Essex,
United Kingdom 
The garden of my newly built house is infested with whitefly. I thought this was a greenhouse pest . How can I treat both white and green fly without harming the bees and ladybirds which are also in abundance ? Thanking you in anticipation ,Margaret Simpson.

Provado make a ready to use Organic spray which treats for all of these - never tried it, dont know how good it is. Don't by ordinary Provado bug killer though, it contains a substance that upsets bee colonies.

We use soap on whiteflies here, and it seems to work fine. In fact, it often is the only thing to work, since our whiteflies seem to be immune to most insecticides.
