Question: I have whiteflies all over my satsuma. I almost hate to bring it indoors. They seem to get worse while it’s inside over the winter.
Answer: Whiteflies are difficult to control. You’re right, they are usually less of a problem when natural predators can work on them outside. You could apply a systemic insecticide (not if the plant has fruit on it), or use yellow sticky traps within your plant’s canopy to capture them.
