I am looking for opinions from people who have had experience using queens that are varroa and/or tracheal mite resistant.

What queens are you using?
Where did you get them?
What have been the results?
Have you had to treat at all?
Do the bees keep the mite count down with out treatment?

Any other info would be appreciated, i.e., mean/gentle, good producers, fast build up, etc.

I think there may be a lot of Beekeepers who would be interested in this.

Thanks, Paul
