I was interested to read about the problems with wax moths. For them to take over a hive, it means the hive is weak. One way to help the bees defend the hive from them is to reduce the size of the opening. Store frames with pulled wax in the freezer. That will keep them safe and kill any wax moth eggs.
Plant Collector, go to YouTube and watch some videos on trap outs. It will give some ideas about taking bees out of a tree or other places.
