did mine in raiosed beds this year and haven't had a single carrot fly hole in any of them. Beds are only about a foot high. Is that too high for the fly or was I just lucky?

[DD.]

Lucky!

[simpson-allen]

Aaaah. How high should I put up  a barrier next year then?

[DD.]

The recommended height is 24", but whilst they can't fly high, they can get blown over.

I used a 24" barrier with reasonable effect for a few years, but the last two I switched to a total cover with Enviromesh. Not seen a single one since.

It could of course just be that there aren't any around your area!

They say that the carrot fly cant fly abover around 2 or 3 foot, however, this doesnt mean to say that the wind or a slight breeze cant blow them up onto your carrots, if i was you, i wouldnt be too bothered about how high your bed is, but if you do want to protectt hem next year use something like enviromesh or a fleece

[DD.]

I thought that's what I said!!!

[fatcat1955]

Presactly what you said.

[Jamie Butterworth]

Oops, sorry DD, didnt realise you had posted before me

[bigben]

Or of course you could use enviromesh or fleece

Hi All,
  I used debris netting over mine useing canes and water pipe to make the cover this year after the crop being totaly devistated by the little sods last year and to date I have had no sign of them  at all.
Regards,
Chris

The top of my carrot box is about 5 feet off the ground and I had no carrotfly this year 

[DD.]

I grow 3 x 32' rows of carrots, so that solution is not practicable for me!

[mashauk]

I grow them in baths every year as our ground is too stony, never had carrot fly.
