How to rid black fly organically?

Bagpuss57Bagpuss57 South West Posts: 256
Is there a a simple cheap solution I can use to spray my plants to rid black fly? They seem to absolutely everywhere and it's affecting the growth of some of my plants. I don't want to use the chemical bug spray but if there's something organic that I can make up at home that won't damage other wildlife but be able to wash off the bugs I'd rather do that instead. Anybody tried and tested home made solutions?

    I'm trying a home remedy of pure soap solution sprayed on greenfly. I hope it works as i dont want to hurt bees etc. Last year was very bad for greenfly on my lupins and apple tree and definitely too many to get off by hand. I was probably too late spotting them.

    Yes, that's what I've been doing so far but there are lots of plants with them and it's taking rather a long time. As I have a chronic fatigue issue I just thought there might be an easier and quicker way to rid them.

    Thanks Bijdezee I might try that. What is the ratio for soap/water?

    One tea spoon neem oil 2 tea spoons washing up liquid per litre of water well shaken. Worked for me on all sorts of soft flies and aphids

    Ideally use soft soap if you can get it not so harsh as detergent -  washing up liquid  has salt in it (NaCl) so be careful with that. You can buy or make up garlic spray solutions which act as a deterrent too  but it needs re-applying frequently. (weekly)

    Why do people equate organic with non-poisonous?

    I don’t know, B3.  Why do people equate organic with non-poisonous?
