>>My guess, under the right envionmental conditions, particularly in

Do tracheal mites reproduce year round? If so, I can see how they wreck havoc with a downsized colony at the end of the winter.
What are the recommended treatments for tracheal mites? I understand formic acid is pretty effective.
