Thanks folks, I never heard of sciarid fly before but I think I may have had them once on my mushrooms. (stop sniggering this is family site)
I am considering taking the ginger out of the compost and giving it a wash in slightly warm water then replanting in new compost. Does that sound like a good idea?

I'd be wary of doing that, gypsy, in case you damage any roots which have already developed.

Far better just to let the compost dry out a bit

ok I will give it a few days then, trouble is the flies are in the house. thanks
