I've been using his methods and not had to treat any of my colonies that are placed on areas of 'high vibrations' for three years . A couple that have ended up in wrong places for various reasons (this last year) did need treating, they will be moved soon.
Varroa counts have not reached more than 6 at anyone one time, using icing sugar dusting. I do use drone culling to a certain extent, especially the colonies that I'm not that impressed with before requeening. Almost no varroa found in 14 of my 16 colonies. Over the last 3 years I've lost only 2 colonies over winter (2012/2013) both to DLQ.
