In the opinion of you guys in the know,what is the best treatment for getting rid of the dratted white fly? I'm not particular with method,organic or otherwise,I would just like to rid my polytunnel of the blighters asap. Thank-you for your time.

I have found those sticky yellow traps help in the greenhouse.

Thank-you Aunt Sally and Cob Nut for your replies. Will get on the case as I obviously need to rid my polytunnel of them before the season starts to get into full flow!

Good point fatcat1955, will be growing toms in my polytunnel so FM's will be on my list

I always use the yellow sticky hanging fly papers and also tagetes in my greenhouse and never have a problem.
