Hello. We have around 20 beech trees at the bottom of our garden and the are covered in white flies. The whole of the garden is inundated with these flies. Have you any suggestion how to get rid of them. Look forward to hearing from you.
Kind regards

If its any consolation, I've just mown my lawn and as the mower brushed against the beech hedge clouds of white flies emerged from it. Grrrrh.

Just joining in because I'd like to see the replies. it looks like a mammoth task. You could try spraying your garden with garlic solution to repel them but you can hardly spray 20 beech trees.
