly for any new pests. Learn all you can about the different types of pests that can attack your vegetables.
