Varroa sound
Well here is something new for those that like to buy fancy expensive gadgets. Seen one today at the UBKA conference, it seems to be a simple 14.5kHz sound generator cost buttons to make running of a 12V alarm lead acid battery. Does it work - well these have been around for a while now and not a lot publicity so draw your own conclusions.

I'm nearly tempted to make one for evaluation , so has anyone tried it?

As you suggest - easy enough to make; (piezo transducer might work well at that frequency) however if they had been around for a while, I would assume that news would be out that they actually work.
I wonder what they look like after being propolised?
