Re: Band heater vaporizer.
I treat from the back of my hives through a hole drilled in the top lip of my bottom board. I do not close the front entrances on my hives. It takes too long, and I can see that that the vapor is permeating my hives completely even with the front entrances open. MY FRONT ENTRANCES ARE 1 INCH BY 3/4 INCH THOUGH. If yours are wide open, you would probably want a reducer.

Just FYI, I am currently in the middle of round of treatments for 18 colonies. I treat Monday and Friday every week. I started Monday, August 27, and my last treatment will be this next Friday, Sept 21. This will probably seem like overkill to some, but I have the time to do it, and I want complete eradication. You should have great results treating 6 times every fifth day.
