I have a swarm that has moved into a house about l week ago.  It is between the first and second floor about 3 feet in from the outside wall.  Is there any way beside drumming to remove these bees without killing them. I have built a very good vacuum system for extracting bees but I cannot get to them with it.  Will ultrasonic equipment work on bees.

Any ideas or options would be appreciated.

Thanks,

Gordon Mason
