I feel impertinent to comment, as I have no experience, but it occurs to me that without some treatment, the mites will breed anyway. So surely any technique, such as this one, that encourages this inevitable breeding to take place in a controlled area from which the resultant un- released mites can later be removed, must be beneficial in itself. Socrates would, I am sure, approve of the logic of this. (.....later in the day, I now see several other much better replies than I can manage, so I'll shut up and just listen!!!!!) -- Alyn W.
