I had a horrible whitefly problem in my greenhouse last year. Gah! I had to use chemicals, my g'house is too big. Since I bring in plants from many people to overwinter, the pests come in with those, for the most part. This year I cut everything back pretty hard (as I usually do), and sprayed as I brought the plants in. We'll see how that goes. I need to put up some new yellow stickie papers. I've had some up, but I think they need to be replaced.
