I have just seen clouds of white flies on my cauliflowers! I have never been bothered by them before what can I do to get rid? 

Also do they do a lot of daamage to the plant if they are just left?

You can spray with chemicals if you're into that, or just cover with fleece or Enviromesh to make sure they can't get at your caulis
You could try washing them off if there's not too many caulis involved. 

I just noticed I have them on my cucs in the greenhouse but getting rid of them without recourse to chemicals is not easy.  I'm still gettings cucs so not unduly bothered

Hi BQ,
   I dont use chemicals but will try spraying them with soapy water when I am dealing with the blackfly on the runner beans.

If you can use a hose on a fine spray that might be easier. We can't use hoses on our plots though so we have to use trigger sprays
