Onion fly

Has anyone got a tried and tested way to get rid of onion fly, and has anyone tried a flame gun on their soil to see if it kills off the fly?

The flies hatch twice yearly and will travel up to 1km. The only way I know is netting.

Yep! ^^^ what the Boss said!

Or you could grow from sets which are not affected.

All my sets were wiped out last year

Ah that was Allium leaf miner, do you think Spec has a problem with?

Your right Mark, perhaps Spec was refering to onion root fly

Yes it's root fly I was referring to, that's why I was wondering if a weed burner, one of the paraffin burners, would heat the soil enough to kill off any egg's and hibernating flyes?
