White fly in greenhouse

[trish60]

My greenhouse cucumbers have been fantastic but have suddenly become covered in white fly. The neighbours probably think I m potty as I ve been out with my rechargeable Dyson hoovering the leaves but loads fly up off & just land back on the leaves when I go.
What can I do?
