This is anecdotal...
but a neighbour of one of my apiaries has an ultrasonic rat repeller in his
loft. Several years ago a swarm entered the loft, then went berserk swarming
out
of the loft, into the house and to the garden, and numerous bees died. He
claims that the rat repeller, which is motion sensitive, and cycles through
various frequencies, drove the bees mad.
That really is for whatever it's worth, if anyone is seriously interested
I'll try find out frequencies etc. What do the bees in your extracting room
do ?

If they don't hear why do we talk to them?
