Resistant white fly in my green house
This year my greenhouse has been infested with a mass of white fly. I have used two different smokes and sprayed with bug clear. They seem to thrive on it. It made no difference at all? I have now cleared my tomatoes and cucumbers, but I still have some stuff in there plus overwintering plants. Bearing in mind the time of year, any ideas apart from tweezers and a hammer, I would much appreciate.
