black fly and Green fly

Hi my second year veg growing ... My Greenhouse  is full of new seedilings doing well except green and black fly.  Ive tried Organic bug spray ... plants that are companion plants in pots in the Greenhouse .... Yellow stickies to grap the flies as they pass but still the little blighters persist ... Need your help very much a novice

Thank you my friends

    Yes they are mostly edible Verdun.  No just a quick spray on top of leaves.  Will do under and around trays.  mmm Soap sprays I will have to check this out too

    Thank you for your Help Verdun

    Much appreciated

    Could you not move them outside for a few days and let the predators move in? No chance of frosts now.

    Have moved some of them out ... I was hoping the companion planting would work

    I thought the Green house was more of  protection but the little blighters still found them.  All seems calm with the soap wash at present will need to keep this up. Vedun how often to I need to do this?

    thank you all

    As and when with the soap sprays Ging.  You can jet them off just with water but not advisable when it's delicate seedlings! Fine with more robust shrubs and perennials etc. Apparently it makes the little b*****s explode....imageimage

    It's a place where beautiful isn't enough of a word....
