I know birds eat aphids and greenfly but do they eat black flies too?  I noticed two stalks of my philadelphus were covered in tiny black flies and I cut the tips off, sprayed them, wrapped them up and put them in the bin.  I'm just wondering, instead of trying to get rid of them like that - if i could put the stems on the bird table because the flies stayed on them even when I'd snipped them. 


The birds keep the green aphids down for me, but they don't seem to like blackfly around here.  Perhaps they taste nasty?  I'm not going to test that theory though!

ah my philadelphus was covered in blackfly too yesterday, obviously a favourite plant with them 


Am I right in thinking, as we have had quite a mild winter there will be more bugs than usual?  The greenfly on my lupins are enoumous and prolific!  



No, I haven't seen birds eat blackfly. But I have seen ladybird larvae and hoverfly larvae eat them. Ladybird and hoverfly larvae look fairly similar to blackfly if you don't pay attention, so it may be possible to throw the baby out with the bathwater.


Thanks for the info & link, Bob.     Will commence battle with them tomorrow.
