I have just inherited hundred of used plastic frames. They have been stored in a barn for the last 3 years.
Most of the drawn comb on the frames has been removed, either by the last owner or from wax moth activity.
No wax moth evidence is currently present on the frames. How can these frames be rehabbed for use? Do they have to
have wax on them before the bees will use them? If so, what is the easiest way to apply it? Any suggestions appreciated!
