My lupins are currently magnificent but I notice today covered in white fly . Is there anything I can use that will not affect bees or other wildlife?

These are greenflies, they leave their white skins behind as they moult. This species only affects lupins but can do so very severely, causing flower stems to collapse. A spray of water reduces numbers but they build up again and a greenfly spray might be needed.
