I have a large heated greenhouse in which I have citrus, peaches, apricots, etc and with which I have a constant battle with scale

Q. I have a large heated greenhouse in which I have citrus, peaches, apricots, etc and with which I have a constant battle with scale. Would your tree glue bands stop further generations from attacking the trees from below?

A: I have never heard of glue bands helping with scale. Adult scale insects are immobile and it is the young which move around the greenhouse i.e. the eggs are laid underneath the scale insects protective covering . The newly hatched nymphs move about the plant until a suitable feeding site is found where they start to feed before transforming into a immobile adults. The best solution is a combination of SB Invigorator – spray 2 or 3 times over a weekly period and then spray with scale nematodes 3 times at 7 day intervals. This will clear any scale already present and then SB invigorator can be used to control any new outbreaks.  Controlling Scale Insect
