I would never argue with a success story. My take on all this is: what if it doesn't work? I have tried for years to keep bees here in my yard, using ferals. They never made it.
I have obtained an instrumentally mated VSH queen from my friend Tom Glenn. That's my next plan. Also, I hope to purchase some mite resistant bees from Mike J.
So my conversation is for the folks who tried going off treatments and lost their bees. Some lost 100%. Basically sucks. How are you going to raise mite resistant bees that way? Nothing to select from!
