British Columbia: Whitefly on roses

I have had for a few years, a serious infestation on Madame Legras de Germain, an old rose. Also on my grapes. I did not spray.

This last year the whitefly migrated to my new David Austin English roses. We don't use pesticides, or haven't. We also keep bees.
Is there any almost harmless spray for the roses or anything I can do about this. Late last summer the roses were not happy and some of the leaves were dropping.

Thank you.
