I'd have to agree with Bob. Nasty little critters! Got them here as well.

Can be avoided by placing a 2ft high plastic barrier around your carrot bed or grow in a 2ft high raised bed.

Or covering with fleece...as I do 

Covering with fleece works every time for me. Good luck next time.

I'd definitely go with the fleece / mesh protection. I know carrot fly are supposed to fly below 45 - 60 cm but my raised beds are higher than this & I still have a problem with this pest - mesh is the only thing that works for me.

Thinning out seedlings can exacerbate the problem as the smell attracts the flies. Best, therefore, to always sow very thinly.

I grow groups of chives round mine but never had it, dad reckons she cant fly this high above sea level. I dont know if he's having me on, but in all the years he's grown them the fly has never struck.

Your dad is sort of correct Lyn. Carrot flies are weak flyers and rarely go about 2ft  from the ground. So a barrier (like a raised bed and a fleece cover as has been suggested) around carrots helps.

Chives and other strong smelling plants only masks the smell of the carrot but it does deter them.

Carrot fly tend to spend winter and early spring on cow parsley (or parsnips) and then move on to your seedlings. 

The real trick with carrot fly is not to leave any carrots or parsnips in the garden over winter

Hello all thanks for the info , never had carrot fly before , must have attracted the blighters when dug some up before because thre carrots where fine

Never thin out and have in the past sown between Garlic 

You live and learn with gardening 

Not sure carrot flies have read,the script.  So 70 cm, 80 cm or 90cm?   

I have pretty good conditions for growing carrots...sandy loam......and always use onions and spring onions as companion planting.  By the way, parsley too gets carrot fly so same cultural requirements.  My veg patch has a mixed low evergreen hedge to one side, a lavendar hedge on another, and runner bean framework to another.  Also enough taller growing plants to,,in theory, deny the carrot fly.  however, I need to apply fleece to effectively deny carrot fly.

pests will get access one way or another such is their instinct to feed, breed and survive.

Not so sure Verdun. I think they may have read the script.

The traditional remedy is to surround the carrots with string soaked in paraffin.  Never tried that.  If you do thin, either do it on a wet day or water afterwards to damp down the smell and settle the soil.  Anything to stop the lovely carroty smell getting out.  But I think fleece is the best answer.  Or do what my mum does and grow them in containers on her first-floor balcony.

What is the best way to store carrots for the winter without leaving them in the ground?

I found a web article that said leave them in there, covered in straw and horticultural sheeting. So did.

Dug some up yesterday and it looks like I have the same problem as GWRS. Still have loads of them in the ground too.

A neighbour once soaked rags with creosote and posted them as mini flags all over his garden.  "to deter badgers, rabbits and foxes" he said.  

The smell.  And the appearance.  And it didn't deter these creatures.

For the past two years all my carrots have had carrot fly attacks, even the ones grown in containers atop an outside work bench [especially the purple carrots.] This year I surrounded them with a 1 mtr high Vegimesh fence fixed to canes and the carrots were perfect.

The advantage I find with a fence, over mesh being laid over the carrots, is that you do not have to uncover the carrots to weed with an onion hoe or when thinning them out. But then I am rather tall with a long reach !

Vegimesh is quite expensive, so for a larger plot next year I am going to use the heavyweight fleece I have used this year to cover my cabbage. It really is very strong compared to the lightweight version which I find a waste of space.

MelM , heavy weigh fleece , never herd of it ? Wondered where you got it ?

You are quite right the lightweight stuff does just disintegrate
