Pansyface, I think she will be very relieved to hear that is what they are. She has had those little black flies every summer, in fact so have I - although it's the first time she has noticed anything in the actual soil. In your experience does that also explain the mess round the pots? I don't think she will have a problem using the bug killer. Amazing that the maggots are bigger than the actual flies - but eurgh. I hope this doesn't put her off. I'm delighted that she is acquiring green fingers.
Thanks very much for your help.
