I went out to the garden this morning to cut some end of season kale to
bring to some co-workers and discovered they had a sizable infestation
of whitefly. I had checked these same plants on Sunday and they were
fine. So, I think I've caught this at the beginning. I've pulled all the
kale and started spraying everything close by with Safer. What else can
I be doing?

Anyone have any good ORGANIC ways of dealing with whitefly?
