White flies and cold?

Do white flies die when it freezes?
I have some lovely kale from last year, but it has been taken over by whitefly!
I've read up on it a bit, and they don't recommend using poisons cause they get a resistance to them over time.
I've been spraying with water for a couple of days, but, looking at the leaves, I see a lot of the youngsters clumped together on the leaves!
It's only a couple of huge plants, so I'm thinking of picking/washing/cooking and freezing what's left and chopping the suckers down! Nothing else seems to be affected. Nancy
What do you think?
