Hello Kate, Thanks for reply. The polys are outside and the offending beasts are colourless. I,ve suffered from whitefly in the greenhouse and would be able to identify them,but these seem to spring/hop away, returning later. I see they are also in a sheltered bed at the back. The bed and pots are very dry and i wonder if this has any bearing.
