I have 3 citrus plants which I have overwintered in my conservatory. They look healthy but leaves and stems have small brown bumps on them which I can pick off with a thumbnail (although there are hundreds) and the leaves are covered in a sticky film. Is this scale insect? and what is the best treatment? Systemic treatments will mean I can't eat my fruit!
